Should You Use a CPL and UV Filter Together?
In the world of photography, filters can be a photographer's best friend or worst nightmare. They can help you achieve stunning results, but they can also introduce unwanted artifacts and degrade image quality if not used properly. Two of the most common filters are the UV filter and the CPL filter. But can you use both of them together?
What are UV and CPL Filters?
- UV Filters: UV filters are designed to block ultraviolet light, which is invisible to the human eye but can cause haze and reduce image sharpness. They are especially useful in high-altitude or seaside locations where UV rays are more prevalent.

- CPL Filters: CPL filters, or circular polarizing filters, are used to manipulate the way light interacts with objects. They can reduce reflections, enhance color saturation, and create a more dramatic sky by deepening the blues and deepening the contrast between the sky and clouds.

Can You Use a CPL and UV Filter Together?
Yes, it is possible to use a CPL and UV filter together. However, there are some potential drawbacks to doing so.
Potential Drawbacks of Stacking Filters
-
Increased Light Loss: Adding multiple filters to your lens can reduce the amount of light that reaches the sensor, which can affect exposure and image quality.
-
Reduced Image Quality: Multiple layers of glass can introduce unwanted artifacts such as chromatic aberration, flare, and ghosting.
-
Vignetting: Wide-angle lenses may experience vignetting, or darkening around the edges of the frame, when stacked filters are used.
When to Use a CPL and UV Filter Together
Despite the potential drawbacks, there are some situations where using a CPL and UV filter together can be beneficial.
-
Protecting Expensive Lenses: If you have an expensive lens that you want to protect from scratches and dust, using a UV filter can provide an extra layer of protection.
-
Enhancing Landscape Photos: When shooting outdoors in bright conditions, using both a CPL and UV filter can help to reduce haze, improve color saturation, and create a more dramatic sky.
-
Specific Shooting Scenarios: In certain shooting scenarios, such as when shooting in water or around water reflections, using a CPL and UV filter can help to reduce reflections and improve image quality.
When Not to Use a CPL and UV Filter Together
-
Low-Light Photography: When shooting in low-light conditions, it is best to avoid stacking filters as this can significantly reduce the amount of light that reaches the sensor.
-
Closed-Up Photography: When shooting close-up or macro photography, it is best to avoid using a CPL filter as it can introduce unwanted reflections and artifacts.
-
Indoor Photography: Unless you are specifically trying to reduce haze or reflections from indoor light sources, it is usually unnecessary to use a CPL filter indoors.
Conclusion
The decision of whether or not to use a CPL and UV filter together depends on your specific needs and shooting conditions. If you are concerned about haze or reflections, but also want to protect your lens from scratches and dust, using both filters can be a good option. However, if you are shooting in low-light conditions or in situations where reflections are not a major concern, then it is best to avoid stacking filters. Ultimately, the best way to decide is to experiment with both filters and see which combination works best for you.
Additional Tips
-
Invest in high-quality filters: Cheap filters can introduce more artifacts and degrade image quality than high-quality filters.
-
Clean your filters regularly: Dirt, dust, and fingerprints can easily scratch your filters and reduce their effectiveness.
-
Remove filters when not in use: Leaving filters on your lens when not in use can increase the risk of scratches and damage.
By following these tips, you can use filters to enhance your images without compromising their quality.
