Fig 1. Captures an event on 1989 in China, Fig 2. Captures an event of people in Syria. Both photographs are political related. Both pictures can bring terror, fear, sorrow and maybe even anger to the viewers. But Fig 3. and Fig 4. shows peace ans natural figures and shapes. The main difference is that , in press photography it is usually very negative and some pictures are cropped so the viewer can focus on the terror. The images on art photography can be a wide shot or a zoomed photo. Sometimes art photography ha more color, so it shows the beauty of the world.
It is ethical and acceptable to alter art photographs, the reason is because it it art. Images could be clearer and more focus to draw the viewers attention. However press photography should never be altered, the reason is because you want the viewer to see the while image at its raw state. If press photography were altered people would start questioning the press, and ask the press what they are trying to hide, or show.

Kertesz is correct with being invisible while taking photographs. Some photographs like press photography, and art photography, the photographer needs to be hidden. If the photographer is hidden it is easier to capture nature because nature wont notice a human taking a photo, nature will just act natural and therefore you can capture its original and undisturbed moment. Same goes with press photography. If photographers are taking pictures of war, there is a high risk for the photographer to be injured or killed. Especially in communist countries like China or North Korea, governments are very sensitive with taking photographs. The communist government might think you are a spy from another country, but at the same time we might just want to take a picture of ancient structures, so therefor we need to be hidden sometimes.

I agree with Henri Cartier-Bresson. He talks about how photography is like painting. You can only capture the moment once. There is no such thing as a retake, or a repaint. Once you have the image captured, it doesn’t just capture the image it captures the moment too. Similar to still painting. Every moment could be every capture of an image.
