wibhi2, I usually zoom in close enough to see the pixels, and stay inside the "transition line." You can also add grain with the filter "grain." After I have merged the layers, I usually use the airbrush blur tool, at about 25% to soften the edges. I'm lucky in that my camera takes pictures at 2272 x 1704, at 180 pixels/ inch. When I desaturate, I don't go to grayscale. Instead, I use Image- Adjust- Hue & Saturation at -100. That way, when you pirnt, your printer is still receiving an RGB or CMYK image, usually leaving the print with a neutral hue. At least, that's what works on my printer ( Epson Stylus Photo 820 ). I had to do 3 semesters of photo (B & W) so I like to stay away from the burn & dodge tools (too many darkroom nightmares !) I love playing with Photoshop, don't you ? It gives my older models life, and a reason for completing those on which I'm working ! Thank you, friend. Pix.
