I tried black and white, Bob, but the loss of the yellow light/reflector made, I thought, for a poorer picture. Pasting a b & w version over a colour version and clipping it to reveal the light didn't work, either.

I shot a bit dark to get the texture. Some was lost, however, once the picture was brightened up.

Thanks for the kind words.

He says things better than I could, too, Sarah. And they're perceptive. HIs fluency is greater than mine, too -- I think I've spent too great a part of my life writing about the results of statistical tests.

But all comments are welcome; over the years I've learned a lot from your, Bob's, and everybody else's comments.

Thanks, William.

Thanks, Jaap.
