Why is the brighter the lighting in the studio, the darker the products produced by SLR?

1, it may be that the metering mode of your SLR is set incorrectly, for example, you set matrix metering to spot metering;

2. Although you used automatic metering, you set the exposure compensation to a negative value;

3. Although the exposure is normal, but you feel a little dark, you should increase the exposure compensation value, such as 1EV or 2EV.
