  1. Re: Midtone Machines - Automatic Film Processing Machine

    Midtone RFP-4? (rapid film processor 4, for 4 rolls of 35mm per tank)
  2. Re: Midtone Machines - Automatic Film Processing Machine

    Another new blog post, new company logo and some website updates: http://midtonemachines.com/news/new-logo-shout-outs-and-progress/

  3. Re: Midtone Machines - Automatic Film Processing Machine

    Haven't actually used any of the JOBO reels, I'll have to get my hands on some for testing. If they're smaller then maybe it would only require a different spindle to take them in the same tank...

    Re: Show Me Your Night Shots!

    Four hour exposure of a hut in New Zealand on Provia 100 slide film, unfortunately patchy cloud and a nearly full moon meant that I didn't get the star trails I was looking for.

    Re: Large Format Landscapes

    Hiking for three days in the wilderness with a large format camera is pretty hard on the legs! Got a few nice images through, slowly working through developing and scanning them.

    More progress, new custom PCBs are in and they've done a great job clearing up all the wiring mess, a much better solution for production. A few niggles with the pinch valves are holding me back a...
  13. Re: Midtone Machines - Automatic Film Processing Machine

    Yeah as I've said in previous blog posts I didn't intend for it to turn out that way when I started the project, I actually intended it to look a lot more like the filmomat, but as I started working...
  14. Re: Midtone Machines - Automatic Film Processing Machine

    PCBs are done and working, I've also put together a dummy body shell out of laser cut MDF for testing purposes, that I think also looks pretty good given that it's just for testing:

    Re: Large Format Landscapes

    Mix of Portra 160, Provia and Velvia. Actually digging the Porta a fair bit, especially for taming really harsh light.

    Re: Large Format Landscapes

    Cheers, if I had to guess I'd say it was just the lighting changing, there was small banks of heavy cloud passing the sun every few minutes so it was hard to judge when to take the shot.

    A bit of a slide vs. colour negative film comparison. Velvia 50 on the left, Ektar 100 on the right (both 4x5).

    Re: Large Format Landscapes

    A bit of a slide vs. negative comparison, Ektar 100 on the top and Provia 100 on the bottom. Kinda prefer the Ektar but that might be more because of the change of lighting between shots.
