Use your finger as a brush to "paint" sections of your image black and white, or to bring back the original color. Zooming in and out using the two-finger pinching gesture allows you to work on details with pixel-accuracy. Features: - Short tutorial videos explain the use of all features and will have you editing your images in minutes. - Choose photos to edit from your iPhone photo library or from Dropbox or Flickr. - Share your edited images on Twitter or Flickr. Email them, or save them to your Dropbox. - Save multiple sessions to resume your work later. - Undo any number of accidental brush strokes. - An alternative view mode highlights the regions that will remain in color with a red tint. This makes it easier to see and adjust the boundaries between color and black & white regions. - Choose from 4 different brushes (hard or soft edged, opaque or transparent) and adjust the brush size. - Hide the toolbars in full screen mode.
