My point is that photographic sharks at a bait station is akin to shooting deer at a salt lick. If you can shoot deer at a salt lick and still feel that you have bragging rights then you can photograph sharks at a bait station and feel good about showing off your photos. It runs counter to the ethics of natural history photography as I subscribe to them, but then I am a bit of a purist.
Photography Ethics
People love to take pictures of animals! And people love to look at pictures of animals. Both these are reasons why this website exists.
But for those who take photographs of animals, its not just a matter of clicking the shutter and happily showing everyone the picture. Whenever someone takes a photograph of an animal it affects the animal in some way. The ethical photographer always considers this impact while he or she is taking the picture.
Most photographers are conscientious and respect the animal that they are photographing. In these cases, the interaction is passive; the photographer takes the picture, quietly withdraws and thats that.
Bad practices
The pressure to get a good picture can cause the photographer to forget or, worse, to deliberately choose to ignore ethical photography guidelines. The most egregious example is when the photographer kills the animal, such as a butterfly or beetle, then poses it in a position to try and pass it off as a photo of a live creature.
A less serious practice is when the photographer physically traps the animal to hold it in a certain pose or to place it in fake surroundings. Is this practice ethical? In rare circumstances, the procedure may be justified if there is a strong case for the educational value of the photograph and if an expert animal handler is supervising the photographer (unless the photographer is an expert).
For example, insects are quite difficult to photograph as they are small and move quickly. Some photographers will capture the specimen and place it in a refrigerator or cold box and then pose the animal which is rendered sluggish by the low temperature. Alternatively, the photographer may use a carbon dioxide source to knock out the bug which will rest on any surface as it is recovering. The insect is unlikely to suffer permanent harm if these procedures are carried out carefully but in most instances, ethics dictate the preferable alternative: to photograph the animal behaving normally in its natural surroundings.
People have been known to throw food to attract animals closer or to cut away vegetation that was in the way of their subject. Whats the point? If in the end, you dont get the perfect picture, surely it is more rewarding to treasure sharing that moment with a truly wild animal and the experience of intimacy with nature.
Best practices
It is best to be quiet and gentle when taking photographs of wild animals. Careful observation and patience, plus a good understanding of the animals behavior and habitat will yield much better photos than barging in and trying all manner of things to attract the animals attention or to get it to move to a more convenient location.
