Hi All,

I've uploaded a new article with images I shot with my camera converted
on infrared photography to:

just a thought..

The shooting I've done with Kodak and Konica IR cut through haze like a
knife.  There were shots I made in the canadian Rockies where I could barely
see the next mountain, yet after deving the film I could see to the horizon.

I notice your IR converted camera tends to show the haze rather than cutting
through it - have you done any tests to see what the relative sensitivity of
the snesor is at various wavelengths?

Hi Karl,

No I haven't but it's been on my list of things to do for awhile. It may
not be so obvious from these shots but I have found my converted 350D
does cut through the haze, at least a lot.

Cheers,

Wayne

I've tried various filtration with my Fuji IS-1, from 720nm to 950nm.  
Haze penetration is definitely better with deeper filtration, but quite
good even at 720nm.

http://www.flickr.com/photos/jputnam/518759534/ is one example, a view
of Mt Rainier from 40+ miles away.

What is more sensitive to IR, a converted CMOS camera or a CCD-based
camera?  I had heard that the Nikon D40 was the most IR-sensitive
unmodified (aside from Leica's "mistake" with the M8) DSLR.
