When I decided to create the Picture to People online branch, my intention concerning photo manipulation was release my effects that are hard to get in most of (even paid) graphic softwares. They can be very useful even for professional designers, mainly the effect groups: Cartoonization, Drawing, Mosaic, Painting, Pencil and Sketch.
Now the site is online and I get users feedback everyday. A lot of them have been asking for simple traditional photo editing tools, like Reduction, Grayscale, Contrast, Crop, Flip, etc. I'm working to meet their wishes and needs, so the number of this kind of utility is increasing fast in the site.
Beside this, Picture to People site has getting a good amount of photo effects very useful for the digital photo user with average skills, like Color Improvement, Dithering, Liquify, Makeup, Pastel and so.
Anyway, the roll of photo, text or pattern effects will keep increasing fast.
