Hi i am new to digital photograhy and i had a problem with brightness control whenever i should with my nikon D70s i find the brightness display in the nikon pictureproject seem like over expose but when i open with the windows picture and fax viewer it seem to be just rite so can anyone tell me which viewer give me the correct exposure. The most of the time i share my photo with my friends and relative are using windows picture and fax viewer to see so if i use the picture project to edit my photo then most probaly it will be under expose when view in windows picture and fax viewer so which software should i trust.
