I was just about to order some Efke 820 infra-red when I noticed it was also available in a version with no anti-halation layer (820 Aura) which was supposed to give a more 'Kodak HIE' look. Has anyone tried it in the 'Aura' version? I should really order some, get off my bottom and try it, but given the current drab weather and non-infra red shooting conditions in the North of England, it may be a while...
Thanks to your post, I just checked Freestyle's Website, and found it (albeit in 35mm only - too bad).
