Put quite simply your camera aperture is the opening in your camera’s lens that allows differential amounts of light through the lens to the cameras light sensitive sensor behind it. Together with the ISO value and shutter speed of your camera it controls the light exposure used to create your photograph.

The size of your camera aperture is controlled by settings called f/stops. An f/stop can also be likened to the human eye as the iris which controls the size of the eye’s pupil. Similarly the smaller the f/stop value (iris) the larger the camera aperture (pupil) and the more light that passes through the lens to the cameras sensor. The larger the f/stop value the smaller the aperture and the less light passes through..

Digital cameras will allow you to choose from an f/stop range dependent on your camera …

Infrared trail cameras are essentially mobile digital cameras which have a motion detection system that detects a human or animal intruder into an area, and triggers a camera which takes either a series of still images, or video footage.

Primarily designed for hunters to scout deer patterns in a hunting zone, these cameras are now more and more used for wildlife observation.

BBC Countryfile recently featured their Stealth Cam Prowler HD infra red scouting camera, showing how they can be used to great effect to capture footage of elusive animals such as river otters and badgers.

The RHS Chelsea Flower Show coverage on BBC also recommends the use of these infra red cameras for people looking to see who or what is lurking around their garden at night, and suggested they are particularly useful for capturing footage of the nocturnal …

Use every setting you can find

The features built into some cameras nowadays are astounding. One example is extreme ISO speed where you can set the sensitivity of your camera to see light that essentially can’t be seen. The ISO speed in a digital camera is no different to the film speeds we used to use many years ago. Remember from your local supermarket or department store you could buy Kodak 100, 200 or 400 speed film. Well digital doesn’t use film, cameras now come with an ISO speed setting built into them, where you can adjust the sensitivity to suit your needs. This is especially good for parties. Here’s my tip – FREE to you. Turn off the flash at a party and push your ISO button and move it from the standard of 100 or 200 up to …

Unfortunately they do more of a job of “hiding” dust than they do removing it. An expensive investment in a camera like the 5D (Canon EOS) can really hit the pocketbook. It would seem like a shame not to take good care of it like the high precision instrument that it is.

Digital camera cleaning of parts, like the lens and body are relatively easy compared to the delicate task of cleaning camera sensors. This is why extreme care should be taken at anytime you remove the lens from your camera body. A damaged sensor would be a costly repair considering some of the middle end models of d-SLR come in at around $2,000 to $3000. Even if you only purchased a “pro-sumer” model like a Canon Rebel XTi or a Nikon D40 for around $800 or $900. It’s probably …
