[PRCo] Re: Pittsburgh slides

[John F Bromley]

Bob, there is no need to store TIFF files at such a large file size.  I did
this for the first two years until I figured it out and stopped.

I regularly scan mine in (Nikon 4000) at 4000 dpi and reduce the file size
to a one-inch file at 1500 dpi, which will generally store at about 4-5 MB
each.  (I won't go into file manipulation for straightening, color
improvement, brightness, you'll figure all that out - but remember the
saturation key after using brightness improvement - REALLY improves the
slides as long as you don't overdo it.

When I want an 8x10 they can be expanded to larger sizes, time and again if
need be - TIFF files do this without loss, unlike JPEGS.

When printing I use 300 dpi - anything more is complete and total overkill
and gets you nothing except losing time while it loads.  Trust me I've done
side by side comparisons and I think the 300dpi's are better, since they're
not trying to slather ink into the same space and put too much down.  Fast,
great looking.

Save yourself some time and space.
