2 Exif files in one image!

[abhishek]

Hi folks,

I wrote some code to add exif data in pictures taken by the iPhone cam.

I set the iPhone's exif value to null(in CameraViewController) hoping that iPhone itself would not insert any exif data.
After that, I enter my custom exif data.

However, when I view the file in hex, iPhone has actually entered some data itself, and then mine, thereby duplicating the exif info.

There are two exif tags!(sadly, mine is the 2nd one)

How do I force iPhone into not writing it's own exif data into the image file after a pic has been captured?

All help is greatly appreciated.
