In this case under tungsten lighting at night, indoors. Since my XS's WB presets weren't giving a good result for shooting in these conditions(my house) I decided to try out Cutom White Balance. As I don't have an 18% Grey or White card, I had to use house hold paper. These are my results, ordered as AUTO WB-white reference-Custom WB: In my kitchen under one tungsten light with AUTO WB Shot of a white napkin under same lighting in same spot Same pills on same spot and lighting now using Custom WB Now I knew I'd get a much better result by setting a Custom WB. But I was still stunned at the difference in tonal range, contrast, etc. Now I really want one of those little Grey cards. Do you guys have any recommendations? How many of you use Custom WB? P.S. I can provide another example under similar lighting with a different subject with different reference shot. Thanks for looking.
