An image pickup apparatus capable of ensuring the accuracy of a proper main light emission amount. A flash device can change an emission color temperature by changing a ratio of light emission between light sources different in emission color temperature. A photometry unit measures a luminance of light reflected from an object by preliminary light emission of the flash device. It is selected whether to perform second preliminary light emission at a color temperature changed according to at least one of spectral characteristics information of the light source, shooting condition information, and photometric value information obtained by first preliminary light emission, and determine a main light emission amount based on a photometric result obtained by second preliminary light emission, or to determine the main light emission amount based on a photometric result obtained by first preliminary light emission without performing second preliminary light emission.
An image pickup apparatus comprising:
A method of controlling an image pickup apparatus using a flash device that is configurable to change an emission color temperature by changing a ratio of light emission between a plurality of light sources different in emission color temperatures, and a photometry sensor, the method comprising:
