Still image - Disabling Auto White Balance etc.

[tierone]

Hi there!

I would like to present a mock-up of an iPhone app for a project and need some information that I was hoping some of you could give me.

Basically it all revolves around the ability to turn off the auto-white balance (and any other kind of auto adjustments) during taking a still image. I want to do this in order to take pictures that are as predictable as possible. For example, if I take a picture of a blue wall, I want the result to display the same color everytime without worrying that some auto feature screws it up.

I would very much appreciate, If someone knows the possibilities of the still-camera features of the iPhone (3G or 3GS doesn't matter) and could give me an answer to this. No need for complicated explanations. Yes/No is enough.

Thanks!

You're out of luck with the standard SDK. The only way to access the camera is with the UIImagePickerViewController class, and it doesn't give you access to anything related to the camera at the hardware level.

I have a similarish question:

How would you display the camera output (eg when you are aiming) in an app?

Thanks for your quick answer. I guess I will have to improvise and stretch the truth a bit when pitching my idea.

so howd that go for you?

have you looked info AVFoundation and accessing camera properties that way?

you can do so much more with it rather than just the standard UIImagePicker
