What is the difference between digital and manual photography? The difference is when an image is blown up from film it is blurry, but when it is blown up from a digital it isn't. The quality of film photography...
The quality of film photography is good but when the image is enlarged it tends to have a bit of graininess. When you have dots in a picture and blow it up, it doesn't have any of the grains because it is not made of the same material as the negative.
Well the application they use would really be the editing software after the picture is taken. If the picture was taken with a camera with high mega pixel then it is not going to look very good. So your camera is definitely a part of it, but it doesn't mean that you need a $4000 camera to get a good quality shot. Look at the mega pixels. Stick with known brands like Nikon or Cannon. For example, the camera on your phone only has two mega pixels so when it is blown up, it will not going look good.
