ELP5 Tone curve adjustment
Hello, I'm here !
Yes, tone curves are still there. They were in the E-PL1 it seems but only accessible via one of the simpler live controls. In E-PL2 it moved to also being on the Up button as mentioned. They are on E-PL5 of course but I've never bothered to play with them.
If mucking about with attempting to get "perfect" jpegs out of the camera, why not do what I do and set up for "acceptable" jpegs out of the camera and then always take RAW+jpeg so can use a decent RAW converter to later do better work on creating a decent jpeg from a shot that you like.
Less time fiddling with camera settings in the field means more time to see and take shots, fiddle later at home when time is available.
