Can the anti-light filter be used during the day?

Anti-light loss filter is mainly used to shoot starry sky.

The anti-light damage filter filters out the light damage in a specific band emitted by urban high-pressure sodium lamps and mercury lamps through special coating, and at the same time keeps Qualcomm in the emission spectrum band of the nebula, thus darkening the artificial light source and improving the contrast of the starry sky.

Types of anti-light damage filter: UHC > l-pro > light damage filter, but the application of color cast UHC anti-light damage filter:

(1) The effect of UHC is very violent and the color cast is quite serious. It can isolate about 70% of light pollution, but it will also lose a lot of details. If the target is mainly H-α and H-β nebulae, it can actually be considered.

(2)L-Pro and optical loss filter, and the green areas below the star field perform very well. L-Pro built-in filter bulb head is applicable, above 900 (full width), the thin one is more expensive, and the light loss filter is relatively cheaper (about 300). Card colors have built-in filters.

(3) urban photography generally adopts S.H.O narrow-band filter.
