I had never asked me this before, so now that I have to I really don't know which is. I began thinking in Smart phones, Smart TV, computers, tablets that are stuff I use and actually almost everybody does, but I don't feel that one of these is my favourite. I thought a lot about what I should write and finally concluded (with my teacher's help) that the camera is the chosen one.
I don't have an own camera, but I have a cellphone and my cellphone contains a camera and maybe this can make you think "so her favourite divice is the cell phone" but I don't really like its other functions.
The reason why I like it is because I'm a observer person and in a photo you can save every detail even those that you couldn't see before, also I like because photos let me see how people was when they were younger or see how my ancestors were.
they aren't my ancestors, it's just a picture from google
I think that if cameras didn't exist life wouldn't have memories or maybe everything would be draws but that would never be the same, and live action films wouldn't exist neither! Oh no! that would be horrible! Because all began with photos. Also the camera has been important in science because it allows to show new discoveries like in astronomy, zoology, geography and more.
I just write some examples but as you can see camera is not just a memories keeper it's a really good invention.
