Keeping White White. .. Hello .. . I am going to be taking some senior and family pics soon and will want to use a white background in a few of them . . . some will have alot of the background in the photo . .. my biggest problem is keeping the white white . .. it always wants to take on a gray or bluish cast to it especially where the muslin overlaps and stuff. . . do I need seamless paper, better muslin, etc? or is it the white balance on my camera? I have a Minolta Maxxum 7D and have tried using the custom white balance setting but it doesn't seem to help much . . . I will be using Novatron lights a 3 head set. . . will this help? I can't afford to buy alot of backdrops right now so am trying to go with affordable muslin . . . any help is greatly appreciated.

Keeping white "white" has always presented a problem. Here's a simple solution - After you have your background set the way you want it, measure the light falling on the white background part. It needs to be at least 2.5 stops brighter than your exposure, and no more than 3.5 stops brighter. This will keep it white. Color casts occur when your printer did not get the color balance right, but keeping it 2.5 - 3.5 stops brighter will help eliminate any color casts. Michael H. Cothran www.mhcphoto.net

Thanks Michael! Do you mean to use my EV exposure and go +2.5?? I will also be using a 3 light set(Novatron w/ umbrellas). Will this help at all?

a smooth surface needs only at least 1-1&1/2 over to be white. Unless your background isn't really white to start with
