Is it just me? Things on the forum are so quiet.

Well, I guess the summer heat has gotten to everyone?

Anyway, I attended a scanning seminar hosted my Imacon, and got a sample scan 
at just 400dpi from a 6x7 side. Beautiful. Just beautiful. What a great 
scanner! Although I printed somewhat larger than the recommended print size 
as explained below (at ca. 150 dpi), it was still just beautiful.

I also learned a couple of things in my ongoing search for answers to 
scanning issues.

Well, if you own an Epson, you can safely print at 200 dpi. That is:
the file's resolution is just 200 dpi. The printer's dpi output is 
independent from this and thus another story; just remember: the higher the 
printer's dpi output, the better and denser your print.

But knowing  that 200 dpi of the digital file for pinting is sufficient, 
follow then this simple calculation formula:

Scanning resolution x size of fim in inches divided by 200 gives you the 
output size at 200 dpi.
(for example a 2x7 inch slide scanned at 1200 dpi will at 200 dpi output from 
your digital file print this size: 42 inches wide by 12 inches high. 

or:

Targeted output size, multiplied first by 200 and then divided by the size of 
the original in inches, will give you the needed scanning dpi.

Thus: 42 inches desired: 42x200=8400
8400: 7 = 1200 dpi scan needed.


Thus, if you want to print out a 35mm slide uncropped to 8x12 size, you'll 
need a scan at 1600 dpi, using the Epson at 1440.

If you want a 12x18, then you will to scan at 2400 dpi.

If your film scanner has let's say 4000 dpi, then you can print your 35mm 
slide at 20x30 inches. And your 2x7 at a whopping 140 inches long. 

If it only has 800 dpi, like the new Epson Expression 800, then your output 
size is only 4 by 6 inches for a 35mmn slide, and 28 inches for a 2x7 pan 
slide.

I think this is probably already clear to most of us; but since it is so 
quiet on the Forum, I'm sure you don't mind at least one member blabbering.

A remember, you won't get good results from interpolation!!!!!!!!!!!
Thus if Epson says it is a 800x3200 scanner, remember that the scan is really 
only 800dpi and that the 3200 is interpolated!


Reactions anyone?
