Thanks Keith

Although personally I think it could be a lot better with some decent 
light. It was about as flat and overcast a day as they come so it can only 
get better ;-).

One problem that I have found though is that I was getting some 
considerable light fall off towards the edge of the images.  I'm shooting 
with an 8mm circular fisheye, one of the benefits of which for this sort of 
work is that there is no light fall off with normal films. With IR film 
however, it appears to be quite pronounced.   The sharpness across the 
image was consistent. If anyone has any ideas??? or am I stuck with it.

Film was Konica IR, stupidly shot handheld as I was testing a new method of 
aligning the camera. (1/8sec @ f4, hence some of the blur) I've added a 
second panorama to the page and you can see on this one how the density 
differences at the edge of the image show up the vertical seams between 
images. I can correct this a bit better than I have done here but it's a 
lot of work I'd rather avoid.

Will see what happens with my next test rolls which will be in better 
conditions.


Cheers

Ben
