I shoot color infrared with a Lifepixel converted camera with their enhanced color filter (665). I take a custom white balance on sunlit green grass, and when I open the RAW files in ACR, I get an "as shot" WB of 2000. That seems to be the lowest ACR allows, as I am not able to manually set a lower number. I have tried higher numbers, but they seem to diminish the IR effect I like. I wonder what a lower number would do - is there any way to get a lower WB?

What you need to do with your camera is to go outside, look for a green patch lawn ect and then set your camera as follows:
Go to
Menu
WB
WB Preset
Measure
Override preset data
Yes
Here, follow the instruction on your camera screen.
But Before you take that first picture for measuring, be sure to mount an IR filter color of your choice onto your lens.
Now go out and find that green lawn, leaves, zoom and fill your screen with that green.
Don't worry about the focus.
Take a shot.
If your camera says ACQUIRED you are set to go.
Keep that IR filter on and go shoot.
Have fun
Very simple
I have my Nikon D40 converted to full spectrum as well and love it

I know how to set a custom WB, and I do that (and I noted I have an internal filter). I just can't get a WB below 2000 in Adobe Camera Raw.

ACR cannot do this. You will need to use the software that came with your camera or On1.

Go to the tutorials on the LifePixel site. They walk you thru from setting the WB to channel switching the red and blue Chanel’s. ACR does not have the ability and you need to download another small program (sorry - cannot remember the name. )

R <-> B channel swapping is in addition to White Balance.

Sorry, my mistake for not reading your whole message. I'm bad.

Did you speak to Lifepixel about your problem?
They have a tutorial on their site and it’s on YouTube
Convert a raw Ir file to dng
Using the dng editor adjust the white balance.
You can find tutorials on you tube and kolarivision.com

One question please. how do you set the WB if the IR filter is built in, and the camera is a DSLR with different sensor for focusing/metering? Thank you!

You do a custom white balance on grass or white card or gray card depending on the it conversion. Some cameras can’t do a CWB.
Go to adobe and download DNG file editor. You can create a camera profile that you can use in ACR to set WB properly. There are a few videos online to walk you through the process. Search YouTube for Jason Odell and IR photography. That video will walk you through all the steps. You can also create an LUT to be included in that camera profile to handle red/blue channel swap but that is another discussion.

I believe that it needs to set the IR WB through the IR filter that on top of the camera lens. If the filter was built in on the sensor, for example the camera is a DSLR, so what ever you use white/gray card or green glass, the WB setting will not be for IR but normal picture only! I am confusing!
You still have neutral colors or shades in IR photography so you can set WB in camera. It may take repeated steps changing EV but you can do it.

If you are working with a converted DSLR, the filter is built-into the camera. No added filter is necessary attached to the lens. Or why have the camera converted in the first place? YES, you seem confused. For IR pic's, (and that is why you had the camera converted) Point the camera at green GRASS / foliage, to do a WB setting.

A converted DSLR with an internal IR filter takes the photo and measures the custom WB through that filter. You are just not viewing the filter through the viewfinder.
