I have been playing with manual quit often lately and Automatic seems to be a no no for me lately... IN Some pictures I notice a tinge of blue.. I know this has to do with the white balance... However, Im not sure HOW to adjust white balance and SEE that it is set correctly to give my pictures the overall god color... With that said.. HOW do you adjust this and KNOW for sure its ok? IS it ok to use the PreAdjusted white balance?
