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

1 The bottom height of No.3 flexible boxes is close to the horizontal height of the desktop.

In order to obtain uniform illumination of the countertop background, it is necessary to adjust the pitch and rotation angles of flexible boxesNo. 1 and No.2, and place black cards on the side of flexible boxNo. 1 close to the product to block the direct illumination of the flexible box lamp on 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 specular 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, determine the aperture of the picture, adjust the index of the lamp, 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, adjust the gathering and scattering of light, and then measure the conversion time with an exposure meter at the position of the hair dryer. The actual exposure time will be extended at this value.

During the exposure time, the more times the flashlight travels back and forth on the light drawing line, the easier and more natural the bright and dark shape and transition of the picture will be.

Try to adjust the method of changing 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 picture is the result of pulling out a big fault on the color scale.

Case 3

The index of 1 lamp 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, tracing paper and the object to be photographed and the size of the lamp holder, which needs to be carefully adjusted.

Later, the background color and local light and shade were adjusted.
