I decided to share this photograph with the other users of the site because it's my first effort at producing a "black & white" image from a colour original, and I'm quite pleased with the results.
The image is of a column outside the medieval church in the center of St. Emillion and shows significant erosion and calcification of the limestone.
I figured that the amazing texture would work well in black and white or, at least do it more justice than the colour version.
Basically, I opened my image in GIMP and did the conversion using the colour channels as per the tutorial on this site.
However, I wasn't immediately impressed by the contrast available so I cropped the range (increased the value of the "black" pixel and decreased the value of he "white" pixel).
This made the image much more dynamic. Then I added a sepia/platinum colouring.
I've included the original image so that people can see for themselves.
Although I like the result that I achieved, I'd still like peoples' opinions on how this might be improved, plus any tips or hints on composition.
Many thanks,
Dai.
