None of the three look particularly IR-like to me. But the CS6 fake,
while
clearly the worst rendition of the subject, strikes me as the most
IR-like.

But I'm not sure what I'm looking at. Was any of the three taken with
an IR
filter? Had the camera undergone IR conversion?

Bob.

Only the fake IR (bottom right) was meant to resemble an IR, and faux-IR
isn't a replacement for the real thing. It is just the Adobe allegation
that it can be done to to some images to fake it. So for me this was
just an exercise. Not a particularly successful exercise, but an exercise.

There was only one capture and that was a plain old vanilla color shot
without any filter. The B&W conversion was just that a B&W conversion,
and not intended to be anything else.
I still feel that if I am going to explore IR photography, paying the
$275 to convert my D70 is going to give me the best results.



But becauseof the focus issue, you might want to give them the lens you
will mostlikely be using. With my P&S it was not an issue.

For the D70, LifePixel uses the standard calibration with the 18-70mm
DX lens, and they don't require it to be sent to them with the body.

I meant to say tell them which lens you will be using.

It depends on the sun and the clouds. Note how the trees change from
black to white as the clouds move in this 10 second quicktime infrared
time-lapse movie (the change occurs at the 5-second point):

Also, it is difficult to get decent infrared photos when you need 30
second exposures. You can get hand-held IR shots with a camera without
an IR filter. Try holding the filter in front of your cell-phone camera.
