    One film, two iso ratings.

    I just found out that the Tri-X 400 film that I had pulled from one camera and finished in another had been misscalibrated. The first rating was iso 400 in a Yashica T4 while frames 15-30 were shot in a Nikon FE and rated at iso 200.
    How does this sound: Rodinal 1+24 for 15mins at 20c.

    Thanks,
    Mike

    That sounds way too much.

    I do the film 1+50 for 13 minutes when shooting @ 400. For 1+24 (or 1+25) I would go for 7 min @ 400 or 4½ min @ 200. Try giving it 5½ and it will be almost in between. Then you will get slighty overdeveloped negs for the shots done @ 200 and slighty underdeveloped negs for the shots @ 400. Both will be printable without much loss.

    Or try it for 10 min. in 1+50.

    That's only one stop difference. I would develop the whole thing to 400 - it's easier to control high density than thin negs with no shadow detail.

    Sounds reasonable. I can join this opinion, too.
