The Bower 58mm Filter Kit for Camerasincludes a 58mm UV Filter, a 58mm Circular Polarizer Filter, and a 58mm FLD Fluorescent Filter for Daylight Film. Each filter in this kit fits a lens with 58mm front filter threads and can provide one of three enhancements to your imagery. Additionally, these filters are constructed from optical glass within an aluminum-alloy frame, which protect the front element of a lens from scratches, bumps, or impacts. A filter case that can accommodate all three filters is included for storage and transport.

The Bower 58mm UV Filter is a general use, clear filter designed to absorb ultraviolet light and reduce the bluish cast of daylight. Aside from the reduction of unwanted blue casts, no additional coloration or contrast is created, and adjustments to exposure are not required while using this filter. This UV filter is also useful as a general protective filter to leave on lenses at all times. Such filters help to reduce dust and moisture from reaching your front lens element and provide additional protection in case of drops or situations where scratching could occur.

The Bower 58mm Circular Polarizer Filter helps to reduce reflections and glare by filtering out light that has become polarized due to reflection from a non-metallic surface. The light from the sun naturally becomes partially polarized due to reflecting off electrons in air molecules, causing the light to scatter into what appears as haze. A polarizing filter arranges, and filters, this directionally polarized light perpendicularly to the reflected light, allowing for the absorption of much of this light. This results in a noticeable reduction of glare and reflections from non-metallic surfaces and an increase in the saturation of skies and foliage.

A circular polarizer only differs from a linear polarizer in that it contains a quarter wave plane in addition to the linear polarizing filter. The addition of this quarter wave plane is to circularly polarize the linearly polarized light for the use of auto focus and exposure functions. Due to how the light is broken down and filtered with a linear polarizer, auto focus and exposure accuracy become skewed during use. When the light becomes circularly polarized, it permits the use of these functions.

To prevent internal ghosting and reflections, each glass surface on this circular polarizer includes one layer of anti-reflection coating.

The Bower 58mm FLD Fluorescent Filter for Daylight Film is a color correction filter that is designed to reduce green casts when shooting with daylight film under fluorescent lighting. It is constructed from optical glass for clarity and an aluminum-alloy filter ring is featured for durability while remaining lightweight.

Q: 10. Do I have to configure some features in my Nikon D5000 before I use this flash?

A: The camera has both manual and TTL modes. If you set it to the TTL mode there is nothing required for you to do, the camera and the flash will always communicate with each other to give the best exposure. In manual mode you have the option of selecting the distance that your subject will be at, and the flash will then suggest the best aperture for you to set it at based on that distance.
