I didn't want to keep a bunch of negative images around so I was OK with that. This specific command would replace the image with the negated version of same. The command to convert one image is:Ĭonvert -negate IMG_8560.JPG IMG_8560.JPG I used the command line utility that comes with Imagemagick called simply "convert."

Sorry for all of the Mac and Windows users out there, you really should try Linux. A square would help but you could probably get by without it.Drill bit that matches or is slightly larger than the diameter of the screw (1/4" in my case).A scrap chunk of wood to use as a buffer between the upright arm and the camera.A 1/4" screw (or whatever fits your camera tripod mount).I used flat black square ones that I could stack double thick. If you can find frosted or white Plexiglas that might be ideal. A tablet with a screen based light application.If you have a light table you might be able to skip some of this 2-3 wood screws to attach the upright to the base.I used 3/4" plywood scrap about 24" long Scrap wood to build the base (or premade wood box as I found).What I came up with was cheap, easy to build and produced results I am happy with. I did some research and professional tools were far too expensive, I searched for DIY solutions and took some ideas from a few of them. I have a 35mm negative feature built into my multi-function printer but didn't have anything that would fit these negatives. My wife recently returned from a trip to visit family with a stack of large format (not 35mm) negatives.
