Hi, One month ago I've purchased Camera JB+ app. There are so many settings which I don't understand, like... fx quality 1:1, 1:4 and 1:16 - which one is best quality? Many other functions/settings I just don't understand, like HDR etc. Is there any help page with an explanation on all those? I googled, but couldn't find one. Besides, is there a possibility to make a shortcut from a locked screeen directly to the camera? It's because I use the camera pretty often, and don't want to unlock the phone and press the camera icon each time I want to take a picture.
