Does anyone know how much difference there is between a 1200dp x 1200dpi vs 600dpi x 1200dpi and if it will make a difference to me (mostly for casual use etc...)
Actually, it does it from CS2 onwards. Not sure a spoiler is necessary really, but if anyone wants to find out for themselves, then fair enough.... Spoiler You get a dialogue error warning saying that "This application does not support the printing of bank note images".
How does it know you're scanning banknotes rather than really low-quality pictures of the Queen? Something to do with the cotton? Or the ink?
Must have a database of images it compares the scanner or TWAIN driver output to. Spoiler It's not only if you scan it straight in to PS either... scan it elsewhere and load the image up and the same happens. Dunno why I'm using spoilers... it's not like I'm posting the conclusion to lost, or REAL Fermi benchmarks I guess I'm just feeling the cloak and dagger shizzle.
True.. apologies. For casual document use, it makes no appreciable difference whether it's 600x1200 or 1200x1200 resolution. In fact, most cheaper scanners will have an optical resolution lower than this, and will interpolate the image to a higher resolution. Only higher end scanners have an optical resolution this high. It only becomes an issue with scanning film, and usually you won't want a flatbed scanner to do this. As most people will have 35mm negatives anyway, pretty much ALL flatbed scanners are useless at scanning film this small. Only if you have medium format or higher film does a flatbed make a decent job of it. If you want to scan 35mm film, get a dedicated film scanner. For casual document scanning, don't worry about it.
