camera basics - What are the benefits of Av vs. Tv vs. Manual exposure modes?


So what's the benefit of using one over the other? The way I understand it, in Av or Tv, you only have to adjust the shutter or aperture, and the rest is done automatically for you...is this correct? Is there some advantage shooting with Av/Tv that I just don't know about?



Answer



First, I don't know, which advantages of Av/Tv you don't know about. :-)


For me, these modes are very useful, when I do not have time for full manual setting and I do not want to use full auto mode.


Sometimes for example I need the camera not to choose shutter speed less than 1/250 (when I use my telephoto zoom) but I am sure, the camera will choose acceptable F-number.


When I have camera on tripod and shoot some static objects, I use aperture priority as the time can be 20 seconds, when necessary.


The priority programs give me relative freedom to set only, what I need without need to care about the other settings. So I can better focus on photo itself - composition etc.


Sometimes I also use full manual mode - when I have enough time and want to fully control the camera.
