How to avoid purple edge in SLR shooting and backlight

The purple edge of the lens is inevitable. No matter the price, focal length and nano-coating amount, there will be purple edges.

Therefore, the purple edge is normal, and you don't have to struggle unless it is visible to the naked eye.

Because the sun or light source behind will be very bright when shooting against the light, the foreground and background will form a Gao Fancha, in which case the purple edge will become more obvious.

1, try not to shoot against the light, especially if you use a lens with a strong purple edge (lens head without nano-coating), and it will be much better to shoot with side light.

2. The purple edge of most lenses is directly related to the aperture size. For example, I am D58 F. 14 from Nikon, and the purple edge will be very powerful at the maximum aperture, and it will be much better if it is reduced to 2.8. Of course, some heads need to be reduced to 4 or 5.6, depending on the situation.

3, later software such as PS LR will have purple edge repair, which can make up for it to a great extent.

Finally, it is normal to have a suitable purple edge. Just because you can see the purple edge when you zoom in to 100%, don't think it's a bad shot or a problem with the lens. . As long as he is invisible to the naked eye, ignore him.
