How many photos can 64GB hold?

Could you elaborate on the specifics of the photos you're asking about? Factors such as the resolution and file format of the photos can significantly impact the number of photos that can be stored on a 64GB storage device. For example, if the photos are high-resolution JPEGs, you may be able to store several thousand photos. However, if the photos are raw files from a professional camera, the number may be significantly lower. Could you provide more details about the type of photos you're referring to?
