Help! After 30 years of film photography and building up quite a lot of 4x6 comercially de3veloped photographs, I have made the leap into digital and love it. Being a Nikon freak as was my dad who got me into this obsession I went out a got a d-100. . I have numerous photos i would like to scan into photoshop elements and tweak them. I have scanned them but when i print them on my epson 925 they dont look as sharp as they should. Pixels resolution scanner dpi printer dpi is confusing. I am not a computer wiz. I need to know a step by step way to scan a 4x6 with enough quality that it can be enlarged to an 8x10 without losing definition or sharpness. any assistance would be greatlY apreciated.
Depending on the image, it takes up to 300 DPI in the original image to produce a print that appears sharp and detailed to the naked eye. So 8x10 would be a 2400x3000 image or 7.2 MP. With a good printer, such an image would be fantastic.
Lots of research shows that the best prints only have between 300-400 dpi of resolution that can be scanned. So if you scan at 300 DPI, you'll get just about all the detail you can get. Or at 400, you might get additional detail. However, that would give you a 1200x1600 (1.9 MP) or at best, 1600x2400 (3.8 MP). So printing at 8x10 would already be compromised.
Quality resizing and sharpening can improve the image, but you can't make something from nothing. Scans are usually a bit soft, so I suspect that if you experiment with sharpness, maybe scan at a bit higher resolution, you'll find a sweet spot. But the quality won't be up to 300 DPI ideal for the source image.
Better option is to scan the film if you can. Extremely time consuming process.
Don't have a step by step for you, but maybe a little background will help your cause.
Scan your 4x6 print at 600 ppi output resolution. You should see 'output resolution' in your scanner software when you're preparing to scan your image. This will enable you to convert the 4x6 to an 8x12 at 300 ppi in PS Elements.
With the scanned 4x6 open in Elements, go to Image->Image Size and make sure that the 'Constrain Proportions' box is checked and the 'Resample Image' box is unchecked. Type in 8 and 12 in the width/height boxes and the resolution should automatically change to 300 ppi.
You'll probably need to apply the Unsharp Mask filter to the 8x12 as scanned images tend to lose a bit of sharpness from the scanning process.

Thank you,I do apreciate it. Photography by itself has a lot of technobable and when you through computers in to the mix it quadruples. I never really liked film darkroom work but digital darkroom I can't get enough
