Wondering how this compares to digital IR?
Kodak High Speed Infra-Red (HIR)
Nikkor 24mm f2 (iso 200) 25A Hoya (Red filter) FM2
Developed Rodinal 1:50.

Theses shots remind me of the joy / frustration of shooting IR with film. I love these shots, the've got that incredible "glow" that IR film offers that digital lacks. Still, digital likely offers a higher "keeper" rate when shot with modified digicams that facilitate live composition ie previsualizing the IR photo on the LCD or in the EVF (electronic viewfinder).
What ASA did you expose at ?
 
I shot a roll of infrared film maybe 41 years ago. Needless to say, I don't remember the details, but I don't remember nearly the grain in yours, but I'll check on it tomorrow. I contact printed them to slides as I was big on B&W slides at the time. Recently scanned the slides. I expect that however I did it I wanted to keep the grain small for projection.

I was using a Kodak rangefinder camera (circa mid 1940s) at the time and used a deep red filter.
 
Glow or lack of it in digital, at least to my eyes, is just a matter of how it is post processed.

The biggest difference I see is the much more apparent grain of the film shots.

Yes, there's a definite difference .. more depth perhaps? Actual viewing conditions should be taken into consideration.
I printed some IR's on Ilford Gallery paper 11x14" then Sepia toned them.
Alway's washed for Archival Permanency. Should last many years to come.
The actual prints have a kinda glowing with depth to them.

What ASA/iso ? has been somewhat of a big secret with HIR.

Generally, from 200 upto 400 on a hot summers day.
Develpment times has a say in the matter as well.
Rodinal was a very clean and simple formula for high acutance development.

Could be the grain is due to the high acutance developer Rodinal.
Which maybe defunct btw.
D76 was softer with less actual graininess

Hi Ed, once again grain probably the development and PP.
I must admit that I've yet to actually see a well printed IR shot yet.

OK, here are the two best. Really dreadful!

I did take a bunch of mountain shots, but I was disappointed with the results and apparently didn't save them. (I had thought that infrared had some magic fog cutting capability).
 
I wasn't criticizing your processing ... just pointing out the grain and glow can both be adjusted in post to digital IR.

Thank you very much for taking the trouble to post talmy.
Intersting and nostalgic photo's. Keep them safe.

I remember reading somewhere that IR was developed by the US military, not really sure though of the actual capabilities regarding fog cutting.
Perhaps someone out there knows more about the actual history of IR?
Cheers,
