What is the shooting method and post-processing of this photo?

As my friend said, the aperture is around 4.0. If the aperture is too small, it is not easy to obtain a shallow depth of field as shown in the figure.

For accurate exposure, you can use Av mode to lock the aperture and let the camera automatically control the shutter time. Because you are shooting a still life, there will be no ambiguity. To ensure the shooting effect, remember to fix the camera with a tripod.

The focal length of the photo in this picture may be 85 mm

This picture uses two lights, and one hits it. Notice the shadow under the black handle.

The one in the upper right corner is the main light source, leaving the shadow of the pot at the left rear.

In order to ensure the brightness balance on the left side of the pot, a white reflector is used, and you can see the shadow of the white reflector on the glass on the left side of the pot.

Spot metering can be used, and the metering should be in the stainless steel position in the middle of the pot. If spot metering is selected, but the metering point is aimed at the black handle or cover, the picture will be overexposed. To measure the light in the middle of the picture, it is also good to take a tea table.

Measuring the position of the stainless steel ring will lead to underexposure of the picture. Adjust the exposure compensation of+1EV or +2EV to obtain a high-quality picture effect.

Also, if you have a polarizer, you can filter out part of the reflection on the glass surface to increase the transparency of the shot. But since I'm a novice, I don't need it.

Post-image processing methods: increase image contrast, increase color saturation, and appropriately increase the saturation of point green and yellow.

Adjust the curve to make the visual impact of the picture stronger.

All right, that's it.

It is not difficult to get the effect in the picture. Practice more and I believe you will make great progress soon. Photography is such a process of constant thinking and constant tempering.

I hope my answer can help you.
