Free, in-app purchases
From x.photoscape.org
As well as a range of useful photo-fixing tools, Photoscape X offers a host of creative image processing options such as light leakage effects or dynamic zoom blur. You can combine adjustments as layered effects. Many of its tools are free but you need to pay to unlock its Pro features.
1 Creative effects
After launching the Edit in PhotoscapeX extension click on the Light icon. Here you’ll find a wide range of retro light leakage effects that make digital shots look like old film prints. Click to apply an effect and adjust its Amount slider.
2 Zoom blur
The Zoom Blur effect adds streaks of motion blur that mimic the effect produced when you rotate a DSLR’s lens during a long exposure. You can define the focal point of the blur and use a masking brush to preserve key details.
