My regular exercise before I put negative in a negative carrier for enlarging.

- Wear gloves.
- Carry the camel hair brush in the pocket.
- Take negatives carefully from sleeves.
- Bursh it gently on both sides.
- Put it in a negative carrier.
- Print.

Occasional problems: Tiny strand(2-3mm in length << 1mm of width) which are invisible to eyes got magnified on the prints. Sometimes right on the face which is very distracting esp., when I try to show the prints to my wife.

May I know how to get rid of those strand?
