Barry,
That must be it! It must have scratched when I cleaned it (microfibre cloth!) or something else. I always get the most horrendous flare right down the middle 20% of the image!
But now I'm really reluctant to buy a replacement. I'm inclined to just forget IR for a while...

Angelo, thanks for your comment. The only issue I've found with the Cokin filter is that it scratches really easily and once marked it picks up flare from the sun if the sun's anywhere in a 180 degree arc in front of the camera - annoying!

Stefan, fortunately the filter seems to add a consistent 3.5 to 4 stops to the exposure. Given the latitude of B&W film for burning and dogding, being out by half a stop isn't too much of a problem. The IR effects only become really obvious in bright sunlight so it's a nice film to use on sunny days when colour would look a bit bland. Exposing this image was pretty straightforward. I always use a handheld spotmeter and I took readings from the darkest area, the brightest area and the mid-tones in the central water and fells. I had to estimate how much the sky would be darkened by the IR filter and guessed that it would be about 2 stops and this turned out to be about right. So I used the exposure from the mid-tones as there was plenty of exposure latitude to enable me to capture detail in the shadows up to the whiteness in the clouds.

Wonderful tones, Barry. Not much of an infrared effect, but then the I have heard that the SFX is really subtle. It works well here, despite a lot of grain showing...
Lovely clouds, and the dark areas bottom and top balance out nicely. A nice mist and some beautiful details in the foreground and distance round the image off very well.
I am glad the Cokin IR filter is working for you. I've had nothing but grief with my one.

Great reflections and dramatic tones. Good work.

The straight ISO rating for SFX is when you don't have any filters though, don't you have start guessing what you have once the IR filter is in place? Clearly it is working pretty well, and seems to provide a middle ground between pure IR with its sometimes alien look and this which just adds "a little extra".

Stefan, you're right about the mist, the IR element of SFX gives it an unearthly feel. I haven't used pure IR film before, only SFX which has an extended latitude that extends down into the infra-red but with the benefit of an anti-halation layer and a true ISO rating. It can also be changed in daylight conditions which is handy!

The white band (fog I presume) looks appropriately unearthly. Is it difficult to meter for this combination? Have you worked with straight-up IR film instead (since you are using an IR filter)?
