Keyshot is a tutorial for rendering and polishing photographic products.
In advertising photography, lighting is a creative work, which not only embodies the photographer's personality and style, but also relates to the success or failure of a work. The following three examples may inspire you. It is also suitable for the lighting idea of Keyshot rendering.
Case 1

The bottom height of 1 3 flexible boxes is close to the horizontal height of the desktop.
In order to obtain uniform illumination on the countertop background, it is necessary to adjust the pitch and rotation angles of the flexible boxes 1 and No.2, and place black cards on the side of the flexible box 1 near the product to prevent the light of the flexible box from directly illuminating the product.
It is necessary to adjust the distance and angle between the tracing paper, the No.3 soft box and the left reflector, so as to obtain a changing light spot on the mirror reflection surface of the product.
Later, the background color was adjusted to hide the back end of the reflection.

Add a blue filter to the 1 lamp, adjust the index of the lamp after determining the screen aperture, and then turn off the modeling lamp.
In the process of drawing with a cold flashlight, be careful that the flashlight head does not enter the picture. If the light is too scattered, wrap the flashlight head with a black cardboard tube to adjust the gathering and scattering of light, and then measure the conversion time with an exposure meter at the position of the blower, and the actual exposure time will be extended at this value.
During the exposure time, when the flashlight moves back and forth on the light drawing line more times, the bright and dark shapes and transitions of the picture are easier and more natural.
Try to adjust and replace the flashlight back and forth, shoot more and choose the one that is satisfactory.
Later, adjust the contrast and color of the hair dryer and the background. The background of this photo is the result of pulling out a big fault in the color scale.

1 lamp index is stronger than that of No.2 lamp.
The lamp bitmap only describes the relative positions of light sources and accessories, but the modeling effect of each light source is closely related to the distance between the lamp holder, the tracing paper and the subject and the size of the lamp holder, which needs to be carefully adjusted.
Later, the background color and local light and shade were adjusted.
