Matter of fact, I'm salty now.
I've been mucking around with a 1938 Leica IIIa I was given. I've chucked the 50mm f2.8 Elmar from 1958 I bought for my IIIg originally, although I have a '49 Summitar which is now almost always mounted to it. These were taken on God's Own Film (Fomapan 100).





The other oddball I have is I recently acquired a Leica M1 - it's an M2 sans rangefinder. I'm not sold on the M over my screwmount Leicas for a stack of reasons (the RF telescope on the screwmounts are great), but I can get why the M has a real following. This was definitely shot on a roll of Fomapan 100, but I can't remember if this is on the f2.8 Elmar or the Jupiter-12.

First of all scanning is relaxing. Sure it takes time but it's an important part of the process. Unless you are printing it's likely the first time you really get to see your photos which to me is still magical. It's also when you get to decide what the final images will look like. It's a great opportunity to think about your photos and how they all fit together. Or to think about photography in general!

I’ve always wondered: how hard is it doing darkroom prints of colored negatives? I know how to do B&W, even if I haven’t for a while, and prints with enlargers but I’ve always been told color negative film was designed from
The ground up to be done via machines

It's a far more rigid process with less opportunity for creativity than black and white printing. Dodging and burning a colour print introduces colour shifts and you can't change contrast. The whole process has to be done in complete darkness (unless you have a very expensive safelight).

The process is essentially:

  1. set colour filtration to recommend for the film stock
  2. Do test strip to determine exposure time
  3. Do test print and assess using colour print viewer
  4. Dial in compensation on colour filtration head to remove colour cast
  5. Repeat 3 & 4 until colour casts are removed

For me the additional effort isn't worth it for the reduced artistic input. I'd rather scan and edit the few colour photos I take and get them printed with a nice inkjet.

I'm not sure yet, but i might sell my Osram Duka 10 low pressure sodium safelight. Sodium is the one you need for color paper.
*If* i am gonna sell it, the price will be 50 euro, willing to ship worldwide.
Works perfectly fine, and it is complete in its original box with user manual and stamped warranty form from 1985.
If anyone might be interested, let me know. Whether i actually will sell it, depends on some other stuff i'm trying to get rid of. My tech room is too full of interesting old electronics.

Even with the dedicated sodium safe light, you need to turn it all the way down for working with modern color paper, because the modern stuff is more sensitive than what they used when the safelight was new.

I would like to have fully analog color prints just for the sake of doing it without a computer, but i feel like i don't have the energy to get into yet another workflow. If i were to do it, i'd do it in a communal dark room so i can use the RA-4 processing machines.

Ok, I went to the place with the dark rooms that sells film to buy film and walked out with a professionally refurbished Yashica Mat 124G. All the cameras I inherited that are medium format take 620 film and I really just don't want to deal with that. I really need to find all my undeveloped film stash and send em over.

I just bought a iiif last month for myself. Shot my first roll of film and eagerly awaiting for it to get developed. What are the risk of light leaks on this camera? I have the older version of your lens, the Elmar is legendary though and what put Leica on the map.

Both of your pictures look great. Did you have to get a new rangefinder mirror on yours? I bought from KEH the initial one was rated “excellent” and the mirror was in terrible shape, they have a great exchange policy and sent me another one in great shape, bright mirror and I suspect it had been CLAed as it functions more smoothly.

Nice camera! I really rate these Barnacks are great user cameras so I don't think you can go wrong with them. The mechanism is extremely simple and really the number of these still kicking around is a real testament to how great they really are.

The risk of light leaks are really small - the primary issue will be shutter pinholes or something like that. Anything prior to the Leica IIIc will have some issues with light getting around the baffles if the lens is removed in strong light, but that'll be it. I had a really oddball light leak with my IIIg because some of the vulcanite had come away from between the slow speed dial and the lens mount, as well as from around the lens mount. I just used RTV silicone black to fill it in rather than re-covering the whole thing but that would've worked as well. The advantage of these bottom-loaders is theres just not a lot of ways light can get in.

I'll be getting a new mirror/optics clean on the IIIg in the next 12 months - it's not terrible but my IIIa absolutely smokes it regarding how nice the RF telescope is. The most annoying thing for me was doing the vertical alignment on the RF for the IIIg - there's not a lot of documentation as it's a bit more of an oddball Barnack but I ended up turning the prism with a toothpick and now it's awesome.

e: the biggest trick is loading, for sure. It took a few rolls to get "the touch" but now it's dead simple to get the roll, pull it so it's 22 sprocket holes long, cut a 20 sprocket hole leader, and then seating the film. It's to the point where I can change film in and out and not lose a frame as long as it's going into another Barnack.

Thanks. I'll have to check it against my DSLR results and see if it's close. I was way more comfortable with everything film, including trusting the camera light meters, when I was doing it regularly. I guess I'll still probably pick up a good modern incident light meter.

In the last thread I mentioned I wanted to see how different gammas of one film stock impact the resulting scans. I wanted to do this because (1) this article argues that Zone 8 density should be ~1.25 while my Zone 8 density is often ~2.0, and (2) I don't want to gently caress up some expired film I had recently picked up. The idea was to do two test rolls of Delta 100 where the only variable is developing time, characterize the film speed and gamma, and then do some actual subjects using another two rolls, so I can compare how different gammas impact scans of high dynamic range and low dynamic range scenes. I just finished the speed/gamma characterization and things are not going too well.

Methods:
I am using a light panel to create a uniformly lit surface, and I use my camera to shoot a "dose array": exposures from -5.5 stops to +5 stops, along with one blank witness frame so I can measure base + fog. The setup looks like:

I keep the aperture fixed and only adjust exposure time, making sure that +5 lands on 1 s.

Developing:
I use 12 mL Rodinal in 900 mL water (1+75) at 20 C for each roll of 120, and I use constant agitation in a Simma roller. On one roll I assumed ISO 100 and developed for 15 minutes, while on the other roll I assumed ISO 20 and developed for 10 minutes.
Stop: 45 mL IlfoStop in 900 mL water (1+20), 1 minute
Fix: 190 mL Ilford Rapid Fixer in 760 mL water (1+4), 5 minutes
Rinse: 4 times rinse/agitate/dump with tap water, two final rinses with water that was filtered and then distilled

Measuring:

The resulting roll is cut up into four strips, placed on the light panel, and I use my spot meter to measure how many stops darker the frames are relative to the blank witness frame. To eliminate ambient light, I place the light meter in physical contact with the film holder sheet and I put a cap on the eyepiece of the spot meter (though this last point only impacts the high density measurements). Stops are then converted to density in a spreadsheet.

Results:

The data are plotted. Film speed is determined as the place where I get a density of 0.10. So if I meter at ISO 100, and the -4 exposure gives me a density of 0.10, then the film is indeed ISO 100. But if I get a density of 0.10 at the -3.5 exposure (half a stop more light than expected), then the actual film speed is ISO 70 (half a stop slower than assumed).

Fudge factors:
My Sekonik can only use 1/3 stop increments in ISO, while my Hasselblad can only shoot in half stop time increments. If I don't have a frame with a density of 0.10, I have to make an educated guess. In the ISO 20 roll, I had to use the lens wide open which resulted in some vignetting.

Question:
I am not surprised that the roll that was developed for 15 minutes came out with a high gamma of >1. But I was hoping that the second roll would give me a gamma of 0.6. Unfortunately, it appears that if I insist on reaching that gamma by just adjusting develop time (nothing else) I would end up with a film speed of ~ISO 10, which is comically slow compared to half box speed. So, what is the easiest parameter to tune? I am thinking the constant agitation is the next thing to adjust. I had initially bought the Simma roller so I would get consistent results. I come from the photolithograthy world, where one either agitates constantly or not at all; anything in between will give inconsistent results. Since I don't like the results of stand developing, I decided on constant agitation. But if this locks in high Z8 densities I will try a roll with normal black and white developing.

On the bottom of a paterson tank there's written how much liquid you need to use. 290 milliliter per 135, 500ml per 120 in my case. I always add a tiny bit extra just to be sure...

My 2 reel tank says 500ml but I always put 600ml.
Once I had bubble shadows show up on my negs which was due to lowered volume in the tank because of a leak I assume. Switched to 600 and I've never had that issue before.

I checked the Yashica light meter against that phone app, and they both reported the same. I checked my Zeiss Bullseye against that app and the camera meter read a few stops low. I did some reading from a guy that repairs these cameras and apparently the meters are just awful in the context of modern film speeds and only really good with sub-100 ISO films. I think I used to use that meter, but I can't remember. I'll have to experiment with it once I'm developing my own film again.
