A solid performer, with one minor flaw. – Filterloop Pro: Photo Editor Review

The developer has continually improved on this app. There are a nice set of free filters and textures, and more via IAPs. The app saves at full resolution of the original image (24mp tested on iPad Air and iPad Pro) when applying a filter, however if you then use any of the "Adjustments" like vignette, exposure, contrast, etc., the app lowers the image resolution to the device's graphics processor throttled resolution of 11.2mp with 4096 pixels on the long side. That's really too bad, a blemish on an otherwise stellar performer. Maybe the developer can up the game. I hate to lose image resolution.
