I just point and shoot it. I use full auto mode. The lenses make all of the difference in the world. I don't know how to use the camera very well and I have never worked in Lightroom or Aperature before, even though I have a copy of Lr. I use the camera for work and to take pics of my kids, but I am new to tank shots.
All of those shots are from full auto and I did nothing by crop them - the 5D does a good job with auto white balance, but some of them are not exposed very well. I am joining a photo group, so I should get better in the future. If I learn anything, I will be sure and share.
