Litrato is an app for editing photos and saving those changes to the gallery. Filters and effects:

14 presets to quickly apply a filter (without any parameters). Transformations such as rotation, crop, flip... Essentials tools such as luminosity, contrast, gamma, saturation... More advanced filters that use convolution or blending two or more images. Almost all filters are using RenderScript, which accelerates the calculations.

User interface:

The UI is simple and intuitive, with menus, separate interfaces, and the preview of each filter. Dark and light theme. Zoom and scroll: it is possible to zoom on the image using two fingers or with a double tap, and then move around with one finger.

Tools:

“Color Picker”, a tool to select a hue directly from the image. "History" gives the user the ability to revert to any prior state of the image. A setting menu where the user can tweak some parameters. Those values are saved on the phone. An menu to view most EXIF values of the image, such as the ISO, f-number or where the photo was taken. Ability to only apply a filter to a part of the image. This "mask" is drawn by the user using its finger.

Load and save:

Take or select an image: images can be obtained from the gallery, or directly from the camera. It is possible to save the image in its original resolution, and have a smaller resolution while using the app.
