Sounds about the right factor for a red filter in daylight. Looks like it too.

Alan, I remember when I had a collection of colored filters to screw on my lens for b&w film. How I now enjoy adding filters in PhotoShop!

Nice shot.

I still have my (Series 6) filters for B&W photography, but I haven't used them in years.

Nice. I quite often will put a red#2 on the camera if an outside shot is for BW, or might be...sometimes on rare occasions I will use a yellow, alone or in combination.. Take both shots with and without. PS CANNOT emulate to the same degree an actual #2 Red filter for BW work. Close, but no ceegar. When using those filters for BW I shoot in RAW and color, then convert in post.

After having looked at the spectral transmission of yellow and red filters, I don't see how the yellow filter changes things much if the camera is already wearing a red filter. in the part of the spectrum the red filter transmits significant (> 1%) light, the yelllow filter is essentially clear. My figures for the yellow filter showing essentially a flat transmission. I suppose the remaining 8 percent transmission loss is from the reflections from two uncoated glass surfaces of the sample. Aside from an attenuation of 1/8 stop or so, do you find any difference when using the red filter alone vs. using it with the yellow filter? I never did, either visually or photographically, even before I knew the transmission characteristics of these filters.
