Last post I showed off some renders of custom PCBs I'd been designing for the machine, and today I'm happy to say that I can show off the finished things!
Just like a duck on the water it may look calm from the outside but I've been churning away furiously in the background designing some custom PCB's (printed circuit boards). Generally I'm a person who values real progress over stunts and so I...
We've been playing with Kodak's Ektascan Xray film. Cool stuff. It has a tabular grain (rumor is that it's the same emulsion as their TMax but without the panchromatic dyes) and is single sided. And cheap, about a buck a sheet for 8x10. Of...
Sorry that it's been a long time since my last post but there has been a ton of progress since then! Still on track to develop some film by the end of the year
As those of you who read the Facebook page would know, last week a set of vacuum resin cast parts arrived, enough to make 10 machines! Vacuum resin casting is a rapid prototyping technique to make strong, high quality and fully functional parts...
I wanted to test how lens aperture affects to the sharpness of the print.

Some good news in this update, the sheet metal parts for the development machine have arrived (and look great), the pinch valve has done over 16 thousand cycles now and still works fine and I’ve done some quick and dirty pumping tests which were...
Rumours of my death have been greatly exaggerated. Sorry that it's been a while between blog posts, I've been dividing my time much more between my day job and actually getting out and taking photos as opposed to developing them. It seems that by...
MIDTONE MACHINES Photographic film processing for the 21st century 3D Printed Goodies! As I mentioned in my last update I was having some parts of the developing tank 3D printed so I can do trial fits and see if anything needs to be...
In today's blog post I'm going to go into detail about the developing tank design, where chemicals and film meet. The developing tank needs to do a few important things...
MIDTONE MACHINES Photographic film processing for the 21st century Real Meat and Potatoes Stuff Now that we have an understanding of our requirements it's time to get down to business and do some system design work. This post is...
Who doesn't enjoy a tasty pie chart? In order to better determine what the market wants/needs in a film processing machine I distributed a basic questionnaire to a number of people in my target audience (small commercial labs/people who develop...
Cliche but I think it's an accurate sentiment when it comes to most things, engineering especially. It's very rare that something truly new emerges from the wild, most of what people would associate with innovation or progress is the summation of...
Welcome to Midtone Machines, my name is Andrew Burns, a rocket propulsion engineer with a passion for film photography. I've started this blog to allow you to follow along with the development of my as-yet unnamed project, and hopefully so that...

Ilford makes Delta 3200 B&W film in both 35mm and 120 formats. This post compares the two formats shot with the same settings and similar focal lengths. We love the look of both but there’s a noticeable difference when it comes to the grain...
It's an interesting thing returning to an old camera after not having shot with it for a while. Usually it is setup just as you last left it, just now perhaps with a slight dust layer on it. If you are at all like myself, who's had been sitting...
The basic unit with the connection lead for a hot shoe. Fittings are supplied for Lomo cameras. The rubber band and luminium plate are for universal fitting to an SLR. The unit is attached to a Pra…
