Pro-speak for a digital photograph is "JPEG." The term "JPEG" stands for Joint Photographic Experts Group, which is a widely used method for compressing and storing digital images. When you take a digital photograph, it is typically saved as a JPEG file format.
To confirm this, you can look at the file extension of the digital photograph. In most cases, JPEG files will end with ".jpg" or ".jpeg." Additionally, you can also check the properties or metadata of the image to see the file format.
If the file format of the digital photograph is indeed JPEG, you can confidently use this pro-speak term to refer to it.
