I take a lot of photos with my iPhone, primarily for eBay. I'll take product photos in my dining room, which is well lit, with the products sitting on a white poster board. A very annoying problem I've been having seems to be related to how my phone is detecting the light. Depending on how it "senses" the light I will either get a light shot or a much darker shot. I don't want to go in and adjust the brightness on each picture I take. In addition, if I use the magic wand and fix it, the changes don't transfer to the eBay app. So that doesn't work either. I'd like for the photos to come out right the first time. Should I be using a different app to take my pictures, or is there anything I can do differently to avoid this problem?
