Could you post development time and quantity of potassium iodide. Thanks.

Love the portrait. Great expressions.

Edit: Think I found the usual recommendation. 50ml of 0.001% potassium iodide solution in Part A. Correct?

Wonderful portrait. Looking at his scalp, where it 'borders' the background, it looks almost too sharp, like an unsharp mask, yet the background and its grain isn't affected. Or like a super imposition.
Very interesting, and a good way to view the adjacency effects. I have a similar situation print that you can find here: http://www.apug.org/gallery/showphoto.php?photo=29226&ppuser=395
It shows the same glow around the edge of her right side. Yet it is Neopan 1600 in Ilfotec DD-X. Hardly an acutance developer. What's going on there, you think? Not adjacency effect, methinks.

It's a great image, but hard to say what is due to the choice of film and developer, and what is due to the lighting, lens, aperture, subject distance, and distance from the subject to the background.

Thomas, I think the appearance of the scalp is mainly due to the limb effect, which may be accentuated by other factors, but it's hard to tell without a comparison shot.

Tis a very fine portrait, edge effects or not. Great lighting, expressions and very well executed all round.

I think David makes a strong point though, in that there are so many links in the chain which contribute to the final result and it takes all of these to come together in the right proportions rather than just pinning too much on the fact that 0.0000000123gms of whatever is added to something somewhere.

Sorry if I sound too cynical ...! It is a beautiful photo

Thanks for posting the image Dennis, it's obviously pertinent to the current Acutance thread, and is a good example of the side effects of using Acutance developers.

Nice image regardless,
Ian

Thanks for the info Dennis. I had noticed the edges at the back of the shirt and pants. But not knowing your workflow, it's hard to know if the edge enhancement is jpg sharpening or the film. I've posted a shot here that was criticized for being over sharpened after the scan, when it wasn't at all.
