The prompt for 4th December 2016 is: Artificial Light
It is very simple. Your image must be light by artificial light only. No sunlight, no daylight! Think lamps, candles, street lights, fire, torch (flashlight for the Murricans) etc. The joy of artificial light is that you can control it more, the amount, the angle etc and however it brings with it potential problems. Extremes of light and dark, colour tones that make skin look a weird colour, bright spots, strange and unflattering shadows and so on. However many of these can also be worked to your advantage. So draw those curtains and get working…
The prompt is published here on the site mid month, which will give people approximately 2 weeks to work on their idea before linking in, on the 1st weekend of the month. The prompt is completely optional and you can link in as normal on that weekend whether you have used the prompt or not. The usual Sinful Sunday rules will, of course, apply. Please make sure you have read them recently so that you are fully aware of what is and is not allowed.
As always interpret as you wish, or disregard altogether and do you own thing.
