graphic, I was not doubting your ability in what you do. I'm sure you know what you're doing after all these years.
Lowell. When I tried your method my scanned photos came out very small. As in about 1 inch by 2 inches and that is not acceptable on my photos. And when I tried resizing by percentages, I got 19200 x
I don't resave jpegs. I can in TIFF format, reduce dpi to 600, tweak what needs tweaking, then if I'm planing to upload to web, I "save as" to jpg, but keep the original TIFF format. I never overwrite the original either.
Also since you shoot JPEGS, every time you save that jpg you lose quality. Right?
And today I did as graphic suggested and scanned my negatives at 300dpi, the result was, they are still noisy. Not as bad but still a lot of noise in them. But when I tried to resize to print size, they were also fuzzy. You can scan a print at 300dpi, but a negative at 300dpi just is not as good enough in quality as I like to see in my photos.
