dust and glass
A tip for identifying dust on glass negative carriers:
When using glass neg carriers, I put enlarger lamp on and open up aperture. With nothing on baseboard on no neg in carrier, I slide neg carrier in and out of enlarger looking at baseboard. If there are any specs of dust on glass, you can see them moving on baseboard as you slide the neg carrier in and out.

focussing will help but of course it depends which surface the dust is on.

Anyone ever see those little dust mites moving on the glass negative carriers. What are those guys living on?

And, before someone tells us that "most of the dust in your house is dead skin cells", it ain't. Urban myth. Dust is mainly just that: dust. Mostly fine soil and vegetation and brick and concrete, plaster and wood dust depending on where you live. Only a tiny amount is of human origin (something like 2% IIRC). It was a question on QI some time ago. Alan Davies collected the inevitable -20 points... |
