I have 6 more rolls of the brick left, so I will do one in Rodinal and then one in Xtol with more exposure, more like ISO 3 instead of the calculated 12 with an R72.Quote:

At least we have these two, I can do a lot with that.
Plus, SFX can be loaded in daylight and does not require special focusing. HIE was fun, but a PITA.
Wait why doesn't it require special focusing?? I thought all IR films needed to be set to the IR mark on the lens? (The red line for the wavelength shift). I just shot my Rollie at that line, hope it comes out in focus...Quote:

If nothing else, it would allow me to be a bit more objective in my assessment of the capabilities of the film.

If your shots were of landscapes, you are probably okay due to depth of field. If you were working at closer distances, you may have problems.
Scroll down to "Secondary Spectrum" and look at the graphs of focus shift wrt wavelength for different kinds of lens design. SFX200 is only sensitive to about 750nm, which is only just off the right (red) end of those graphs, which means there is very little difference in focus between the most-extreme part of the spectrum it can see and what you can see. If you use (say) a red-25 on SFX, then about 80% of the exposure is visible light anyway! Even if the IR image was visibly focus-shifted, it's about 2 stops down.
HIE was sensitive past 900nm, which means it could have significant focus shift even on otherwise well-corrected lenses.
Thanks for the info, it was mostly landscapes, on my Maniya 7 and 43mm lens but still, kind if lane there's a significant travel distance from infinity to "infrared infinity" blah wish I had known... Well I'll find out Friday...Quote:

Stone,
I correct focus using the IR mark on my lenses when using Rollei IR 400. I tend to shoot landscape at medium to small apertures and it works for me, even including close foreground. I hope you get some good images. Alex
