87c, Red 25, and more...

["Jon Witsell" <wfc27@xxxxxxxxxxx>]

Hi all,

I’m taking a road trip to Portland, OR. this weekend and I want (weather 
permitting) to shoot a full roll of HIE with my 87c. I have been swapping 
back and forth with a Red 25 and have had random results with the 87c and 
want to nail down a consistent method for using it.

How does this sound:

Set the film speed to 12 ASA.
Meter the scene.
Set the shutter speed to 125.
Crank up the film speed until the meter reads F/11.
Bracket +/- 1 ASA stop.

I tend to like somewhat underexposed shots with heavy blacks, so I may 
bracket two ASA speeds higher.

Does this sound about right?

Another question: On page 101 of Laurie White’s book, the “Exposure 
Adjustments” chart says when using an 87c you should increase exposure by 
12+ (!) stops. Is that correct? I thought it was more like 5. What am I 
missing?

Yet another: I had a interesting experience with a roll of HIE last weekend. 
Usually I set my ASA to 200, meter through a Red 25, and bracket +/- one 
f-stop. This usually gives me predictable results. This last Sunday, 
however, was very bright. It was one o’clock p.m., cold, clear, no wind or 
dust, and the sun (here in Seattle) was low in the southern sky.

Every shot with the Red 25 was blown out! It didn’t dawn on me (no pun 
intended) until I came out of the darkroom with half a roll of smoked HIE 
that there must have been an immense amount of IR light that day and my 
meter was giving me inaccurate readings--if I had used the sunny sixteen 
rule, I would have set the shutter speed several clicks faster.

Anyone else have this experience?

A friend once said to me “Character is what you get when you don’t get what 
you want.”

Jon
