For those of you who're unsure whether your iPhone 4's camera has the yellowing effect from the LED flash on your camera, here is a comparison photo of my original iPhone 4 with yellowing and my replacement that doesn't have this issue. To test it for yourself, go into a dark room and make sure flash is on and take a picture, either of yourself or your hand. If you see more yellowing than normal, you have this issue; if not, you're fine. I call it the Jaundice Effect.
All of my pictures in my apartment look insanely yellow. Outside they are beautiful and in other artificial lighting, but inside my apartment they are **** yellow. It's ridiculous.
Damn it seems I may need to replace my i4. Stupid jaundice. I'll wait until 4.1 to make sure. I really hope I can keep my launch day i4 as long as possible.
Sorry, can't resist! You actually take pictures in the bathroom? LOL! :-)
I luckily don't have the jaundice problem, either. Must just be some defective units. I have flash glare from my case something fierce with the first two cases I tried, but I guess the third time is the charm. It's not perfect, but it works for what I need it to! Love the camera on this sucker!
You have to take into account the type of lighting you have indoors where you are actually taking the pictures. All light sources have a different "temperature" which will affect colour balance. For example ordinary tungsten bulbs and the new "energy saving bulbs" - also know as compact fluorescents have a different temp. CFL's do produce a yellowing of a picture.
Some/most stand alone cameras have better balance controls than the iP4.
