Rollei 35 S filter stacking

[Daniel Huiting]

Hi All! Just bought a Rollei 35 s and want to use it for infrared film photos, since it is
not TTL and I can actually see what I am framing. I am told that a polarizer in addition to the r72 filter is the best way to shoot infrared to get the deepest IR effects. I am wondering how many 30.5mm filters you can stack on the Rollei 35 s before it starts to vignette your image.

I know different filters are different thicknesses, but just as a ballpark, is only one filter all I can use on that little 40mm lens before the filters start to creep into my frame? Or can i get way with stacking two filters?

The filters I intend to use are Zeikos CPL 30.5mm and some no-name 30.5mm 720nm IR filter.
As you can see from the photos, the CPL filter is almost double the thickness of the IR filter.

So I just want to see if anyone has had experience with stacking filters on the Rollei 35 S? I dont want to have to blow a roll of film to find out if it will vignette or not.

Actually there is a way you can kind of see in advance. You need to put the filters on and then, with no film in, take the back off the camera and open the fstop all the way and hold the shutter open in B. Now put your eye right up to the back of the lens and look from one edge of the film gate to the other edge of the front of the lens. If you see can the edge of the filter it will vignette. If not, it should be ok. Back when I used to do commercial photography with a view camera, I would tape the lens shade off right to the edge of the image in order to eliminate any chance of flare. I could look through the cut corners on the ground glass through the lens and see exactly where to put the tape.
Same sort of principle.

Awesome! That is a great idea! I have a roll in now, but I will definitely do that between rolls. Thank you.

Filters have to be chosen with the very film in mind.

Employing the spectral transmission characteristic of polarizers for film capture makes no sense.

A step-up ring that lets you use much larger filters should work.

Thanks guys! So AGX, if I have this correctly, you're saying that I need a particular filter depending on the film that I am using. So what filters what I need for these three films:

Rollei IR 400
Ilford SFX 200
EFKE IR 820 nm film

I bought some specialty film from the film photography project that was hand rolled
(Link here Fr the color film I bought: Dead Link Removed)
(And link here for the b&w film I bought:
Dead Link Removed)

Right now I have an R 25 filter, which many threads are saying will not even work for IR film, but the feeling tired preproject recommended it for their film. I also have an R 72 filter which I'm told is a "true"infrared filter.

If you are saying that stacking a polarizer on top of either of these filters is not going to give me greater contrast in the sky, then please tell me which filters I should use with the films listed above. Thank you very much.

Sorry for the typo, my phone auto corrected the "film photography project" to "feeling tired preproject".

Kind of funny because I'm on set right now and we haven't started shooting yet, and I didn't get enough sleep, so I am literally "feeling tired pre-project" as I type this. Freudian. My phone knows me better than I can imagine.

Anyway, all I want to do is take pictures that I like. Infrared pictures. So any help in filtration choices to properly exposed these films for dark skies and white trees would be appreciated.

If it were me, I'd get the filters I was considering and shoot the same scene under the same conditions with each of the filters in turn, taking notes along the way of course. Aesthetics are always going to be subjective, and only you know the look you're trying to achieve, so why not use a few rolls to establish your own data set?

 

[Daniel Huiting]

I definitely can/will do that. I'm planning to do a big developer shoot out anyway, where I light machine in a controlled environment and shoot a couple rolls of the exact same photo at the exact same exposure, and then cut off pieces into them in different developers to see how they work for me. So I can do that with the infrared as well, I was just hoping to get a leg up on the situation if anyone has experience with this particular films.

I completely understand what you're talking about with things being subjective, but I'm hoping to get the classic "white trees dark sky" infrared photos that seem to be so boring/passé to some folks. I haven't "seen one white tree, seen them all" yet. I'm just starting so it's still exciting to me.
