Of course, you can layer it onto the image and blend to get a less intense red filter effect.

Another excellent suggestion. I turns it from a picture of a fern with leaves on it, to a leaf sitting on a fern.

Re: Another color or black & white choice: Filter Question
I'd consider what color is blocked and what is passed through the filter, then work with the luminance to get the effect. So, yes...a red filter would block blue and some green. -p On 9/26/2011 12:19 AM, Larry Colen wrote: On Sep 25, 2011, at 10:05 PM, Paul Sorenson wrote: They're both very nice.

If you load the photo into the Develop module, then look in the LR presets, there's a B&W Red Filter Preset. -- PDML Pentax-Discuss Mail List PDML@pdml.net http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.
