7 Digital Camera Predators and How to Keep them at Bay

The Digital Camera has a number of natural predators – things that in just a few seconds could snuff out it's life and render you camera-less. Learn to identify your camera's predators and take a few simple precautions and exercise a little care and you can keep your camera operating at it's potential for years to come (well at least until it's time for an upgrade). You really can never do enough digital camera maintenance.

Here are 7 natural predators of the digital camera and how to avoid them:

1. Sunscreen and Insect Repellent

It is important to protect yourself from the elements of sun and insect bites when shooting outdoors, however some of the things that you'll use to do it can cause your camera harm. Sunscreen is generally oily and insect repellent often contains chemicals that you wouldn't want to get in touch with the more delicate parts of your camera.

The way to limit the impact that these things have on your camera is pretty obvious and largely involves keeping those parts of your body that come into contact with these things clean. Wash your hands in fresh water after applying sunscreen and repellent and you'll go a long way to keeping your camera clean. If you do get your camera greasy make sure you clean it off as quickly as you can.

Lastly – don't fall into the temptation of putting sunscreen and repellent into your camera bag. I know it's tempting so that you don't have to carry another bag – but it's really not worth the risk as a leak could end your camera's life. If you do travel with them together make sure you have a sealed bag for the liquids.

2. Sand

There is nothing that frightens me more than the thought of sand getting into my camera. Cameras have moving parts and to get something as gritty and abrasive as sand into them can quickly put your camera out of action or at least damage it so that you end up with scratches through it.

Ultimately the only protection against sand is not taking your camera to sandy places. Of course this is not particularly feasible and you'll need to do what you can to keep sand and your camera separate.

Sealable bags are great to travel with, cleaning brushes to get those stray grains off your camera can be useful and cleaning clothes are helpful.

Always be particularly aware of your surrounds and things like wind or people kicking balls or throwing Frisbees when you're changing lenses, memory cards and batteries as these are high risk moments that sand just loves to swoop in. Also – learn to think ahead about what lens you might need so that you can change it inside in a more stable environment before hitting the beach.


3. Dust

Like sand, dust is a natural enemy of the digital camera. It's a more subtle attacker in that it generally won't scratch your moving parts – but it is just as damaging, particularly when it works its way into your camera's inner parts and settles on your image sensor.

Once again – wipe your camera down each day, be careful of when and where you change lenses and travel with your camera in a sealed bag.

Also if you have a DSLR consider getting it's image sensor professionally cleaned (or learn to do it yourself – with care) every now and again if you do find marks on your sensor (you'll notice them most at small apertures – to test it, set your camera to it's smallest aperture and shoot at a white wall or ceiling).

4. Moisture/Water

Moisture attacks cameras in numerous ways. At it's most extreme it attacks as water which has the ability to quickly end the life of your camera (I regularly get emails from digital camera owners who've dropped cameras in all kinds of liquids including the ocean, baths, rivers and even toilets). Use you camera's wrist or neck straps to keep your cameras out of water and always be aware of where you put it an how it can be knocked.

A more subtle attacker when it comes to moisture is condensation. Particularly noticeable is when you move from one temperature to another with your camera (for example from air-conditioning to humid ones). Investing in silica gel packs is one way to help with this as they absorb moisture in your camera bag. Some people suggest putting it in a sealed plastic bag when moving between temperatures – this might work well but is not particularly practical in many situations, especially when you have a large camera. Ideally you want to warm your camera up naturally and slowly – it's definitely a challenge. Other than that – wipe off your camera regularly when in humid environments.

5. Salt

While the beach presents photographers with wonderful photographic opportunities it also can be a dangerous place with many digital camera predators – not the least of which is salt which has a habit of getting into your camera and lenses and causing all kinds of problems (including corrosion).

Fight the impact that salt has on your camera by wiping it clean at least once per day while shooting in salty places.

If you have a DSLR use UV filters on your lenses to give an extra level of protection and avoid opening your camera up (to change batteries, memory cards or lenses) as much as possible. When not shooting, keep your camera safely in your camera bag and be particularly aware of positioning yourself in sea spray on windy days.

6. Thieves

Another natural predator of expensive photographic equipment is the thief when you least expect it will swoop in and steal your gear away from you – leaving you feeling frustrated, violated and wondering what you did to deserve it.

Always be aware of where your gear is and how accessible it is to others. Get yourself a camera bag that doesn't scream 'I've got a camera in here' if you can (there are some great brands on the market – I use this Crumpler bag for this reason).

Keep your cameras on your body if in a risky environment, keep your bags zipped up and well fastened, consider having your bag on your front rather than your back in high risk situations, insure your gear and try to be selective and not every travel with too much of it at any one time.

7. Bumps and Drops

The downfall of many cameras comes quite literally when they are dropped or bumped into other hard objects. While some cameras now come with shock proof casings the majority of cameras do not and need to be treated as delicate objects.

Use a padded camera bag or casing (and use it when your camera is not in use, be aware of where you put your camera, be careful when passing it from one person to another etc. Also check your house and contents insurance to see whether it covers accidental damage (many do). It's just common sense really but I'm quite amazed at how often silly accidents end the lives of expensive pieces of equipment.

Good Gear

Hopefully you're feeling a little more prepared to venture out with your digital camera feeling confident at your ability to keep it's natural predators away.

If you're looking for some gear to help you with some of the above you might like to check out some of the camera cleaning products at Amazon and their range of Crumpler Camera Bags which I'm a big fan of.

Dogs Dogs Dogs. Earlier today a friend asked me for some ideas on how to photograph her Dog. I did point her to our How to Photograph Pets tutorial but also thought it might be useful to pull together a few Dog Photographs to give her a little extra inspiration. Here's some of what I came across.

Canon Powershot D10 – Review

Canon PowerShot D10.jpgIt was a touch too cold to dunk this camera — and its operator! — in the surf, so I resorted to a dip in the pool. And, to my surprise, I found that not only did the camera perform successfully but I fell upon a magic way to create stunning new pictures.

But back to the aquatic Canon. Via Olympus.

The latter company has made much of its success with the Tough digicams, successfully operable down to 10 metres underwater. I recently had great fun with the Olympus Tough 8000 and felt it was ideally suited to the Australian lifestyle: outdoors, wet and wild.

Belatedly, Canon has picked up the scent of this success and launched its own go-anywhere digicam: PowerShot D10.

CANON POWERSHOT D10 Features

It's all there: waterproof down to 10 meters, dust proof, shockproof to one meter and able to withstand temps down to minus 10 degrees Centigrade.

In picture terms it can shoot 12.1 megapixel images, sized up to a maximum 4000×3000 pixels, or 34×25cm in print terms. In movies, the camera disappoints: only 640×480 or 320×240 pixels at 30 fps. Surely, for a camera selling close to $600 you could expect near-High Def capture.

The zoom is an optically stabilized 3x job, with a 35 SLR equivalent of 35-105mm in range. Straight away I smell trouble: the wide end of 35mm is already very narrow; dunk the digicam and, thanks to water refraction, the zoom range runs from a narrower 50mm at the wide end to 150mm at the tele end. The Olympus was wider: 28mm (underwater 40mm). The message in underwater photography is to use as wide a lens as possible and move as close to the subject as possible: water clarity is rarely perfect.

The body design is unusual: rounded at every edge, it has four corner mounting points so you can attach a sturdy lanyard, according to your needs: you can now shoot left hand, right hand, camera over or under your head.

Viewing is with a 6.4cm LCD screen — no optical finder. The camera, unusually these days, accepts a wide range of memory cards: SD, SSDHC, MMC etc. Also unusually, there is no internal memory.

For metering, you have to rely on either auto or Program AE. Fair enough: if you're shooting underwater, the fewer options the better. To help you along there are a few aids: like scene detection, face detection and blink detection. Besides these, you can choose any of the 17 scene modes accessed through the viewfinder menu.

CANON POWERSHOT D10 Accessories

You can add fun to the D10 by picking up some accessories: like additional shoulder or neck straps and even screw-on face plates to 'militarise' your camera — in camouflage, orange or grey.

There's even a clip on external flash.

Comment

Underwater 16.jpg

As I said earlier, the D10 helped me discover a totally new way of making pictures, freeform, abstract, full of motion, swirls and colour. All you need to indulge in this is the Canon, clear water, bright sunlight, some people and/or colourful objects around you and the opportunities are magic!

Love the camera. But I think the zoom's wide end should have been more like 20mm or less for improved underwater shooting.
