Rollei Retro 80s and filter question

[destroya]

A friend as a gift got me a 100 foot roll of Retro 80s. It came in today. I read a few places that retro 80s, having extra red light sensitivity, only has a one stop filter factor when using a red filter and an unknown factor for an IR filter,. i read this as well as heard it from friends. but they use range finders. so my red filter has a 3 stop factor. I'm using a TTL meter, nikon cameras, and want to know if the filter factor is only 1 stop, do I need to manually add exposure when using a red or IR filter? Anyone who has used this film, I would really appreciate and help or guidance.

thanks as always,

john

If you are using the camera's ttl meter and metering with the filter you want on the lens then no adjustments necessary.

I cant help you if you use another rig that is non ttl as I've not used this film stock yet but I have read it is a very sharp, grain free film for 135.

Indeed...

Also, as for the red filter, you may want to watch out for tonality. Rollei 80s is a very contrasty film, and it's possible that you be more pleased by its tonality without using filters.
Here are two samples, from my experience, no filters: http://www.flickr.com/photos/pedrcruz/8631599969/ and http://www.flickr.com/photos/pedrcruz/10617829536/
All in all, I should add that Rollei 80s is the best film I ever used.

The compensation needed for a TTL meter metering through a red, dark red or even near IR filter depends on the combination of spectral sensitivity of the film, the characteristic of the filter and the spectral sensitivity of the meter.
The proper way to find out your compensation is to bracket a scene, pick the correct exposed frame and in future use that compensation.
With a dark red filter (Kodak 29) I had compensations from +3 to -1 depending on camera and film.
In my Canons with a 29 filter a near IR sensitive film like R80S needs -1, Fuji Acros needs +1 or even +2.

I shoot it at ei 200 outdoors and develop with Rodinal 1:100 for one hour stand. Great. No filter.

I have used this film and found it really prone to fogging. I'm not sure what caused it, but I would recomend loading and unloading the camera in darkness. I use Nikon cameras with TTL meters and I'm sure that either the camera manuals, or the info supplied with the Nikon filters suggests adding an extra stop to a TTL reading with the dark red filter(Nikon R60) in place. I would also agree that the film can be quite contrasty. Alex

> unknown factor for an IR filter

A 720 nm filter can be used. You may start with giving 4 more stops exposurer in comparision to unfiltered.

RR80s tend to block the highlight, especially with Rodinal. This effect can be eliminated totally by using Atomal 49 1+1.
