What do you call "huge"? When printing maps from Ordinance Survey vector files which I may look at with a 10x loupe, I use my 2100 at 1,440 ppi at 330mm * 0.5m A high res image may not look good or sharp... to achieve apparent sharpness you must reproduce (some) detail with relatively little "noise". (Noise in this context is anything not in the subject, i.e. film grain, pixilation, distortion, etc.) CoC or Circle of Confusion is often quoted, but, when you want to resolve subject detail, the DoC, Disc of confusion or size of subject detail you can resolve is what is important: can you resolve the texture of the blades of grass on the lawn, the leaves on the trees, or the pattern of the bricks on the wall? I a month or two, when the new house is sorted, when I get the time, I will manipulate the Merklinger formulae to calculate the disc of confusion for any point on the subject for any setting of a monorail. I envisage putting the data into a spread sheet and using it to colour each cell so you get a colour image telling you what size of subject detail you can resolve where with what setting. =============================================================== GO TO http://www.prodig.org for ~ GUIDELINES ~ un/SUBSCRIBING ~ ITEMS for SALE
