D

is for

Dithering - what to choose for the challenge today - will I get a better tilt-shift shot later? Is this the only day the sun will shine and I can get a sun silhouette?

Duvet - for that is what it is. A friend I used to work with always called my days off 'duvet days' and continued to use this term when I worked from home. Now I am retired, every day is a duvet day.

Decision - I have decided to use this as an example of a low key shot. To my understanding that means one light source on the subject and a dark/black background.

Dead good these two challenges (see tags)

Damn - it's not in focus!
