Image Acquisition Continues

This year's Czech trip has several purposes--among which are doing research for new projects and seeing friends--but the more pressing project is, of course, image acquisition for Magnetic Woman. I knew when I began that image acquisition for art history books generally takes quite a bit of time and money, but each book has different needs and I didn't really have a clear sense of where my own time and money would end up going. I did know that I had taken a lot of photographs myself of Toyen's book illustrations, which meant that while I'd still have to pay copyright clearance on those, at least I wouldn't have to pay for the photos.
Yes--payment is usually a two-step process. First you get a photograph (these days typically a hi-res digital image) of the work, which can be anything from free to hundreds of dollars per photo, and then later, if the work is under copyright, you pay to clear copyright. In other words, you tell the copyright clearance people what you want to use this image for, how big, whether in color or b&w, etc., and they tell you how much it will cost.
An area where I've made nice headway since coming to Prague is that of getting photos of Toyen and her associates. I knew that the Památník národního písemnictví (PNP), which although an archive of Czech literature nonetheless is a major repository of art-related materials, had some of these photos. I also knew that the design museum (UPM) had purchased Jindřich Štyrský's photos, which included at least one of Toyen. I've worked with both of these entities before and am pleased to say that both responded very appropriately and professionally to my inquiries about photos and that I have now paid for and received most of what I requested. (One photo still has to be scanned by the PNP, and there are one or two artworks I may also request from them which are handled by the art side rather than the literary side.) This is all good and a great relief.
There remain some photos I'd like to get--photos of photos, that is--but I'm not sure who has them. Usually publications provide individual credits of who something belongs to, but some of these photos have been published without a specific credit, which is unhelpful.
Acquisition of photos of paintings remains even more difficult than I had anticipated. I knew that it probably wouldn't be easy to locate photos of privately held works, but it never occurred to me that several museums and galleries would simply not respond to emails. Kudos, therefore, to the museums that have already provided images, whether free or fee!
