I have always used a point and shoot digital camera, but my pictures were lacking some of that finesse that is apparent when using higher end cameras. I was really confused when it came to upgrading to a better camera, but after much research I finally decided that I was comfortable enough in buying a digital SLR camera. Unlike point and shoot cameras, dSLR cameras have many settings that can make your pictures volumes better! You can control how much light comes into the lense (comes in handy when you're in bright areas or dark areas), you can control the flash, and you can switch between lenses to create interesting shots (wideangle or even fish-eye lenses).
There are so many guides both online and in bookstores dedicated to this camera. It is consistently getting great reviews from amateurs to professional photographers. My pictures have greatly improved in quality since getting this camera. And like with any new electronic there is a learning curve, but just remember to be patient and invest actual time into learning your product. Finally, trial and error is really the best way to learn so go ahead and get snap happy.
