Why does this photo look like this?

GAD, a sidebar on light...

I am right now in the midst of a $300,000+ commercial dispute that boils down to light.

Two samples that look the same as each other under natural light, and, look the same as each other under a particular set of fluorescent lights...look very different when viewed under another set of fluorescent lights.

So, production materials approved in the field don't match when viewed at the office.

Special calibrated light boxes must be used for judging the colors of goods in the marketplace.

Probably has some parallels somehow.

I am in shock. I was right about the light!!

You bet it does N2N Mags Dad. In advertising they often have boxes used just to view colors:

I've seen them in graphic design shops, even clothing design. Matching color from my monitor to my printer is a pain in the butt, but when they match, it's awesome. When they don't, I waste a lot of paper.

Good job Jeannie! Don't go too crazy worrying about the yellow circle. If you had the larger version of the image it would be smoother, AND don't forget that there are two different types of light in that pic, so one of them will have to "give in" to the other at some point. You could layer out the yellow and work on that if you wanted to.

Notice also that the spot that's yellow in your fixed version is the only spot that was white in the original. Coincidence? I think not.

Not trying to hijack here, but that's why I always insist the architect approve individual samples, and have the architect keep one approved drawdown in his/her file, and I keep another onsite. I also arrange for NEW spec'd lamps to be available for comparison viewing. NEW because color values emitted change as the lamp ages, particularly in the case of halogens.

Also, with flourescents, color values, while spec'd out by the mfr, differ vastly from mfr to mfr, so a "warm white" by Sylvania will look a LOT different than a "warm white" by GE. Don't even let me get started on OSRAM....

Sorry, we now return you to your photographic brain teasers....
