Try xray film...full speed is about 200 iso and half speed is 100 . a 100 sheet box of 8x10 is about $35. That cuts down to 400 sheets of 4x5. Check the specs as most is red light safe but some is...

For low cost of dev look at obsidian aqua. 250 grams of pyrocatechol at $26 US will dev 1000 rolls. You will need 20 grams of sodium metabisulfite and about 1.6kilos of wash soda

Dichroic filters made from glass do fade over time. I used to manage 1 hour labs and bulbs burning 10 hours a day will fade dichros over say 5 years. Now, you have an enlarger not on constant burn so...

If the holes are numerous get some 420 denier black nylon packcloth and reline the inside. Fashion it into an oversize tube using contact cement and glue it top & bottom...spot glue it on the sides....

So far so good. shared some with friends and everyone's film is coming out

I bought 2 kilos of pyrocatechol from China at 1/2 price including shipping . That makes enough obsidian aqua to develop 16,000 rolls of film. Rodinal can be made with tylenol, sodium hydroxide (lye...

I'm wondering now if this repalcement bellows will fit--found this ad on ebay for new bellows and the 45g has 2 sizes a type A & B from the vendor. Type A which looks like my current bellows is 160mm...

To me, in looking at it closely, the flange with the screws is part of the overall casting of the rear standard--it does not come off--I do not see a seam. Granted, I'm a noob when it comes to large...

Thanks for the reply Kumar. In looking at the unit then, those small tiny screws only hold the bezel pieces together to sandwich the lip of the bellows between them. I took them all off and the...

Thanks Michael,
Before I go slicing & dicing I'll scope it all out. My existing frame is a series of small screws about 3-4 per edge on all 4 sides. The replacement one has far fewer screws per edge...

Hello folks,
I've lucked into a toyo 45d that was sitting around for years unused. In the inspection process I have discovered that the bellows are just a sieve of hundreds if not thousands of tiny...

Lens & shutter arrived today and indeed it will work with a flat lensboard--I made a temporary one from cardboard and it works fine

Yes, with my 88mm lens & the flat lens board the only way it would focus was to have it "parked" with the standards fully drawn in as if I was going to store it. Then that improved with the recessed...

I've seen some other postings just now in other forums where the lens is preferred for macro use as they were used in polaroid copy cameras and will cover 4x5--I'll know for sure tomorrow when it...

Thanks everyone for the responses. I have both a flat & recessed board as it is so it's a simple matter of needing to experiment with each. I was hoping for an imperical answer of yes- you do/don't...

Hello everyone,
While I'm no stranger to film photography I'm a newcomer to large format. I recently acquired a Calumet monorail (22" span) and I'm acquiring lenses and gear. The camera came with a...
