So after years of wanting one, I finally have a DSLR. I got a Canon T3i kit from Costco (it came with a 18-55 and 55-250 lenses). I know I could have gotten the T4i for about the same price if I looked around on line, but after so long hemming and hawing, I just wanted to get it. The new camera became a necessity because we're going to Hawaii for Labor Day. And since I wanted to be comfortable with where all the buttons were, and how to change settings quickly, I had to get it before my WDW trip in 2 1/2 weeks so I could use WDW as a training ground. My last two cameras have been a Canon S5 and the S1, and I've spent the last 8 or so years becoming comfortable with shooting in Tv and Av priority modes. I have Understanding Exposure. But there are still a lot of the other camera features I haven't spent that much time playing around, and feel way over my head with such as metering modes, manually choosing focal points, flash settings, etc. Any good resources for learning about those? Also, as I'm wandering around my house taking pictures of random things in my Disney collection, I've been wondering what is preferable, as far as forming good and bad habits. Using the flash, with lower ISO, or no flash but at higher ISO (800 or 1600)? With the S-series, the graininess at anything 800 or above made flash a necessity if I couldn't get more light in the room. But the flash makes things seem less natural (I'm guessing I need to learn more about modifying flash settings). I prefer the shots I've taken at the higher ISO with the ambient light, but I don't want to be one of those people that is using my equipment wrong. Lastly, the camera is quite loud and I'm wondering if I'm going to get a lot of nasty looks because of it when taking pictures of the shows at the theme parks? Obviously, getting a quieter camera isn't an option right now, but do you try to sit in certain spots where your less likely to have neighbors, leave the camera in the bag, don't worry about the noise?
