Mobile cameras are significantly different than the real cameras (pun intended). They take pictures that are different than the cameras that people like me use.
Often it is far quicker to create a dramatic picture with a mobile camera than regular bigger ones.
REMEMBER THIS: Mobile camera lenses have extremely short focal lengths. The objects near the lens look quite big and decrease in size exponentially as they go farther. This is the cornerstone of your masterpiece.
Mobile cameras see very wide. That is why a group selfie is no sweat at all. For a DSLR or a bigger camera to do the same would need a tripod, often a lens change, and plenty time.
Mobile cameras can go rather near the subject without startling them or creating shadows on them. This makes phones excellent to shoot things up close.
Going near also means you can shoot small things and creatures at some magnification so they look bigger and better; what is known as macro photography in my pretentious circles.
A very wide lens lends the magical power of resolving everything clearly from near to far. Photographers call it depth of field.
And most times a mobile camera expects nothing from its owner. No setups, no settings, no thinking even; just point and click!
Alas! Making art needs a bit more thought. I will come to that in a while. Allow me first to show you a few images from my phone. Do read the captions too.
