Are there any programs that can convert color infra-red photos to actual color?

Well, you've convinced me. I still think B & W infra-red is a
good idea for not bothering a band or crew though... or am I wrong
about that too? Oh God don't let me be wrong about that too... can an
IR flash be seen (I'm hoping not)?

BW infra red changes the tonal quality of BW: You may also have focusing
issues, unless you have an infra red marker on your lens. I have
starting experimenting with it, by having one of my digital cameras
converted to IR. The only way you can get IR color is in post
processing. You can convert some colors to pseudo IR color. For rock
bends you might get some interesting effects, but don't count on
faithful reproduction.

Here are some links to get you started:

IR is good for snipers and for special effects, but if you're shooting a
concert there is no substitute for high ISO and large aperture.

Some fabrics are somewhat transparent in infrared--you may end up
effectively shooting your performers in their underwear.

Gee... that would be... terrible... Yeah, I better stay well
away from that...

Here's one
example that demonstrates the issue:
http://www.youtube.com/watch?v=BzHCDknFbDU&feature=related. If you
search youtube on "see through clothing infrared" or "nightshot see
through clothes" you'll find numerous other examples.

I remember hearing all the hooplah about how the Nightshot was
"seeing through clothes". Apparently it left little to the imagination
before they changed how much it sees. Damned corporate worrywarts...

Why would you want to do this, even if it were at all possible?

* * * * I was recently covering a concert for a local magazine, and
asked a stage manager about taking pix with the flash. He said go
ahead and take a few with flash, but not too many, so as not to be
distracting.
...
* * * * I suppose for a huge event I could take one with flash and
then recolor manually and submit the pix a couple years later , but
that's not really what I was looking to be able to do.

It is often not necessary, or even desirable, to take pictures with
flash at a concert. These were taken (not by me) without flash. I
wouldn't say they are great, but it shows that it is at least
possible:

Those were taken with a Rebel Xsi, which I think is similar to your
D3000, as far as sensor size.

You could also get a fast prime lens, or perhaps even a camera with a
FF sensor if you wanted better low-light performance.


Thanks for the advice. I think there are some settings I could
have played with on mine that would have allowed me to get a better
image, but I've got to read up a bit on it yet.

If you are still considering IR, you could buy a use D70 or other
camera and have these guys do a conversion for you. That way you would
have a dedicated IR camera.
They have several different options. Also check their IR gallery.

Thanks much.

I'm not in a position to buy another camera just yet, but I
might consider this when I am.

Yeah, look at the "ISO Sensitivity" section in your manual. I think
you can get that camera up to 3200, but you need to see what that does
to noise.

It gets pretty noisy at the higher ISO settings, depending on
how much available light there is. It's okay though, because I can
always shoot with a faster shutter speed in RAW format and then
brighten it up without banding at home later on.

I know that color infra-red images look really weird (for lack
of a better term), but I once read that infra-red light cuts through
fog/haze etc better than regular light, which I suppose is why B & W
infra-red shots always look better than B & W shots without IR flash.
So I'm wondering if there's a program that could accurately
predict based on IR color what the colors present should be, and
convert them, so it would be possible to do color shots better in
haze, etc.
Anyone know of anything like this?

I was recently covering a concert for a local magazine, and

I had read about B & W infra-red photography in an old issue
of Popular Mechanics, I think, that my Dad had lying around somewhere.
Then I had read an article on color infra-red, and I thought "Oh, well
then I'll just shoot pix like that in color infra-red and convert them
on the computer back at home. People can't see infra-red, so there
won't be a visible flash, and I'll convert the pix and have great
shots that didn't bother anyone".

I'm not sure that is practical, while you can't see infra red I'm not sure
if ther';s a flash that flashes infra red.
I've used colour IR in the past in was the old E4 process
(slide/transparency film) and from memory the film is very slow for gig
purposed under 100ASA.

It's since been explained to me that there's no method of
converting the color infra-red pix, since the information about actual
color is just as gone in those as it would be in black and white.
I suppose for a huge event I could take one with flash and
then recolor manually and submit the pix a couple years later , but
that's not really what I was looking to be able to do.

I've used IR a few times, and gigs quite often. I;m not sure if it'll be any
good for gigs though.

What I'll probably end up doing is just shooting with a high
enough ISO and fast enough shutter speed to have an image but not have
it blurry, and if I shoot in RAW format, brighten it up later. I've
noticed that the RAW files don't have "banding" after changing the
colour or brightening, since there's so much more information there.
