Ricoh GXR

Ricoh GXR interchangeable unit camera, previewed: Digital Photography Review: "The new GXR is an interchangeable unit camera system in which lenses are changed by using a slide-in mount system to attach camera units to the body. The lens, image sensor, and image processing engine are integrated into the camera units so the body itself does not contain an image sensor."

Bridge Time | Photoblog 2.0

Bridge Time | Photoblog 2.0: "First I did some tests at 30 seconds to get the exposure right. My plan was to multiply out the exposure time once I had the right f/stop at this shutter speed (the maximum I can set on my Nikon D200 before going to Bulb). Based on what I was seeing in the LCD after exposure, 30 seconds and f/5.0 seemed about right.

Based on the 30 second exposure, I calculated that at f/22, the most stopped-down (smallest opening) of the lens I was using, 8 minutes would be about right."

Golden Gate Sunsets

Golden Gate Sunsets: "This map helps you find spots from which you can see the sun set right in the middle of the Golden Gate Bridge.

Viewed from the Bay Area, the direction of the sunset varies from 240.2° at the Winter Solstice to 300.7° at the Summer Solstice. These bearings are measured in degrees east of true north; in the winter, the sun sets more towards the south, and in the summer it sets more towards the north.

Between the 6th of September and the 4th of April each year, the setting sun can be seen right in the center of the Golden Gate from a series of viewpoints around the central bay. Between the 17th of October and the 23rd of February, for 130 days each winter, the viewpoints march up and back along the East Bay shoreline. The exact spot from which the show can be seen moves by a few hundred feet per day."

The rule of thirds

The rule of thirds | "Rules Are Meant to be Broken

Calling the rule of thirds a 'rule' makes it sound like all photographs that don't follow this approach are pretty much awful and boring. Not the case.

There are thousands of examples the world over of amazing eye-catching photos that do not follow the rule of thirds. Many don't seem to follow any 'rule' at all."

Golden ratio - Wikipedia, the free encyclopedia: "In mathematics and the arts, two quantities are in the golden ratio if the ratio of the sum of the quantities to the larger one equals the ratio of the larger one to the smaller. The golden ratio is an irrational mathematical constant, approximately 1.6180339887.[1] Other names frequently used for the golden ratio are the golden section (Latin: sectio aurea) and golden mean"

golden section - Google Search: "What is the Golden Section, Golden Mean, Golden Spiral, Golden Ratio. How to use them in the photography. Rules of Composition."
Golden Section and Rule of Thirds (Golden Mean, Golden Ratio, Golden Spiral, Golden Proportion, Golden Triangles).: "Golden Triangles
Another rule is the 'Golden Triangles'. It's more convenient for photos with diagonal lines. There are three triangles with corresponding shapes. Just roughly place three subjects with approximate equal sizes in these triangles and this rule would be kept."
