HDR photography, how to make an ingenious work?

Look at the official explanation of HDR first: High-Dynamic image.

Distance (HDR), compared with ordinary images, can provide more dynamic range and image details. According to the LDR (low dynamic) of different exposure time,

Range) image, the final HDR image is synthesized with the best detail LDR image corresponding to each exposure time, which can better reflect the visual effect in the real environment.

The principle of HDR mode in SLR cameras is to take three photos with different exposures: one short, one over and one normal. When synthesizing, the camera will keep the normal exposed part, the dark part of the past one, and the bright part of the missing one, so that the level of this photo will be very rich, which is also conducive to the later processing.

In HDR mode, there are several options, such as nature, standard painting style, smoke painting style, oil painting effect and relief painting effect. Each style has a different purpose. You can try more when shooting, but there may be too many built-in effects, which will be "embarrassing". This requires us to keep the original RAW in ps and synthesize HDR independently.

HDR is a photography method, which is usually used for landscape or architectural photography, and the effect of small aperture and long exposure will be more obvious.
