<p>[QUOTE="dougsmit, post: 2461819, member: 19463"]I do not know what TIF's requirements will be but standard 'wisdom' has been requiring 300 pixels per inch meaning a 4x6 print (the small size) would be best made from a file 1200x1800 or larger. I regularly push that and use my standard 1080x1620 reduced images and am satisfied with the results. Each coin on the tie will not be 4" across so I'd guess the minimum would be closer to 600 across which is what ancient coin guru's last batch measure. The camera I use most is 5,616 × 3,744 pixels maximum so all images I show are reductions. Most of us that have cameras have the same situation and have reduced the images we show here. The point is that once an image is reduced, it can not be expanded back to the original quality. The worst problem is the fact that no number of pixels will save an out of focus or camera motion image. 3000 pixels of bad focus can not be reduced to 300 sharp pixels (although I would think that someone should be working on that routine). Most cameras apply sharpening routines to the RAW images which make things worse in some cases by sharpening the wrong thing. </p><p><br /></p><p>I'm more concerned by the bad lighting or color problems in some of the images. Such images can be improved but the repairs will show when put side by side with images of the quality we see from TIF, Ancient Joe and some of our other imagers with great coins and camera skills. The worst part will be the coins themselves. The best possible picture of most of my coins will show all their ugly details to the worst degree possible.[/QUOTE]</p><p><br /></p>
