Thanks Robert. Any noticeable IR effects on an overcast day and what settings would you use?

Hari,
My experience with EFKE 820 with the Rollei IR filter in full sun is f3.5 at 1/30. I wish it were a faster film,, but it is what it is. The exposure is the same for Aura.

Thank you for the information Carlos. I have a Rollei RIII Infrarot filter (extremely dark red, much darker than R25) that I'll be using with Efke IR820 and Efke IR820 Aura film. I do know that exposure and filter compensation for this is very much trial and error. However, does anyone have data or experience as to where I should begin in terms of bracketing my exposures? Thanks.
