Maarja:
Reproductions made from high resolution scans are fine for display
copies. You may also want to go ahead with the copy negatives for both
long-term preservation and disaster prevention purposes.
If you have a good deal of IT support and the services of a digital
object preservation specialist then 600dpi tiffs, with height and length
dimensions of at least 3,000 pixels each, RGB, at least 24 bit
truecolor, and preferably at 8 bits per channel make good digital
surrogates for color photographs. Black and white images, text,
architectural drawing, oversized or incredibly small items require
different standards.

Jeff

My thanks to all who have responded up to now, on and off List, with

Some of you advise having a 4x5 copy negative made, then having prints =
made from that; others advise scanning at a high resolution, such as 600

more detail. So, I should add that in this case, the project involves =
getting high quality copies made * in a quick turnaround * for hanging

photographs in an important room in our headquarters building. Of =
course, I am not going to turn over the only existing originals for =
hanging. Hence the need for copies. At this point, given the deadline

involved, speed (completing the project quickly, which means photo =
reproduction and framing) is the driver more so than re-use or other =
archival considerations.
Thanks again to all of you who have taken the time to consider this

you've been great!

Maarja,
Certainly the best way today is through scanning; either a high quality
flatbed or direct digital capture with a scanning back. The choice of
which
depends on a number of factors, including the condition of the print,
reflection problems, etc.
In terms of printing, both Epson and HP offer inkjet technology that
rivals
traditional photographic methods, and in many cases is far more
archival.

Subject: Question for photo experts (reproduction w/o negative)
This is very basic question but not one which I've encountered before,
at
least not recently. I didn't readily find an answer in the List
archives.
What is the best means of reproducing good quality copies of an older
8x10
print which was shot with 35mm film but for which no negative was
preserved?
I know the best reproduction would be off of a negative, but if you only
have the print, what method would you ask a photo expert to use to
produce
the best possible copy? Scanning? Or some other method?
Years ago I had to have some copy negatives made, but I was wondering
what
you photo experts would consider the best method of reproduction
nowadays.
Thanks, and off list replies would be fine!
