Weird Film Scan Situation
" wrote in message . ..
Hi, I am mystified by the CD's I just got back from my photolab. I asked them to scan a roll of slide film at "medium resolution" (3000x2000 according to their literature) and also at "high resolution" (6000x4000) so I could see the difference. I got back 2 CD's. The one marked medium has two folders each with the same set of .jpg files about 3000x2000 pixels. Each is about 1Mbyte in size. This seems very small to me. The one marked high has one set of the same images, again 3000x2000 jpg files. Each is about 5Mbytes. This seems more reasonable for a high quality jpg with that number of pixels. The image pixel sizes are reported by Win Explorer and match those reported by Photoshop and Irfanview. So, first, I don't know what happened to my 6000x4000 scans. I'll have to ask the lab. But the weirdest part is that these were pictures of flowers (lupines) from several meters away, with lots of fine detail in the images. When I blow up the pics to 100% in PS, I see no difference except that the "hi res" ones look slightly less smooth. Both images look quite good at the fine detail level. I would expect that the "medium res" ones would have lots of artifacts due to the high compression that must have happened. How can 2 jpg files with the same pixel dimensions look the same if one is 5x bigger than the other on the disk? And is there some wonderful jpg compression that can squash a 3000x2000 raw scanned color image (18Mbytes or so I would think) into 1 Mbyte with no artifacts? And I thought I had a good handle on all this stuff... TIA Duncan Why are you asking that ****ing question in this forum? This is not the right place. Why don't you take your old fashioned film and ram it deep inside the depths of your honkey tonk culo of yours. You gringo. You have some really big elephant balls to post that **** here. And don't **** with Mexican Sigma owners. NORTE! NORTENO XIV!!! |
