How to use the camera filter?

The color filter is an accessory lens installed in front of the lens, which can not only prevent the light of a certain wavelength from passing through, but also emphasize the light of a certain wavelength. That is to say, it is a device for filtering light, which is of great value in adjusting light and achieving a certain light effect in photography. However, because the color filter has a certain influence on the performance of the camera lens,

So some people think it's best not to use it. Based on these two reasons, the conclusion is that the color filter should not be used indiscriminately, otherwise it will be counterproductive. Flexible use of color filters, the screen will appear the appropriate expected effect. In addition, if the color filters overlap, the imaging effect of the lens will be reduced, so it is recommended that only two color filters overlap at most.

The imaging process of a digital camera is to convert light into electrical signals. In the process of conversion, bright spots and light from unknown sources have great influence on digital imaging. The development of DHG coating adopts special multilayer and different coating technologies, which minimizes the adverse effects of glare and unknown light on imaging, and combines the above three characteristics with the inking treatment along the lens edge and the design of no reflected light on the ultra-narrow frame. Marumi DHG coating filter fully meets the requirements of digital conversion imaging.
