Digitizing

I recently ran a ("slightly" expired) Kodak Gold ISO 200 film through my Exakta Varex 1b.

And I want to document the procedure of digitizing those images for further processing. As I do not have a scanner around, I decided that for me, the quality of shooting them with a digicam is good enough.

I set up my GH4 with a Metabones Speedbooster, a bellows and the Minolta 35-70mm f3.5 (non macro). In front you should put consistent light to expose all your negatives in the right way and to avoid color shifts. I put a CN-160 LED light with a diffusor in front.

Find a zoom and bellows position, where you get the full frame. You can fine tune with focus.

Insert an unexposed part of the developed negative and do a custom white balance.

You should focus for the grain layer. I set f-stop to f8. Depending on your rig, you should check focus from time to time.

Shoot pics of your negatives. Compared to scanning, this is now a very fast process. You can loose that time easily on post processing later...

Now put your memory card to the computer and get Raw Therapee http://rawtherapee.com/ . As far as I know, it exists for all platforms.

Fire it up and navigate to your Memory card.

Then you can start on a negative shot.

Inverse your tonal curve and align it to your white and black points in the picture. From here on, all controlls go inverse. So Black is White and vice versa. You will see what I mean. Maybe there is a better way that I don't know of.

Then check for the Camera white balance setting. I did slight adjustments to white balance first. Also you can compensate exactly in case you have a color chart shot ;)

Compress highlights and Blacks as you like, add vignette compensation, sharpening and so on.

Rotation and Cropping is also very fast and intuitive.

SAVE this as a Preset and load it on the following picture. Create multiple Presets.

Save your file straight away or send it to the processing.

I did some extensive color management, denoising in RawTherapee and scratch removal afterwards in Gimp on the following one:
