Also, if you have any suggestions for features you'd like to see in the app then please let me know. I've implemented image processing filters for level shifting, vignette and applying a border and I'm using QtImageFilters for various convolution effects (sharpen, defocus, highlight, blur, etc.). Am I missing anything? Do you think it's a good idea to allow the user to edit the filters that will be applied or should I just provide presets? I look forward to hearing your suggestions! Thanks, Roy
