Question about filtering Efke 50

[Flotsam]

I'm going to be shooting some efke/adox 50 and would like to darken the sky. I understand that using a Red filter will affect my exposure due to the film's sensitivity. Does anyone have any information or experience using a Yellow or Orange filter with this film, or the 25 iso version of it?

Maybe I should just work with a polarizer.

Try a No. 15 Deep Yellow. You'll get a very creamy, neutral grey sky.

I would try 2 stops with a #15, 2 1/2 stops with a #21. I am not a user of this film so this is just a guess mon my part. Take an un filtered shot and a couple of shots using each filter and bracket. Keeps some notes and then come back and tell us what works.

Since both I believe are orthopanchromatic, I usually err on side of denser negative & add 3 stops of exposure for the orange filter. I'm still evaluating them vs Efke 100 for landscapes.

I like Efke 100 very much. It has a much more conventional Red response than the slower films.

I was very disappointed with efke 50, it seened as though it was just as grainy as the 100. It seems as though it is the same emulsion with a different set of sensitizing dyes(just a guess, no facts here).
Efke 25 is much much different.

Do consider getting a graduated red / yellow filter

I like the 50 a lot more, precisely because of the orthopanchromatic response.

I tried some filtering with both 25 and 50, and their response was similar. I liked the 25 better, however. But red filter was inconsistent with normal exposure, which was confusing.
I say a polarizing filter is a great idea. Yellow filter works, orange is OK, but requires quite a bit more exposure. Yellow gave me decent skies.
Personally I like the Efke 100 best of the three, but am so tuned in on FP4 that I don't experiment with it much anymore.

Efke 25 & 50, yellow. tim

I have photographs on Efke 50 with a yellow filter.
The sky and clouds I would describe as smooth and mellow. Quite pleasant but not the film for dramatic skies.

I have used Efke 50 120 almost exclusively in the studio where I have complete control over the the lighting ratios. I love it for its tone, grain and remarkably good reciprocity characteristics with long exposures. I have just scratched the surface of using Efke 50 in 35mm for general outdoor scenes, playing around with a few rolls that I added to a JandC order to qualify for free shipping.
I haven't critically compared grain but I feel that the first roll was a bit over developed so it probably wasn't a good indicator of the grain that it is capable of.
What I was very impressed with was the tonal range which was more docile than Pan F+. At it's full rated speed, the shadow detail was better and it had less tendency to block up the highlights even though I was shooting contrasty scenes and, as I said, was a bit long with my development.
I have a lot more experimenting to do but I am encouraged by what I've seen. I shot a couple of rolls yesterday, mainly sunny snow scenes and I have a couple of bodies currently loaded with it.

I should comment a little on my thoughts on efke 50... It is a great film for many things but if you are going to do landscape/tripod it didn't make sense for me to use it.

Is that because it will tend to lighten the sky?

 

[avandesande]

Just that the 25 is better (for this purpose)
One of these days I will get a scanner....

 

[Flotsam]

I get your point. 100 is a nice walking around film, 25 is great for a tripod. 50 is kind of a neither here nor there film.
Still, it shoots at 125th @ f/11 on a sunny day so, if it is noticably smoother than 100 or has a unique look, it's got a place in the camera bag.

50 is kind of a neither here nor there film.

Maybe so, but I love it for portraits. The orthopanchromatic response makes for lovely skin tones, far nicer in my opinion than R100. I've never shot portraits with R25 or PL25.

Let us remember that Ansel Adams made Moon and Half Dome on this film
