There is an essential difference between a picture and a photo, which is written according to the new spelling Photo not only for Windows 11, 10, ... etc. OS!
The terms image and photo are often used all over the place, although they are definitely not one and the same, but that's not so bad, because it's all too human, like the one I'm going to watch TV with tonight. Here is a brief explanation of the essential difference between picture and photo, or photo.
A picture is usually taken by hand, especially the ones drawn or painted, while a picture is also taken with the hands, but the camera actually creates it.
A picture is the most general term for any representation of a person, an object, or a landscape. It can be a drawing, a painting, or a picture created on a computer. It is a visual representation of an object, a scene, a person, or an abstraction that is created by hand on a surface.
Someone who has talent and devotion, finishing a picture after a while can see their own handcrafted work because it also takes a while to finish, whereas a photo only takes a few minutes or seconds.
2.) The term photo!
Strictly speaking, a photo refers to something captured by a camera. A photo is created specifically by capturing the light from the subject on a light-sensitive medium, originally it was glass plates, then film, today mostly an electronic sensor that stores digital photos. A photo is like a replica of the object, which is why we often speak of photocopies.
Although it is also made by hands, it doesn't take extraordinary talent to take a picture. It can be created in minutes and can be printed on any piece of paper. A camera with a lens is used to take a picture!
3.) Photocopies and image copies!
Photocopying is the process that is used today in a laser desktop printer, as well as a photocopier, or just scan and print!
A picture copy is an imitation of an original picture!
But from here you can really hang yourself!
4.) Addendum: the digital original of a photo / photo!
If the photo is a digital file that is also the original, there is no difference between the original and the copy!
As a rule, the photographers are reluctant to hand over the originals, photos with lower resolution are passed on, the originals with the professional photographers are also over 50MB in size per picture is also a kind of guarantee that you are the owner of the true original !
Conclusion: All photos are pictures, but not all pictures are photos.
