We'd love to hear some opinions on the following proposal:
The Royal BC Museum and BC Archives imaging department is thinking of
converting all their digitized image collections to a common colour profile.
This raises some questions:
1) Is this advisable? My feeling is that it would be better to just leave
the images with the profile of the scanner. Doing conversions would be one
more manipulation of the data in 8 bit format, possibly damaging it.
2) If we do go with a common profile then which one would be best for an
image archive? Is the Adobe RGB 1998 profile appropriate? The majority of
customers using images professionally would be using Photoshop anyway (I'm
making a grand assumption here! ;^), it seems a nice balance between too big
and too small and is widely available.
3) Another idea being tossed about is to store the images stripped of their
profiles to save download and storage size, and have the profiles available
for download separately. This makes sense from the point of view of storage
and download speed, but I wonder if it will become a management nightmare
as new profiles are generated over time for the various input devices,
which will include digital cameras.
4) One of the scanners is used in 'auto' mode so as to do as much colour
correcting as possible while still in the 12 bit scanner driver (its a fully
automated scanner, so no manual correction per image). Is there any point at
all in trying for a profile here?
5) Maybe it is best to leave things as they are: not colour managed. Many
images are old and not exactly the best quality, so the changes that a
profile will make might be minor at best compared to the changes people will
want to make to the images anyway.
Sorry about the lengthy post. It's a serious issue for us with long term
consequences.
The museum and archives are considered educational institutes and are
mandated to foster understanding of British Columbia's natural and human
history by the gov't of BC.
Thank's for your input,
Andy
