I had even more problems today shooting a PAD. I tried photographing a spinning CD in my mini hifi but that didn't work out. I went into the garden and fired off some abstracts, they were poor. I tried getting some good shots of my cat, Smudge, but she wouldn't pose for me. I took some shots directly at the bulb of my 5 million candle light torch but that looked poor. I even took photos of stagnant water in a candle holder in the garden to no avail. So, back to the fail safe, still life then.
I desaturated the whole photo apart from the red parts of this pen.
I didn't realise this PAD business would be so difficult!
