Camera on the fly filter

Very interesting. I am amazed by the fact of how easy it is to do complex things in other languages, but so difficult to do simple things in other languages. I mean, creating buttons, sliders, windows … I am studying soda, seems the right solution. But still regarding the camera question. Is it possible to override the standard photo and movie buttons for my own?

You mean the buttons in the bottom left of the screen? No you can’t change their appearance or performance. You can hide them and then, for the screenshot button at least, implement something similar.
