Cleanup, rearranging last section to make it clear it refers to filter use vis a vis rect. hoods.

Photographers need their ND grad filters & polarizers to work in any camera orientation, so they tend not to be used in the context of a matte box with a built-in aspect ratio. My point there was that rectangular matte boxes like used in video don't work as well in photography. But you are right, and after rereading, I can see that my point wasn't very clear. | |

Some lens hoods — particularly the generic ones that attach to the filter threads — do allow that, but lens hoods purpose-made for a specific lens generally click into the proper orientation. Thus, as the lens rotates around its axis, so does the hood. | |
