How were those graphs created? How would I go about making some on my own?
You'll need a densitometer and you will also need to devise a procedure to test your film with the different filters.
Without going into so much trouble, you can also test visually, by simply photographing a colour reference chart using the different filters.
"To a man who knows nothing, mountains are mountains, waters are waters, and trees are trees. But when he has studied and knows a little, mountains are no longer mountains, waters are no longer waters, and trees are no longer trees. But when he has thoroughly understood, mountains are once again mountains, waters are waters, and trees are trees."
