"let there be light"

This month's photo challenge was the use of light. The assignment is to post two or three pictures where "light takes center stage and commands your attention". That leaves the door wide open for me, and also does not mean there is a chance that I can post only a few pictures. So sorry to continue to be non-compliant on the Personal Photo Challenge. 
The first two pictures were taken in my yard one evening a few years ago. Honestly, the pictures were not retouched. This is the way the eerie sky actually appeared following a late afternoon shower.
This next two pictures show how different the sky can look when the sun is behind the clouds. 

And finally these last two shots were taken out of two different windows at the MGM Grand in Las Vegas, at different times of the day. They certainly show what a difference the outside light or lights can make.

All of these photos were taken with my Nikon Coolpix digital camera. If I remember correctly, all of the automatic settings were on for all six pix.
