Light pollution is a pressing issue for photographers, especially those shooting at night. Light pollution is caused by artificial light, such as street lamps, which can wash out the night sky and reduce the detail in stars. Light pollution filters are a solution to this issue, as they reduce light pollution in images by blocking out specific colours and wavelengths of light.
Light pollution filters are mostly used in astrophotography to reduce sky brightness and improve the contrast between the sky and the target object. They are also useful for cityscape photographers who want to reduce the orange or yellow glow in their nighttime photos.
There are two main types of light pollution filters: broadband filters and narrowband filters. Broadband filters are better for galaxies, star clusters, and reflection nebulae, as they help retain natural colours. Narrowband filters are more suitable for emission nebulae and supernova remnants.
Light pollution filters can be attached to the camera in various ways, such as being screwed on to the front of the lens, clipped inside the camera body, or inserted into a filter holder.
While light pollution filters can be beneficial in certain situations, they also have some drawbacks. They can reduce light transmission, resulting in darker images that may require adjustments in shutter speed or ISO. Additionally, low-quality filters can add unwanted tints or artefacts to the images.
Overall, light pollution filters can be a valuable tool for photographers, especially those shooting in light-polluted areas, but it is important to consider the specific needs and equipment when choosing the right filter.

Light pollution filters are designed to block out specific colours, such as the orange and yellow light from streetlights
Light pollution filters are designed to block out specific colours, typically orange and yellow light from streetlights. These colours are produced by sodium-vapour and mercury-vapour lamps, which are common in streetlights. The filters can also block light from low CRI LEDs.
Light pollution filters are available in a few different formats. The first is a screw-on filter, which is the most common type of photography filter. These simply screw into the threaded filter spot on your lens. The second type is a drop-in filter, which is inserted into a compatible drop-in system. The third type is a clip-in filter, which clips in front of the camera sensor.
Light pollution filters can be made from optical glass "enriched" with rare earth elements or with a special glass coating. Didymium filters, which are more affordable, use optical glass enriched with a mixture of praseodymium and neodymium to absorb yellow light from streetlights. More costly narrowband filters and high-end broadband filters are interference filters, which use a multilayer coating to reflect unwanted light.
Light pollution filters can be very useful for astrophotographers and night photographers, as they help to reduce light pollution in images. They can also be beneficial for cityscape photographers who want to cut down on orange or yellow glow in their photos. However, light pollution filters do have some drawbacks. They can lower the light transmission of the lens, resulting in darker images. Additionally, low-quality filters may add a tint or artifacts to the images.
When choosing a light pollution filter, it is important to consider the type of light pollution in your area and the type of camera and lens you are using. Not all filters work well with all types of light pollution or equipment. It is also important to keep in mind that light pollution filters are most effective in reducing light pollution from older streetlights, and may not be as effective against newer LED lights.

Light pollution filters are a great tool for photographers, especially those interested in astro and night photography. They can be used with most cameras and lenses and are designed to reduce light pollution, which is often a problem for photographers, by blocking out specific colours and wavelengths of light.
Light pollution is caused by artificial light, such as street lamps, and can ruin night photos by reducing the detail in the sky and stars. Light pollution filters are specially engineered to cut down on particular wavelengths, blocking out specific colours, usually the orange and red parts of the spectrum, and reducing the light pollution in images.
They are available in a variety of formats, including screw-on, drop-in, and clip-in, and can be used with most camera and lens combinations. However, it is important to note that narrowband filters, which are more aggressive in suppressing light pollution, are not suitable for short focal lenses or cameras that have not been modified for full-spectrum photography.
Light pollution filters are particularly useful for astro and night photographers as they help remove the glow of city lights from night scenes, increasing the clarity of the night sky and giving images a more realistic and natural look. They can also be beneficial for cityscape photographers who want to reduce the orange or yellow glow in their nighttime photos.
While light pollution filters can improve night photography, they do have some drawbacks. They can slightly lower the light transmission of the lens, resulting in darker images that may require adjustments to shutter speed or ISO. Additionally, low-quality filters can add a tint or artifacts to images, and the use of an additional piece of glass can reduce overall image quality.
Overall, light pollution filters can be a valuable tool for photographers, especially those interested in astro and night photography, as they help reduce light pollution and improve the clarity and quality of night images.

They are available in different sizes and formats, such as screw-on, drop-in, or clip-in filters
Light pollution filters are available in various sizes and formats, including screw-on, drop-in, and clip-in filters. Screw-on filters, as the name suggests, are filters that you can screw onto the threaded filter spot on your lens. These are usually the most common and convenient types of filters. However, some people find them inconvenient and prefer other options.
Drop-in filters are another option, but they can be fragile and challenging to transport and use. Resin filters, in particular, can damage the optical quality of your images. Glass drop-in filters are chemically hardened but still fragile, so you must be careful when transporting them to your shoot location.
Clip-in filters are a third option that sits beneath the lens inside the camera body. They are considered a better placement for filtration in the optical train and more cost-effective than large screw-on filters. However, you need to ensure you purchase the correct-sized clip-in filter for your specific camera body. For example, Optolong currently makes clip-in filters for Canon, Nikon, and Sony camera bodies.
When choosing a light pollution filter, it's essential to consider your camera body, lens, and personal preferences. Each type of filter has its advantages and disadvantages, so selecting the right one will depend on your unique needs and use case.
