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.
The app offers more frame styles to add around the border of your image.
You can apply a mirror effect to the image, allowing you to experiment with creating symmetrical images.
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.
Using the brush tool you can paint across the image, or use it to make small adjustments to touch up the image.
When taking a picture with the app, you can preview your next photo with the filter already applied. This means you can choose a filter that compliments the scene before you capture the image, rather than applying it later.
