There is an Ap for that.

I can not draw a half eaten zebra for many reasons and that is why I am showing this dead zebra with the legs up in the air.
There is an old saying if you go on a trip or vacation and do not have any photos then it did not happen. I wonder these days what effect smart phones is having on camera sales and will we be the last generation to know what a camera is? 
I used to be a full fledged professional photographer, used all sorts of cameras from 35 mm all the way up to a 4X5 Graflex view cameras, like the ones you see in the old movies (really old movies).  Unlike the roll film cameras, a 4X5 view camera camera used sheet film and each negative was 4 inch by 5 inches. The viewer was the same place that the film cartridge went and each film cartridge held two sheet of film.  The thing weighed about 5 pounds and unlike the new digital cameras you did not waste very many shots.  Times have changed and now days if a person has a smart phone they also have a movie camera, a still camera, a music box, access to the internet and one day they may also serve you lunch.
