Another nice video, Andrew but at the risk of appearing thick or lazy or both, I for one would have appreciated another slow and deliberate running commentary of how you arrived at your exposure and aperture setting for Rollei IR

The bird by the way was guffawing and saying to his youngster: "Now just look at the trouble forgetting to take an iphone for a photo causes"

Thanks! I'll consider leaving that stuff in in future. I usually cut it out, as I think it's too much for people to bear...
The crow startled me! I thought my little friend had followed me all the way from Riverview Grounds!

My exposure process is:
Use box speed, so Rollei IR 400 is at ISO 400​
I take the darkest shadow that I want its detail and get the f/stop and shutter speed.​
Set that in Zone 2, Zone 3 or Zone 4 and open up 3 stops, 2 stops or 1 stop [OR change the shutter speed by 8 times, 4 times or 2 times]​
Then for the IR filter R25 3 stops, R29 4 stops or R72 [720] 5 stops​
Since I start from box speed I have not needed to correct for reciprocity yet.​
I have not had an exposure problem yet. What is your exposure success rate?
What is the OP's method? What method do others use?

I usually use the film at EI of 1.5 (to accommodate the 720 Zomei IR filter)... I almost always place important shadow areas on zone III, and give 2 stops less exposure for that. Then I add three stops to get me to EI 1.5, as my metre only goes down to 12. Then, I add reciprocity compensation if necessary, and it almost always is. For some of my shots during this trip, I shot at EI .75. It's too much exposure, and negatives were too flat. EI 1.5-3 is ideal with this filter.
I either develop in Pyrocat-HD or Xtol-R. I'm going to do a side by side with the two developers eventually.

So your EI is 50 or 100? If so, that is a lot of down rating the ISO. Why? The Zone System will take care of the shadow detail without the downrating.

No. My EI unfiltered is 200. I work this way to keep shadows open.

Thank you so much, darr! The third video will be posted next Sunday, and the last one from the series on the following Sunday.

If I meter a shadow/dark area and I want to put it on zone 2, I'm going to take my meter reading (which corresponds to zone 5, in theory) and close the aperture by 3 stops. Opening up by 3 stops, as you state, from the meter reading is going to put that dark area on zone 8, not zone 2. Then I would account for a filter, if one is being used (almost never).

Not speaking for anybody else....... but it was probably a "slip of the tongue"
He most likely meant just as you say

Since you already open one stop for shadow detail why bother with then doing the Zone Systema/ OR just use the box speed use the Zone System and then adjust for the filter. Derating the film by one stop is an unneeded extra step. Do you agree or is there something that I am not seeing?

No, it's not an "unneeded extra stop". Maybe for you it is. But I'm not shooting or processing film for you. An EI of 1.5 to 3 works very well for me.
