These parts made it work

I last posted this in DIY 2013, now lost in the time

I still have it, but moved on

Perfect timing ! I have been looking at making an 8x10 tailboard camera (foamboard and birch-ply, nothing tricky) and the associated enlarger during the winter, and in your illustration we see the infamous ArtoGraph lightpad!

There will also be a couple of versions (only on paper / text-file so far) of an Arduino based enlarger timer.

I have a four day working week, so my Fridays will be pleasantly busy in the workshop, and the weekends will keep on as photo and walking/climbing related days.

Now that I think about it

If using a led panel, why not project UP, as then the neg can lay on the lamp, no carrier needed

Never tried that

I was using the Saltzman stretcher in the image, in a normal config

Have you started your enlarger / timer design yet? I'm working on one myself (8x10 as well) and it would be great to compare notes if you want to.

Simple. Maybe somewhat effective. Seriously underpowered though - good thing today's neutral-tone VC papers are fast.

Well, the horizontal enlarger and the tailboard camera are one and the same, or that's the plan anyway, with a different foamboard back. It will be a wall-projection arrangement, but simple to setup as I have a laser-alignment tool.

So far I have found four 8x10" DDS, in surprisingly good condition, and sketched a scaling up of the back of my foamcore 4x5" camera. I've not yet considered the details of the neg carrier, which is not going to benefit from gravity as the 'cam-larger' thing has a horizontal axis rather than vertical. Initially I expect to use multiple spring clips and two pieces of picture glass plus a foamboard box holding the Artograph (or other lightsource), then develop* from there.

I've been playing this game too

Looks far far far more complicated

If I want color I use Digi

It's far^3 complicated indeed.
But also functional^3. That's the thing.
It's not hard to get 'something' to work with LEDs for B&W. Getting something to work WELL for B&W + color is a different story.
