![]() Right now, there's just way too many unaccounted-for variables and not enough standardization (in hardware or software). At best, a scanner can give you 'relative' color (you need to have a similarly scanned 'known'), but not the 'actual' color. Use the same scanner at the same settings for all your stamps, and you have pretty good information for an insurance adjuster should anything ever happen to your stamps.īut if you're scanning to determine color variety, I don't think it can be done. If you're scanning to keep a record of what you have, great. Vuescan is awesome in that it re-interprets your old scanner driver so it'll keep making the same quality scans no matter how much Windows or Apple 'adjust' their operating systems, but the same images will still be different from monitor to monitor. Right now, in the end, the scanning process you use depends on why you're doing it. Focus is almost certainly both a hardware and software problem. ![]() Both images, however, lost resolution in the downscaling through software interpretation, and again in the format switch (I saved the converted images at the default compression - read that as 'whatever resolution loss the program decided was good'). The first (old) scanner has a 600dpi optical limit (interpolated up to 1200), so that one should appear much more out of focus than the other (4800 x 9600 optical). pngs so they wouldn't be absurdly large files for the post. tiffs, then downscaled to 300dpi and 24bit. They are out of focus because both versions of the stamp were originally scanned at 1200dpi to 48bit. The background (and background light source) matters. The 'yellow' squares on the left side are actually the same color as the 'blue' squares on the right. It's the whole blue/black or white/gold dress thing, if you saw that when it passed through the internet a couple years ago. Vision (including color interpretation) is contrast-sensitive (as opposed to luminance sensitive) so yes, colors really do stand out more against a black background than a white one. They look like the stamps I scanned on mine.īTW, people should use black backgrounds even when you're displaying your stamps. But that may just be a function of my monitor versus yours. I have to think the scans are dark mostly because the stamps are dark - I do use black matte when scanning stamps.
