kenneth_smith7 Posted January 26, 2014 Share Posted January 26, 2014 <p>Well snowflakes and rainbows anyway. We all know you'll never see a Unicorn if you have a camera with you. So why is it when I has down in the ten degree snow shooting the incident light off a snowflake the camera didn't record the colorful light spectrum that my eyes saw?<img src="/bboard//i159.photobucket.com/albums/t151/Alden56/Nospectrum_zpsff2aa67b.jpg" alt="" /></p><div></div> Link to comment Share on other sites More sharing options...
dwight200 Posted January 26, 2014 Share Posted January 26, 2014 <p>Just a guess, but it may have been the aperture. The aperture in your eye is fairly small. I can't see what camera you used here, but many cameras have aperture dimensions significantly larger than the eye. That means the eye subtends a narrower range of angles from the subject. If the colors are due to refraction, they come at you at different angles. If the camera aperture captures a lot of different angles/colors, they all mix together to white.</p> <p><img src="http://small-farm.org/Refraction.jpg" alt="" width="708" height="800" /></p> Link to comment Share on other sites More sharing options...

Since most everyone has a camera in their cell phones these days, I guess Unicorns are doomed.</p> Link to comment Share on other sites More sharing options...

kenneth_smith7 Posted January 28, 2014 Author Share Posted January 28, 2014 <p>Sorry I didn't respond earlier. I thought I had a notification checked but I didn't. <br> Camera was a D7000 with a Nikon PB-5 bellows and a 55 Micro Nikkor f/2.8 AIS set at f/8. I saw the colors with my eye only. Couldn't view the monitor due to the tight hand held unwieldy position due to extreme magnification.<br> And I think the first answer might have it, the bands combined into white light. Fascinating, although I can easily photograph spectrums from oil slicks. I'll try next below freezing snow to stop down and see if I can get the colors.</p> Link to comment Share on other sites More sharing options...
