I got the new iphone 4 on 6/24 and the next day I bought an "ifrogz" case for it. That evening I was taking flash photos with the new phone and noticed a blue haze on the photos. I took several photos indoors using the flash with the same results. I then took the case off and took flash photos with no problems, no blue haze. I then tried several more flash photos, first with the case on, then with case off and each time got blue haze with case on and no problems with case off. (I made sure that the case was on correctly each time with the camera lens and flash unobstructed) I met with Apple Genius person and she was unable to reproduce problem I had, but she took flash photos in well lit areas. Later that evening I found that this issue occurs with cover on in low light environment. Has anyone else had this problem??
Yes, I am experiencing the same problem too. I noticed a blue haze on all the photos I took when using the flash. I think I am having exactly the same problem that you are having. I am glad I am not the only one.
What brand case was your phone in and what color? I'm waiting for a clear hard case that I ordered on ebay to be delivered and see if this makes a difference. Also, I'm waiting to get a few more replies from people having the same issue and then I take copies of these messages to the Apple store.
I am having the exact same problem. Bought 2 cases off eBay (white and green) got white and green haze on photos taken with case on in low light but not when I took the case off. So, I went to the AT&T store and bought an ifrogz case. They said I wouldn't have the same problem but I still do....
I am having this problem with the incipo cases that AT&T sold me. I emailed incipio - I will post their reply.
Griffin has already remade cases and are replacing the first run. Apparently this is because Apple did not provide any case makes with a phone prior to the release, so they could not optimize the cuts on the case. If you get a griffin case they will make good, hopefully incipio does the right thing as well.
Same Problem. I have 2 Incipio cases. Maybe They are too thick? Perhaps only a thin gel-case will work? I still have my receipt so I'm returning them to At&T. I guess we will see from there what they have available.
So i had the same problem and thought it was another "bug" till I read these forums. To the people ordering a clear case your probably still gonna have this problem. I had left the factory clear film on the back and was getting blue hazy photos so it's probably thie light reflecting off the film/covers/cases back into the camera lens. So when I took it off I had no problem, so I would imagine a clear case would do the same thing! Hope this helps someone like it did me 🙂 
I'm having the same problem. I bought 3 different iFrog cases and if I take a picture in REALLY low light with the flash and the case on, i get the smoky haze on the picture. I can remove the case and take the exact same picture and it's perfect. So the cases definitely have something to do with interfering with the flash to case the haze. I just ordered a bumper from Apple so there won't be anything on the back to interfere and I hope that resolves the problem because the camera and flash actually produce pretty good pictures.
Hi Sacbombero here again (I started this discussion). I just received a case from a Hong Kong co. that I found on ebay. It's a unique design; it's a combination of a hard clear plastic that covers the back of the phone including the opening for the camera lens and flash and opening for "Apple" logo. The remainder of the case is a more flexible, solid black plastic that goes around the exterior antenna and part of the back of phone. I used the flash with case on and had no problems with photos. I'm wondering if the answer is a clear plastic around the flash and camera.
Opps, spoke too soon. Try flash photos, with case on, again this evening with same negative results as the first time. Still getting haze on flash photos with case on.
I had read about some of the problems people were having with the haze in flash photos from the case. With this in mind I purposely bought a case that had a clear back, but it is clear plastic and still causes the flash to reflect into the photo. My wife bought a Speck Fitted case and doesn't have the issue. The back of that case is a fabric material. It seems to be any case that has reflective material may do it. Or maybe the opening for the flash just isn't big enough on mine, I dunno.
The problem is because of the fiber-optic nature of the cases. If the same piece of plastic is covering both the flash and the lens, then some of the light will bend through the plastic and create that blue haze over the lens (LED lights are, actually, blue).
If you look at the iPhone without a case on it, you'll notice that the lens for the camera is actually completely isolated from the rest of the glass by a metal ring, which keeps this flare from happening.
Consequently, the only solution is to have a case that does not cover lens, or, ideally, the lens or flash. Keep in mind that if you have a thicker case that is translucent, even if it doesn't cover the lens, the tapering around the lens can act as a ring flash, illuminating the camera lens and casting a blue flare over the lens as well.
So, the problem is with the type of case you're using, basically. If you're using just a clear back decal covering, you'll want to cut a hole out for the camera and maybe flash. If it's a more complicated case, well... I leave you to your own devices (though you'll likely void warranties of anything you take a razor or drill to!)
