...so I sent my trusty (but now third down the line) D70s to the guys in
Washington to get set up for Infrared. I actually plan on using it for
a "second" while I shoot what amounts to be sports...kids on a football
field or in a gym. Just looking for some solid info...should be fun!

why would you need infrared for sports, especially outdoors?

...just a thought...I like the 'negative' look,


infrared won't give you a 'negative look.'

if I can get something
going that doesn't require gobs of 'puter time in post, people might
like the option...


use a preset and/or batch your adjustments. if all you want is a
negative look, just invert it and you'll *have* a negative look.

but, really, I'm just looking for sources. Got any?


sources of what? you already said you sent the camera to be modified.

get an infrared filter and go experiment. good luck composing a shot
when visible light is blocked. infrared on an slr that lacks live view
is a pain.

if you don't use an infrared filter on a modified camera (or ones with
weak ir cut), you'll get infrared contamination which will affect the
colours, depending on how much infrared is being reflected.


IIRC there are IR filters that let a bit of visible red through. Might
be a workable compromise.


With digital you don't need an infrared filter. All you do is remove the
infrared filter from the sensor. It's really a simple procedure. I
converted my CoolPix but didn't feel comfortable doing it myself. So I
went to a local repair guy, who charged me $70.
