Questions
In which order are the changes made?
Brightness first, then contrast, then saturation, with the same formulas as the Pillow imaging library, so the result matches what other software gives for the same numbers.
Why do bright parts turn pure white?
Making a picture much brighter pushes light colors past white, and the detail in them is lost. Lower the brightness, or raise it less and use contrast instead.
Can I do many pictures at once?
Yes. Drop as many as you like. Each gets the same settings, and you can download them all as one ZIP file.
Are my pictures uploaded anywhere?
No. The effect is worked out on your device, in your browser. The pictures are not sent to a server.
