How I like to edit images
I've learned from years of picture editing that even though nearly every digital file might look OK on the camera's LCD screen, they are often a bit lackluster once viewed on a high res computer monitor. This could be because the original lighting was poor, or because your computer screen isn't calibrated. But it's most likely because, being a machine, the camera does not record colour or contrast in the same way as the human eye does. This was especially true of early cameras, but now it's safe to say that the software that converts light into a usable electronic file in our camera is considerably more sophisticated, thus produces far more accurate results - which in turn requires less editing by the photographer. It's important to know that a JPEG file has already been processed by the camera software but a RAW file has not - it's up to you, the photographer, to make it look better!
