This nip2 workspace is for working with technical images of museum objects. It is useful for colour calibration, preparation of false-colour images, and calibration of fluorescence images.
The development of these workspaces was funded by The British Museum under the EU CHARISMA programme. They were developed by Joanne Dyer, Giovanni Verri and John Cupitt.
For this workspace to work well, you need to take care importing images from your camera. The workspace assumes that the ICC profile attached to the image will not apply a tone curve.
In PhotoShop, turn off everything you can, and select no tone curve.
You can import with rawtherapee like this:
$ rawtherapee -p rawtherapee-import-params.pp3 -t -c *.CR2
where rawtherapee-import-params.pp3 is in this directory.
nip2 is the GUI of the vips image processing system. In April 2020, the current windows version is 8.7.0 and the current macos version is 8.6.0.
On Linux, start your package manager and search for nip2.
Start nip2 and drag bm-workspaces.ws into the main window, or alternatively
select File / Open. The workspace needs nip2 8.2 or later.
There is a manual on how to use the workspace on the British Museum page for this project:
http://www.britishmuseum.org/research/research_projects/all_current_projects/charisma/technical_imaging.aspx
charisma-bm-workspace.ws is an earlier version of the workspace which will
work with older versions of nip2.
bm-workspaces-perugino.ws is exactly bm-workspaces.ws, but set up to
process a sample set of images of a drawing by Perugino.
CHANGELOG lists the changes made to the workspace over the years.
TODO lists a few ideas and issues.
