I was using Photoshop already, I had been using it for graphic arts stuff for probably 10 years already at that point, so Photoshop wasn't the issue, it was just my mentality of not wanting to use too much space on my memory cards unless absolutely necessary. I had already been editing jpgs and very comfortable with that.Simple and it works - I like the dark skies as a backdrop.
Right after I got my Canon D60 back in 2002 I attended a lecture sponsored by Epson with Vincent Versace as the speaker. He gave a demo of using Photoshop to manually blend layers to get better dynamic range out of an image. I got hooked immediately on the notion of using RAW to make different light in my photos with Canon's Digital Photo Professional and then feed them into Photoshop as layers since ACR and Lightroom didn't exist yet. I haven't shot in jpg mode ever since.
Back then while there was more dynamic range in a Raw image for sure, bracketing was an absolute must to get full dynamic range. So for that aspect since I would bracket and use layer masks in Photoshop, I wasn't really that hindered by shooting jpgs. It would mean a couple of extra images for bracketing. If a Raw image needed 3 images to bracket and blend, a jpg needed 5 images.
But obviously there was advantages to shooting raw, I just saved those advantages for the really special images. Once I got over the mental block of not worrying about file sizes and space they would use, then I finally switched to only shooting raw. And of course through the years, Raw images and their dynamic range has continued to grow and make the gap between Raw and jpg even more significant. Back in 2005, it was a small gap, but today, the gap is the size of the Grand Canyon.
