Best b&w filter for grass, brick

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.

Blue filter? Would definitely darken grass without affecting the red brick.

A blue filter, like a Wratten 47B, will pass only blue light, approximating the look of blue-sensitive emulsions of the past. Red, being on the opposite end of the visible spectrum to blue, would be darkened. A true, saturated red would be rendered unexposed on the negative and black in the print. So, that blue filter is going to darken red bricks.

Best,

Doremus

Tell me more! I have a densitometer, an x-rite 810 and I have time. I’d love to take on that project.
