Ive been seeing quite a bit of infrared photos on dp challenge lately. Now I wasnt aware that it was possible to take infrared pictures with a digital camera. Does any one know how this is possible? Thanks.

you can use IR filters and editing in image editors to get a digital IR photo.
some digital cameras ae better at this than others, due to some have IR blocker filters built in.

| The Fuji 602 captures IR, but you have to use the R72 filter, and a really long exposure time. |

| I take infrared on my S2 all the time using an R72 filter. Just for fun take a picture of the front of a remote control while pressing a button. You should be able to capture the infrared light from the remote. |

| ....forgot about that. That's a great test to see if your Cam will at least detect IR.. |

New to this site, so apologies in advance if answer is not what is required.
I have learnt a way to take IR pictures with my D70.
Switch in to any of P S A or M modes. Then you need to go to Preset White balance. Put an IR filter over the front of the lens and then follow the manual instructions for measuring a value of white balance (page 52 of the D70 manual) This means putting a white card or object in front of the lens, go to "Measure" in the "Preset" menu. Press the WB button until the PRE icon starts to flash. Frame and press shutter release all the way down (No photo will be taken) If the camera has measured a value, it will flash "Good" in the screen. If it hasn't it will flash "No gd". Repeat from Framing the picture. I then also dial in +1.3 exposure compensation to whatever the meter reading is. The results have been different - the pictures came out with a blue tone, but it was pleasant, and if required, can be removed in your photo editing software. |

Usually you want to set the WB before putting on the filter, but if it works for you and you get the results you want, then go for it!
I am still experimenting with IR on the D70 (was using a Nikon 5700 prior). Only have a filter to use on my 50mm f1.8 at this time, so I am limitied in range, but it is good to experiment to figure it out.
I will have to try out the Exp Comp, see what happens.
There is a great PS action here that does some correction that looks pretty good at the moment.
I have noticed so far that the D70 gives more of a red hue, right from the camera (compared to 5700), so I have some adjusting to do.
Love to keep this thread up and going with any and all tips.

I figured out that setting a custom white balance was essential with my 602, but what about shooting raw? I assume you can ignore wb when shooting and play with the setting during conversion to get the best effect. Anybody tried this?

Here's a thread, without examples, of the Fuji s7000 (and s5000 and s602 as well) and their ability to use IR filters:

Nothing really that happens with RAW, besides being able to adjust everything (duh), like a normal RAW (mainly the saturation, shadows, etc.). Alot of that can be done just IN PS, also. I found that the temp is coming out consistently from the camera at 2000 (using the WB WITH the filter on). Moving it to the right at all, does brighten it up, but blows alot of highlights. Desating it in RAW does not seem to help (I like to use DigiDan's action for that).
More experiments to do, since it is such a bright and few clouds in the sky kind of day here in CO. |

I use that technique also. With 1 small variation. I use any well lit (sun light)subject to set my white balance. Not a white/grey card. This will give you a tint to your images, which can then be removed or modified. I have also found that different IR filters leave different colors. My Hoya 72 is much different from my B+W 93.
Here's another good IR thread
