iPhone 4 camera’s yellow tint: cause and workaround
Anyone who has tried to take a photo in very low light conditions using the iPhone 4’s LED flash is familiar with this issue: the photos come out with a yellow tint.
The Apple discussion forums are abuzz with posts on the issue, with most users suspecting a white balance problem.
Yesterday, the excellent Camera+ app received an update allowing, amongst other things, for the LED to be left on continuously when taking photos. The results? Perfectly white balanced images, without a trace of yellow.
So what gives? Well, I have a theory: the issue with the LED is not one of white balance, but of timing. In very low light situations, the iPhone 4’s camera shutter needs to remain open for longer in order to capture the shot. For some reason however, the LED flash appears to turn off just before the shutter closes, possibly casting a yellow tint over the image as it cools down - or in any case throwing the camera’s white balance out of whack.
As Camera+ demonstrates, if the LED flash is kept on before, during and after the photo is taken, the camera captures a perfect image.
What this suggests is that Apple should be able to fix the problem in software, simply by keeping the flash on just a fraction of a second longer. Until then, Camera+’s solution, while a potential battery killer, provides a neat little workaround for shooting in low light situations.
