UPDATE 8/29/2019 - added untested 35mm top plate UPDATE 3/29/2019 - added missing base plate files Another "resolution" I have this year is to finally digitize all my old medium format film negatives. Commercially available film scanners that support 120mm film are either expensive or low resolution. I designed this film scanner as a way to use a regular digital camera to capture the negatives so that they could be inverted in Photoshop. This is a series of plates and a camera hood for scanning 120mm medium format negatives using a digital camera and a light table. The bottom plate requires the use of a sheet of 0.093" thick acrylic, I got mine from Home Depot for less than $5. This should in theory work for any camera, only the lens hood would need adjusted for your model. The included lens hood is for a Canon SX40HS point-and-shoot digital camera. It sits just inside the lens, against the plastic that surrounds the lens element. Using the SX40 in manual shooting mode, the focus is set to about 1.5 inches, ISO 100, aperture at 2.8. I adjust exposure by changing shutter speed. I also use the self timer at 2 seconds to be sure I do not shake the camera when capturing the image. The attached photos were scanned in this manner. The original scans are much better quality than seen here, you can easily make out the film grain. Also included is a parametric model of the lens hood that you can customize in SCAD for using a different camera. This is now a universal film scanner for medium format film! You can download the latest build of SCAD and enable the customizer, or just edit the first few variables yourself - it's easy! The lens hood has been updated so that it no longer sits inside the lens touching the glass. Now the rim of the lens should sit on the small ring with the cylinder surrounding the lens housing by 15-20mm. this will stabilize the camera and help block light.
