reading a densitometric test


Recommended Posts

haven't dealt  with these numbers in several years now, and really forgot how to read them. 

I only know it seems way off, but could someone remind me how to read this stuff? 
this is what I got from the lab reading of our gray card: 

0.27 0.60 0.99 is the reading in the perf area.
 
Thnaks all.

I suppose they gave you the D-Min values (perf area?) to show if and how much the filmfog has increased due to old age, radiation etc.

First to know is which filmstock and compared the values to a known fresh stock reading.

Those are the log densities in red, green and blue. As Dirk says, we don't know the stock, but here's a curve for Vision 500t (page 2)

Your D-mins are a little higher than that so presumably you have some extra fogging.
