Here is one I took the same day at about 10 am, clear skies. I like to have the sun at my back whenever possible to illuminate the subject better, and to reduce flare. ISO 100, 18mm, f7.1, 21 sec, RAW Creative Style B/W, contrast increased 50 in IDC and .75 exposure increase, converted to Jpeg and resized. It was November 22nd, so not may leaves left, but you can see on the other trees that still had foliage how white they are. John
Edit Cokin SFX gel filter- should be 720nm....

Thanks, Doc. I was so happy when I found out that my a200's sensor was IR sensitive. I've been itching for Spring ever since.
Birma I came across this:

I hope it helps.

Dead wood, brown grass all have low IR reflectance. Wait until spring and you will notice a huge difference.
EDIT Sorry Birma- I didn't see the sentence at the bottom.....You are getting close.
As far as the technique I used in my tree shot, I shot RAW ISO 100 or 200 I'd have to look. Creative style B/W. I then played with the contrast, exposure, DRO in IDC to achieve the 'glow'. I am usually at about f7- f11, to negate focus difference, and I just count out the seconds with my manual release cable. (sorry I don't do it more precisely!) I'll post some others with the exposure data. I'm biding my time right now by scoping out locations for spring... Hope this helps- John
That is a great help - thanks John :D . I'm pleased to know I'm on the right lines. I suspected that more "green" was needed. Roll on spring!.
