Crop image to pseudo-widescreen. Superimpose onto a grey background. Use the gradient tool in photoshop to blend from black to transparent from the edge of the pic into the grey.
I went to visit your gallery after seeing your rose and must tell you at least in one on the photo areas how much I enjoy your work. I won't comment on each one to tie up our time but know that it's been a fun venture for me to see your photos. Thanks for sharing your talent! - Patty
