You check the white balance a couple of ways. First, just look at the shot and see if it has a colour cast, it might look too yellow, or too red, or too blue. The reason I mentioned white balance was because this shot looked yellowish to me. But you might have intended it that way;
The other way is to load it into photoshop and take a colour sample of a part of the photo you know should be white (for example a sheet)... see if the rgb value reads as '255,255,255' or similar, all the numbers should be the same, for example 240,239,241 would be slightly grey, but it'd still be okay. If it's something like 210,255,220 then you might have a white balance problem.
But the best way to avoid messing about with white balance in post processing is to get it correct when you take the shot. :) |
