H-Alpha Pass Filter

[leon]

Hi All

I have a question for anyone who may know the answer.

In 1996 i bought a H-Alph Pass Filter to use with my film cameras, and was using Kodak 2415Tec Pan Hypered, with great results whilst using this filter.

Now that Hypered Tec Pan is not available any more is my filter still usefull for other photography, and is the Filter i bought 10 years ago the same as the H-Alpha Filters available today.

The one's available today sepcify that they can be used for either Black and White Film and Digital.

I was just wondering if thre may have changed properties in the filter these days.

Thanks Leon

Leon, as far as I know, a h-Alpha filter is a h-A filter, no matter what it's used for. Only designed to allow/stop certain wavelengths of light. Doesn't matter what you put behind it. (Can be corrected). :D L.
ps. Quality may be better these days.
