Hello fellow Columbusian! I saw some of that Broncolor gear at Gary's too and was crazy tempted to buy it. However, at the time I looked, he only had packs and no heads. I was concerned that the...
Can't speak for anyone else but I can answer based off my practice: There's two factors that lead to a lot of plates looking pretty dark. First, wet plates take a shocking amount of light to expose....
Printing on silver halide paper often has exposures in the 10 second range and we don't complain about a lack of accuracy and control, we just use a timer.
Do you have a link for an example of these bars? I haven't heard of them before.
I suspect the softness that made you ask that question is front tilt kicking the plane of focus over so that the in-focus bit of the floor is between the camera and the model but out of the frame.
Is there a functional difference between using aperture rings as shown here and just closing down the aperture diaphragm (if equipped) on the lens itself?
Thanks!
Yes, I seem to be able to use a LOT less light than most other people. I think it's a combination of 2 factors: the developer and collodion combination I use seem to be extremely...
It didn't hurt too bad, actually. It had been sitting on the shelf at the store for years so I was able to bargain them down to $80. For that, I got the lens, lensboard, and a near mint #6 Packard...
Well, end of this project :(
There was no way the front lens could come out the back of the cell, so that inner ring had to be a retaining ring. I threw everything I had at it. Heat, cold,...
Youtube still seems broken but I uploaded it to Gfycat:

Took me a while to get back to this.

In my older B&L Tessar, that's exactly how it opens up and how I was able to clean the haze out of it. This newer one is constructed differently. The barrel is a single piece from front to back....
I have been trying with the rubber "lens wrench" cones and no luck. I'm twisting the hell out of it but the cone eventually just squeaks across the metal ring. I think the deeper marks in the...
I bought a Bausch and Lomb Tessar Ic today that I hope turns out to be a good deal in the end. The lens was hazy but my experience with previous B&L Tessars is that I could easily open them and clean...
Huh, that's pretty cool. It reminds me of a Type 69 emulsion transfer. What's the base emulsion for your process?
I used to turn Subarus into race cars professionally and diffs are a big part of that.
The "normal" differential in a car is an open diff. That means the differential splits the torque equally to...
I have an additional question.
I looked up the Cooke Triplet since I'd heard of it but I'm not familiar with it. The reference materials all show the Cooke design having a front element, a large...
If it turns out to be a decently well figured example of the formula, what should I expect from it? Coverage? And weirdness like a petzval? Some of this I can test out myself once I get another...
I *think* the rear group only has one element in it but it's hard to be sure. Here's the rear group shot from the front/inside:

I took a risk and bought a bigger lens on eBay. I'm hoping you guys can help me figure out what optical formula of lens it is. I have no experience trying to decipher this from looking at a lens so I...
Thanks guys. Sounds like the next step (probably tomorrow afternoon) is to remove the current GG and Fresnel and see if the fresnel fits into the recess properly. It's pretty clearly all been messed...
Title sums it up. I traded for what's turning out to be a basket case of a camera and I'm trying to get it sorted out right. On the Graflex Graphic View II, did the original fresnel belong on the...
The amount of UV sensitivity wet plate has depends on the salts you use but the UV response is never what I would call significant. It's a common misconception. If you look at the work Lund has done...
Your slow exposure is just as much made of lies and a complete fake as a shot made with strobes and nothing else. You're barking up the wrong semantic tree.
Can you provide any more info on this lens? I quite like the way that was rendered and I would like to try to find one for myself.

Using UVP-X and the B&S developer 1:3 (though for half the time they suggest), I have gotten as low as 160Ws with no additional sources of light. Just depends on what you're illuminating, how you're...
A googling didn't turn up much. Can you provide some info on whom you're talking about and in what country they're doing business?

I encountered a Graflex 1234 holder for 4x5 film and have loved using it to hold crazy things to put behind a lens. Was there ever something similar made in 5x7 or 8x10? Basically, some sort of film...

Drew, I hope your release of the 4x5 goes well. I'd be very interested if you produced a 5x7 and/or 8x10 camera in the future as it's not too hard to find a cheap, functional used 4x5 camera but...

Thank you. So, to me, I post screen-filling shots on my laptop. I've lately found out that they look tiny to everyone who doesn't still use a 10-year-old MacBook Pro because 1,000 pixels on the long...
2 sheets total, or 2 per side (4 total). 2 total is a bummer, 2 per side is sort of a bummer but if they're more secure than processing them 4 at a time in the Jobo 2830 tank, maybe it's still worth...
David, did you ever get better results with a different developer or agitation scheme?
