EV +/-commonly known as exposure compensation, it was originally defined as: when the sensitivity is ISO 100, the aperture coefficient is F1, and the exposure time is 1 second, the exposure is defined as 0, the exposure is reduced by one gear (the shutter time is reduced by half or the aperture is reduced by one gear), and the EV value is increased by 1. Increasing and decreasing exposure compensation depends on adjusting the rocker. The shooting environment is relatively dim and needs to increase brightness. When the flash cannot work, the exposure can be compensated and the exposure can be appropriately increased. ""Piglet saw the wolf's plot and set up a big pot on the stove rack.
