Let's say we have a medium format negative which after cropping is 2x2 inches. If we scan at 900 ppi, we can make a print which Make a print which is twice the size of the original. If we scan at 300 ppi (pixels per inch) we can make a print at the same size as the original. Standard print quality is therefore referred to in the USA as a '300 line screen', namely 300 dpi (dots per inch). There are roughly 25mm in an inch, so 25 x 12 dots = 300 dots in an inch. We choose the scanning resolution, depending on how much we plan to enlarge theДЄt typical viewing distance, people with normal visionД¬an discern roughy 6 line pairs/mm, or 12 dots/mm. I use blue painter's tape which comes off easily. When we use the Film Area Guide the scannerДЇocuses at the level of the glass. If we place the film emulsion-side down, Newton's ringsДЄre less likely to appear: this varies with choice of film. The glass and use the EPSON 'Film Area Guide'. If you don't need the highest resolution from the scanner, another option is to tape the film directly on For Better Scanning's comparison samples, click Sample of how the BetterScanning holder improves focus over EPSON's holders, see my before and after With either EPSON or BetterScanning holders, the scanner automatically sets focus to a few millimetersДЄbove the glass, but BetterScanning holders are adjustable so you can find best focus. To avoid these problems we can use a holder from BetterScanning. However, EPSON film holders crop the image and being shiny, they cast reflections onto the edges of the Newton's Rings: concentric lines caused by interference. Because the film sits above the glass, they also prevent It's not the printers which limit us, but rather the consumer-grade driverДЇilm Holders: Flatness, Focus and Newton's RingsД®PSON film holders do a good job of keeping

To edit our images, because banding is introduced as soon as we start making corrections in 8-bitДЄlso note that some printer software like Quadtone RIP allows us to print on EPSON That approach only makes sense if we're never going Only, there's no need to scan at higher bit depth. Some writers suggest that because consumer-grade printers and monitors are currently limited to 8-bit In color, this is really 48-bit mode, since each of the Red, Green and Blue channels gets 16 Even if we lose half of them, we still end up with a smooth It's much better to work in 16-bit mode if we can. With 8-bit color images, we can quickly get banding in each of the 3 Have that unnatural 'digitized' look, with gaps in the tonal scale. By the time we're done, some of our photos may We convert to JPG format, we may lose even more shades. When we open an 8-bit grayscale image for editing, we start out with onlyДў56 possible shades to work with and we proceed to lose data with each adjustment. Internet, we can always make a JPG file later (8-bit only) but our working file is in PSD format, at The file is smaller than the original TIFF but no quality is lost. Depending on our choice of matting and frame, we may decide to adjust the tones ofДЇinally, we save the file in the Photoshop PSD format, which uses lossless compression. We can do the same thing in GIMP with the Colorize tool.ДЄgainst a white background, the image feels different than when against the black background of the To tone the image in Photoshop withДЄ warm but subtle color, we can apply a non-destructive Color Fill or Photo FilterДЄccording to taste. In our editing tool (Photoshop) the image looks pleasing and natural. And don't sharpen when scanning, for the same reason. Never sharpen the original master file, since sharpening is a destructive We can make smaller versions for printing or displaying on the web, but It's easiest if we scan at the highest resolution we'll ever need. Scan at High Resolution: Downsize and Sharpen Last

To bypass all tonal corrections, see How to Minimize All Tonal Adjustments below. Perhaps EPSON considers these as normal values: this is not a Practice we should use whatever Gamma value makes the image look best. Should give us a 'linear' scan with no disproportionate contrast curve applied but in actual White tones, or pure black.) The right slider is actually past the end of the histogram.ДЇinally, we can adjust the Gamma setting back to normal, namely 1.0. Photographs are not required to contain pure Show the high values naturally, with no clipping or unnatural loss of texture. The right-side setting is light enough to We haveДЄdjusted the Input settings so that the dark values on the left side, are just darkД®nough to render the clear film edge as black - but no darker. We have corrected the default Output settings. Correct the EPSON Histogram Before Scanning
