Absolutely on shooting in RAW. While noted earlier, I do have a Epson scanner but the high dpi scans are slow and jpg output (never tried tif with slow scanning) was limiting in post. This tread got me to thinking and with available resources built the DIY project for free. RAW output was outstanding and while able to correct aged color degradation would be expected, but the ability to pull shadow detail from a dark slide that didn't show on standard projector viewing was amazing. While posted one today on POTD, will probably post the shadow pull tomorrow.
This was really a simple build. Wired tether to computer and 27" monitor simplifies focusing detail. Interior of box white lined and taped seams for color balance. Cut green hanging folders - didn't have black paper - to minimize reflection back to lens impacting exposure. For photo, video light turned down, but in use much brighter.
Now that I know it works and the advantages of RAW...it will cost me. Will probably rebuild as wooden box and anti skid/vibration on bottom. Cut light opening 120 film size and design 3 overlays for 35mm slides, 35mm film transport path, and 120 film transport path. Keep the straight in design rather than top as allows standard tripod setup. The only big, and expensive, issue in my macro lens needs to be upgraded. In theory, you can use extension rings with any lens for macro effect, but a true macro is far preferred both for sharpness and flatness of field. Shown is an ancient manual only Sigma 50mm macro on a Nikon mount with a Sony converter which may impact the 1:1 as I had to do slight cropping in post. Also, no electronics so nothing is transported to the camera/EFIX data. A macro in the 90-105 range should resolve those issue...but I know it works.
