Trees, Sky, Church, Deer - mono experiments

I'm working on a presentation for our camera club on mono conversion so, while the weather was co-operating this afternoon, Gill and I took a walk around Charlecote park and I took a few photos with the camera set to process a jpg in monochrome.  The two monos are in the xtras,  one from the camera, looks a little washed out perhaps,  and one I did in Lightroom and Silver EFex - looks over processed.  Both monos have a yellow filter setting,  The one in Silver Efex definitely looks the stronger of the two.
