Rollei IR 400 in mixed light with IR flash
I'm shooting an extended project that will include some concert photography. The venue forbids flash photography during the show, which presents something of a problem. Light levels will be low and I don't want to have to switch to digital for this section of the project.
So, I thought about shooting Rollei IR 400 with an IR flash. I am not looking for the IR look, so I will not use an IR filter on the camera lens.
Instead I am aiming for the IR filtered flash to act as an invisible IR fill light that will be picked up by the extra IR sensitivity of the film.
So, essentially I will shoot:
- Mixed light
- No IR filter on lens
- Heavy duty IR emitting flash (on camera)
- Rate Rollei IR 400 @ 400
Also does anyone have any experience pushing Rollei IR 400 to 800 or 1250?
I'm going to run a few tests in advance, but would like to hear from anyone who has experience with this.
Thanks in advance.
