since there are a few threads going around about res, prints, enlargements

and a few divers asking the basic questions:

High end prints, postcards, calendars and things from pro printers require 300 dpi resolution.

i use the printer linked below for that.

In my experience acceptable prints can be half that.

Thus a 35mm slide can be blown to (35 x 4000/150)= 933 mm or 36 inches to get "acceptable quality). 11 x 17 for good quality

as for digital. a 6 MP camers (2 x 3example) might give a 20 inch max acceptable print. 8 x 10 for good quality.

and it goes as the square rememeber. a good quality 16 x 20 print requires 36 (6x6) megapixels (100MB) of information

for acceptable quality prints I go here


for the postcards and calendars I go here


I as well as Chris scan at 16 bit, do some manipulation, and drop it down to 8.

I no longer see the need to actually send a slide or neg to a printer

all done electronically. youll need a broadband connection
