12x20 enlarger lens suggestions

[wborders]

Hi Everyone,

I'm looking for an enlarger lens that I can use to double my 12x20 negative to get a 24x40 print. Specific recommendations would be very helpful.

Thanks

First, do you have an enlarger that can handle 12 X 20???

You can consider getting a light source for your camera back, and start with using the taking lens...

Figure about how much bellows extension/FL you will need for your enlargement size/ratio first...

A lot of other details also have to be answered...

So, no. I have a 4x5 enlarger. I have read the 20x24" Enlarger thread and know that there are LOTS of other details to answer. But, I have to start somewhere. hahaha. I've read that photo enlarging got its start with using the camera the picture was taken from, which in my case is a Folmer & Schwing and the lenses are Nikkor-M 450 f9 and a B&L 11x17 Tessar IIb.
Thanks!

if you look under "my lab"
you will see a GIANT enlarger he made to enlarge his 20x24 negatives

Thanks, John, I was fully unaware of Yanul. I sure missed the boat. Looking through links, I liked this eulogy.

"He was getting to a point in his life when he wanted to ensure that his work would be useful, that it would last," Glowacki said.

"He had a romantic view of life," Doctors said. "He thought history should be recorded."

He expressed the same thought to the Tribune in 1988. "I'm leaving my photographs behind. That's my legacy."

Mr. Yanul's wife, Natalia, died in 2010.

Services were held."

Chicago is still changing fast, teardown and new building proceed at an amazing pace. Hopefully, another visionary photographer is at work.

I for one miss the dark corners, even the marks of decay. One reason I left Chicago was the view from my front door changed. The city decided grey concrete was more interesting...and 1000 more apts were built right next to this new attraction. A converted train route.


My prefered Art for 13 years. The painted underpass was used almost every day for wedding shots, movies and photo student practice. The whole 3 miles were sand blasted to blankness and appeals to the Artist in Charge were fruitless.

14" was the largest commonly available enlarger from Saltzman, and DeVere. With the advent of high-power panel-type LED lighting, conversion of your camera to an enlarger can be quite viable. Especially if you built you camera, you know the back mechanics and could figure how to adapt the light source and make the negative carrier.

[William Whitaker]

Just a thought... Since your 12x20 is a Folmer, you may find the whole process to be complicated by the fact that the Folmer & Schwing banquet cameras do not have removable backs. You might be better off building from scratch.

Thanks everyone for your suggestions. Will Whitaker is right. The F&S does not have a removable back. However, between the link that Randy Moe sent and the Thomas Yanul darkroom pictures I have an idea of how to start.

Wow, 4x5 to 12x20 enlarging. Now that's a jump! Good luck!
