Could this be causing the "Green blob" with the iPhone4's camera lens?

    I've been doing some thinking about that GreenBlob affect that's plagued some iPhone 4's.

    Could the lens be sensitive to the light spectrum that is CFL lighting (and light from LCD screens, maybe?!) that it would cause a type of 'burn' on the lens and thus creating the error?

    I wouldn't ask anyone to do this, but I'm just wondering. If you have 2 iPhone 4's and one is experiencing the GreenBlob affect and the other is not. Take the none affected iPhone and take a picture of a CFL light, like in some office buildings, hallways... (think about the ceiling lifts at a Wal-Mart store) and see if this would recreate the issue.

    I have a hunch that it might.

    Picture links are broken. But, in though the green blob was only in some kind of light, can't remember what it was, fluorescent light?

    I guess that would depend maybe.

    I've seen some posts with before and after photos that showed a photo of one place, and no green blob, and then later on in the same lighting conditions as previously used before, the blob was apparent... So I don't know. It's all funny business to me..


    Oh and for some crazy reason, I haven't figured out how to upload screenshots to imageshack so I can post them on here..

    My iPhone4 was actually pretty fine until once I took a photo at our office toilet (don't ask) with flash. After this shot I had the green blob issue for a few weeks but it resolved itself somehow, I didn't realize when it happened but right now my iPhone4 photos are fine without any green blob. The room where I took that photo which created the green blob has bright white walls and I think neon lights.

    It's been explained many times. It's the relationship between the flickering fluorescent lights and the slow electronic shutter. Basically the lighting and white balance are not consistent during the exposure.

    Similar problems can be shown on any camera. With a more sophisticated camera you can avoid the problem with a higher shutter speed, change in ISO, lighting etc. With a simple camera you can only change the lighting, location etc.

    Change the lighting or the location. Use incandescent lighting, turn on the flash, open the windows to let the light in etc. There are a lot of solutions.

    Incandescent lighting is not fixing the issue with my phone, nor is the flash. The flash is over exposing all my photos.

    I have a replacement coming in the mail, so I'm hoping it doesn't have the same issue.

    Is everyone experiencing this or just a select few?

    Isn't it just the anti-glare coating on camera? I looked at my iPod nano in the dark with glasses and there was a faint green spot! :D (Not kidding)

    if you search "green blob" on MRoogle you'll see that people are saying its probably your lighting.
