Hi a photolab has provided me film scan information like 4 base and 16 base with image size at 72 dpi jpeg format. Is this good quality and can this make a good detail 8R print ? Dont really under the 4 base and 16 base . Any one can help ? Thank you .

Scan resolution--Softcopy: base/16 (128×192), base/4 (256×384) and base (512×768); hardcopy: base (512×768), 4 base (1024×1536) and 16 base (2048×3072).
Hi,
Though not conversant in the trade of scanning and printing, here's my attempt at interpreting Isisaxon's explanation.
4 base scanning yields an image file of 1024x1536.
16 base scanning yields a image file of 2048×3072.
(In addition to his numbers, also see http://en.wikipedia.org/wiki/Photo_CD for starter intro)
Print-wise, an 8R print is 8"x10" (http://en.wikipedia.org/wiki/Photographic_printing). For good detail, you should print at 300dpi, so a 8"x10" print requires an image file of 2400x3000.
Matching the scanning/printing, you can see from the above that the 16 base scan should give a file that will be close to 300dpi printing, so my guess would be yeah - 16 base scan should be OK for printing at 8R sizes.
HTH. Additionally, hope I am correct

Correct.. I was still thinking how I could explain.
