The people at iSpazio are showing some interesting line code that one of their viewers found in the iOS 4.3 beta. It looks like Apple is preparing to release some sort of photo filtering functionality for the native camera app. like Photo Booth.

The picture above isn’t very clear, but there seems to be a reference to a compressor view, X-ray mode and a couple of others. Knowing how popular photo filters are lately, it’s clear there is demand for such a feature. Will Apple bring something new to the table, or just add it as a gimmick? I don’t know, but it’s very interesting nonetheless.
