The scanning kit's 35mm film and 120 film scanning methodologies are virtually the same, though you'll need to adjust the camera's height to ensure each negative fills the frame. This once seemingly complicated process has never felt more straightforward.
1. Mount the camera, with a macro lens attached, to your riser (aka copy stand). You'll most likely want to invest in a level to ensure that your camera is perfectly balanced.
2. Grab your light source and plug it in.
3. Get your holder, and you'll find that it perfectly aligns with the light source. See how easy it is?
4. Plug your tether cable to your computer and start up your software (Lightroom, Capture One, etc.) *This step is optional, and you can shoot to a card, but I find it easiest not to have an extra step of importing later. Plus, you'll be able to see your images more straightforwardly and ensure they're looking good.
5. Load your film into the scanning carrier and make sure it's flat and centered.
6. Turn your camera on and switch your lens to manual focus. Make sure the camera is focused on the image's grain.
7. Set your camera to manual and ensure that your image is well exposed without clipping in the highlights/shadows. I used ISO 160, shutter 1/5 and an aperture of f10 for this example.
8. Start snapping your frames until you're all done. This is where having uncut film helps to speed up this process, but it's not too much longer if your film came back cut from the lab.
9. Convert your negatives to the post. I used the Negative Lab Pro plugin in Lightroom, but you can do it manually in Lightroom, Photoshop, or use another plugin of your choice.
