    New Infrared Shooting, March 2015


    2015 - 04.12

    Happy to report that I’ve finally gotten out and done some more shooting on my Infrared-converted Canon XTi.  I don’t use this camera near enough so when we planned a camping trip, I knew this was my chance to get some great captures out in nature, where the IR SLR really shines.  Here’s a gallery of my favorites.  Some are color-shifted to appear blue instead of red, a few I left red and one is black’n’white.  Enjoy:

     

    First Infrared Timelapse Video


    2014 - 03.30

    So I actually made this a long time ago but am just now getting around to posting it.  It’s a short video of 4 timelapses that I shot on my infrared-converted Canon XTi.  One really important trick which allowed me to do this easily was told to me by the guy who did the conversion for me: take a photo of green leaves or grass, preferrably blurred out.  Then use that image as the source for a custom white balance.  Now if you take a photo using that custom white balance, it looks exactly as you see in the video!  No processing required, no color shifting.  Now that is a convenient tip!

    First IR Timelapse from Microcosmologist on Vimeo.

    There’s also a color night sky timelapse from the T3i in there, shot on the night I proposed to my wife.  Obviously pretty special to me!  The sky looks really awesome in that IR landscape shot.  I want to do some more timelapses like this with moving clouds since the sky shows up so contrasty and dark in IR.

    First IR light for the XTi


    2013 - 03.31

    So it’s nothing too amazing yet, but here is the first alright looking shot from my Canon XTi which was recently modified with the removal of the internal Infrared-block glass that covers the sensor.  I used a 720nm filter to block all visible light.  So nothing but infrared here.  Not really an amazing shot but I’m pleased with how the plants look nice and white.  I need to play with it more and maybe try a timelapse if I can find a cool subject.  But hey, it’s working, neat!!

    I did a relatively mild post processing on it.  Since it was at sunset, it wasn’t a good candidate for the red/blue channel swap like people do to make the sky look blue.  That’s more suited to afternoon images.  I still have a lot to learn when it comes to the subtleties of IR post-processing.  But I’ve started learning and that’s sweet.

    What’s redder than red?


    2013 - 03.02

    Ever since I got my wonderful Canon T3i a couple years ago (which I STILL think is the sweet-spot in DSLR price/performance/features), I’ve had a perfectly good 10MP Canon XTi body which has been essentially gathering dust.  What to do about this…. I could sell it, although unfortunately, older generations of DSLR bodies depreciate pretty severely  in spite of the fact that it’s still eminently capable.

    A better option: convert it to an Infrared body.  This procedure can be a DIY modification, although it is NOT for the faint of heart.  I’d been thinking about this for a long time so I was excited when it came up in conversation that a coworker of mine repairs/resells DSLRs as a hobby.  It sounds like this might actually happen sometime in the next few months.

    In the meantime, I noticed this really badass timelapse video shot with an infrared DSLR:

    There’s a great explanation on Bad Astronomy of why thing appear they way they do in infrared.  Basically plants reflect a lot more infrared light than any other color–including green!  When you get these photos out of the camera, they appear almost all red in color, so heavy-duty post-processing is needed to get these greyscale scenes with blue skies.  I’ll need to learn about all that to get to the point of making videos like the one shown above, but I don’t think it’s anything beyond my abilities.  Time will tell, but it’d be awesome to make something like this…
