I am trying to practice some and I have lined up some informal shoots of children and families. I will be either at the families homes or at other locations. I have the 430 exII and the 580 exII.
I think for family shots on location and for shots of children it seems best to use less equipment to keep everyone comfortable.
So for family shots, to candids of kids, and newborn sessions what kind of set up do you use? Do you try to use mostly ambient or do you use lighting to wash out backgrounds if necessary? Any tidbits of info or advice on this would be great. Examples of shots and what you did for lighting would be great too!
Also (and if this should be asked somewhere else please redirect) I feel like my 40D underexposes quite a bit but I don't really know what to do about that except to just go into manual mode which is what I have been doing lately.
