OK somebody asked for Guess What, and as I aim to please(most of the time), this is a starter. I will give one clue and if anybody guesses correctly, I will email that person(s) to let them know. Those that don't guess will have to wait until tomorrow. The clue is, 'Quite a lot of you use this in your photography' Not everybody but a lot. Have fun!!!!!!!!!!!!!!! Thanks for stopping by for a look and for any comments you care to make(guess). May the sun shine down on you, where ever you are. Brilliant sun here again today, but it's pure white in the yard. Think; Extreme Macro.
