IR portraits

I wonder what techniques you might be using for B&W IR portrature?

I notice that the eyes, in particular can look very strange. After one pic of my granddaughter, my daughter said she looked like a werewolf.

I like the skin tones, their softness in particular.

Any suggestions?

(I am using a Canon 400D with 720 nm conversion.)

Hi,
720nm is to dark for IR portrait.
Usually I use 590nm or lower for nice skin tones.
eventhough, there is a technique with PS to touch-up all the things.
In my web there are some expert on this IR. You can post your question there.

Peace!
