Hi, I removed my hot filter from my D70. Does this make my camera full spectrum now? I have tried custom white balance off of bright green foliage, but cannot get the leaves and grass to come out looking white. This is without using a ir cut filter, just a uv filter.

What did you replace the hot mirror with? If it's glass or a UV filter then your conversion is properly known as two spectrum as it won't see UV significantly. For most IR type shooting this is fine, allowing filters to be used to give a very wide range of effects.

I never get white foliage from my full spectrum camera without desaturating unless using an IR only filter in front of the lens (720nm or preferably longer). With no filter added to the lens there will always be enough green recorded to give the foliage a definite hue.

With a red filter I typically see blue foliage SOOC (which most IR Photographers change to yellow with a red-blue channel swap). I prefer simply playing with the hue slider

Blue filters often give yellow foliage SOOC...

Actual effects on these filters will of course be highly dependent on the CWB.
