Before they invented pixels much of the stuff that we do in post production happened to the image as it was taken. There used to be a vignette you could apply 'on camera', there were wonderful things that you could do using a softar filter. There also was attention to detail. Details of composition, lighting, expression and, dare I use the word, posing. We now shoot a ridiculous number of frames as we become more opportunist and somehow more reckless. Certainly from this reckless/prolific behavior we get some true gems, but we often create more work than is necessary. I just wanted to give a plug to doing it right in camera over fixing it in post production. Know your light, know your composition, and start with well exposed images. I am aware of a move to learning more about the craft of photography, and I fully support that as the new era of photography ... another case of the latest 'new thing' being the old thing but better. Why does it matter? It matters because it costs us ... It costs us in time and quality to deal with these things in post production ...  Join the revolution! The revolution for photographs shot right in the first instance. Cheers, Johannes
