Thanks for taking the time to write all that Rob, Not the why, but the how. I am interested in the why but I don't have time for it just now. I appreciate that you maybe don't have the time to write pages on RAW in theory and practice, however if you did you would be benefiting at least a hundred people (maybe the thousands to come!) seeking knowledge. And maybe this could be saved in a technical archive away from the forum (hint hint Attila! wiki! Smile )so when inevitably someone else pops there head in and asks the same question you can point he/she to the relevant page.

Actually, I have been trying the jpg straight out of the camera again and I have been getting some pretty good images, and a far better hit rate than shooting RAW with an MF lens. I do have a rudimentary understanding colour spaces and bitrates but I need to get my software to the right presets!

I will take a look at rawshooter, thanks for the suggestion


Good to hear some of that Bob.
I believe you will get there. I would not write such information because I admit I don't know enough. I have been doing photoshop for over ten years almost everyday, inc a lot of commercial retouching restoration, as well as my camera work. I have also been fortunate enough for many years to be able to follow images right through to the printing presses and see how those boys work. So I saw digital workflow come in before we even had a PS digital camera. I wonder how many 'Film purists' realise that virtually everything printed since the beginning of eighties has been digitised. I might add the Printing boys always said film and prints were the weak link in their own high standard of work. Which is why they had to spend silly money on drum scanners. A scanner that costs 10 times or more than the photo equipment used to take the photo and more than some of the printing plant! Just to produce a computer file good enough to match the quality of the rest of the workflow.
My answer to any reference is still the same Luminous Landscape. I send everybody to Luminous landscape. The stuff on there is what you want. There is an 'Understanding series' on most topics and
tutorials on many subjects. Workflow, RAW, Bit rate, Colour etc etc is all dealt with. The site is the best on the internet, nothing compares to it. Some goes well above me but there is also plenty that starts at the beginning. there is also plenty of creative theory stuff that is great.
Sometimes a jump backwards to camera JPEG can put you back on the right track. I have done it myself a few times and still have no real objections to shooting a few JPEGS when I need the camera to speed up. Used it today to do a flying Heron if I hadn't the camera would have froze after three shots but JPEG will shoot till the card fills. now I just have to be extra carefull picking the frames and applying any adjustments.
