Any Hints for Making Vignetter

I have recently purchased a used Hasselblad ProShade and wish to make a vignetter for use with this shade. I plan to get some frosted acetate and cut a small hole in the center making the hole slightly larger and larger until I obtain the effect that I desire. Is this a good plan? Any hints?

Paul,

I'm in a similar predicament with a Lindhall shade. I haven't had a chance to make my own vignetter, but I've been studying the Cokins I already have. Cokin makes vignetters by painting on clear plastic. The center is left clear and squiggly lines are painted more or less radially out from the clear area. Cokin's "Spot in Color" uses white paint, and the clear area has a sharp edge, as if the plastic had been masked before painting. This filter has very little effect on the brightness of the image, and even diffuses the image within the clear area at large aperatures.

The "Gray Spot" vignetters use gray paint, and the edge of the clear area is more uneven, with lines stopping at different distances from the center. I like this effect better than the hard edge above. There are two filters of this type with one having darker paint and lines closer together than the other. These filters make the edges and corners darker than the center.

I'm assuming one could also etch the plastic surface with a dremel tool. I'm hoping to try some of these techniques once winter arrives in earnest.

Hope this helps a little,

I have recently discovered that Sailwind makes a magnetic adapter for the Hasselblad ProShade which allow one to use Leon high key and low key vignetter sets. For a catalog, you can call Sailwind at 1-800-868-3686.

A piece of thin card with an oval hole in it. It works. If you don't like the effect throw it away and make another one. Stick with larger apertures if possible.
