OMG! My maxis iPhone 4 Camera Gives a Bluish or Greenish Spot!

Taken in the workplace, under fluorescent lighting
You start using your maxis iPhone 4 camera. To your horror, your photo has a big blue or green spot smacked right in the middle.

Does your photo look like this?

Ok. Don't panic!

It seems that this is perfectly normal if the photos are taken under fluorescent lighting. Many cameras, including iPhone's has issue with white balance.

Turramurra quotes: "I shoot with a Canon camera that is worth over $6000 & in certain circumstances even it can't get the white balance right when set to auto.



A blue-green cast is typical when shot under fluoro lights, a yellow cast is typical when shot under tungsten (regular) lights." 

Givmeabreak said "All cameras have a problem with fluorescent lighting. Especially cameras that don't let you control white balance and shutter speed. The lighting is changing 120 times per second (twice per cycle). In low light the shutter speed is probably below 120. This will cause uneven lighting in the image.

With a mechanical shutter you you will see a bar or half an image affected, even on a professional camera like my Canon 5D2 the result is the same. With an iPhone that has an electronic shutter the result is more unpredictable. You see a blob in the image. There is no quick fix. Change the lighting by using the flash, turning on more incandescent light etc. Post processing can help with white balance issues."
 
WSL, a photo blogger, said: "I didn't have high expectations from a camera phone. I use my Lumix"

She has the greatest quote of all!

I didn't notice this until I read about it. Now the spots are glaring up at me.

Outdoors photos are picture perfect:



If it bothers you, there's an app to fix those photos :)
