Equipment used:
Hasselblad 500 CM
Planar 80 CF T* 2.8
150 CF T* 4.0
Hoya Filter IR720

Scans:
Epson 3200 with Silverfast software
Adobe Photoshop CS2

Roll 1 Development:
The first roll was developed at 14.5 minutes
Developer Pyrocat HD 1:1:100, 20°C
Agitation first minute continuously
After that 1 inversion each minute.

The first roll was shot at 400 asa. I took 4 stops for the filter, so shot the film at 25 asa with filter and 400 without. The shots where taken in the wood at 2 o'clock in the afternoon. There was a little sun behind light clouds. Temperature around 23°C.

Result Roll 1
After development I saw that the shots with the filter where to light. Some shots I bracketed also at 12 asa and this was the best compared to the shot at 25. So this filter uses up 5 stops and not 4 as I pretended.

PhotoDescription
Roll 1, #1Shot without filter. Tone is good. No grain visible.
Roll 1, #2Is the same shot as Roll 1, #1 but now with IR720 filter.The wood effect is good visible. The tree was actual in the shadow, no direct sunlight.
Roll 1, #3Same circumstance as Roll 1, #1
Roll 1, #4Higher contrast. The sun was shining (no clouds).

Roll 2 Development:
The 2nd roll was developed at 14 minutes
Developer Pyrocat HD 1:1:100, 20°C
Agitation first minute continuously
After that 1 inversion each minute.

The roll was shot at 400 asa. I took 5 stops for the filter, so shot the film at 12 asa with filter and 400 without. The shots where taken at 8-10 o'clock in the morning. There was sun. Temperature around 20°C.

Result Roll 2
The overall structure of the negatives look fine. Not to dark and not to light.

PhotoDescription
Roll 2, #1Inside our house at 7 o'clock.
Roll 2, #2High contrast scene where fog was moving at the back of the house.
Roll 2, #3High contrast scene. About 7 stops. I think I get more out in the darkroom.
Roll 2, #4No direct sunlight onto the grass. No visible wood effect. The grass had not yet been lightened by the sun at all.
Roll 2, #5At 9.30 the light became to hard. The highlights get burned out...
Roll 2, #6Shot at 12 o'clock in our garden pond. The light was hard (direct sunlight). The lilly is almost not visible. The leaves have the same colour.
Roll 2, #7Normal shot taken with a b&w closeup filter. The leave was taken from a plant in the garden just before the shot was taken. The leave was in the sun shot around 11 o'clock.
Conclusion

I like the structure of the film. It does not look like a 400 asa film to me. The highlights in the negative are soft, so probably when making prints in the darkroom the quality will be even better than scanning.
