Negative Density

[AlanO]

Is neg density the same for all properly exposed film?

Ex - Same scene properly exposed and developed on 2 different films, will enlarger print times and aperature setting be close to identical for same result?

Similar but may not be the same.
Different films have different density characteristics.

Check out these two films of similar type ... Characteristic Curve:

If the emulsion is thicker, you will get different densities for the same exposure. I would hope that most modern manufacturers have similar thicknesses (or equivalents for different compositions), but I know of no confirmation of that.

Thanks for the replies.

Same developer? T here are a lot of variables that can create a different density, including agitation.

They can be similar but printing times may vary, it also depends on enlarger, etc. as well as how particular are you.

T-grain films will look much thinner compared to cubical grain films. At least by 1 stop.
