I’m embarrassed to say i’ll probably start on 4x5



Thankyou for taking the time to help show the algebra behind it, it will save me some time and misery no doubt as i plan the next phase.

Howdy all, i’ve got some big plans for a wet plate project, but Initially i plan to master the technique at the tiny size of only 4 x 5” ;)

Google has popped up with 4 main brands of plate holder...

Which I’m guessing is only going to give me 1:1?

My darkroom needs to be larger if I’m going to need to stretch out to infinity. I only have 4.5m (14ft) to play with.

Thankyou for the pm, the system will not allow a reply (mailbox quota).

So let’s pretend I’m an idiot with much to learn, focusing much closer than infinity, does the coverage increase or...

Very cool, Thank you.

Thankyou for the tip.

Thankyou, If it was easy and cheap everyone would be doing it.

I can’t explain my motivation, but this feels like the next step for my lifetime project which started on 35mm film 20 years ago and...

I may not have made it clear in the thread, apologies.

There will be no wall copying, the stretch goal is a tintype headshot at 40 x 50”.

The time may come where I have to accept that the...

How close to the lens can I place the subject and still achieve focus? Or a different question that’ll give me the answer I’m looking for, what is the maximum magnification with those lenses?

How long ago did you go to school? ;-)

Found this one from the late 1800’s

I just stumbled on this while researching apo-tessars, by a forum member Dr Klaus Schmitt, unfortunately all the focal lenses are too short, but an interesting resource none the less.

Good to know I’m not insane in my plan to turn part of my DR into a camera haha. I’d love a mobile setup like Ian Ruhter but while I learn the intricacies of the wet plate process I’ll settle for...

Hi All,

Long time listener first time poster (I think).

I’m looking at building a static camera in my dark room for 40x50” tintype. Searches have yielded me several options for that kind of...

Good luck!

Cutting it down isn't so bad given you can do it under the safe light though.

Taulen, have you tried contacting the Kodak/Fuji/Etc distributors for Norway and asking to speak to the medical sales reps? My contact is the normal photography rep, but he liaises with the medical...

All good, makes sense.

If i get my hands on any in those sizes i will let you know, i shoot 4x5 so cutting down is something i will always have to do with xray film. Maybe when i upgrade to 8x10 i...

Hi Bush,

I did a reasonably painless test to determine the correct ISO for my RX-U

I Took 8 exposures of the exact same thing, 2 sets of exposures at 50, 100, 200 & 400. Developed one set for 4...

Are you fussy about the size/type? I have a spare box of 100 sheets 28x30cm Fuji RX-U. Exposes pretty nice around 50ish ISO. I pick up samples or nearly expired stuff mostly random.

Are you familiar with the troubles and risks of shipping? i.e. the film being X-rayed in transit by the freight forwarder or operator?

I can source Fuji X-Ray film for cheap (I know the NZ...

Isn't the entire IR spectrum invisible to the human eye?

I just use my regular safe light, but I minimise the 'out of the box' time as it appears to cause very very minor exposure that is only...

So far I've been having a blast with xray film.

I will be setting me LF Enlarger up next week to try doing some 8x10s from 4x5's.

So far I have been inspecting the quality of the negatives by...

LC29 at 1:29, have lengthened the dev time to 4mins for 50ISO and 8mins for 400ISO With great results, the best at 50 i think. I ran out of 400 iso exposures to test the plane at 8mins, reshooting...

I'm completely new to both large format photography and X-ray film.

Have been experimenting with Fuji RX-U

My first 4 exposures were this plane at 50, 100, 200, & 400 ISO. I made the...
