Hi all,For anyone interested in the approach that Corey took to analyzing these files, he has agreed to do an informal demo of his process where folks could ask questions. We've set up a time on Friday, May 10th, 9amCT/10amET. If you are interested, please let me know and I'll be happy to send you the Zoom link and/or a calendar invite.Best,LaraOn Fri, Apr 19, 2024 at 3:17 PM Lara Friedman-Shedlov <ld...@umn.edu> wrote:Interesting! Thanks Corey. I looked at a sample file in a hex editor and experimented with lopping off some stuff at the beginning of the file, but I don't know that much about editing files at that level, and the file I ended up with would not open in Irfanview, so I probably didn't delete the correct bytes for Irfanview to understand the file.deark looks interesting, but I don't know how to "build" it to work on my system.Thanks for experimenting and let me know if you figure out anything else worth sharing./ LaraThanks, that worked! I took a look at the files and they're actually Kodak Photo CD's embedded in the PICT format. I removed the first 1200 bytes or so to get to the PCD format and I was able to successfully open the files. The two smaller ones you provided didn't actually appear to contain photos, but 01 and 08 were easily viewed in Irfanview after the modification.I also identified another tool named "deark" (https://github.com/jsummers/deark) which can identify the original PICT format and extract the qtif file first, then the PCD from that for viewing.I'm going to take a closer look at the PCD and PICT formats to see if there's already a library or application which can read them natively without modification, however the manual method I described above, and the "deark" method can both be automated for rapid extraction if necessary.I'll keep you posted on anything else I find.Cheers!CoreyOn Thursday, April 18, 2024 at 11:45:12 AM UTC-4 ld...@umn.edu wrote:YIkes!

I tried a lot of programs that people suggested (Irfanview, GIMP, Imagemagick) and none of them worked for me. One person said she was able to open the files with Irfanview after installing the Quicktime plugin. Unfortunately, I couldn't get that to work when I tried to do the same.What did work for me in the end was installing a copy of Quicktime Player 7 PRO that I downloaded from the Internet Archive. You can also download a slightly newer version from https://support.apple.com/en-us/106375. The license key that is packaged with the zip file that you can download from the Internet Archive works to activate either version. I was able to view the files and even export them as jpgs, though the latter only worked if I used the "export for web" option (not "save as"). The "export for web" option creates a folder with several files, including a jpg. I also discovered that if I do a custom installation of the Quicktime program that includes the "Picture Viewer" component and use that to open the .pict files, I have the option to export as a jpg.Hope this helps someone else!/ Lara

Does anyone have any tips for what could be used to open and convert these images to something like a .tiff?I tried opening a few with Adobe Photoshop (on Windows) and got a message that said:
“the PICT is too complex to open on this computer. Photoshop Windows supports raster PICT files only.” I then tried opening one in Adobe Illustrator and got a message that said "“QuickTime and a Photo CD Decompressor are needed to see this picture."I also tried opening the files on a Mac, but the Mac I have access to doesn't have a lot of fancy software. The files would not open in Preview.Thanks in advance for any tips!/ Lara-
