Most people use the two term interchangably, and to an extent they can be. A pixel contains 3 colors (it is a triad unit) RGB even in a true grayscale image whereas dpi as pertains to printing is one dot of one color. In most programs (well at least photoshop) it is actually listed as PPI or pixels per inch. Scan at 300 ppi and scale it to the largest size you think you may print it at. So - your scanning resolution should be guided by the file dimensions you need for your purpose - for screen display or for printing.Dude, too much math. So - your scanning resolution should be guided by the file dimensions you need for your purpose - for screen display or for printing. Then bring that into Lightroom or Photoshop for cropping, levels etc. That lets me see if I want to make a print, in which case I go back and take a best-quality scan, maximum resolution, maximum-bit colour saved as TIFF. (600 dpi x 2.25 inches) x (600 dpi x 2.25 inches) gives me a file 1350 x 1350 pixels, which fills the screen on my monitor. I generally scan initially at 600 dpi just to give me something to look at on the screen. But if you want quality that is the only way to go. The file sizes will be huge, especially with colour negs and saving in TIFF format. If you need to print bigger, scan at any resolution up to the scanner's maximum optical resolution (ie true scanning resolution with no interpolation by the scanner software).

This is the reason for high-res scanning capability - to capture all the detail in the neg and to make a large file size (in pixel dimensions).Ī file 2700 x 2700 pixels in dimension can print at 9 inches square at 300 dpi, with 1 pixel per dot on the paper, and no need for further interpolation by the software to produce extra pixels. And more importantly, this will capture a lot more fine detail from the negative compared with scanning at 300dpi. To turn 2.25 x 2.25 inches of negative into 2400 x 2400 pixels, you need to scan at more than 300 dpi: you need 2400 / 2.25 = 1067 dpi.įor moderate enlargements, scan at 1200 dpi - that will give you a file 2700 x 2700 pixels in size. Now, you are starting with a negative at 6圆 (cm) or 2 1/4 inches square. With a 6圆 negative you'll probably print at 8 x 8 inches or 2400 x 2400 pixels image size (assuming you don't crop). To print an 8x10 at 300 dpi you need an image file that is (8x300) x (10x300) pixels or 2400 x 3000 pixels. DPI means dots per inch, and each dot needs a pixel. Let's say you want to print an 8 x 10 print that's 8 inches by 10 inches. I will probably just scan the image 'as is' and manipulate the image produced in Photoshop.Ĭan I just toss in a few ideas here about the issue of scanning resolution and printing resolution? Nesster referred to 300dpi as printing resolution - it is true that many high quality printers will print at 300dpi, but that does not mean you scan at 300dpi. I see that the digital Ice does soften the image a bit, too not always an effect I desire to achieve. I need to experiment with both to compare the results. I also have Vuescan 8.4.47 which doesn't seem to be as sophisticated or complex as the Epson software. The software appears to be the same that came with my older Model 3490. However, for printing shouldn't I be scanning at a much higher dpi quotient? what software does Epson package with the V500?For web viewing I agree that 300 dpi is more than adequate. It occurs to me, I'm assuming your software is Epson.
Oh don't be so hasty, after all the site had a major melt down. what software does Epson package with the V500?
The artifacts include a general softening of the image, and sometimes streaky skies. The ICE stuff is a mixed blessing: on the one hand it is effective, on the other sometimes the artifacts it produces are too much for a given photo. If your software allows different settings or curves, try them out. In post processing you can always re-size to what you need.Īuto balance & auto exposure sometimes is close enough, sometimes needs tweaking. At 300, which is a photo print quality scan, it's as though you're scanning a print the size of the negative. LOL so I emphatize with you there.įirst, you should scan at >300 DPI, I found 600, 800, 1200 were decent compromises between too large and time consuming vs. I still don't know how a lot of stuff works, it just does. Here are some tips with the Epson software - I've since switched over to VueScan which is better but is also confusing as all hell.
