![]() ![]() But then again, if the optimum height is where the standard negative holder lies, then why waste money on an expensive, adjustable negative holder?Ĭlick to expand.I have holders for 120 and 135 but when it comes to 4x5 the v600 doesn't have a holder for that. You may need to buy an adjustable height negative holder if the optimum height isn't where the standard negative holder rests. That will also help determine the height of the negative holder you need. If the dime laying flat on the glass is sharpest, then don't waste money on a negative holder. Whichever dime is sharpest will determine the height at which you should be scanning. Zoom in on the scan, and determine which dime is sharpest. That will give you several different heights to experiment with at once. Stack them so when you scan them, the scanner can pick up parts of each dime. Take a stack of dimes and lay them on the glass of your scanner. For me, a negative holder was a waste of time and money. I found this out on my Epson 4990 when I bought a negative holder and noticed my scans weren't as sharp as before. Not all scanners work best with a negative holder. It is probably easier to work with a scanned image where the film is at the right height, but it is difficult to predict what that height will be on your scanner,īefore you go spending money on a negative holder, measure the optimum focal distance for your scanner. Ironically, if you want a scanned pinhole image to look sharp, it works best if you first throw away a lot of the detail by resizing it down, and then add the sharpness artificially. Unsharp masking techniques and control of contrast are the most common techniques - both when working optically and when working with a scanned image. Whether you print optically or scan, if you want the image to appear "sharp", you need to add that sharpness artificially. ![]() Even if the pinhole image is full of detail and tonality, it won't normally appear "sharp" This low level of acutance is simply a natural consequence of how pinholes work. And acutance is probably the most important component of the very subjective phenomenon that we refer to as "sharpness".
