just picked up understanding exposure
This is really a great book for anyone starting out. Admittedly, I have to read a couple of parts a few times to truly understand what he is talking about, but after a little, it all starts to make senseI am about half way done and this has not been covered yet, (I skimmed the rest and did not see it) so I will ask you guys:It seems like the way to make a "correct" exposure is to set the aperture, the shutter speed and get a ISO reading to see if you need to adjust. BUT, what if you are taking a picture of a 2.5 year old and a 3 month old. OR, if you are at a sporting event and you want to capture that moment.How can you adjust your camera settings that quickly to get what you wantETA: Thanks Parmcat for the response. I started reading more today and the first section was dealing with shutter speed as things are in motion

Another one:What makes a lens good vs. bad. I have gone to some photography forums and many have said that the stock lens (18-105) is not good and not worth the price to have it bundled with the body. How can you determine what is good? Why is the lens that JoJo posted (I think it is a 50MM fixed lens) so good. This has not been covered in the book either. Does it have to do with the lower aperture
