Re: [MCN-L] Digitizing Photographs

2015-01-27 Thread Kate Blanch
Hi all, I'm grateful to read all the feedback on this topic! I wanted to expand 
the conversation a little and ask whether anyone has experience digitizing 
documents via a copy stand set up? The flatbed scanner approach is just 
painfully slow.

We're working our way through a planning grant to develop a plan to digitize 
about 34K pieces of documentation related to the museum's collection (I know 
this crosses over into archival work, but for the sake of looking at 
digitization only, just go with me). 

The oldest documents in the set are about 100 years old, though the oldest 
documents account for a very small percentage of the whole. There are some 
handling issues, but again, marginal overall. 

Any thoughts on flatbed vs. copy stand for digitizing documents?

Thanks!

the flatbed scanner. Using a copy stand is a good approach, however, unless 
your organization has the resources and money to hire (or find a

measure and balance light and tone, you are more than likely to wind up with a

Re: [MCN-L] Digitizing Photographs

2015-01-23 Thread Tanner, Simon
I would say that I would be much more concerned about the heat on the glass bed 
of the flatbed scanner than the light exposure. Those beds get pretty hot after 
multiple scans and this can do an awful lots of damage by activating dirt on 
the surface of the photograph or causing chemical reactions within the 
substrates.

This can easily be alleviated by running two imaging rigs so that one is 
cooling as the other is imaging so the bed stays relatively safe heatwise but 
this comes with obvious added workflow complications plus space and hardware 
implications.

Re: [MCN-L] Digitizing Photographs

2015-01-23 Thread Landsberg, Erik
There are many considerations to be taken into account, and the best
solution will be particular to each institution and project.

I've noticed a few references to the heat produced by incandescent lights
on a copystand. For the record, flash is highly preferrable to incandescent
in most copystand setups. Flash generates almost no IR and it's UV can
easily be filtered.  In greater sharpness (compared to incandescent, which
commonly requres slow shutter speeds -- subject to vibration, etc.)
frequently results. The sharpness advantage is due to exposures that use 1
extremely brief pulse of flash light, which can be as short as ~ 1/5,000
sec., depending on equipment.

Of course the camera/strobe approach requires additional expertise. But the
lighting setup can often be done once and locked down for use by less
imaging-experienced staff.

Yes, I’ve used flatbed scanners everywhere from the National Archives to medium 
sized art museums in the Midwest. As Joseph stated - it all depends on the type 
of image - super uber fragile or not. 

I’m not a conservator - but, I figure using a flatbed scanner and the fear of 
light damaging the image…wouldn’t it only damage it noticeably if you use the 
scanner light repeatedly? (sort of like taking multiple flash images of a 
painting for 100 years over time..). 

And yeah, I’d just hire a consultant/contractor to photograph delicate images. 
So you don’t have to invest financially in fancy pants camera equipment.

Re: [MCN-L] Digitizing Photographs

2015-01-22 Thread Rob Lancefield on lists

Matt and all,

As two cents from a non-conservator who cares for a collection of works 
of art on paper (including their digital imaging), these days 
camera-based capture does most often tend to be best--safe, accurate, 
fast--with these materials, but each situation can be different.


Your one specific factor of light intensity and duration actually may or 
may not be a concern with flatbed scanning of original photographic 
prints, depending on the specific scanner and the settings used with it, 
as well as the specific photographic media involved--for example, 
well-processed gelatin silver prints, versus more fugitive media.


That said...in most museum contexts, other preservation concerns make 
digital photographic capture vastly preferable to flatbed scanning for 
works on paper that are considered part of the collection as such, as 
distinct from photographs considered to be internal documents, etc.


These concerns arise from the need to place original works face-down in 
physical contact with the scanner, and one after another. Depending on 
the physical attributes of each photo (its surface, condition, etc.), 
that contact can raise concerns about causing subtle surface damage, as 
well as about any possible transfer of unseen contaminants--e.g., mold 
spores--from object to object, if one early in a run has such an issue.


(Also, if any of the photographs are matted, the significant handling 
risks of flipping them over and down onto a flatbed while matted, or of 
unmatting and rematting each photograph, could both raise more acute 
preservation concerns and seriously slow down your capture workflow.)


So, depending on your situation, it may well be much faster and safer to 
run rapid, camera-based capture instead, especially by the time you 
factor in the need to assess any object-by-object risks of scanning.


But over to the conservators! (Is Dale Kronkright in the house?)

hope this helps,
Rob

Yes Rob. Scanning photographs will reduce its life. Better to photograph
the photograph, and preserve it in a master uncompressed digital format
(TIFF) and as a second printed analogic source.
Unless you manage to have cold light scanners, which flatbeds are not.

Re: [MCN-L] Digitizing Photographs

2015-01-22 Thread Landsberg, Erik
 If it hasn't already been said, photographing in a shoot-down copystand
setup will also allow you to avoid the glare from certain glossy and/or
rippled prints that frequently occurs due to the frontal lighting of a
scanner. For especially stubborn glare, the copystand approach also permits
you to use partial or full polarization when necessary. This is also
helpful for controling reflection from silvering that often occurrs
around the edges of older gelatin silver prints especially those that have
not been archivally processed.
So, copystand: faster, safer handling of objects, better light control.

 Yes Rob. Scanning photographs will reduce its life. Better to photograph
 the photograph, and preserve it in a master uncompressed digital format
 (TIFF) and as a second printed analogic source.
 Unless you manage to have cold light scanners, which flatbeds are not.

[MCN-L] Digitizing Photographs

Good afternoon. We have a collection which consists mostly of black and
white photographic prints and are beginning to digitize them using flatbed
scanners. However, I spoke to a conservator who advised that they be
