Sweet, thanks! Is the IR filter a R72? Interesting that there is quite a bit of wood effect already with the red filter. I prefer your results @25 in the first two scenes unless the highlights are exaggerated in this contact sheet, that's hand-holdable in the sun, nice!
I looked at these again and certainly the sky is blacker at 25 in each case and still has quite a bit of wood effect as you say. It does also increase the scope for hand-holdable shots. So on balance 25 might now win it for me as well
Thanks, Sterioma. The individual scan now convinces me that for what I like in IR, the speed of 25 is the better of the two. All I need to be sure of is that I can do a print under an enlarger that can match the look of the scan
