Some times back, I tried my self-made expo disc on my canon D60 and quekky's D70. To our surprise, after setting the custom white balance (we took the same shot for CWB), we then taking the same picture (the cowboy photo hanging in a corner inside funan mac.), my D60 shows a warmer cast whereas quekky's D70 shows blue cast.
I thought after setting custom white balance (ok, my expo disc may not be 100% correct, but it sets the baseline for comparison) on any brand of digital camera under the same conditions, it should yield the similar, if not same results.
Would appreciate some advice on this issue. Thanks.
