Necessities arise from the evolution of human beings or human brains.
With the great advancement in technology, photography cameras have evolved as well. But more than a camera, people now use their mobile phones because mobile phones now have such great tech and their cameras are even better than some cheap photography cameras out there.
If you travel, a selfie stick is one of those things that you cannot do without. In the olden days if I wanted to take a photo of my fiance and I, I used to ask people passing by.
The selfie stick has also taken away the personal contact. So with the improvement in technology, we are more dependent on these gadgets and unfortunately this is taking away the personal contact and conversation opportunities like we had in the past.
With progress comes change. And this is one of the biggest change in the personal photography scene I believe.
