Q: 9. Hi there! I was wondering if this type of filter could be used to decrease a bayer sensor's sensitivity to green light--while still balancing the camera to a proper white balance--resulting in a more filmic appearance in image quality. would this work, and what would you recommend? Thanks so much for any thoughts you might have!!

A: The Tiffen Series 9 1 Cranberry Solid Color Filter would certainly decrease the overall appearance of green in an image, but it would also effect the rest of the color spectrum also, creating a slight (or not-so-slight) cranberry color cast, depending on the scene.

Q: 10. Does this come with a case?

A: Yes, Tiffen 49mm 85B Color Conversion Filter comes on an acrylic case.
