Filter Kits

Tip: Filter Sets are three different filters and they are: UV Filter, Circular Polarizer Filter and a Neutral Density Filter. UV Filters absorb ultraviolet rays and gives cleaner, sharper pictures with less haze. It is recommended to leave a UV filter on your camera lens at all times to protect the lens from dust, moisture, scratches, and breakage. Though they can be replaced with other filters. Polarizing Filters are essential for outdoor photography; deepens intensity of blue skies , and reduces or eliminates glare. Neutral Density filters are used anytime you feel you are getting yellow or off white coloring while shooting indoors, mainly under flourescent lighting. Rather than getting this blemishing, it counteracts the effects of florescent light bulbs.

Close Up Filters

Tip: Close-Up Filters only let through photons fully-charged with energy, so your pictures will be sharper and clearer.

Wide Angle for Camera/ Camcorder

Tip: In Photography Wide-angle lenses provide large depth of field, making it simple to have foreground and background in focus. Because they take in such wide areas (angles of view), they are excellent for working in tight spaces, such as building interiors, or close-up group pictures. Most wide angles tend to show distortion, just like when you look into a curved mirror, particularly when a subject is photographed close-up. They are extremely handy when you don’t have time to focus accurately or compose properly, because they take in the whole scene and most of it will be in focus. No photojournalist would be without one. They are also ideal for landscapes, taking in large areas of ground and sky, and travel photography. Sometimes you need to really grab your video audience. You want to thrust them into a situation that they can't ignore. The uncanny sense of reality provided by a wide-angle lens might be just what your video requires. How does this work? By taking in an entire vista in one shot, the viewer's eye is free to roam. All of the detail, all of the encompassing sense of a location, is available to your viewer. Like in real life, the audience must decide what to glance at and focus on. One creative way to use wide-angle shots is to establish a first-person point of view. By cutting wide-angle shots with reverse angles showing someone's face, our experience becomes that person's point of view. In this way, we create a sense of connection between the actor and the audience. The lens enables you to capture a much bigger scene. In addition, by using wide angle, it makes camera movement appear smoother and shakiness to much less apparent. As wide angle greatly increases the overall focal range, you do not have to worry about important parts of your scene being out of focus. The wide-angle lens needn't be a slave to reality, however. Some of the most stunning video comes from errors, or distortion made by a really wide lens. When the corners of the image curl around, and more of the world is visible than your eyes thought possible, the effect is striking and we transcend our normal perception. The wide angle can both represent and overcome the very human limits of our vision.

Telephoto for Camera/ Camcorder

Tip: People who shoot wildlife or surfing competitions use long lenses to bring that distant person or animal up close for a good look. Telephoto lenses let you see the details of something far off. Telephoto lenses flatten perspective. They make different elements in the picture look closer together than they really are. You've seen this in movies where the hero seems to be walking down an incredibly crowded street with people squeezed right up next to him. You get this effect by standing well back and shooting with a long telephoto lens. The magnification of a telephoto can be used for dramatic effect. For example, you may want to shoot a twilight shot that includes the full moon in the background. The moon will appear larger and closer if you shoot with a long lens. You can also zoom in on objects that aren't so far away. While a telephoto lens usually will not focus close enough to be a true macro lens (used for very detailed close-ups), it will often enable you to take interesting close-ups or details. At close range, the shallow depth of field of a telephoto will also help the item stand out from its background. On even normal-sized subjects, you can minimize distracting backgrounds using depth of field. If possible, move your subject away from the background and adjust your focus to soften the background but keep the subject sharp. Manipulating perspective is a useful creative tool. If you want to associate two things that are separated, move back and shoot them with your telephoto. This will make them appear closer together. To be creative, you need to know your equipment, what it can do, and what it can't. The telephoto lens is one of your most creative tools. By learning its characteristics and visual effects, you can use this tool to increase the impact of your videos and/ or pictures.

Tip: It's very important you keep your lenses dust and scratch free.
