Re: [Leica] filter question of a different kind...

But wait !

There's another solution - and its free in Photoshop.
Look at the Channel Mixer function in Photoshop. 
It lets you convert color to B&W  and do filter effects when you convert 
it.

For sepia tone - convert your B&W greyscale to RGB and click Colorize in 
Hue & Saturation. Adjust the sliders until you like it - pick the hue of 
your choice and then adjust the Saturation down to suit.
