Yes that is what I said Drew. I believe the confusion comes from the fact that most people have experience with 35mm (or 120) SLRs or modern DSLRs and there are not center filters for those lenses...

No they don't, if we are talking about modern retrofocus designs. Sure, the 21mm Biogon for Contax 35mm rangefinder has the same basic fall-off characteristics of the 75mm Biogon on 4x5, but the...

I definitely get a variety of PM's and direct emails from "lurkers" or very low participation members about different things. I got a ton of emails after I organized a group buy (after closing it)...

Well, as an interesting data point, the forum says that:

Most users ever online was 12,386, 19-Oct-2020 at 20:31.

The most users ever were online just a few months ago, so that's an encouraging...

I have displayed plates mounted directly to wood. Including old barn wood that was most certainly not "archival" ;).

For protective purposes, I have mounted plexiglass over the plate using bolts...

1. Retrofocus design (SLR, due to mirror constraint) vs. non-retro ~symmetrical design (RF / LF) PS: they do have fall-off that is corrected by stopping down, due to mechanical vignetting, just like...

Dan, don't most modern wide-angles use the tilting pupil design? Glancing at a couple of my lenses, they all seem to have it to an extent (compared to my actual 75mm Biogon).

Of course they exist for a reason. And of course one should use them if they are really, really worried about even illumination.

Whilst I often shoot at f/22, or beyond, I also don't mind shooting...

Caleb, you were asking for part numbers and specifics.

Anyway, don't need to derail this any further.

LOL

Well the 12x20 certainly causes a new problem in that regard! Current solution: carrying the camera and one film holder inserted into the back in one hand, tripod in the other, rather small...

I'm afraid I'm not as selfless as Linus Torvalds. It does not benefit me to release complete design documentation. I also need to either learn or contract out software development and consider design...

It's just a light, you still need a negative or digital carrier system like I've designed. It doesn't display images.

Edit: I spent some time looking for spectrum information, and other data on...

Nearby there, I'll message you.

There's no need for that. IMO.

HMG, my design is using the original heads, so I can do color as well - at least in theory as I still haven't tested the actual workability of this. His solution is just an app for use on any device...

Hmm. Wish he lived somewhat close. With my little homebrew digital enlarger, some tweaking to his system, and a full-spectrum LED light I actually could build a complete digital enlarger system that...

Today I went out to a remote and not very well-known archaeological site, where a Native American settlement from around 1000 A.D. is located. There's a lot of mystery and rumors around this site,...

I like those.

Take Two in my backyard, no moon this time, but using the warmer I just got off Amazon. Just Orion rising, and a bit of play with tilt and a wider aperture. And most differently...my...

Agree with SergeyT.

It's one slider in Lightroom, if you choose to try it out. Of course as mentioned it also depends on movements applied, but you can also de-center it in Lightroom as well. I would say 20-30 seconds...

I'm well aware of the phenomenon, but for a long time I lived in south GA where it almost never got that cold to begin with. And it doesn't up here everyday either. Anyway, a heater thingy from...

Thanks for the info Kumar. I was referencing B&H's current listed price...interesting you could get one for 60% less.

I would consider a typical 240mm or 300mm f/5.6 and take another step forward. Maybe a Tele-Arton 270mm f/5.5 - I had one and it was really good wide-open - and you won't have the bellows extension...

Okay, good to know about the Wista lobes, my bad. I disagree about the rest of your points. Just look around here - many talk about how there's no perfect camera and therefore multiple cameras is the...

Please let me know how many folks are using movements or trying to shoot macro with handheld 4x5. Interchangeable magazine is a debatable point but plenty of folks are using standard film holders...

Some perspective: the two RF-coupled 4x5 cameras available right now cost about $9.900 (Wista RF) to $13,000 (Linhof Master Technika Classic). This is just the camera, no cams (or viewfinder on the...

Hear hear, Oren!

Let it go Bob!

There is nothing to modify with your account. If you can send money, you can receive money. Well, you'll have to attach a bank account, which I suppose you might not have yet if you've only been...

I always shoot these at f/22, in whatever configuration. And generally at infinity and without significant out of focus areas. I think the general consensus is that's the sweet-spot, which is only...

More CF confusion? Well you've already sprung for the big 82mm filter fast 90mm so 77mm filters won't work anyway. If you wanted to keep to 77mm an f/8 lens and less worrying about a small amount of...

Some Copal shutters have aperture scales that can be removed and replaced. Find one for a 210mm lens and you'll be "close enough" for most things. If you need extreme precision get one made or buy a...

4 1/2" x 17" is certainly an interesting size. Almost 1:4 ratio, 440mm IC needed. Oh and a camera/holder ;).

Your profile doesn't include a location. I suggest you add it - someone might contact you from here. *edit: just saw the above. Make them an offer?

I bought my first enlarger from a somewhat local...

Good luck getting most folks to send you checks / MO. Especially as a new member with no record or personal history on the site.

Yes. I also use the darkslide on occasion as a "GND" - if the exposure for the foreground is 2 seconds, I put the DS in front of half the lens for one second to get a 1-stop reduction in exposure in...

It's growing on me. Will have to look harder at the lens heater things they sell. Never needed one, before.

All of which are designs 50 years old, if not much more. But of course we have the usual bashing of products you'll never use or even see. Let's see what they come up with using modern manufacturing...

Wanted to try this. Setup a composition in my backyard and shot this over the course of 6 hours. When I went out to close the shutter though the temps had dropped much lower than expected and my lens...

30x40 inches? Always fun seeing such large prints. I like the play between car and house.

You can see my recent post in the Old Cars thread for a "cult" lens with extreme "out of focus" areas (f/2.5, plus tilts for less DOF). Like it or hate it, it exists, and one can choose to use these...
