Filters, light leaks, vignettes, and frames are named, e.g. "Retro 12" or "Light 2" instead of a real descriptions, which makes it hard to remember which ones you like best. I generally like the variety of light leaks, but the filters and frames are nothing special.
Sliders for brightness, contrast, saturation are hard to work with because their names are miniscule, and there is no "undo." Same for grain slider, except that I also cant see any effect from it. Bokeh effects are just fuzzy spots placed in front of your picture.
Saving a 3.9 MP picture with the "Original Size" setting resulted in a picture that was only 0.7 MP.
If you get this for free, and dont need full-size pictures, and for some reason dont want to download one of the many really good photo editors, this one will do an adequate job.
