This doesn't quite answer the question but addresses the issue of what is worth stealing. We tried some comparative print tests of raw and derivative jpeg images. Raw images were uncompressed tiff approximately 4000 pixels square, the scaled and compressed images were scaled to 1600 pixels and jpeg compressed using Photoshop setting 8. The resulting images were about 1 MB in file size. We printed a range of sizes from 4" x 6" up to 24" x 36" - postcard to poster size. In blind tests most people couldn't tell the difference even at the largest size, only the trained eye could reliably differentiate and not without close examination. While you might expect this result for the smaller prints, the poster size print result was interesting. The largest size was printed to canvas which helped in disguising the artefacts and used a Light Jet printer. -nik Nik Honeysett Head of Administration J.

>>> "Real, Will" <RealW at CarnegieMuseums.Org> 9/6/2007 6:19 AM >>> Matt's comment about image size leads me to wonder what members of the MCN community think is the biggest possible image that would not be worth stealing for financial gain. Here we have settled on 500 pixel images, but that was fairly arbitrary.

Or if certain particular groups of users like zooming? I often find zooming irritating. I would mostly rather have a single, somewhat larger full view of an image than to zoom in on just a piece of the image, even if the detail is not as good. Zooming takes more clicks & drags, and then I end up with something where I can't really see the work. I just wonder sometimes if the effort we put into zoom is worthwhile. Should we just make the images bigger? I know that ours could be a lot bigger before it's possible to get any financial gain by stealing them.
