Fog

When the weather is either very humid or quite

cold, I find working under the dark cloth to be

very difficult. Since I can't break the habit of

breathing (I've done it all my life), the

groundglass, my focussing loupe, my eyeglasses,

and everything else in sight fogs up. Every few

seconds, I've got to stop and wipe off the fog.

It even affects my equipment choices-- I use a

relatively inexpensive loupe because I

don't want to ruin a good one by wiping it with

my shirt, handkerchief, or whatever is handy.

How do other people deal with the fog problem?

Rain-X makes a product that is supposed to stop glass from fogging up. I forget what its called. I don't know how it would effect the coating on your loupe.
