If a developed area and an undeveloped area are located side by side the edge of the developed area gets extra density due to the increased developer activity along the edge - the theory being the developer in the undeveloped area helps replenish the spent developer working locally in the developed part. You need to be careful at taking American adverts at face value - they don't have an advertising standard requiring adverts to be truthful - they can claim anything they like. Martin |

Same when I lived in America, many moons ago, You could never believe in what they the add, Even the American's never believed in the Adds, and For some reason I had a senior moment when replying and could not remember acutance, although I have used acutance developer's a lot over the last however many years, what I should have said is they were talking about Rodinal type developers, in which the edge effect, like any acutance developer gives the appearance that the negative is sharper than normal, although they do say you should mot use these with fast film and I always use fast film,
Keep safe Richard

1-50. I do remember for payment I got £75 and a box full of Kodak colour film The photographs in FP4 were quite grainy (also due to the edge effect) and the subject was electricity pylons and cables against a deep blue sky which emphasised the very fine, clear line between the dark and light tones - very similar to the effect that you get with the unsharp mask with Adobe The edge effect is also the reason unless you adore grain it should not be used to develop films of 200 iso or greater. If you think that may be excessive I tried it once with Kodak High Speed infra red. It was like a pebbledash wall. It almost had physical texture. |

And I don't know if it was applied for text submissions, but I remember when AP magazine started giving ONE 35mm colour film for pictures submitted and then this became NOTHING and yet people still sent in work. The lure of wanting ones work to be seen in print was the force behind that I imagine. When I next visit a W H Smiths, I'll have a quick browse of the mags, but especially AP, and see what the ruling is now. I wouldn't be surprised if you had to PAY THEM when submitting stuff now!
