How picky is the ATF about the pictures you submit with form 4?
I didn't have a white wall handy so I used an app the removes the background and replaces it with a white background, but on the state dept. website under passport photos it mentions no digitally altered photos. Does this apply to the passport size photos submitted to the ATF?
It already takes long enough to get stamp back and I sure don't want to delay it any further.
