I don't think that a screenshot is a photograph, of course it is an image but that doesn't mean that it is a photograph. A photograph is taken by using light from some source from the environment outside. A screenshot uses the data that are displayed in the monitor. Am i correct?
A screenshot is a record of data (the image data of what was being sent to the screen at a particular moment). A photograph is made by capturing light in the real world. If you were to point a camera at a computer screen and take a photo, that would be a photograph. A screenshot never leaves the digital realm, while a photograph involves the “analog” medium of light
You are right. Both a screenshot and a photograph are images, that is visible impressions obtained by a device, or displayed on a computer or video screen.
But a photograph is always a picture made using a camera.
And a screenshot is an image of the data displayed on the screen of a computer or mobile device.
Not correct many photographic images are made not using a camera, for instance: laying an object on a piece of photographic paper then exposing it to light, the silhouette of the image is captured on the paper. Man Ray experimented with this style along with many other early photographers/artists. Pin holes in walls making huge images on interior walls are not technically camera’s, there are many examples of photographic images being made not using a camera. I think a screenshot is as valid as these.
