I think photography is really awesome.

Yes, I think photography is great because of how widely used it is.  Science, business, art, film--its uses are myriad.

Do you know hold photography has been around?

I don't, however I know that photography is changing.  It used to be that a negative image on film was used to create a positive image on paper. Now we largely use electronics sensors to produce images with pixels.
