When shooting from a kayak, the combination of moving water and your own movement can lead to blurry photographs. If you use slide film, in addition to your supply of Fuji Velvia or Astia, try the Kodak E200 professional film. Stick to shorter focal length lenses when shooting from a kayak such as a wide angle lens or a standard 50mm. You can also try to brace yourself by leaning your elbows on your front deck while shooting. Take your camera out on rainy, misty or foggy days.
Many people only take pictures when it's a nice sunny day.
With your camera body protected in a plastic bag, shooting in the rain can be enjoyable and affords excellent photo opportunities. Colour saturation improves under overcast conditions and harsh shadows are eliminated, making photographs of trees, forests, seaweed-covered rocks, soggy fellow paddlers and beaches great subject matter. To shoot wildlife on a beach, I try to land my boat down the beach from the animals at a distance that does not disturb them, and set up my tripod onshore or in shallow water. I use a 300mm lens with a 1.4x extender and have had great results with nesting birds, river otters, deer, sea lions, orcas, grizzly and black bears. Always keep the boat close by as it is your escape route when photographing unpredictable animals such as bears.
