I shot twenty years of films before going to a digital camera in 2000. I have many boxes of slides and photos in shoeboxes that never get seen. I used a scanner to scan my images before importing them to the Adobe Lightroom library. But the scanner is slow and cannot run with the new operating system. Recently I used my new digital camera to copy my slides into digital images.
Here are the tools that I used:
A 50 mm prime lens
A camera railing to keep the distance constant
A light source and the film holder from JJC
I used a Large JPEG setting to copy the image. It has made copying 35 mm film to high quality digital images a joy.
