Why don't digital cameras need color filters?

When the light is too strong, the sensitivity can be reduced, such as shooting with the lowest ISO. The ISO of traditional film is fixed unless the film is changed. But the ISO (sensitivity) of digital cameras can be adjusted.

Of course, you can also adjust exposure by adjusting shutter speed and aperture at the same time.

By setting in the menu, the shooting time can be displayed on the photo. Please refer to the camera manual for details.

Using macro scene mode, you can shoot small parts as subtle as watch parts at close range. The recent focusing distance of Nikon P90 camera can reach 1cm.

Nikon P90 lens is a three-stage telescope, so adding a UV lens is definitely not possible, and there is no need to add it.
