Deadlines can be a good reason to use jpg, but not the only reason. Raw + post processing in an image editor is just a tool, just like using jpg and in camera parameters. If I can get an image like this
or this
using in cam settings, then what advantage will raw give me? Well, I will be able to make the processing decisions after I click the shutter, but chances are, those decisions would result in the same final output. Now, let's say I am getting paid for the images (for the pottery, I am). Time is money, and face it, a raw workflow - no matter how fast you are are - takes more time. If you can't get the results using jpg, then use raw. But you'll have more time to work on more things if you're more efficient in areas where the quality difference won't matter. Those images are made under controlled lighting, won't be printed large - if at all printed - and are all basically the same setup save a reflector or gobo here and there. These were both shot in the same run with about 60 other items. After shooting, post work - which included a crop and/or resize along with some high pass sharpening - took about 10 minutes total. Now this picture
was shot in raw, and utilized many different post processing techniques. I spent about 2 hours total, over the course of a few days on it. I could have probably gotten close to it in jpg, but the flower might have died before I figured what settings would give me what I wanted. The right tool for the right person, with the right skills, for the right job. One is no better than the other, just more appropriate for the user or job.
