Often, red eyes appear in pictures. Where does this effect come from? In fact, when shooting with a flash, light hits the fundus of the human eye and is reflected. The vascular membrane of the fundus is red. From here and such an effect.
How to avoid red-eye when shooting. If there is not enough light in the room, and your camera has only a built-in flash, then to avoid the red-eye effect, you can cover the flash with something translucent. This material can be, for example, a thin sheet of white paper or a napkin. Of course it should be white, not colored 🙂 This will serve as a kind of diffuser …
Also, many cameras have a special mode that will save you from red eyes. In this mode, the camera fires several quick flashes beforehand. Side light can also get rid of this effect.
I use an external flash on my shooting, in low light. Sometimes it is fixed on the camera, and sometimes I hold it in my hand using synchronizers (hand position with flash up and slightly to the side).
