I spent several hours this evening researching 'comparative grain in various films' this evening. It seemed there was little, and all were some "expert" photographer proving to his own satisfaction, why he had already chosen a 'superior' film. Now subjective analysis is important, when it is subjective. But too many had no clue how to compare, or worse were comparing apples to oranges. All without any method or objectivity.

Then I cam across a real gem in the mud! This is a very 'scholarly' look at the whole very complex and intertwined issue, we commonly clump together (pun intended) as "grain".

As a bonus there is terrific information on film scanning included at the end of this. Again, fairly scientific, and objective. Be aware, this never does evaluate film X against Film Y. But you will have what you need to research it out, and decide what factors are important to you, and what is not!

So, if this subject interests you, brew up a pot of coffee, get out your reading glasses, and a dictionary... It's 22 pages (PDF) of the best info you are going to find on the subject anywhere.
