High score! ! Ask how to prevent overexposure when shooting white objects! !

If the contrast of the subject is too strong, there is nothing any camera can do.

The simple way is to try not to overexpose the bright part when shooting, and then adjust it with the "shadow/highlight" function in PS.

Another method is a little more complicated: you can use the method of surrounding exposure to set the EV value span a little larger, take 3 to 5 photos, and then use the HDR synthesis function of PS CS5 to take photos with a wide dynamic range.
