Natural light is my favourite source for illuminating the subject to be photographed, be it portrait, architecture, landscape or sport.
In today’s series of images I thought I’d add some of the settings I used for those of you interested in the technical side of things.
Sometimes sunlight creates extraordinary effects and if you are fortunate enough to have your camera at hand when this takes place, interesting images are possible.
I saw from my office window that the afternoon sum was creating a soft glow surrounding the house across the road. I grabbed my camera, fitted the appropriate lens and stepped out onto our front veranda to make an image. Talk about being ‘Johnny on the spot’ as the saying goes. In the few minutes since seeing the soft glow, a magnificent rainbow had suddenly appeared across the road and the light was extraordinary. Here is the shot made with my zoom set at 12mm, 1/80 sec, f4, ISO 100. Notice that the two steel poles in the right side of the foreground are not perpendicular. This is caused by lens aberration in the optics of an extremely wide angle lens. I chose not to correct this using Photoshop. 
The next image was taken just as the sun set on the Sculpture Garden situate on a hill side just out of Broken Hill in outback New South Wales. With the camera on a tripod and my zoom lens set at 24mm, I made the shot at 1/20th sec at f16, ISO 100.
The sculptures are bathed in natural light , particularly at dawn and sunset.
The main display area in the Goulburn Regional Art Gallery is bathed in natural light courtesy of large skylights situate at salient points in the roof.
The following image, which speaks for itself, was illuminated purely by the light from the skylights that flooded across it. I made this shot using my zooms set at 24mm, 1/80th second at f4, ISO 100.
This final image shows the afternoon light pouring in through the stained glass windows of the ‘Nurses Chapel’ of the old Prince Henry Hospital, perched on the cliffs overlooking Little Bay and the Pacific Ocean in one of Sydney’s southern suburbs.
In this image I’m particularly attracted to the fact that through the lower section of the window, one can see the surf breaking on the rocks at the base of the cliff.
In making this image I again used the zoom set at 24mm , 1/160th sec at f6.3, ISO 100
It will be fun to see what tomorrow’s challenge brings.
Hoo roo for now.
CREAKINGBONES 
the first and the last are my favorites, as you say, seeing the sea through the bottom of the glass, and that rainbow..absolutely exquisite!
I’m so pleased you liked them. I gave a copy of the rainbow to the couple who live across the road. They have it hanging in their family room.
Beautiful. I like the reflection of the stained glass on the floor, too. Your post reminds me of a delightful conversation I had several years ago with an apple genius. He was teaching me how to use some of the advanced editing features of Final Cut Pro. He described a video project he had filmed in natural light and he was just tickled that he and his team listed “God” under the lighting credits.
The Great Architect of the Universe has created many wonders for us to enjoy.
