Photone app for iPhone and iPad

Create beautiful monochrome images from your photographs. In the darkroom, photographers toned their prints with sepia or salts of selenium, platinum or gold to get these effects. In Photone, you just touch the screen for an instant transformation.

When Photone first loads, it displays the color palette which you use to choose the toning color. You can touch this palette anywhere to see how it works: move your finger around the screen. Then pick the photograph you want to tone and choose the color you want. The more saturated colors at the edges of the screen shade to neutral gray in the middle.

Photone does not work like a color filter. Its effect is like a duotone print: the shadows stay black and the highlights stay white, with graduated shades of the chosen color in between. Relative lightness remains unchanged, so you can tone a toned photograph with a different color without any loss of quality.

On the tool bar:-
• Pick a photograph from the Camera Roll, Saved Photos, or the Photo Library.
• Save the toned photograph back to the Camera Roll or Saved Photos.
• Mail the toned photograph attached to an email.

The photograph you pick is displayed first in color. If you Save or Mail it without choosing a toning color, a black and white version will be saved or mailed.

Note that this app requires permission to access Location Services. This is only required because reading a photo in your library gives the app access to location metadata which may be present in the photo. Photone does not track your current location.
