View Full Version : Choosing an 8x10 film

I am looking for advice on choosing an 8x10 B&W film to standardize on.

Currently I have two boxes of Tri-X 320, my first two boxes of 8x10 film. I have used this film for some time, in smaller formats. Now, I am a bit concerned about future availability of this particular emulsion. (we can avoid the discussion of why I am concerned, but I expect it to be discontinued in the near future).

Normally, that would mean filling my freezer.

In this case, I am using a different process to develop 8x10 film from smaller formats, which means I am not wedded as much to the film of choice for those formats.

Would it be advisable to use something like Ilford FP4 as my go-to film for 8x10? How well does this film work with Rodinal at various concentrations? Is Efke PL 100 a better choice? (I have heard that HP5+ does not work well with low concentration rodinal) How about PMK?

I am not particularly interested in T-Max, nor Delta. I want to start with something that is fairly economical, and makes good quality negatives for contact printing. I have the intention of attempting some alternative processes using these negatives as a starting point, but no real firm goals at this point.

My 8x10 film is Tmax400. Some of my favorite subjects include moving water and Tmax 400 has the speed to capture moving water so it doesn't look like cotton candy. However, if Tmax400 were to disappear, I would look to FP-4.

Oh no, please don't even mention that :eek:

Another suggestion for a nice 8x10 film is the Foma 100 and 200. The 200 is reformulated so no one really knows how the new version will perform but the old Foma 200 was excelent for alternative processes.

Well, the good news is that there has been no word about T-Max going away.

I might as well go with the Ilford. If they go away, there will be a serious hole in the paper market, anyway.

By the way, I would think that the shutter speed would be the limit on 8x10. My (copal-3) shutter only goes to 1/125. What would a typical exposure be, for you?

Depend on what your subjects are. I have never used anything faster than 1/25 on 8x10
most often my exposures are in the 8 sec. to 1/8 sec. If you need any Dof on 8x10 you need to stop down quite a bit and will get slow shutter speed as a result. 1/125 is not going to be a problem.

I actually used 1/4 second today with my 8x10 today and that was with a yellow filter-- most unusual for me -- but then so was using only f22. Normally, I use the B or T setting.

Ilford FP4+ is a wonderful film. Nice inherent contrast and all that...and through development I have been able to boost contrast for alternative processes. HP5+ on the other hand I have found to be dreadful for that purpose -- but I really need to give it a try with Kodak D-19 before giving it up altogether. But I am afraid someone will have to give me some before I use it again -- I won't buy it unless there is no FP4+, Tri-X or TMax400 available and need film ASAP.

I am going to give some ASA25 film a go for when I am photographing out in the open (usually I am in the deep forest) and I want to use some of my barrel lenses.

Been using mainly Foma 100 - some like it, some don't, but I've always been very happy with it (but then I don't need the speed, and usually use it at ~64 ISO also…)

I would use the fastest film if you are shooting at f65 or 45. That is because your shadows, as projected on the film, will be very very dim. Even if the film claims to have good reciprocity characteristics, you likely will be pushing things to the limit in your shadow areas.

If you are doing the 'wide open thing' then ignore the above.

Typical exposure can vary depending on subject and lighting. I was shooting wide open using either TMax 400 or HP5+, I forget which now, and needed to use an ND grad to bring the highlights back down to something the shutter could handle. I haven't developed these negatives yet, so I don't know how well they came out.

I have had issues similar with Tri-X and a 1/500 shutter. (The camera only went to f/22, though).

Just go with your first two boxes and don't worry about it.

With 8x10 I find that I really need to have some options.
TMY is a great all around film but it is very costly and only comes 10 sheets to a box (if there were any more sheets of TMY in a box and I'd need to sign a mortgage!)
Personally I think TMY is killing TXP. I love working with 8x10 TXP but it costs nearly the same as TMY with nowhere near TMYs bells and whistles.
Ilford films are fantastic---and much more affordable than Old Yeller. I have only used the conventional emulsions (I have a stack of holders loaded with HP-5+ waiting for some nocturnal fun!) and FP-4+ has amazing tonality, IMHO. If all there was was Ilford, I'd as fine as frog's hair with it. But I'm a substitute teacher these days and money (especially fun money) is tight. I rarely avail myself to Kodak or even Ilford these days and then only when a subject requires some extra goose which I know Old Yeller or the Great White emulsion has that will save the day (like nocturnal with photography)
My 'go to' 8x10 film these days is Arista .eduUltra, which is Fomapan, which does a wonderful job on 95%+ of the subjects I enjoy shooting---excellent tones and very forgiving unless reciprocity raises it's ugly head.
The important thing is to get to know your materials.
If TXP is working well for you and you feel like you're getting the best results you can, then do experiment with TMY or Ilford or Foma or any other emulsion that you think is interesting. Experimenting is fun! The sheet film market is volitile and one emulsion might be pulled off the market or replaced by another, or production might be stymied by some unforseen events (it has happened and no one manufacturer is immune!) So IMHO it is good to take the time to "learn" an alternative emulsion or two so you can keep shooting.
My 2-cents anyway.
