When you make a photograph, you are taking the time to do a number of things. It might be scouting out a particular location, determining the ideal time of day, and weather conditions. Are you going to include people? Are you going to use film, yes people still use film. How are you going to crop the image, What sort of post-production effort goes into making the final image? And, in my opinion, are you going to print it and hang it on the wall? At this point, it is a photograph. It is art.
Now, when you take a picture, you are just recording what you see perhaps without much thought. Just a quick grab of the moment. But is it really reality? Is it really how you perceived what you are seeing and how you choose to capture that particular moment? You are creating more or less at a subconscious level, but still, you are trying to capture what you want to see, and not all of the “reality”. So does that make it a photograph?
In my humble opinion, it becomes a photograph when you get home and look at it and decide that it could/should have some work done to it to somehow improve the image and perhaps turn it into something to hang on the wall.
In a simple sentence, we share images and pictures via social media, and we hand photographs on walls.
