Hi, I'm about to start the task of scanning the thousands of family photos we have from the 90s, 80s, and down to the 50s. Here's what I'm confused about. Right now, I have a Canon MP620 multifunction flatbed scanner. I've scanned a couple photos and they look alright, but I have no idea if or how much better another scanner could be. I don't know if my scanner is "good enough". Not sure whether I should use it or buy another one. One of the photos I scanned looks like it has pixels missing. When I zoom in really close in photoshop, one or two pixels will be completely white. The photo looks like its snowing. It doesn't appear to be dust, as the dots are too uniform looking. The photo is from the late 80s, could this be the ink coming off the photo or just reflection from the scanner light? The photos I have are mostly 4x6 inch prints. I also have some 35mm negatives, but I will need another type of scanner for these. I feel lost when trying to choose one. Could someone point me in the right direction? I probably have to keep the budget of this project under about $400. Thanks for any help you have.
