Wrote up a little post on my Kickstarter project about using advanced iPhone settings to view film negatives on your phone. A handy tip from my friend Troy. Here’s an excerpt:
To set up this process, open Settings>General>Accessibility>Triple-Click Home on your iPhone and select “Invert Colors”. Now when you triple tap your home button, your screen turns into a “negative” image. Now all you need to do is open your camera and triple tap the home button to be able to view negatives on your iPhone.
