About photo parameters

The poster is a studious person! Comparing the original parameters of photos is indeed a good way for novice photographers to learn and improve.

The original information of the photo is recorded by the digital camera and is usually called EXIT information. EXIF (Exchangeable image file format) is the abbreviation of exchangeable image file. It is specially set for photos taken by digital cameras and can record the attribute information and shooting data of digital photos. Such as: shooting time, camera model, aperture, shutter, sensitivity, focal length, etc.

Although your photo has been modified, the original information will not change. Some post-processing software will prompt whether to delete the original information when saving, otherwise it will be deleted.
