now i am considering color negatives and is trying do the similar
things on them. i always send color negatives out to a lab for
developing, and again, i dont have a densitormeter. can i test speeds
( up to the same lab i used ) of color negatives at home?
I don't see why you couldn't use the same method. A little experiment
might be needed though.

for B&W negatives, i find the 0.1 density above base + fog for Zone 1
exposure. for color negatives, i don't know what density i should
find Zone 1 exposure because there are more than one dyes on the film.
