Yet another Kodak Ektar 100 question

[Uncle Bill]

I picked up two rolls this morning to try out in the near future, I would like to know what I should rate this film EI wise to get the best out of it. Should I aim down towards 80 or 64 ISO?

I used it at 80 iso, and it was ok.

 

[Tim Gray]

I used it at 50 and it was ok.

Bill, I agree with 50. Here it is at 50 w/ Nikkormat 50/1.4
(there was a url link here which no longer exists)

I'd rate it and all other c41 films at half box speed until proven different by the results (I've only shot one film that was best at box Ultra 50)

box speed

Here it is at box speed, developed it myself in a C41 home kit.

It looks very well suited to perking up dull colors.

It worked at ASA 100 when I printed it in my darkroom.

 

[Alexander Ghaffari]

Shooting it at EI 64 gave me good results.

 

[Tim Gray]

It sounds like you should shoot it anywhere from 50-100

 

[Uncle Bill]

So it's settled when I try out the first roll at 64 ISO and I pretend I am shooting Kodachrome.
