What is the "bright spot" in photography?

In photography terminology, the word highlight is used in later image processing, which is strictly an artistic term; Overexposure refers to the quality identification of photos.

Highlight means that when a light source shines on an object and then reflects into people's eyes, the brightest point on the object is highlight, not light, but the brightest part on the object.

In art terminology, highlight refers to the brightest point in the picture, which shows the part of the object that directly reflects the light source, and is more common in smooth objects. The dark part will reflect light because of the reflection of the surrounding objects. As a part of the dark part, reflection is generally darker than the deepest middle color in the bright part.

Overexposure refers to the fact that the brightness in the picture is too high and the photo is white due to reasons such as too large aperture and too slow shutter.

In photography, exposure refers to the amount of light allowed to enter the lens and shine on the photosensitive medium (the negative of a film camera or the image sensor of a digital camera) during photography.

"Exposure" can be controlled by the combination of aperture, shutter and sensitivity of photosensitive medium.

Ideally, when the exposure is controlled within a reasonable range, the photos have strong contrast and moderate brightness. Over-exposure will occur when photos are exposed for a long time or due to unexpected reasons or the photographer's personal technical ability is too large.
