SRB Griturn are the masters of adapters. They list dozens on their website and can make many that aren't listed. Most lenses can be used on Pentax bodies, but I can't speak for other marques of body in the same detail.

Think of layers as a pile of acetates, just like we used on overhead projectors in lecture theatres. Each layer can be removed or adjusted as required, and when we've finished they can all be combined at the end with Flatten Image. Adding or removing a layer doesn't mess with the pixels of the original image, so is a much better way of doing many adjustments without destroying or degradind the original.

Where I disagree with you Nigel is that I think we are photographers, not computer program users. Just in the same way as we were once photographers and not darkroom users. Yes, we use computer programs just as we used darkrooms, but that wasn't and isn't the primary focus.

Of course it's possible that someone could indeed be more interested in the computer than the photography, or making darkroom prints as opposed to the photography, but the nomenclature is still the same and needs to be understood.

and many unintuitive methods and terms ... 'burning, dodging, unsharp mask?'
For anyone who has ever done any film darkroom work, these are very intuitive terms. Burning is giving more light to an area to make it darker, dodging is holding back light to make an area lighter, unsharp mask is a film process for giving an illusion of sharpness. The earliest mention of this last term that I have found is in the early 1930s, but it may predate that.

I've asked about the number of views indicator. It was quite nice to see how popular a particular thread was.

You can click on images for a bigger view. The Gallery is now particularly nice in this respect.

What a fantastic opprortunity. I'd buy one like a shot, but already have the 43mm so can't justify it just for the sake of it. It's a terrific optical design though and delivers stunning results.
