I'm Canon 70D, and I shot a street lamp product of about 700*600mm in the studio. It is made of cast aluminum and glass, and the overall definition is not enough.

You don't need M file to shoot these, but AV file (aperture priority) is enough.

Small aperture shooting,

If the light is too dim and the shutter is too low,

You can get on a tripod.

Because there are many glass products in the main body, manual focusing mode is adopted.

ISO sensitivity, always set to the minimum value 100.

The background cloth should not be close to the color of lamps and lanterns, and lamps and lanterns should be highlighted by contrast.

Don't appear in the picture with those messy things around you.

Later, a light and shadow magician or Mito Xiu Xiu was used to increase clarity and sharpen it.

You can also add your own brand watermark.
