    I see. That indeed complicates things a bit. Changing bags (or just a backpack that one could use to creat a shaded area) might become more popular with this film. Due to its price, I'm guessing that it will have a limited consumer base anyway, so this should be a minor inconviniece to whoever uses it.

    I may be wrong but I thought these two films had reduced red sensitivity and that's why they are described as orthopanchromatic?

    When I used to use B&W film in 120 frequently, usually 400ASA, I often had no choice but to change rolls in direct sunlight, and personally never had a roll fogged though I can see the sense of doing it in the shade if that's available.

    Ok I'm on the edge on my technical knowledge here but my understanding of orthopanchromatic is that it's less sensitive to red like the Efke 25 & 50 films. I've not heard of anyone having problems changing those out of direct sunlight but might be wrong.

    Using a film through a range of speeds I don't think will be a problem as I've been rating HP5+ from 200 to 1600 without any problems.

    As mentioned earlier I think we will have to wait and test a couple of rolls to see how it works and if it comes up to scratch as an alternative.

    In that case, replace Efke with Ilford SFX and re-ask the question...

    Of course, since the issue is probably the base material, it doesn't matter
