Graduated neutral density filters are often used to add some character to an otherwise boring or dull photo. They help to provide an exposure balance when taking shots in challenging lighting situations. The most frequent effect is changing the vibrancy of the sky in an image. A lot of skies are bright and washed out depending on the time of day an image is taken, so a graduated neutral density filter will give the sky a rich and vibrant blue color.
Neutral Density Filters
Neutral density filters aid in reducing the quantity of light that reaches the camera's sensor. These filters are widely-used when a longer shutter speed is necessary at a particular aperature that would otherwise be unattainable without the filter. Common uses for these filters are smoothing water effects, achieving a shallower depth of field or adding motion blur. Some neutral density filters are recognized to add a slight color cast to your pictures which enables some additional creativity.
Linear/Circular Polarizer Filters
Polarizers are often considered the most critical filter for landscape photography. Similar to polarized sunglasses, these filters will lessen glare and reflections off of water and other surfaces, will lower the contrast between land and sky and will make skies appear deeper blue. It should be considered that these filters considerably decrease the level of light reaching the camera's sensor, so based on the lighting, the color in the sky may turn out looking too dark or possibly a bit uneven. The pros certainly over-shadow the cons though, so just have fun and experiment.
Warming and Cooling Filters
Warming camera filters are the ideal solution for portraits or scenic views. It works by incorporating warmth to varied regions of the image if it is a particular cloudy, grey or shady scene. It's also a great little tool for absorbing the blue color that is produced by an electronic flash, meaning that you can aquire the right indoor shot again and again. Cooling camera lens filters offers you that bit of blue color compensation which can add a very "cool" effect to your images. How this works is by reducing some components of bright light, from items like the sun. You are able to realize a very unique feeling with these filters and really bring your photography to another level.
UV/Haze Filters
UV or haze filters are probably the most regularly ordered filter for the fact that they provide the protection that your camera needs from things like dust, scrapes and wetness. If you own a $2,000 lens, then it is definitely worth spending $25-$50 for one of these filters to safeguard your lens from accidental bumps or drops that would otherwise scratch the lens. You should keep it on your camera all the time for optimum protection. Since most cameras now come with sensors that block out most UV, these filters are also often sought after by older camera model owners since they allow you to get rid of excessive degrees of ultraviolet light and tone down the blush cast.
