Daily Photo Tip

Try photographing motion in as many ways as you can - motion can add a sense of depth and timelessness to a photograph, and can help lead a viewer's eye around the composition. (First published Aug 27, 2009)

26.Sep.10Never let underwater photography interfere with safe diving or snorkelling practices. Chasing a photo underwater can distract you from watching for dangerous situations or keeping an eye on your partners or safety gear. Stay safe!

25.Sep.10Deleted data often stays unperturbed on a data drive until it is overwritten or formatted. If you accidentally delete a critical photo, stop using the drive immediately and take it to a technician to see if the data can be recovered.

24.Sep.10Especially in hot, humid climates, load your camera into its underwater housing in a cool (preferably air-conditioned) room. Cooler air tends to be drier, and having a case full of dry air will reduce problems due to fogging.

23.Sep.10You can dry and reuse silica gel packets, the small paper packages that you may use to keep camera equipment, prints and film dry. Just put the packet in a conventional oven on the lowest possible heat for a number of hours.

22.Sep.10Online photo storage can be a handy way of storing or backing up photos while home or traveling. This method of storage is very bandwidth-intensive, however, and will only work in locations with access to a fast Internet connection.

21.Sep.10Consider the shape of a sensor when comparing it to the 35mm frame size (as is commonly done when judging sensor sizes). A different side length ratio will produce a different angle of view because of its shape, making a simple multiplication factor impossible.

20.Sep.10Murky water can trick autofocus systems, as they will find focus on suspended sediment instead of your intended subject. When focussing underwater, try to get close to your subject and, if possible, set the focus limiter on your lens.

19.Sep.10An APS-H sensor is 28.7mm x 19mm, or about 545 square mm. This is 63% the area of a full-frame sensor. It has a 3:2 side ratio and a crop factor of 1.3. The sensor is found in some digital SLR cameras, but is an uncommon format.

18.Sep.10Don't use compressed air to clean your camera's sensor or lens. Some compressed air contains a sticky propellant, which could be difficult and expensive to remove. Use pure compressed carbon dioxide or a blower brush instead.

17.Sep.10Most cameras use battery power to keep the mirror locked up or the shutter open. Keep in mind that long exposures, or exposures using mirror lock with a timed lead-up, will drain the battery quickly!

16.Sep.10In addition to a dissectant pack, some photographers put a small sponge in the underwater housing with their camera. In addition to providing more flotation (in bag-type cases only) the sponge will seep up any water from a minor leak, keeping it away from the camera.

15.Sep.10As water gets deeper, it filters out more and more colour from sunlight. Warm colours are filtered out in shallower water, making natural sunlight at depth appear strongly blue and violet.

14.Sep.10It is often easier to keep your camera dry in windy, rainy weather than in straight rain. Not only does the wind dry much of the water, but by keeping your camera equipment on the lee side of your body, you can protect it much like it was under a roof.

13.Sep.10A Four Thirds System sensor is 17.3mm x 13mm, or about 225 square mm. This is 26% the area of a full-frame sensor. It has a 4:3 side ratio and a crop factor of 2. The sensor is found in some digital SLR cameras and compact system cameras.

12.Sep.10Some high-end live-view camera systems allow precise focussing by zooming the image on the screen to 100%. This is often clumsier than focussing through the lens, but produces excellent results.
