A common outcome when shooting under different lighting is yellowish photo especially when hotel/halls uses tungsten light. A typical photo is as below
Some camera allows shooting in RAW mode and with that you can easily adjust the WB parameters like below
Well the big question that people always ask is do i need to adjust it? The common arguement is, the place is yellowish in colour. Well my reply is yes and no.
Yes, because I feel the above photo, the 2nd one look much better after adjusting.
No, because sometimes the plain one is too plain and you don't give the mood to the photo. Below is a sample of photo with purposely adjusted WB. Some post processing to enhance it.
Photography is an art. There is no clear right or wrong in it.
