It is compatible with a range of iOS devices such as iPhones, iPads and the iPod Touch.
There is a tablet-optimised version of the app available. This gives a much better user experience than using an app designed for a phone on a tablet.
This can be used to rotate the image for an interesting effect, or more commonly to correct the image if it is at a slight angle.
Adjusting the contrast affects the difference between light and dark areas of the image. You can fine tune it to meet your needs, such as increasing the contrast to make your subject stand out more.
If your photo is too bright or dark, you can adjust the brightness in order to get a well-balanced image.
Saturation refers to the intensity of colors. It is measured on a scale ranging from 0% (black and white) to 100% (pure colors) at a constant level of brightness. Images with high levels of saturation have vivid colors, while unsaturated images appear greyish.
With manual white balance you can choose the most accurate setting and avoid the green, blue or red hue which can occur in auto mode. You can also change the setting for artistic effect.
Using selective adjustment points, you can change the settings (such as saturation, brightness, etc.) of a particular part of the image. This is useful if you wish to edit certain areas without changing the whole photo - for instance, if you wish to increase the color intensity of an object in the image.
Filters allow you to apply effects to your image with one touch, usually with a range of effects such as retro films or sketches.
The app offers more frame styles to add around the border of your image.
You can add captions and titles to your photos.
Image sharpening tools emphasize the edges within an image. This can be applied to a blurred image to make it appear sharper and more detailed.
Using the brush tool you can paint across the image, or use it to make small adjustments to touch up the image.
You can tag your photos/videos at the specific location where you took them. This gives you another way to organise them, and also makes them more discoverable by other people.
You can order physical copies of your photos directly within the app, such as different size prints and photo books.
