- This is a second and very much improved version of a difuser head that can be adapted to an existing enlarger. In this project it was designed to fit on a graflok back transforming a 4x5" camera into an enlarger.
The video is a complement to a full and lengthy project description available at the following link:

The instant I saw you were incorporating a Linhoff in this project, I knew you were my kind of nerd! Well done sir, bravo!
What an amazing creation and a generous heart to share all of your work and knowledge!
Great video, thank you so much. I always wanted to make one of those, but with flash and a condenser. You may enjoy this story - - I used to work a large tricolour copy camera that one would operate from within, the intent of which was to reproduce large colour copy work directly to a Fuji photo paper, processed using Cibachrome chemistry, one generation…there was a room, probably 20 x 30 feet, attached to another at 20 x 6 feet. They were separated by a wall with a lens turret and a filter wheel. The large room had copy lights, a vertical vacuum board on a focus rail and the exposure controller. The other had a front-faced mirror to reverse the image and direct it to a horizontal vacuum board, and the shutter release. There were a number of gorgeous, massive Schneider lenses. The filter wheel had three round gates, two of which were occupied by narrowband filters (blue and red, if memory serves) with one blank for white light exposure. Colour balance AND print density were simultaneously controlled by duration of the exposure through each of the three gates. There was logarithmic math you could do to figure it all out, if so inclined. Totally bizarre camera/enlarger. Loved it. Thanks for reminding me of it.
I wish I was smart enough to made this. Amazing!
happy to have found this was researching 'intrepid's 4x5 compact enlarger and discovered their 'LED' source isn't up to the task in regards to making use of their Ilford based contrast filter system.
Outstanding. I am in the middle of a Green/Blue LED head project, but this will make me reconsider an RGB solution. Very tidy packaging as well. Thanks for making the project publicly available as well.
I am especially thinking of the possibility of obtaining 16x20 "images from an 8x10" camera, without needing a huge enlarger!
A big thank you for detailing your project. This will avoid many hesitations and mistakes for those who would like to realize it.
I just came across your video. I have an enlarger that works on the same principle I believe, the Philips PCS 130/150 which uses additive RGB and the intensity of each is controlled by the control box. I love what you have done here, especially the adaptation to the Graflok back. Bravo sir.
Very nice project and considerate.
Excellent work! I love that you etched your own PCB too!
Wow! Thank you for sharing this great project !!!!
This is an excellent video, thanks so much for sharing your expertise!
Thanks so much for sharing your knowledge....well done!
well thought out. will pass along
Awesome, I think I'll adapt this to my DeVere 507 for using it instead of the dichroic head with halogen bulbs,
That's awesome. Thank you!
Well done!
Wow, great job!
Thank you!
Thank you! Grande projeto!
Maravilloso proyecto!!!!.
Very nice project. Why the multiple flashes?
Multiple flashes are useful to make test strips in order to find the right exposure time. It is also a good thing when doing dodging and burning.
12:12 Make a video (or a description) of how you made that rocker, please!
Hello, I included a short video showing the device. It is very simple and a good "helping hand" in the darkroom. Go to the project web page and you will find it in the PCB making chapter.
