I always challenge people, who want to really learn photography, to pick one prime lens and shoot straight to JPEG for three months. Everything, one prime lens in JPEG. Do it!
I so totally disagree.
A lot of you seem to agree with sanj on this challenge by me. Maybe clarifying a bit will help, or maybe it won't help an ocean. Oh, well, here goes nothing ...
This is not about RAW vs JPEG. Full stop. Period.
This is about learning the art of photography, and one of the best ways of learning is to appreciate what you have at your disposal. The objective is to limit the student as much as possible (without resorting to film), so that the student can understand that something like post-processing is part of the whole, a cog in the machine; a whole that starts with the correct basically correct creation of the image.
Many people, in their infinite wisdom, view RAW and the camera as simply a means of acquiring data for processing with a computer. This, in my opinion, leads to GIGO (garbage in, garbage out).
And obviously, once you've progressed beyond this step in learning the art of photography, you don't need to ever shoot JPEG again.
However, what is pretty interesting, is how many of the "photographers" on CR are so violently opposed to the idea of going JPEG for a few months. Oh, well ...
