Comments:  I expose this film through a number 25 red filter, with an effective exposure index of 12 or 6 (I usually bracket the exposure).  I give 30 seconds initial agitation, followed by 5 seconds agitation (2 inversions) every 30 seconds.  This time is for a diffusion enlarger.

Comments: For those who have hoarded some 4x5 Kodak IR sheet film. ISO 400, #25 red, Zone III deep shadow placement, HC110 @ 6 mins-68*f. deep tank w/hangers.  Pulled out/re-emersed in tank once every 1 minute.  This gives normal contrast range with highlight halation.  ISO 50 w/#25 red or #87b with zone III as deep shadows and 5 minute development time gives really dense grainy results.  Print with a very hard filter for maximum grain in print.

Comments:  Using a red filter and metering through the lens.  I agitate for the first 30 seconds and then for 10 seconds every minute after that. I bang the bottom of the tank on pick up and when I put it down.
