Often the pictures you take with your camera will reflect what interests you. Somebody can look at your photographs and will be able to tell what excites you, and captures your imagination. I believe this is one of the most important things about making photography enjoyable. Even children can take fantastic pictures if it is something that they like, such as a family pet, or favourite activity.
If you are capturing an image of something you really like, and have a passion about, it will not make too much difference whether you are taking that shot with a Fujifilm Finepix L55, or a really expensive digital camera. This is because when you are taking a photo of something you love, you know how to get the best out of it.
However photography lessons can teach you techniques that can help you. They can also give you ideas of things you may not have thought of, and introduce to aspects of photography that you did not realise there were.
It is like any other hobby that you take up, there is always something to learn, but it is important to have fun with it too. By trying different techniques you may stumble across a way of making those pictures you enjoy taking even better.
