Let's see what kind of info we can find out about this cat shot.
TIP: You can also use the shortcut of Command and i to open the Show Inspector window.
A new window will pop-up. Click on the EXIF tab at the top of the window. You can find all kinds of information in this window from the date the photo was taken to white balance, to flash settings.
As you can see, there is a lot of data recorded in every photo you take.
TIP: There are other tabs in this window and they will change depending on the device used to take the photo. Examples include the IPTC tab, which will show for photos taken with a regular camera. The IPTC tab will show any user added info like keywords and copyright info. Photos taken with a cellphone will have a GPS setting, showing where the photo was taken.
Here you can see the different tabs available for two photos. The EXIF data on the left is for a photo taken with a Nikon D5100, on the right is the data from an iPhone photo.
