I have come to appreciate this fine enlarger after using it in a temporary/bathroom darkroom in my seasonal home in Florida. It has the simplicity and functionality that makes printing more fun. I have owned several other enlargers including the Beseler 45 MXT and the B22 is easier to use. I don’t think it gets the respect it deserves maybe because thousands were made and they were very common in the 60’s and 70’s. I think the photo community started to regard it as a toy or a little too amateurish to be taken seriously. Think about though…it is essentially a scaled down version of the Omega D series. It is often compared to the Besler 23 which is a good enlarger but is much larger and heavier. I use to own one and I find the B22 is is far better especially for a small darkroom. The Beseler has the edge for a larger format, 2 1/4” x 3 1/4” as the B22 is limited to the largest format of 2 ¼” x 2 ¼”.

I have tried to think how I would improve the B22 but for the life of me I could not come with anything…it just works for me. I will say that in Florida I tend to limit myself to smaller prints and seldom go beyond 8” X 10”. It can go bigger if you are so inclined.

The following is my notes and observations of the standard version of the B22. The XL version is much longer in the column and baseboard but a lot of my notes will apply to that version as well. Hopefully this will be of some value to those who wish to try “old school” photographic printing. The KHB site has a write up and list of parts and accessories:

B22 Notes


Medium format 2 ¼” X 2 ¼” and smaller sized film formats.



Manufactured in Woodside NY by Simmon Brothers Omega, introduced in 1962 and discontinued in 1974.

Dual condenser enlarger with option of 3rd supplemental condenser for 35mm format.

For Black and White films primarily.


Triangular aluminum column with counterbalance spring typical of Omega enlargers of that era. It is essentially a scaled down version of an Omega D2 without the dual I-beam column.


Baseboard: 16” X 20” (XL version is 18” X 26”)

Column Height: 37” (XL version is 49”)

Weight: Standard version approximately 16 lbs. XL version is 19 lbs.

Florida enlarger is set up with a Unicolor 760 Timer, a lamp foot dimmer (Set at 2/3’s light output), and a foot switch. It all rests on a Walmart Tool cart that is easily stored in a large closet and is easily moved to the bathroom…wheel(s) must be locked for stability.

Set Up:

1. Assembling is quite easy because of its size and light weight. 3 knurled screws secure the column to the baseboard with head locked on top. Those are hard steel and can be locked down tight. Some screws on the enlarger are soft aluminum so never over tighten.


2. Before attaching the condenser housing to the column, with freshly clean hands, insert condensers( 3 ½”) in the cylindrical housing (with attached lift lever ) by tilting cylinder with 1st condenser facing flat side down…orient as necessary with fingers. Lay cylinder upright with handle hang out over the table, insert collar so that it stays at the top and insert 2nd condenser with flat side up and is squarely on the three protrusions… lower the collar/condenser gently and make sure to orient so that all is even. During this process use blower to get dust out. If the supplemental 35mm condenser is used, remove filter drawer first, then lay it on top of the top condenser, flat side down and the two protrusions stick up (for removal). Make sure it lies flat and not interfered with one of the collars protrusions. Inspect for finger prints, especially on bottom condenser. Note: condensers must be very clean and scratch free or it will show up on the print.



3. Attach condenser housing ,with lift handle, to the two larger sized knurled screws on each side making sure the pivot groves of the lift handle are centered ( involves some jiggling) over the broader part of the knurled screws and that the lift handle works with no resistance once the knurled screws are tightened.


4. Alignment of Omega enlargers can be found here: http://www.jollinger.com/photo/cam-coll/manuals/enlargers/omega/Tech Service Manual - Various.pdf


5. Alignment is easy too but a Philips screwdriver and level is required…follow guidelines in Omega maintenance manual in PDF file. This will also minimize stray light as well. Pay attention to the lens stage because if the lens mounting is improperly installed, it can lead to problems.



6. After alignment, the condenser housing can be centered if necessary. One method is to have the housing empty of condensers…attach as above…insert a 2 ¼” negative carrier and look down from the top. Loosen 2 screws with screwdriver on each side on the pivot arms… let the condenser housing fall freely on the carrier centering by eye as you do this making sure there is no shadows on either corner…check for light leakage and then tighten the 4 screws…test again for leakage after condensers installed and adjust accordingly(there will be a tiny amount of leakage at best.) Alternative method #2 (and perhaps a bit easier) is to turn on enlarger with condensers in the housing. Focus on a negative first so all outlines are sharp. Remove the negative carrier with negative and center the white light in the housing so that all four dark corners appear even.



7. Attach lamphouse with PH111a, 75 watt, bulb with small knurled set screws on each side.



8. Bulb can be oriented to produce the most even light by loosening two plastic covered screws on lamphouse.


Lenses are attached to lens disc via jam nuts are directly screwed in and each disc has various sized holes depending on which lens is used. The discs are attached via 2 knurled screws and twisted in slightly and screws tightened snugly (do not over stress aluminum screws as the can strip).

1. Lamphouse can be lifted with clever lift handle on left side that secures itself on a knob so that negative carriers can be inserted and film can be oriented.


2. There are two main glassless negative carriers, 2 ¼” X 2 ¼” and 35 mm. I do have a 110 carrier as well. The most recent version is black on top and aluminum on bottom with spring hinge…this works very well. The older versions are all aluminum and no spring in its hinge.


3. Negative glassless carriers can easily be inserted with lamphouse lifted and the carriers are aligned with pins in the back although the older versions require a little more care in setting against the pins and should be checked after lift handle sets down the condenser housing. The older 35mm carrier is inserted with the 4 prongs up. Note: Cannot rotate the negative carriers.

Older and newer versions of negative carriers


1. Focusing is friction type moving the lens stage up and down with round handle…there is a long bellows.



2. Condenser/lamphead can easily be moved up and down the column by loosening a large aluminum knurled Lock knob on right side. Recommend not to put much stress on the lock knob…can raise or lower head by grabbing frame instead of knob. Spring strap can be lubricated with a light coat of Vaseline.




3. An optional 3” supplemental condenser is used for 35mm with a 50mm lens (not necessary if using a 75/80mm lens). Lamphouse needs to be removed by loosening the small knurled screws on the sides, filter drawer removed, and supplemental lens is inserted with flat side down on top of the existing condenser set…the prongs stick up and assist in handling without touching the glass. This is necessary for better light concentration for 35mm or smaller formats and shorter exposure time. This procedure is very easy and takes about a minute. When switching formats remember whether to add or remove the supplemental condenser.

Filter drawer is above condensers and comes in two parts…not as convenient as below lens filters. The 2nd part (top), a tiny metal frame, is probably not necessary especially for correctly sized variable contrast filters. To remove, it requires a slight lift before pulling out and insertion requires putting it in gently and lowering it into a grove to set in properly. The below lens filter holder swings out of way and filters can easily be inserted if sized appropriately. Originally meant for red filter. Works well for variable contrast filters (Ilford MG). Filters must be clean and with no scratches.

1. Use of light dimmer or rheostat is practical to reduce light output for modern photographic paper. Current floor/foot dimmer is set at 3 bars on slide switch which is approximately 92 volts…approximately 2/3’s light output. Heat is reduced too but never had any problem with negative buckling before reduction. May increase bulb life as well. There does not appear to be any negative consequences in using variable contrast filters as long as everything remains constant.


2. For extreme enlargements, the column can be turned around to project on the floor.





3. B-22 can be broken down and store easily in a closet. Column will need to stand upright with head locked tight. Remaining hardware can be stored in a small to medium sized box. Make sure all knobs and knurled screws are tight so they do not get lost but never over tighten.


4. Note: When enlarger is used on the Tool cart, make sure that the wheel(s) are locked to minimize vibration and movement.



5. Wonderful small enlarger…it has everything you need for Black and White photography. Simplicity in form and function…very user friendly. All functions work flawlessly and smoothly. Optional accessories and spare parts are readily available at reasonable costs because so many were made and are still plentiful. The only negative is that, because it is a condenser enlarger, that dust specks may be more visible in the final print.

Well organized presentation!
A minor note, from what I read elsewhere here on the forum: feeding the bulb lower voltage may affect its output with regards to the quality of the light produced, leading to undesirable effects on prints. To be confirmed by our local experts??

I have had a B22XL since the early 70's in school. All the things the OP said, including a planar adjustable negative stage, unlike the Beseler 23, which by comparison, at least at the time, was rickety.
It's well machined and a pleasure to use. I used it and moved it (easy to move whenever I did) till sometime in the 80's, when I acquired a 4x5 view camera, a used D2, and an Aristo cold light head.
I still see them on Craigslist for around 100usd with a lens.
I finally gave mine last year to my alma mater, a group of students working in analog photography.

I printed 2 high school yearbooks and everything else for years on a B22. Couldn't stand the D2s so I went to Beseler for 4X5 but I like the B22, it was my first enlarger.

Very nice enlarger. I've had a B-22 since the 1970's (mine has the unpainted aluminum column). The best upgrade I've done was to add a Chromega B colorhead, which 1) makes using variable contrast paper easier, and, far more importantly in my view, 2) substitutes a diffusion light source for the condenser one, which I find to be better for my work. The Chromega heads are available used fairly cheaply, and there's an outfit in Canada which restores and upgrades the heads to use a later bulb, so you don't need the external power supply of the original version.

I made thousands of prints with a B-22 XL. It was my favorite enlarger among several others used at various times. It's only shortcomings were the hot lamp housing and the possibility of getting out of alignment. However, the alignment could be corrected by screw adjustments instead of shimming negative holders and perhaps other places as required in some other enlargers. Reducing lamp voltage for everything except actual paper exposure kept the lamp housing cooler.

Making this a personal sticky.

While I’ve used Beselers, the B22 is my first personally owned enlarger. I can agree that it is a simple, elegant enlarger. Although officially spec’ed out at 6x6, I print 6x7 with just the slight inconvenience of sometimes having to burn one or two corners.

Not having much background in darkroom work, I’m still a little unsure how best to align and maintain this enlarger, so your diligence in presenting this information is greatly appreciated!

My thanks to Dan0001 for the excellent write-up. I’ve acquired a B22XL and though I’ve yet to use it it’s a beautiful, stylish design to my eyes.

Also I’d like to thank you for the idea of using a rolling cart. In anticipation of setting up a darkroom in my tiny shop I sold a mediocre old Craftsman bandsaw, thinking I would put a table in its place. Seeing Dan’s use of a cart to hold his B22 sent me straight to Craigslist, and I found a filthy, rusty Craftsman rolling tool chest. It looked terrible, but as the realtors say, “she has good bones!” Exactly one full can of Rustoleum Professional Glossy Black enamel later, if you stand back far enough and squint a bit she passes!

The top of the cart has a lip around three sides to retain a machinists tool chest. I had picked out some nice, reused maple plywood that I was going to rip to size, laminate and refinish to create a top in case I wanted to print with the enlarger on the cart. On a whim I took the baseboard of my B22 XL and dropped it onto the cart - a perfect fit!

A week after painting it still reeks a bit, but I’m very happy with the cart. It’s old-school, made in the 1970’s/early 1980’s when Craftsman tools were often very good. It’s made of heavy gauge steel with strong, solid drawers and runners and probably weighs 50 pounds empty. I need to winnow the equipment

a bit, but so far it fits everything except film processing tanks and measuring graduates/storage containers, and of course process chemicals, which I’ll store in plastic bins.

Congrats! I'm jealous. Looks very stable. When I'm working in the darkroom I put my photo paper in the top drawer...makes it very convenient. Lock the wheels as best you can to reduce any vibration.

The upside to a heavy old tool chest is that it IS stable! The third drawer down is a bit deeper than the first two, so that’s where I’ll put the paper. I’ve picked up two old-school plastic paper safes and they’ll both fit in that drawer.

This is a very nice shoutout to the rugged B-22. A lot of thought was put into how to set up a DR in temp location. The description of the equipment is excellent. I made thousands of prints with the B-22. I currently use a Leitz Valoy 2.
