Photograph the prismatic effect of a CD. Easy Challenging!
Many moons ago, I purchased my very first digital camera. After using the camera for just a few minutes, I was swept away with "instant photographic gratification" (getting to see the results right away). Anyway, one of the things that I toyed with photographing, was a CD. I loved to tilt the disc in different directions - letting different colored prismatic effects skitter off of its polished surface. I vowed, that one day when I owned a better digital camera that I would try and improve upon the results. Today, approximately 10 years later (and no, it hasn't taken me that long to buy a better camera!), I try to repeat my results.
You would think that going about recording those intense colors would be easy but I soon found out that my original idea of photographing a rainbow reflected onto a white surface couldn't be accomplished with the low angle of the setting sun this evening. So onto plan "B" - I next try to get a decent shot capturing the colors coming directly off of the compact disc. Easy right? Wrong! The first thing that I notice is that my exposure is all over the place. I finally determine that for this setup, I need to dial in a minus 1.3 exposure compensation to get in the ballpark. That seems to help but one of the things that I notice is my colors are not as great as what I see with my eye. Suspecting that the auto white balance is the problem, I next dial into my Nikon D700 an adjustment for the daylight white balance setting. That seems to do the trick and suddenly the colors just start to "pop." Well it still wasn't that easy. After dozens of shots, I finally got several that I thought would be publishable.
Next, after a brief edit in Photo Mechanic, I took my selects into Adobe Lightroom where I made some subtle adjustments. It would have been tempting to just say "I'll fix it all in post processing" but I really wanted to challenge my ability to get this shot "in-camera", as they say. The final shot had just a slight black adjustment in Lightroom and a little bit of contrast tweaking.
This shot was taken with a Nikon D700 and 35mm f2.0 lens set at @ f5 for 1/125 second at 640 ISO with an exposure compensation of -1.3 dialed into the camera. (please click on the image above to enlarge it)
