Abstract in Red and Yellow

...Couldn't think what else to call it. Beautiful late summer's day today and during the morning I noticed the light on the fruitbowl out on the table on the deck so out with the camera. I won't explain what happened, except that it wasn't either (a) A Hydrogen Bomb or (b) Photoshop. Can anybody tell me how I did it. Answer tomorrow.

Hint: I think I have already mentioned the technique , a couple of weeks ago!!
