Filters worth considering

Lens filters — whether they’re dropped in at the back-end of a long super-telephoto lens or screw-mounted onto the front of the most common lenses — can be very useful for a variety of photographic purposes and can even save you a lot of money in the event of a lens accident. From colored filters [...]

Protective and uv/haze filters

Basic protective filters, also known as neutral filters, offer no additional protection or filtration for your lens. They are made of pure optical glass and are widely available from various filter manufacturers such as Tiffen and B&W. Note that technically these are not actually filters because they aren’t filtering anything, but they usually are grouped [...]

Skylight and warming filters

A skylight filter helps you moderate what can be too much blue in your image, especially on sunny days with an excessive amount of blue sky. It’s a subtle effect, providing just enough filtration to your image that the color is much better balanced; it is especially effective in a shady area under a cloudless, [...]

This is light that’s just outside of visible red light, where nothing that’s illuminated by thermal radiation can be seen. Infrared filters are very dark, and make the world appear as [...]

Neutral density filters

Neutral density filters

Neutral density filters, often just called Neutral density filters, effectively reduce the amount of light reaching your image sensor, but do not affect the color. Why are they useful, you might wonder? In particularly bright conditions, they are very practical and allow you to shoot longer exposures. For example, if you want to shoot a [...]

Softmat (soft-focus) filters

Softmat (soft-focus) filters

Sometimes it is desirable to gain a soft-focus effect on the parts of your image that surround the subject, but not to be as blurry as you see in a narrow-depth-of-field image. A Softmat, or soft-focus, filter provides this effect using diffracted light, and it is especially useful in certain types of portraits as well [...]
