I've acquired a Colorstar 3000 analyser with b/w sensor (the 301).
It has the 54mm diffuser cap, not the 10mm spotmetering cap.
The producer is out of business.
My question to anyone using the Colorstar (or similar) for B/W work
Would it be much of a problem using it without a cap at all for spot-metering ?
Common sense hints two possible problems:
-without a cap light from the side could influence the metering
- the naked cell is vulnerable (dust,etc;..)
What do expert users of this device have to say ?
