The canon creative filters in models such as the 600d are cool but they are so simple I usually don't bother with them. It would really be cool if magic lantern could somehow incorporate new filters that could be used in live view and film mode or if it could just give users more tweakability over the existing creative filters. The toy filter is kind of like instagram, but its not as capable as instagram, however I have a feeling that it could be with some tweaks. Also the toy filter is said to miniaturize things, it has never really worked for me but it would be great if it worked better and if you could use it in film mode! I have no idea if any of this is possible but it could be alot of fun to have more in camera effect power that saved time in post processing. Another idea I had was to incorporate color filters, alot of them at that, like the 85b warming filter for warming up images with flash, an opacity function with color filters would be great. Im not sure if all of this would work but I would happily store some extra effects on my card if it gave me the capabilities to do some serious image tweaking that I didn't have to mess with later in photoshop. And of course in the ideal setting these tweaked images would be saved as a copy of the original just like the main cannon function allows. Once again, I have no idea if this is possible but thanks for listening!
