Asahi Pentax Y1 Filter

Does anyone know what type of filter the Asahi Pentax Y1 is?

Thanks,
Glen

Y1 should be a yellow filter for B&W photography.

Thanks, woof. Is it a neutral filter for B&W, or does it produce some sort of effect?

It darkens skies nicely so that clouds show up better. A yellow filter darkens the opposite color on the color wheel, and lightens its own color.

Thank you, Canada_Rockies. Thus, a yellow filter for B&W might act in a similar way that a sky filter acts with color?

Regards,
Glen

PS: What a location you have. I would love to visit the Canadian Rockies. Are you on the Alberta or BC side?

PPS: I see in your information that you are on the BC side...

Here's a nice reference:
