We can all agree on the importance of recording the technical info for each shot you take. We can all also admit that most of us don't do it. At least not consistently. Frankly, part of the problem for me, was finding the right notebook. I've...
Hi all, apologies for the long time between posts but I think we can all understand the obvious reasons there could be for that, given what's happening globally right now, and I'm sure everyone will appreciate me not going on about it.
You might notice there have been a few changes to the website, hopefully between now and when I start to push towards crowd-funding and selling this machine the website will get spruced up a lot as it transitions from development blog to company...
Today I've put together a short video update (I really hate editing videos). Hopefully this shows you a little bit about how the machine will eventually operate and more importantly how the user will interact with it.
I've actually been pretty busy since my last blog post and that's a good thing as it's all been solid progress (even the things that sometimes feel like backwards progress...). First up, I've completely pulled the machine apart and re-built it...
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.
Leica IIIC camera with 1960s-vintage Canon 50mm f/1.4 ltm lens Background Long-term readers recall that I have used my d...
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...
