I learned most of my craft on film, and shot a lot of color slide film which was never edited and was developed to a single, standard gamma. Everything had to be done in-camera. Film was expensive and always finite. Today, I can shoot all I want and have wide control over gamma, saturation, and color palette, on every frame!
Editing from raw images is now verrrrry easy compared to how it was with the $499 Nikon Capture 1.0 app that could open and edit .NEF files 15 years ago. At that time raw files were new and difficult to open.
Today we have such high megapixel imaging that final image crop and aspect ratio are quite flexible. The 'never crop, print with a filed-out negative carrier and black knock-out borders around each image' line of bullspit now seems pretty dated.Ancient history. Like typewriters, and white-out,and pay phones, and music videos on MTV.
Editing? Not sure what, exactly, that word means, and to who or to whom. We need to keep in mind, there is photography and there is digital imaging, and these are not the same things, so some of the old rules and ideas no longer apply in the same ways, or at all.
It makes a lot of sense to realize that most of us left analog or silver-based "photography" behind, years ago, and we are now in the pioneering stages of digital imaging. There no longer exists a fixed, permanent image held in an emulsion, on a base of tin, glass,or cellulose,or on celluloid; no, we no longer write with light in a permanent form, but instead we push pixels around, into multiple arrangements. We can develop, and print, in broad daylight, without caustic chemicals. It's time to leave outdated ideas behind, and focus on new realities, and this is especially true for those who are just starting to find their way. Silver-based photographs are in a permanent, fixed, tangible, physical form: digital images are in binary data.
