DMSO/Re: Canon D-30 / Nikon D1 - suitable for digital IR?

[Cor Breukel <cor@xxxxxxx>]

I work in a lab, and we use DMSO routinely: a word of warning: DMSO is
toxic, and has the nasty habit of passing to your skin easily, so than
you have a strange taste in your mouth. So be carefully, use a fume
hood, or better avoid all together.

Best,

Cor
