With my E-30, editing images can be done for both RAW and JPEG formats. The plethora of control also enable multitudes of possibilities. Take for example, the E-30 has an added control for multiple layers. I have not done this, but knowing I can do this function in-camera is just great!
For this example, I added Auto Gradation and upped the maximum Saturation twice. I chose to process the JPEG instead of converting from RAW. Typically because I did not see much advantage of the RAW for this image.
