You can add an HDR-style effect to the image, whereby the darker areas appear brighter and the bright areas appear darker - giving your image more dynamic range. This gives you an image which looks more akin to how the human eye sees it, rather than a camera.
Filters allow you to apply effects to your image with one touch, usually with a range of effects such as retro films or sketches.
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.
Tilt shift is a technique which can be used to achieve the “diorama” effect, whereby you can make normal images look as if they were taken of small models. It works by applying a blur to parts of the image which simulates a shallower depth of field, even on objects far away.
You can add captions and titles to your photos.
The app offers more crop sizes (such as 4:3, 1:1, 4:5), giving you more versatility when editing your images.
