Out of curiosity I tried darktable for this, but my attempts to invert the raw files have been failures. I then bring the positive images into Gimp for cleaning up, sharpening and any fine tuning before printing. RawTherapee does an excellent job of inverting the raw files and adjusting tonal range etc. For this I use a Nikon D7100 (24 mp) for 35mm and a D800 (36 mp) for medium and large format film. Part of my work involves sorting, scanning and archiving a large collection of historical negatives and transparencies. I have but haven’t tested the Negative Supply 4x5 frame.RawTherapee has been my primary raw converter for at least a couple of years.I still send my color film out to a lab, and don’t have a good way to scan 120 film.
It works well, but I’m sure there are almost-as-good options that would be less expensive. The Negative Supply carrier is pretty pricey, as much as a DSLR and lens.Plus, I didn’t have to spend extra money on the camera. I’m using a crop sensor camera, so I’m not getting the most possible resolution, but it’s more than good enough for my purposes, and properly archived negatives will be around for years for re-scanning or printing.Finally, I export the images as JPG files and back them up to Google Photos and my other photo storage options.

I haven’t yet found any automation for inversion that I’m happy with, so it’s currently still a manual process. I manually invert the curves and set the D.max based on the film base.

From there, I open the raw files in darktable, my F/ OSS image editing software of choice. I use the full-frame guides, so I can capture the full, uncropped image.Įntangle also bypasses the camera’s local storage, so each time I capture a frame it’s stored directly on my laptop. I am not using their freshly-launched motor drive, but for now it’s fine for me to work manually. It’s pricey, but works very well, and is vastly superior to flatbed scanning for 35mm film. In order to position the film, I use a Negative Supply 35mm carrier.
I have to manually set the exposure with the aperture and shutter speed, but once that’s set for a scanning session I can just advance the film, capture a frame, and move on. Luckily for me, Entangle is a Linux program developed for exactly this need, and it supported live preview on my laptop out of the box. I discovered as soon as I received the lens that the D3300’s Live View function doesn’t support non- CPU lenses, so I started to investigate tethering options. Both of those items limited my choices somewhat, since Lightroom (and by extension Negative Lab Pro) doesn’t run on Linux.Īfter some advice from my mentor, Renato, I purchased a Micro-Nikkor 105mm f/4 AI lens from KEH to use with the D3300. My laptop falls into the same category: it’s an aging-but-serviceable Chromebook Pixel 2 running Gallium OS, a Linux distribution built for Chromebooks. My only digital camera is a Nikon D3300 (using Nikon’s DX crop sensor), and while it’s not the newest model it works consistently well so I have no desire to upgrade.
