Ask the great god to help me analyze the light and shadow of photography and the angle of light. Thank you.

This kind of still life photography usually has its own secrets, especially in the field of professional advertising. Moreover, it uses a variety of light sources to shoot, and different color temperature and exposure ratio of each light source will have different effects, so it is difficult to achieve re-engraving. But just ask the angle of the light source or simply analyze it.

1, the first step is that this picture is composed of several materials, that is to say, if there is any light source conflict, shoot it separately and finally synthesize a photo. Because the wrapping paper and the main body are not clearly separated, it needs to be imaged at one time, and the light source of the lower packaging bag is also placed above the photographer, so the whole photo needs to be imaged at one time.

2. Analysis of light source: The main light source is near the photographer's top, and the high exposure of the right wrapping paper can prove that when placing this light source, it is necessary to pay attention to the main YSL not to reflect light, and the angles of the three parts of the subject should be repeatedly placed; The shadow on the lower part of the right high reflection is not deep, and the right head-up angle should have a fill light with low brightness, and the angle should not be too far to the right, otherwise the subject will reflect light, and the right side of the camera will be more than ten degrees; The wrapping paper and the main body should be in the box, and the filling light will brighten the box, so it needs to be wrapped with black flannel or post-processed; In order to reflect the word MOLLY on the main body, the wrapping paper needs to reflect the light to the main body, and it is impossible to judge whether it is the main light source or the auxiliary light source. If it is a great effort to build a model of the main light source, I think it is good to wrap the paper directly from above with a small downlight. The brightness is higher, and the reflection around the font is too explosive; The fold in the upper right corner indicates that there is a direct light source on the left to form a shadow. Because the left side is flat, this light source can be a little stronger. In order not to reflect light on the main body, a camera is placed.
