How much is the general ios for food photography and how to adjust the shutter aperture?

General sensitivity settings should be set according to weather or light conditions.

1, ISO is set to: 100-300 in sunny days.

2. ISO is set to 200-400 in rainy days.

3. At night or in a very dark environment, ISO is set to 100+ flash or manual lighting. At this time, you can use a tripod or a fixture to fix the camera to reduce the ISO value.

4. Scenes such as parties/concerts/dances are easy to cause insufficient light. You can use ISO800 or low-value flash.

According to the environment, choose the lowest ISO sensitivity to shoot, if it is not a very dark environment, it is generally best not to exceed 800; When shooting at night or in an environment where the ISO value needs to be improved for a long time, the noise will inevitably increase. In this case, the noise reduction function of SLR is usually turned on to reduce the noise, or the noise of the picture is reduced through post-processing.
