Fish is an animal living in the water. It is the best, the most realistic, the most authentic, but for general amateur photography enthusiasts, is unrealistic. Therefore, many people will shoot the fish to shoot in the glass cylinder.
The glass surface of the glass cylinder often produces strong reflectance, so it is not advisable to shoot in bright indoors. When shooting, the artificial light is well illuminated. When using artificial light illumination, it is not possible to take directly to the glass cylinder directly with a flash, and a strong reflected light will be generated if it takes directly to the glass cylinder. The best way is to use high ISO values to take advantage of the show in the fish tank. If you have condition, you can use a flash to make indirect flash illumination, that is, when using a flash illumination, first separate the flash with the camera, and perform reflection flashing with a longer flash synchronous cord connection.
Shooting fish in the glass cylinder, should be manual focus, with the photo-filled fish as the focus target, can not be automatically focus with auto focus function, because modern automatic focus cameras adopted by the infrared or ultrasonic active focus system, these two The system is not allowed to focus on the scene behind the glass. The activity in the cylinder has a certain speed at the activity of the water, and the speed of the movement varies depending on the species, so it should determine the shutter speed according to the speed of fish swimming when using the on-site light illumination. General shutter control. Between 1 / 60-1 / 125.
When shooting, the camera is prevented from being reflected in the glass, you can use the black cloth to block the main one after another, only the lens is exposed. Since the surface and the glass surface face the light, there is a strong reflection, and the water absorbs partial light, it can increase 1-2 eV on the basis of the measurement exposure value during shooting.
