In some embodiments of the present application, fig. 2 shows a second flowchart of a photographing method according to an embodiment of the present application, as shown in fig. 2, photographing a target image, including:
step 202, shooting an original image according to a first exposure parameter;
in step 202, an original image is captured by the first exposure parameters, i.e. all areas in the original image are exposed according to the first exposure parameters.
Step 204, determining a first area and a second area in the original image;
wherein the first region and the second region comprise different image features;
