The difference between hard image filter and black-and-white filter

Hello, there is no obvious difference between hard image filter and black and white filter.

Black-and-white filter: Suitable for all subjects and functions: Black-and-white filters are generally divided into four colors: yellow, green, orange and red, which can absorb light with different wavelengths, thus presenting black-and-white photos with different effects. The yellow filter can highlight the contrast of blue shadows and blue sky and white clouds; The green filter can cover the sky and make the outdoor portrait look not pale; Orange filter is suitable for shooting colorful sunrise and sunset; The red filter will deepen the tone of blue sky and sea water and increase the contrast.

The main color of the hard image filter is also black and white, which adds a sense of enrichment to the content told by the photo when shooting, which is no longer just a story, but also full of artistic charm.
