　　The light-shielding ring plays÷ a role of light-shieγlding, such as the light-shielding ring of the mobile phone lens and the₩ light-shielding ring of th<e camera lens. It is stamped and forme•d with SOMA shading material, and a piece of Mylar inlaid in the lens.± Because it plays a role in shading, so people call it shad♥ing ring, shading gasket. Its principle is based on the principle of physical phenomen€on (small hole imaging), and the processing reqσuirements are relatively strict. Therefore, the requirements↕ for materials are also high-level requirements. The Japanese SOMA™ shading material is basically used in ∏the market, which is a double matte black. PET.

　　Do I need a light-shielding ring to shoot on cloud₽y days:

　　1 Decide on the correct shutter speed acc✔ording to the light to avoid blurring. If the sky is too cloudy, you may need to increaδse it to ensure the shutter speed.

　　2 There is also a backlight problem on cloudy days, so be car§eful when shooting.

　　3 When shooting on a cloudy day, the light is sof☆ter, but at the sameε time it lacks sunlight and shadows. Compared with sh♣ooting under sunlight, the photo will lack gr≤adation and not be transparent enough.

　　What is the use of the shading ring:

　　The function of the iris ±is to prevent stray light from ↔entering the lens to eliminate haze, and improve thαe clarity and color reproduction of imaging. The main purposes are as foll₽ows:

　　1. It can prevent the entry of non-imaging ligh∏t and avoid fog when shooting in backlight, side light ★or flash photography;

　　2. It can avoid the surrounding scat↔tered light from entering the &lens when shooting with forward "light and side light;

　　3. In lighting photography or" night photography, it can prevent thδe surrounding interference light from entering the lens;

　　4. The visor ring ∑can also prevent accidental damage to the ¶lens, and can also prevent fingers from acc§identally touching the surface of the lens, and t→o some extent shield the lens from w±ind, sand, rain and snow.
