Daily Photo Tip

Linear polarizers don't interfere with contrast detect autofocus systems the way they do with phase detect autofocus systems. Since the system is only sensing pixel difference values, the light coming to the sensor can be polarized by any method. (First published Jul 30, 2011)

25.Nov.10If you're doing a lot of shooting on location or in studio, you may wish to set up a wireless connection to a computer and upload the photographs in real time. Not only will you never have to change your memory card, you can open and check the resulting photos on a calibrated monitor right after shooting them.

24.Nov.10Two photos that have the same tonal range may appear very different. Depending on where the balance of the brightness values lie, for example, a photo with a very wide tonal range can appear very high contrast or very dull.

23.Nov.10If your camera is menu-driven, take advantage of any user-programmable functions that allow you to program certain buttons. By reducing the number of button pushes for often-used functions, you will be able to make photographs quickly and easily.

22.Nov.10Internal photo modes will likely affect the amount of sharpening applied to the JPEG output (but not the RAW photograph). Landscape mode, for example, will probably sharpen a photo more than portrait mode.

21.Nov.10Underwater housings can fog up on the inside when they are brought out of the water, particularly where droplets of water on the outside of the case cool the humid air inside the case. In warm water, this fogging will go away within a couple of minutes of the case being resubmerged.

20.Nov.10In some remote areas, you may be required to travel as part of a group for wildlife safety reasons. Plan ahead, and always make sure that you will be accompanied by enough people to make your journey possible.

19.Nov.10If you're employing any kind of complex real-time upload technology or other non-standard data storage technique for a particular photo shoot, be sure that the system works in a dry run before the actual shoot starts. The will help avoid data loss and embarrassing situations.

18.Nov.10Remember that water filters the colour and limits the intensity of light. Deep or far away objects (even if they are near the surface) will usually appear bluer and darker than objects that are close by. Murkier water can take a greener tinge.

17.Nov.10If you travel for business or other commitments, try to bring a small camera with you to make photographs in your downtime. This can be a great way of spending time out-of-town, and a great opportunity to photograph subjects you might otherwise miss.

16.Nov.10In some remote areas, like near industry outposts, you may have to take safety courses in order to venture beyond the limits of the human-controlled area. Take the courses before you go, or allow time to complete them once you arrive.

15.Nov.10Everywhere you go, try to see as a photographer. Even without your camera in your hand, think about how you would photograph a certain object or scene – from lens choice, to composition, to exposure, to post-processing. This will help you think along these lines later, when you do have a camera.

14.Nov.10Compared to camera equipment, digital memory is cheap. Hard drives, flash cards, and other storage media are inexpensive enough to justify multiple backups of important work.

13.Nov.10When using a digital still camera as a movie camera, keep in mind that many controls found on true video cameras will not be available. Many manual controls, particularly manual focusing and aperture controls, will probably be automatically controlled by the camera.

12.Nov.10Aerial photography from a helicopter is a convenient way to see the landscape, but is highly expensive. Helicopters can go anywhere quickly and can hover while you make pictures, but often cost thousands of dollars per hour.

11.Nov.10If possible, store the locations of intended photography sites in a portable GPS before going up to do aerial photography. By following the GPS, the pilot will be able to reach locations faster, giving you more time to take pictures.
