Why we take pictures?

Is it because the world is going so fast ? Is it because we want to record our passage ? Is it because we want to tattoo the thick fabric of time ? Is it because we are alone and we don't want them to forget that ? how much is it worth more ? a photo with blood or a photo with a smile ? could it be that time passes, passes by my side and the only way to catch it is by framing an instant so that we can review it again later ? Could it be that we feel a threat of oblivion ? Could it be that we are altruistic and want to show our world ? squares of various sizes … why will that capture be so shocking ? imagine your existence if you had never seen a photo ? a picture of you when you were a baby, or of your mom when she was young, or when our grandparents were on the face of the earth. Pictures of people who are here.... others who are no longer alive… What is the weight of a photo of someone who is not any more in this world? What is the weight of knowing that what you photograph one day will not be there either? a game where the present becomes the past and affects the future. memories ? maybe nostalgia ? To what extent, part of what is our memory is made upon photographic axes ? What if someone never again took a picture of us or to our environment ? then, what would we see in the mirror ? Will we notice any changes ? Would we remember tomorrow ? could be that we capture images because we know that one day we will lose everything?
