Capture the Moment!
Since 2013, I’ve published hundreds of blog posts on all aspects of photography. Some are aimed at helping photographers with their technique, settings, and equipment, but others describe my exhibitions, workshops, and adventures in Africa, Antarctica, and beyond.
Feel free to browse chronologically or click on any category heading for specific content, such as Equipment, Trips or Hints and Tips.

Aperture settings for wildlife photography
The aperture is simply the size of the hole in the lens through which light passes on its way to the sensor, and the principle is similar to that of the shutter speed.
The bigger the aperture, the more light reaches the sensor and therefore the brighter the image (all other things being equal). The smaller the aperture, the less light reaches the sensor and therefore the darker the image.
