Beseler enlarger bulb

Remember Me? Page 2 of 4 First 1 2 3 4 Last Jump to page: Results 11 to 20 of Thread: UV bulb in enlarger? Re: UV bulb in enlarger? When I was at RIT in the s, I remember a professor and a few students attempted to construct an enlarger to use for alternative processes. They had the funds, and access to more equipment and technical expertise than most probably anyone of us could even wish for.

Plus downstairs was a whole printing department who daily used high intensity UV light sources. I believe that the project was short lived for various technical reasons and problems. I try to encourage experimentation even now in post post post post foto.

I only exposed for an hour and got a bit of an image on albumen. It does seem it would work with time. UV enlargers have been commercially made. There are certain problems with bulbs bright enough to do the job quickly. There will be a lot of heat, potentially requiring a water jacket cooling system around the enlarger head. All the internal seals and gaskets have to be high-temp pure silicone, or the extreme UV will break them down rather quickly.

And third, you have to protect your eyes with something like welding goggles. Sunburn risk too. It would be better to have a second, more ordinary bulb in place just for sake of focusing. The proprietary Fresson process uses a carbon-arc enlarger, a very old-fashioned option. Azo can be done with any reasonably strong halogen colorhead and a fast lens. See some of the older posts on this thread. As I recall, Jens did build his own prototype UV enlarger and put it up for sale, but ran into some legal issues safety-wise; it probably needed an automatic shroud to protect the operator from the light.

I set a timer for all of my UV work and leave the darkroom during the exposure.I've been using Omega enlargers for most of my life but I need a second enlarger so I'm considering the Beseler -- just for something different. I'm a little confused about the differences between the various Beseler 45's and two days of Google searching has only made me more so.

Can someone please provide a little Beseler ? What are the designations for the color heads and did Beseler make a VC head? In advance, thanks for your help!

Try getting a CB7, best enlarger I've ever had, sturdy as hell, adjustable, and you can focus and raise the enlarger up and down from the baseboard. Extra-large condensers and you can get cold-light as well as point-source heads for them.

I've used a number of enlargers in my life, from Omegas which I found not as sturdy unless wall mounted and cross-braced to Pako, Durst and others.

If you aren't going to go larger than 4x5, the CB7 is he nicest enlarger I have ever used. And they do accept the Beseler color heads as well.

I am no expert but I have 3 Beseler enlargers. The VXL is the largest, most solid enlarger. The center column is huge and heavy. If you have low ceilings, it can create a problem because the column is about 5 feet long. It is my favorite one but is a beast and I need a second person to lift it. The 45MXT is the other one. It has the U-shaped design and is smaller.

In some ways, it is more "alignable" than the VXL but it is a pain and the instructions were written by a sadist with bad English.

It has a motorized carriage to move the lens stage and light source up and down, but the usual manual focus.

It was designed to fit their enlarging table which allows you to remove the baseboard and place it in slots that are closer to the floor for larger enlargements. I believe that the chassis and light source can be rotated 90 degrees for projection on the wall, but I have not tried this and don't know how well it retains alignment in that position.There was a pretty neat set up for sale on Ebay so i picked it up. The enlarger i purchased was the Beseler 23CII.

Accepts sturdy, spring-loaded, aluminum alloy negative carriers that can be revolved for precise image positioning, as well as accepting the Beseler Rapid-shift 35mm and Nega-trans film carriers Snap-in, quick change metal lens boards, with a swing-out below-the-lens accessory holder I need to buy a lens for this enlarger. Which one is the best to use for 35MM? What tips do you suggest to get the most out of this equipment? Thank you in advance! Just dial all color knobs to zero.

Does it have a lens? If not for 35mm you need a 50mm. I am very happy with my El Nikkor 50mm 2. Looks like you got a great package and hopefully at a good price. Thank you so much!

I also wanted to know if i can manipulate the contrast on this enlarger. The enlarger in my class allowed me to that.

You can use the yellow filter to lower contrast and the magenta filter to increase contrast. Most variable contrast paper instruction sheets will tell you how much yellow or magenta to use to emulate normal, low or high contrast. AJGMay 15, Congratulations on your new Beseler enlarger!

Enlargers - All you need to know

As you can see from fleabay, there are MANY accessories available--ranging from heads, to negative carriers, and other accessories. Of the latter, you are good through medium format and every odd thing below that. The two standard lenses are 50mm for 35mm as noted by Craigand 80mm for medium format.

Beseler 23CII-XL Instruction Manual

As to lenses, in my opinion there are only three brands you really need to pay attention to. In the latter for a beginner, my suggestion is the more economical S in the Rodenstock if considering that make. They have served perfectly for over 15 years now--and both were purchased on fleabay. The thing to watch for in buying a used lens is clarity. Often enlargers were stuffed away in closets and garages after the photographer lost interest or jumped to digital--in less than optimal conditions.

Your lens should be free of fungus, and watch that the cement for the lens elements has not begun separating on the edges.A rack and pinion carriage elevation system provides exceptionally smooth magnification adjustments while the positive locking mechanism assures that magnification settings do not shift during the focus exposure.

The modular design includes a number of system features. These features include more precise alignment of the negative and lens stages for greater optical performance, a tilting projection assembly for wall projections, a distortion correcting lens stage, a below the lens filter holder which accommodates variable contrast or special filters, and a smooth friction drive focus assembly which allows for left or right handed control.

The 45 MXT motorized chassis provides a sturdy foundation for this enlarging system. The 45 V-XL sets the standard for professional laboratory use offering faster operation, greater productivity, increased efficiency, and unprecedented versatility in a large format enlarger. Its massive twin E-Channel with center-braced and vertical column assures that the center of the projected image remains stationary when changing image magnification.

Thus, there is no need to reposition the enlarging easel, especially important with roll easel users. The extra long column permits enlargements greater than 24x on the baseboard from 35mm film with a 50mm lens. The 45V-XL accepts the Beseler 3 lens turret, all the 45 series light sources and lensboards, and film carriers.

A built in swivel allows the projection assembly to rotate making wall projection easy. Additional features include an improved rack and pinion elevation control with locking mechanisms, right and left hand focusing controls, elevation reference scale and below the lens filter holder. These enlargers are a fine example of the extra measure of craftsmanship and performance which have characterized Beseler products for over years. The reversible column allows for floor projection and larger magnifications.

The column features a counter-balanced elevation control as well as an elevation scale for speedy printing size. The Printmaker now performs better than ever. Additional features include a focus knob, which can be attached for either left or right handed use, a built in elevation scale, and a below the lens filter holder.Please spread the word, both here on Reddit in related photography subreddits and also in your social media.

Beseler 23CII Enlarger set up self. I thought i was able to set it up myself but the package came with components that i have never seen before and i have no idea where to start. Any inputs, tips, or guidance will be greatly appreciated. I shoot 35mm film on a Canon A What other equipment i. Where do i begin? The 23C series enlargers are excellent! I had two myself, but gave one to a family member.

The other will never leave my darkroom.

You have a a good color setup there. The stabilizer box goes between the enlarger head and the timer.

The timer goes into the wall. The safelight goes into the safelight plug on the timer. The timer, when set to focus or running, will turn off the safelight and run the enlarger. Otherwise, it only runs the safelight. In fact, you can dial in variable contrast settings for VC paper instead of using gelatin filters. There are tons of books out there about developing and printing. Finally - that enlarging lens should be fine.The Charles Beseler company began in making scientific and lab equipment, and began producing enlargers in Beseler is one of the two dominant manufacturers in the USA.

Their enlargers along with Omega were frequently found in schools and rental labs; a great many students learned how to print on a Beseler enlarger. While not the least expensive, they are typically rugged, no-nonsense machines that are built to last. Beseler has a naming scheme for most of their enlargers which describes the features of the machine. I have a few of Instruction Manuals and brochures available for download.

The 45 series was Beseler's flagship for decades. The "ladder" chassis design was unique and identifiable. They were big, sturdy and well made, and were a favorite along with Omega of schools.

The following appeared in the now-defunct Modern Photography magazine, April It was written by Myron Matzkin. Negative size : 16mm to 4x5.

Focusing : Autofocusing by parallelogram, wheel and cam system. Light source: watt opal lamp. Construction : Steel and extruded aluminum with pyramid structure and obelisk frame.

Other features: Single set of condensers for all lenses, concealed counterbalance for crank-controlled up and down movement, horizontal projection, glassless negative carriers and wheel-mounted variable contrast paper filters. So we walked into the darkroom and there was this Beseler 45AF enlarger looking as solid and substantial as the Gantry cranes used for space rockets.

And then followed several pleasant days of print making in an attempt to test the Beseler on a strictly practical basis. The various frustrations that a wide variety of negatives can sneak into a darkroom bring out faults and virtues as no amount of dry run testing can.

We soon discovered that the appearance of strength and solidity engendered by the Beseler is real.

In a darkroom close by a studio used for various other Modern Tests, a few doors that open and close regularly, and surrounded by other vibration causing operations, the Beseler proved amazingly solid.

But the autofocusing mechanism in the Beseler is the feature that makes enlarging easier--and more enjoyable. A wheel mounted on an axle supported by two parallel arms fitted to the lower lens bellows rides on a long cam.

Once focused the lens remains focused for the negative no matter what change is made in the print size. As the wheel rides up and down the cam, the parallel arms raise and lower the lens stage, changing the distance between lens and negative, keeping the lens in focus for all enlargements.

And if you can't get a large enough print the normal way, it takes only a few seconds to loosen two screws behind the lens stage and swing the entire enlarger into position for horizontal projection. One set of condensers does the job for all enlarging from 16mm to 4x5 with 50, 90, and mm lenses.

Cams, however, must be changed for each lens if you want to use the autofocus feature. Position of the condensers is changed to match the lens in use.

Indicators on the frame show correct position for the condensers for each frame. If we have a criticism of the Beseler it has to do with the negative carrier. We found that the small amount of play in the negative stage makes it possible to move the carrier sufficiently to change the corner to corner position of the image on the enlarging easel.The Charles Beseler Company was founded in as a manufacturer of a variety of products including inhalers, magic lanterns with oil lamps and stereopticons.

By the company had become an innovative audio-visual company serving the military and education markets. InBeseler entered the amateur and professional photography fields with the development of the 45 Series Enlarger and other darkroom products.
