Different image formats store data differently. JPEG compresses images to reduce file size, RAW stores full image data for editing, and HEIC offers modern compression for smaller file sizes. Because of this, a 64GB card may hold around 20,000 JPEG photos, 2,500 RAW photos, or over 40,000 HEIC images. https://clippingexpertasia.com/blog/how-many-photos-can-64gb-hold/
