Nice. Is the first one taken in monochrome, Jack, or does it appear that way
due to lack of contrast?

I incresed the contrast slightly of the fog bow image to make it
easier to see. There was no colour at all to the bow unlike a
rainbow.

The field with tractor is unaltered and appears monochrome even though
it was not.
