^that's false, I recently found out that Nokia Camera can delete photos direct from app.
Nokia is not a third party developer (like myself and the rest of us indie devs), they were a second party, and are now a first party
I really hope they can relax their policies with regards to camera button launch of apps as well as allowing third party apps to delete photos. When WP8 was first announced, the Lenses API as well as the rest of the Camera API sounded stuff out of a mobile photographer's fantasy. We were promised quick and easy access to any camera app, as well as the first mobile platform to offer a manual focus API. Windows Phone was poised to become *the* premier mobile photography platform, but even with the best hardware on the planet they failed because of insufficient access to, or complete lack of crucial APIs (can't delete photos, can't do separate focus / exposure adjustments, the Lenses menu is
cumbersome at best, total lack of an API to save videos, etc).
I really hope 8.1 fixes this.
