Here’s an awesome milestone in my electronic music-making pursuits: this Thursday a copy of Reason 6.5 showed up on the doorstep! Having used every update back to 2.0, it’s very exciting to have my own legit copy of the latest and greatest iteration. Probably the best part about Reason 6 is that it added support for recording external sounds directly into the program to layer them on top of your tracks; the lack of this was the single biggest downfall of previous versions. They’ve changed several other things and added some new devices which I’ll need to explore as well… it’s time for me to spend some quality time here and do some learning. PUMPED UP!

One of the first cosmological images which really and truly blew my mind as a young adult was the Hubble Ultra-Deep Field. Basically the idea was “Hey, what happens if we take our most powerful telescope and point it somewhere that’s pretty much empty and just stare at that spot for a really long time. What would we see?” The answer to that question was “We see somewhere in the neighborhood of 10,000 very distant galaxies.” Pause and let that marinate for a moment.
Here is a closeup on one small area of the image, a random part that I thought looked cool:
For a long time I left that as the wallpaper for my computer at work and I’d come in every morning and stare at the image while my slow computer took forever to finish loading windows. What was cool about having it as the wallpaper I had to look at while I waited for the machine to become usable was just how much there is to look at in there. As long as I stared at it, I’m certain there’s oodles of things I still didn’t notice. Looking at it first thing in the morning too, when the mind is raw and still gradually awakening surely added some awe to the effect as well. It’s staring into an abyss. Staring into infinity. And knowing that it stares back at you too…
As a humorous aside, I’ll note that the “Hubble Ultra-Deep Field” is actually the sucessor to the “Hubble Deep Field” which showed a different region in space. And this new image, the “Hubble Extreme-Deep Field” is a closeup of a smaller section within the Ultra-Deep Field image, adding around 5,500 galaxies to the original 10,000+. When the James Webb Space Telescope goes online, they have plans to image the same area with it’s mighty Infrared sensing capability. What will that image be called? The Ultra-Extreme Uber-Deep Field Tournament Edition Plus. Director’s cut. Enhanced, expanded edition. Two. Strikes Back. Reloaded. Chopped and Screwed. Remix. Turbo.
Whatever, it doesn’t matter what it’s called. Just, everyone, do me a favor: full rez this new baby and spend at least two minutes staring, thinking about what it shows:
Everything on the internet, everything in a book, everything you’ve ever heard, learned, imagined, or even dreamed, in the most remote recess of your subconscious, is all within the realm of the ‘Earth’ experience. And Earth is a single, small terrestrial planet out in some sleepy backwater arm of the Milky Way, a perfectly average spiral galaxy with about 300 billion stars, and about as many planets, with maybe 10 billion of these being in the goldilocks “habitable” zone. Or at least habitable to “life as we know it”. Nevermind moons, nevermind thermally-supported life, nevermind ‘Steppenwolf’ planets that were flung from their parent stars. If the entire breadth of human knowledge, emotion, and experience resides within our differential-unit-small grain of sand that’s floating in the Milky Way swimming pool, then try to concieve of the vast diversity of lifeforms, cultures, natural wonders, and sub-realities residing within the oceanic field of view of this image, depicting thousands upon thousands of distant galaxies. Try to imagine traveling there, surveying them. Imagine exploring just a handful of those galaxies and chronicling the habits of their residents.
How could we explore it? First we’d need to aggressively master interplanetary voyages, remote communication and colonization. Fly probes and listening devices to the Kuiper Belt. Mount them to passing comets for a long voyage back out to the Oort cloud. Use those to learn about the radiation and galactic wind in interstellar space. Develop shielding, life prolonging and hybernation capabilities for deep space travel. Contact alien cultures within our own galaxy and master inter-species diplomacy. Develop non-invasive, non-destructive ways to study primitive life still early in its evolutionary tree. Catch the best bacteria to help us live longer, retain more knowledge. Authoritively chronicle the Milky Way with billion-year data storage capability. Pool resources with other intelligences to build intergalactic ships or probes. Scatter them in all directions to search for points of interest. Then, finally, research ways to reach the most distant of galactic neighborhoods like the ones we see in these pictures. My point: The actual exploration of these places is not something that’s a few ‘ages’ away in terms of a civilization. Exploring these places is an act for intelligences unthinkably more sophisticated than our own… But we can dream of it.
When I look at this, I like to focus in on individual places and try to imagine what might be there. I like to find a pretty looking galaxy and think about what planets might be inside of it. Or sometimes find a teeny sub-pixel dot and wonder if that less-than-a-pixel point is a whole giant supergalaxy, burgeoning with life forms, interstellar commerce & conflict, culture & craftsmanship. Maybe these two galaxies colliding are locked in an interspecies war millions of years long. Maybe they’ve evolved organic-electronic synthetic intelligences that can instantly teleport between host bodies, allowing them to be anywhere their race has ever traveled instantaneously. I wonder what their music sounds like. I wonder what senses they have. Can they “see” radio waves? Does their culture have money, or government? I wonder what “pleasure” or “sex” means to them? Or consciousness? I wonder what THEIR telescopes have discovered about the formation of the cosmos. Does it look “the same in all directions” from the far-far edge of what we humans can see?
It’s fun to try envisioning all these things. And then humorous, in a zen sort of way, genuinely humorous, knowing that it’s impossible. You can’t. You’re looking at something so much bigger, ancient, and wilder than the capability of the feeble human brain to comprehend. The are not human words in any language to meaningfully describe what any of these Hubble Fields show. These images, obscured by the thick, nearly-opaque veil of distance, give the most fuzzy, teasing glimpse of something beyond us. Something beyond even what our most distant descendant will ever become. I find that deeply exciting. This picture shows, unquestionably, indisputably, that the universe has more to explore than is possible to explore. What better reason to be alive in this cosmos?
The first man to walk on the moon died yesterday. That’s a guy whose name will be printed in history books as long as humankind ever has them.
Will there come a time when all people who’ve walked on the face of another world are no longer alive? That’s a sad thought. I hope that we get some fresh boots back into deep space sooner than later. Armstrong would certainly want it no other way…
Alright sportsfans, it’s the real-live JB back from my moving-induced hiatus! I hope you’ve enjoyed the automated version of me, posting all those svelte wine labels and wild album covers, but it’s time to get back to business with some serious text blocks. Yeah that’s right, I hope you’re ready to read instead of gawk, because I’m about to max out type here.
Exciting to be in a new house, although the next several months will undoubtedly be a battle of current self versus former self, asking, hmm, if I were me, what box would I put the pruning shears into? Good question, current self!
I think I may also branch out into some home-improvement related postings, as I learn things. More on that later…
Well here we are folks, blogpost # 200. It’s nice milestone to be hitting!
Hmm, pressure’s on, better bust out something cool… how about a photo I took…… of the moon??
Shot with Canon 100-300mm @ 300 and cropped (1:1 original resolution shown). 1/125th @ f/11 ISO 100. w/ a Canon T3i. Mirror lockup and ten second delay on the shutter. Phase based autofocus (through the viewfinder). Light enhancements in CS5.
It occurred to me that I’d never taken my 100-300mm zoom outside on a clear night at tried snapping shots of the moon at the long end of the lens. What you see here is a 100% resolution crop. So this is the max resolving power of my erm, best refractor, at the moment, coupled with the T3i’s max 18MP setting. I’d say it came out pretty well.
And speaking of new phases, I will be moving soon! Which means a whole lot less time on the computer and thereby a whole lot less time available for posting on here for a while. Fortunately I’m way, way, way behind on posting my Primo Vino Art, so there will be a bountiful explosion of images for you photography nuts and oenophiles. I intend to schedule these posts in advance, so while I am busy shuffling boxes around there will still be a steady stream of things to look at.
Speaking of things to look at, some of you may have noticed that the header image at the top of this blog has been changing recently. I happened upon a really sweet little piece of code that allows you to setup a directory full of images, and then randomly display any one of them. Currently there are 4 different header images that appear at random. Over time, I intend to continue expanding this until there’s like 10-20 different ones. Eventually the background may become randomized as well. Variety! It’s the spice of life. And we all know spice expands consciousness.
Feels good to hit 200! Cheers people!
As of about a week ago, I have an awe-inspiring new arrow in my artistic quiver, and one that I really should have acquired ages ago: a USB keyboard with knobs, drum pads, and sliders. Specifically, the Novation Impulse 61. I’ve had a full-size 88-key digital piano for many years and it was a superb instrument for learning keyboards, and to a limited extent, producing with Reason. The problem was that no matter what I tried, I could never seem to overcome the problem of MIDI latency (ie lag between a keypress and the actual sound). Over 3 or 4 different computer builds and windows installs, there was always some kind of latency. Which was a real bummer, because it meant I could play chords and figure out notes for a melody, but I could never input any rhythmic passage into Reason; be it a drumbeat, a synth line, a bassline, a chord stab, anything.
At this stage in my musical life, I don’t see myself sitting at a piano and leaning to master it purely with no accompaniment. However, I do have a whole ton of fun making tracks in Propellerheads Reason, and this is definitely a way that I see myself growing more comfortable with the keyboard and maybe even learning a pinch of music theory as well. Having a USB keyboard with no latency is a huge, huge advancement toward that end. Plus, having those assignable buttons, knobs, and sliders to tweak Reason in realtime is über-schweet.I may even call this the beginning of a new epoch in the compositions I make for fun, and by extension, my overall musicianship.
Going forward, my goals here are to use this thing pretty much as often as I can, and also to try to post more music online with it. Historically, I always seem to obsess too much over having a track be ‘perfect’. This also leads to the tendency to start things but never finish them. There’s literally hundreds and hundreds of Reason tracks on my hard drive that started out real cool but then fizzled, as I couldn’t figure out what direction to take. I want this new epoch to be the end of the ‘beat graveyard’ so to speak. I’m really hoping this keyboard will be an impetus to break me out of the same ways of thinking, to get me more in the habit of following through, and just finishing compositions a whole lot more. This will need to be a change in mindset as well.
All that said, I intend to start posting a lot more musical “sketches” on here–Reason compositions that aren’t “polished” but can be called “good enough”. I have this mental resistance to the phrase “good enough”… like it’s giving up on how good things could be. But you know what? “Good enough” is a whole lot cooler than “nothing”!! Here’s to turning the page, people!
There’s been a lot of talk lately about the budget cuts facing NASA, and indeed they are deep, and correspondingly tragic. I’m sure the space crowd around here is already well versed, so we’ll skip the rehash.
But I do want to remind us all that there are ultra-sweet projects nearing fruition: budget cuts can’t stop Curiousity, which is well on its way to the red planet. The biggest, baddest rover that ever was! That thing is going to get new high scores, starting in August.
And, despite gobbling up all the money that could have been used for myriad enticing small projects, the James Webb Space Telescope will be built and launched. One could make a very strong case that this was the wrong decision, in light of the opportunity costs in scrapped missions the Webb consumed, but I say hey, what recent space project has done more to raise public interest in astronomy than Hubble? I mean, I’d put Hubble at #2 behind the Apollo missions in terms of ability to get people fired up and fascinated with the sky. Having a brand new, next generation eye up in space is going to create better images than ever before. Pretty pictures are important, to capture the imaginations of new generations.
In the end, it is sad that our national priorities are what they are–jeez, on MANY levels! As the SETI infographic highlighted, there is a massive disconnect between planning for an inevitable future (ie space exploration/research) versus how our money/resources get burned away at the altar of short-term profit (war profiteerism/exploitation of natural resources with disregard to the planet/etc)
Out of everything I’ve done on this website, that infographic brought way more people through the door than everything else combined. Even almost a year later there is a steady trickle of visitors every single day who come here to look at that. What does that say? I’d venture it says there’s a large group of people out there who agree that our destiny, as an evolving lifeform, lies beyond the shore of the cosmic ocean, here on Earth. And by extension, it means that our survival depends on knowing the Universe. How well can we explore it, exploit its treasures and avoid its dangers? The answer to our ultimate fate lies in how much effort we are willing to devote into these things.
What would it take to shift our societal priorities away from petty conflicts and toward the next horizon? There’s no way of saying. But Curiosity and James Webb are two powerful steps toward raising public awareness that hey, there is this giant thing called the Cosmos; it’s all around us and inconcievably more vast, richer, and filled with more splendor than Earth alone could ever hold. Seriously. We should go check that out. We should be part of that. To the people already abundantly aware of it, it’s easy to feel like maaaan, why aren’t we doing this already? Why did we cancel Apollo? Why haven’t we set foot on Mars yet? Why does our brain power go to work on Wall Street, instead of at JPL? Don’t they understand that we have places to GO?
I definitely feel that myself. But I also remind myself that it’s still less than one century since the theory of “island universes” became an accepted idea. It takes time to build concensus. It took eons for life to evolve from the sea to the land, and it will take perhaps a long time for humankind’s larger consciousness to grasp what the revelations of the last century in astronomy actually means for us all. I have to admit, I feel it does say something dark and disturbing about our society that we should develop fusion bombs well before fusion powerplants. But I keep hope that as James Webb lifts the veil from the great cosmic metropolis stretching to infinity in all directions, and as Curiousity digs to find martian secrets in our veritable backyard, it will open more eyes.
Open more eyes to the unavoidable truth that the Universe is beyond our vocabulary for Ancient, Boundless, and Beautiful. It has existed for longer than the word Epochs can articulate and it will continue unaffected when we are gone. An extension of our word for “nature,” the cosmos is equally stuffed to the brim with magnificence as it is with impartiality toward the folly of its minor tenants. The sooner we awaken to our own frailty and societally grok the rarity, the sacredness of life, the better our chances to gain that lucky opportunity to be part of this cosmos, to savor it and chronicle it.
To me, that’s the truth that Webb will awaken in more people. Curiosity is the other prong; doing. Being able to know what’s out there and prepare to go ourselves. That’s the part where the “homo” genus get to, you know, not become extict someday. But in order to get there, we need to prioritize it. We need the vision to see. Fortunately we’re going to get the most powerful set of eyeglasses yet, launching around 2018………
Pentax is blowing up the interwebs this week with news of their newest sweet photo machine, the K-01. New sweet photo machines are a dime-a-dozen, but what makes this one interesting is that it’s the first mirrorless interchangable lens camera (we’re going to stick with the acronym MILC here) that actually shares a lens mount with their normal SLRs, meaning you can attach any of your existing K-mount lenses right on to this baby. Now that’s progress! No need to repurchase thousands of dollars in precious glass to be totally outfitted.
You’ll also notice it’s offered with a shockingly thin (read: skimpy?) 40 f/2.8 prime. That’s an odd novelty, but with glass that tiny, does it actually take decent images? Anyway, I don’t care much about that, back to the body–It’s cool to finally see someone make a mirrorless camera that doesn’t demand a whole new army of lenses. It’s about time!
And still no MILC from Canon… I’m waiting fellas!
Runner up for interesting new camera in the mirrorless world would be that Fujifilm X-Pro1. It’s predecessor, the X100, was featured on here a while back and remains on the short list of extreeeemely lust-worthy photo gear that I would totally buy if it were only a little more affordable. The X-Pro1 would probably get a whole post devoted solely to it as well, if it weren’t even further into the netherworld of unaffordability. At $1700 for the BODY ONLY, I wonder how many units of this thing Fuji is going to be pushing. For that price, you could get a rock solid Canon or Nikon DSLR AND a lot of great glass too. Unfortunate. But it does have enough unique features that I want to blab about it for a minute. Let’s start with some choice blurbs from the official press release:
The new color filter array paves the way for an ideal sensor that does not need an optical low-pass filter. While the optical low-pass filter is indispensable for the reduction of moiré and false color generated by conventional sensors, it also degrades resolution. Fujifilm has developed a new color filter array that is inspired by the random arrangement of fine film grain, removing the need for an optical low-pass filter to solve moiré and false color issues. In the array, RGB pixels are arranged in 6×6 pixel sets with high aperiodicity (randomness). Increasing the degree of randomness eliminates the fundamental cause of moiré and false colors – a problem that occurs in conventional arrays when shooting stripes and other repeating patterns. The presence of an R, G and B pixel in every vertical and horizontal pixel series minimizes the generation of false colors and delivers higher color reproduction. blurb #2:
Extending Fujifilm’s photo film legacy
In film cameras, capturing multiple exposures is the unique photographic technique of superimposing one image on another by double exposing a single frame of film. Through advanced digital processing the X-Pro1 can simulate this technique by simply selecting the Multiple Exposure mode and taking the first shot. By viewing the image via the Hybrid Multi Viewfinder or on the LCD screen, you can see how the finished multiple exposure will look and then precisely frame the second shot. Further enhancements have been made to the Film Simulation modes with the new Professional Color Negative Film Modes (Pro Neg. Std and Pro Neg. Hi) designed for X-Pro1 users working in the studio. The X-Pro1 also offers Film Simulation bracketing, along with AE, Dynamic and ISO bracketing; plus the ability to capture the colors and tonal qualities of popular FUJIFILM emulsions through the vibrant colors of Velvia, the softer skin tones of ASTIA and the natural look of PROVIA.
That multiple exposure thing is pretty rad. Every camera should have that, using preview on the LCD. That’s science. The coolest thing about this camera is definitely the color filter array though. Okay kids, put on your nerd caps, cuz shiz is about to get hardcore up in here:
Every digital camera uses an image sensor to collect the photons (light) that make up the picture. Since the sensor itself cannot discriminate colors, filters are used to split the light into RGB (red, blue, & green) components. By combining RGB in different combinations, you can then spell out any color imaginable. Old school photographic color film accomplished the same idea by having (at least) 3 seperate layers of silver halide salts which were dyed differently. Since film was a chemical/analog process, those salt crystals weren’t arranged in any sort of perfectly aligned matrix, they were just scattered all over, however they happened to fall. The characteristics of any given film (contrast, sensitivity, resolution) were determined by the crystal sizes and the amounts of the silver halide for each different color layer. Fancier films had up to 12 different layers used to reproduce colors! So it wasn’t just RGB, it was a whole lot of different colors being combined, and each “pixel” in the film was of variable size. Click the image of those Kodak T-grain silver halide crystals to see more Scanning Electron Microscope (SEM) images of different films.
To obtain digital color images, almost all sensors use the standard 2×2 “bayer” color filter, named after a clever Kodak engineer who came up with the scheme during the 70s. (If you’re wondering, Bryce Bayer chose to use an extra green pixel to emulate the human eye’s sensitivity to green light, which is kinda neat!) So nearly every digital camera uses this method of light collection, and even those rare cameras which deviate from the standard color filter configuration still have some kind of repeating, contant pattern. Although it’s not completely clear from the Fuji PR-speak, if their color filters really are randomized across the whole sensor area, woah, that is a major difference in the way light is gathered… and a pretty ingenius mimicry of analog. As a giant in the tradition of film and therefore owner of masterful knowledge upon the characteristics of it, seeing Fuji bring the lessons learned over decades of experience in color reproduction using silver halide emulsions to bear in the new digital era is… way cool. If anyone can do it, it’s them (or Kodak?).
The story of the transition between the analog epoch and the digital epoch is a tale chock full of “back to the future”-isms. In the sense that as digital technology gets better and better, the goal seems to be emulating the way analog things used to be. We see this is audio mastering (see TRacks-tube/tape emulation mastering software), audio reproduction (vacuum tube pre-amp stereos, and progressively higher sample rates to recreate a more ‘analog’ waveform), musical instruments (amps and effects pedals that strive to recreate the analog ‘warmth’, synthesizers that model their vintage predecessors), and even video games with roms and emulators built to resurrect the early days of gaming. To me, it makes perfect sense that photography, when the technology gets good enough, will undergo this same trend of digital modeling to recreate an analog era gone by.
Right along those lines, Fuji’s film simulation modes are an ultra-sweet concept that I have seriously been wishing someone would do for many years now. I wonder how those work, exactly… searching for information doesn’t turn up any explanation; I’d be willing to bet that the only difference between the three film simulation modes are simple tweaks to contrast and saturation. The example images shown on this excellent webpage would seem to support that theory. Although it’s complex to compare film ‘resolution’ to an equivalent digital resolution, analog film has somewhere between 15-25 megapixels of ‘resolution’ depending on who you ask. My 18MP Canon t3i starts to inch into this territory. As sensor design pushes even further into the higher megapixels, it’d be really cool to see the characteristics of old school film emulsions replicated not just at the post-processing (software) stage, but at the light-acquisition (sensor/color-filter) stage. Software enhancements are never going to beat photoshop at its own game… but hardware that captures color in a new way? That would be an innovation.
What would it take to truly create an honest digital carbon-copy of film emulsion? You’d need a variable color filter and as many megapixels as you could throw at it. As in, a color filter where you could actively switch which pixels recieve which color, and do it on the fly. We’d be aiming to mimic the salt crystals as you see in the SEM image, with variable sizes and variable locations for each individual exposure. You’d have some kind of randomization that would rearrange the configuration every time a new photo is taken, within a given set of parameters for each different film emulsion. To really nail it, you’d also want to not just use RGB in your color filter, but a larger variety of color shades to mimic the dyes from many-layered emulsions.
I lazily mocked up the idea here with a grid over an SEM image of Kodak Portra 160VC Professional portrait negative film. Average grain size: 1μm. I only colored in some film grains because it would take forever to do the whole thing and I got tired of clicking. I did RGB and CYM(K) with a lot of K, I guess. But you could use many combinations of colors in your color filter, both echoing classic film emulsions, or even getting creative with more funky configurations.
That kind of light capturing would offer something you could never do in photoshop, due to the fact that it would change the way the actual sensor is classifying colors of photons which make an image *as they come in*. I have no idea how one could create a variable or “active” color-filter, but man, if you could do that, it would open up incredible possibilities in the way light is captured. Think ultraviolet and infrared too. It’s all conjecture, but I find this stuff awesome to daydream about.
The Nikon J1 is the company’s first mirrorless interchangable lens camera (MILC). That in itself is pretty exciting. What with digital viewfinders, live view, and the new emphasis on movie modes in high end cameras, it’s cool to see the elimination of the mirror and pentaprism format of SLRs. Just extra weight and bulk really. I am ALL for chopping out any of these obsolete bits. Pop Photo gives a great rundown of test shots they captured with the J1, check it out.
Olympus and Pentax have been barking up the mirrorless interchangable lens format tree for a while now, and the retro-rangerfinder-esque stylings of their Micro 4/3rds format have major sex appeal for photography geeks. It’s super cool to see Nikon finally stepping into the ring (because that means now Canon has to as well, and I own Canon lenses!) But like the micro 4/3rds cameras, big-boy Nikon’s first offering in this vein comes with some whopping caveats:
1. You can use your existing F mount lenses, but only with an adapter. It’s disappointing that this camera isn’t F-native.
2. It’s got a crop factor of 2.7. Ouch. That means that your 28mm lens is now equivalent to a shocking 75mm. BOOM, your wide angle is insta-telephotoized! What?!? Jeez!
3. That crop factor is, of course, due to a smaller than APS-C sized sensor. Hrmmmm. Small sensors are a drag. They mean poor light gathering ability at equivalent apertures, reduced bokeh affect at equivalent apertures, poor high ISO performance and by extension noisy, grainy, fuzzy images, when compared to their APS-C brethren.
The second point here may really be the killer, as it essentially means you need to buy new lenses for this camera. Good luck getting a true wide angle below a full frame equivalent of 27mm. Nikon’s got a pancake 10mm that comes out in conjunction with the J1, but how long will it be before you can get something like my canon 10-24mm offers me? (16-38mm in full-frame equivalence) Probably never. No superwide. That’s sad.
It’s a sign that the winds of change are blowing when Nikon makes their first mirrorless interchangeable lens camera. MILCs are lighter, smaller, and a logical step in the evolution of cameras. Unfortunately it seems like it’s still going to be a long time before a guy like me would ever want to take the plunge with one of these, mostly due to that staggering list of compromises above. I’ll check back in when Canon makes a MILC with (at least) an APS-C sized sensor. Now THAT would be a camera I’d get truly excited for!
