Haven't tried the second link yet Martyn - but the first one is superb - answered a lot of queries I had about Camera Raw - I owe you a drink!! Thanks a million!!

i know a little Angie, ask the questions and will answer what i know if i am able and no doubt others will contribute also

At the moment Martyn, having watched a couple of those videos, I will be trying them out - but only when I have finished processing the photos from Venice (of which there were around 300) - about 50 to go!!

Some good stuff in there MArtyn...

The most basic thing about Camera Raw is if set up properly its editing in 16 bit files which means it is lossless. I do all my editing apart from extra sharpening and noise reduction in Camera Raw and only convert the files mode to 8 bit if i run special filter or have finished processing and intend to change the image to jpeg for end use.
