I would say 135mm better for lower magnification (1.5-3x) and 150mm better for higher magnification. This is because at lower magnifications the lens is farther from the film so both have similar...

Mono,

To deal with heat effects, replace tungsten with LED bulbs if possible.

Get some neutral density filters to lengthen exposure if needed to replace fractional seconds with even seconds.

I use one of these all the time for 4x5 using fuji hru and they work fine. Scratching of edges can happen when removing sheets from tank. Two solutions to this.

1. Have tank full of water. ...

That would have been a so-called enlarging camera for Daguerreotypes. Enlarging papers did not exist commercially until much later. I don't have the date, but it was after the wet collodian era...

I really thought this thread was a joke. The first posts related to it being a bot. I thought that was funny, and got a good laugh of of it. Back around 1973, I experimented with wet collodion...

I think you should try to develop a sense of humor and not take things so seriously.

I suggest putting a decent digital camera inside a box that appears to be an antique portrait camera, and tell everyone it's a wet plate. You could even use plates of glass any size you like and...

This is a large format forum, so we only talk about 4x5 or larger formats here. Yes, you can "start out" with a press camera costing far less than the most expensive enlargers. I don't believe...

I think I saw some published plans for a slide viewer in Popular Mechanics 50 years ago, maybe. I hope my answer is vague enough.

What I am wondering is if there are big differences in spectrums between these two kinds of orthochromatic films, aerographic and medical.
(as for developers, I typically use metol variants...

As someone else mentioned, these may be intended for using enlarging lenses on view cameras. There may be some 135-150mm enlarging lenses for 4x5 that will fit these threads. I have a 135mm...

It's not that simple. The 23c is a condenser enlarger, and the condensers are not large enough to cover 4x5. I used to have a 23c, but don't remember the details. You would need to remove the lamp...

i currently use my 4x5 speed graphic as a diffusion enlarger, and it work very well. I use a cheapo $10 usb diffusion pad as a light source. I use the focal plane shutter to control exposure time...

Mem,

I wonder how you will process this film. Tech Pan is a lot like a panchromatic version of ortho-litho film. It's very high contrast, and used a special developer, I believe the POTA formula...

It's likely aerial camera film, not a bulk loading film. It's on a very thin stock which will make it slip out of the film holders. Put a piece of construction paper, cut to just under 4x5 to make...

Yes, coat the printed surface only. Not tried selective toning yet, but it may be workable, depending on amount of bleeding. You would need to work fast before too much soaks into the paper. Also,...

Just did some more testing using dry prints instead of wet with even better results from staining, but requiring stronger tannic acid.

Fasten a dry classic cyanotype print down to a flat surface...

I've been experimenting with tannic acid toning of cyanotypes on the cheapest watercolor paper I can get at Walmart (Grumbacher), and finally have very good results. This method can also be used on...

However, you may consider getting an "ensmaller" to reduce those ULF negatives down to 8x10 or 4x5 for greater resolution than any mere contact print.

I like your response. Many are not aware that one of the main reasons for Adams zone system was to target a grade #2 paper for final printing, which required a method to meter and develop to match...

John,

I would DIY a panel using warm white LED strips, which are closer in color to tungsten lamps that those filters are designed for, then use VC filters that fit below the enlarging lens. All...

Drew,

Near UV behaves more like visual light with optics. Projector optics suppress near UV while enlarger optics have little effect. The 395nm uv leds have a fairly narrow band, but extend from...

That video is one of the best out there but very lengthy. He doesn't mention the frequency or size of the custom made LEDs he ordered from china, but they must be near uv (395nm) and pretty small,...

Hi John.

I looked into this a couple of years ago but scrapped it after a few experiments. If your OK with expoosure times of a few hours or maybe even a day, then it can be made to work OK using...

I was just on the B+H website and noticed they have the Inkpress Media Regency Royal Hard Dot Camera film available now in 8x10 for $40 per box of 50 sheets. This film is similar to the Arista Ortho...

Wow, a moderately old d23 thread!

D-23 is the only developer I use. I standardized on it about 35 years ago when I got tired of experimenting with developers. I use it 1:3 for all camera films,...

Yes, that's the only direction you can agitate, the same direction that the film is in. Agitating perpendicularly, the films make get knocked out of their slits. I don't think the person that wrote...

The only that I could standardize on filters was diy. I have a set of "theatrical gels" that I bought on Amazon for about $8.00 for 2 each of 8.5x11 all standard colors, which are saturated enough...

The manual is not very good, especially in the how to agitate department. Yes, you agitate in direction the film is, but I repeat that if any solution comes out, you are agitating way too strongly. ...

Dust on lens has no effect on photos. Dust on film before exposure, not much you can do other than try too bleach/spot negs or prints. Dust on film while wet and hanging to dry requires re-wetting...

[QUOTE=Melissen-Ghost;1676570]Hello everyone,

"Also Im not quite sure what the difference between the back standard tilt with the (using the black knobs) and asymmetrical tilt (grey metal knobs)...

I have the Doran tank that is identical to this one, with a paper manual. It has very fine print, will be hard to read with phone scan, but will try doing that in the next few days as time allows. ...

The watercolor paper I buy at my Walmart (Grumbacher) works very well for cyanotype witthout any pre-treatments using a 20-10 fac-pfc sensitizer, although probably not very archival since it is heavy...

I would suggest the following.

1. Get a large format camera of some kind, an old graphic 4x5 is a good choice.

2. Use the "taco method" to develop four sheets of 4x5 in your Patterson tank. ...

Looking for a way to get 11x14 green xray film. What does "tri fold"mean? Are these films creased and folded? In other words, do I get three pieces of film each 14" x 12" that are creased and...

Andy,

I suggest using the Foma/Arista EDU 200 rather than 400. It's also available as Frankenstein 200 at B+H in 4x5 only. This film has almost the same (many shoot it at 150, I use 200)...

There's a thread with about 20,000 entries in it in this category of this forum. I guess you missed that. Web searches will turn up results in this forum pretty regularly. HR-U processes like most...

Barry, I know you already have the distiller, so that has to work okay, be careful to not boil away all the water to make it easier to keep clean.
I installed a new water softener and then an RO...

Another 1950's TV show centered on photography was "The Bob Cummings Show" He played a glamour photographer in Hollywood, you can see the studio view cameras and model shoots often on that show. ...

Was scanning FreeVee for shows the other night and found this "Man with a Camera" show starring Charles Bronson in 1960-61 where he carried a 4x5 Graphic press camera around and takes pictures....
