Hi there,
I have some basic questions about the negative collodion process that I hope to get more info to answer them.
From what I understand, for the negative collodion process you need

Great book, nicely written and loads of detail!
Dear community!
I don't know it this is right sub forums, but please be aware if some of the items show up in the market!
The following largeformat photography equipment was stolen during a...

Actually a Rolleiflex is a great comparison! :-)

Thanks Garret, I won't polish the lens, but maybe the hood, I don't know yet. As a user first of all I need a flange for the lens :-)
Nice looking RR you got!
Thanks Steven and Garrett!
I've never seen such a black brass before but maybe both of you are right :-) We will never know. I just wanted to know if there is a chance that came from factory. Here...
Dear folks,
I came across a very unusual Voigtländer Petzval lens that dates back to 1852 (#4071). The lens is in great shape glasswise and it is big 16" focal length and fast (f3.8), but the lens...
I would love to see some sample shots.
Does anyone have a catalogue excerpt with coverage? I wonder how much the 400mm can cover...
Try to get a 16 or 19" dagor for landscapes...
For a full body portrait you can also look for a Dallmeyer RR, my 18x16 covers my 16x20 easily with wider opening than f/45. Maybe you can get...
Yeah quite old fashioned, maybe she is too old anyways? :)
Thanks guys for your help with that lens, as soon the temperatures rise I will test it!
Wow I did not know about the Pont et Princelle booklets, but it seems I don't have access to that one through libraries here unfortunately.
I just know about the wide angle hemispherique with the...
Hm there is nothing unusual in the waterhouse slot so I don't think there was a wheel. But anyhow maybe it was a custom order - or a budget one? What is a P et P booklet, Steve?
Hi all,
I came across an unusual Darlot Hemispherique (or wide angle hemispherical) No. 6 (16" FL) with serial number 999 that has not the typical levers but a waterhouse slot. It doesn't have a...
Dear Steven, thanks for your opinion. Well I noticed some differences in the catalogues, too. But what I can say is that the lens I tested has more of a 50mm opening with a focal length of ca. 46cm....
Ah this one is great Rob, thank you... Well 11x14 is too little but maybe stopped down it will work on 16x20", who knows.

Dear Folks,
I was offered a Voigtländer Euryscop IVa No. 5, about 46cm/f7 brass lens. I tested that one on a 40x50cm camera yesterday for the first time and it seemed that the lens covers the...
Mine is a IIE 15" f4.5 Knuckler S/N 221188
Yes the front and back lenses were very convex. One should be very careful when you lay the lens on a desk....
Here are some recovered (small) images from the auction, here you can see the...

This is a picture of the lens and it matches with the serial number on the images (that are now lost in the web) from the auction site. It doesn't have any specific naming on it...
Thanks Steven for this great information!
So your guess would be that Auzoux & Banz made a G&C-like globe lens? Well this could be a very nice lens indeed!
I really need to get hands on that lens...
Hi all,
I got the opportunity to buy this exact lens (Auzoux & Bauz).
Focal length is about 45cm (17") (from what i measured) but what I would like to know is if someone out there knows what...
Great pictures here... I've got one too:

Cooke 380mm f4.5 knucklers on 18x24cm
Yes it is a 40x50cm camera, you are right. The holder is not original but newer, I had to modify the fillet where the glass plate is positioned due there was a delta of about 3-4mm regarding the...
Recently I've built a stand for my 50x50cm ULF-Camera so now I can show off that big thing!
I think the camera was built around the 1900's, has an adjustable back for a little horizontal and...
Thanks for your responses!
It is a 40x50cm camera and it is very very rigid, no need to have a support for the front standard. The 8kg lens is doing great on that big standard:

Hey!
Yesterday I bought a camera for the lens, finally! Here is one picture of the camera... very big bellow's extension! :)
I'll post some scans of wetplates soon! :)
Thanks to your help and especially to Louis, I completed the repair of the Cooke lens.
The most difficult part was the removal of the hood and the inner soft focus barrel. Both parts were stuck...
Anyone with some information?
Well, I'd do the repair by myself, but I don't know exactly how.
You have to remove the whole front barrel in order to replace the screw in the inside of the barrel.

I wrote to SK Grimes. Maybe I'll find a repair service in Germany...
Hi everyone,
I have a 15" Cooke Portrait Lens of the series IIE with a broken screw that holds the knuckles. Has anyone ever repaired a loose brass knuckles of that type of lens?
Thanks in...
Hi everyone,
I did some research in the net, but did not find any info about that lens. The label says Aldis Triplet W↑D 20in. 5.6. What I know is that W↑D is for War Department.
Does anyone...
Thanks Brandon! As my budget is limited, I will try to build a camera with a friend, who is a carpenter. And what I am not sure, if the bellows extension of 1m is enough for this lens is enough for...
What a coincidence that the only pic around is from an astro photographer. The lens really looks like mine, I like that! Perhaps the engraving on my lens was added after the sale by Liesegang. Once I...
Thanks for your opinions and assessments.
Does anyone have a picture of a 6A? I would love to compare the lenses ;)
Despite of all what is right or wrong with that lens, I think it has an...
Got it from a friend who owned it for many years. He did some astronomic pictures with it and had it in his basement for years.
Thanks Steven! I measured the focal length and it is about 80cm, so 30" could be correct.
It can be that Liesegang bought a special order - as a potential concurence?! - maybe I can ask the if...
Hello everyone,
recently I picked up a Dallmeyer 6A lens. Since there is no info about that lens in the internet, I want to share some pictures with you.
