The description of Scene Sketcher
Starting from your device's camera, photo gallery or cloud accounts, photos are easily cropped, zoomed and panned into the proportions of your canvas. You can touch points to choose or modify colors to add to a custom palette for the photo. Using a wide range of gray-scale and blur settings, you can make simplified images to see the main value patterns.
Scene Sketcher has a unique touchscreen capability to toggle portions of an image between gray-scale and color based on the value at the point you touch. This feature helps simplify a scene into color groups of similar value. The palette is automatically filtered to show the colors you've chosen in selected value ranges.
The app also has a touchscreen measuring tool that emulates traditional arms-length sighting and measurement against a key landmark. You can use it to find proportional relationships between elements of a scene, or to get measurements in inches or centimeters to transfer to your canvas.
You can make high quality screen captures for studio reference at any point as you work with an image.
An in-app upgrade adds three additional features: Two 'palette views' simplify the colors and shapes of your photo to help you see the basic composition. A broad range of control is provided so you can vary the abstraction and color mode of each view. One view scans the photo for colors, the other makes a poster from the palette colors you've chosen. A group of 'layout' controls saves all the view settings of the photo you are working with, so you can pick up in another session and resume the view you were using, including its landmark. You can also use the layout to pan and zoom your current image, then snap it back to its saved composition.
