1, clean the ring.

Because platinum is a highly reflective bright material, fingerprints or dust will stick when picking up the ring. If you don't pay attention to such small details before shooting, even if there is only a small dirty spot on the ring after the lens is magnified at high magnification, the fingerprint will not appear, otherwise it will bring great trouble to the computer later, so it is very important to get these details in place before shooting.

2. Fix the ring with soft wax.

Soft sticky wax can be attached to articles at will, which has the functions of support and adhesion, and can be easily removed after use without leaving traces, which is very suitable for expensive jewelry. Will not cause any wear on jewelry, can be fixed at any angle, very safe and convenient. Before shooting, we choose a suitable angle and position, stick a sticky wax the size of a small grain of rice on the surface of the still life stage, and fix the ring on the shooting stage. Viscous wax can be bought in the general lighting market. Imported wax is of good quality and expensive, but it can be used repeatedly.

Step 3 adjust the angle

Highlight the "fire color" with lights.

Shot platinum diamond ring refers to a typical one. The ring itself has smooth surface, matte surface, diamonds and other elements, and the needs of each element should be taken into account when lighting. Because of the strong reflection of the smooth surface, the larger size is used as the main light when selecting the soft mask, and the lamp position is reduced. The larger the ring covered by the soft mask, the more effective it is to avoid the mapping of the surrounding environment, and a side light is added to illuminate the side of the ring.

After the light level is determined, the next step is to find the "fire color" of the diamond. You can fine-tune the angle of the ring or the angle of the plane. Diamonds are very strict about the accuracy of light, and even a little angle will show a completely different "fire color" effect. This is very important to reflect the quality of diamond ring.

Step 4 use homemade tools

Set camera parameters and shoot after accurate metering.

Because of the ring effect, the angles of the two rings are different, so it is necessary to adjust the position and light level of the ring slightly after shooting one. Because of the depth of field, in order to leave more space for digital post-design, it is necessary to shoot the front and back parts of the ring in different parts.

5. Tips

The macro lens has a shallow depth of field. In order to make the whole circle clear, under the same composition, the lens is divided into three focuses: front, middle and back. The exposure value of each shot needs to be exactly the same, which is more convenient for later synthesis.
