Like shadows, reflections also communicate a lot about the subject. But unlike shadows, reflections, many times reveal the details of the subject. Reflections are exciting. You can understand this feeling, when you observe the reactions of a child or a pet dog looking through the reflected image in the mirror. I cannot still forget my first water reflection shot of my friend standing on a very small canal bridge.
The clear reflection of a glass table top gives you tremendous still life pictures. A semi reflective acrylic sheet or mica or any metallic surface provides you reflections of variable strengths. The distorted reflections on the uneven surface provide you a great feel of abstract. If handled carefully these reflections create an immense feel of aesthetics in our pictures. These magical reflections are powerful emotional strength for photography.
There is something called unwanted reflections in photography. These reflections could de-saturate the colours and take away the contrast in a photograph. These reflections could be removed to the desirable extent by using a polarizing filter.
But to me, reflections are natural and they are true to life.
For example, have you ever looked at the reflection of the world around in small dew drop hanging from the tip of a leaf? Have you ever seen and enjoyed the reflection of a tall building in the tinted wind shield of a car as it is approaching the building? Have you ever seen and enjoyed the reflection of your entire new house in the sun glasses of your wife? Have you ever seen and enjoyed the reflection of the automobile lights as they move on a wet road after the rains? Have you ever seen and enjoyed the reflection of your wine glass on the black granite table of your bar counter? Have you ever noticed the distorted and elongated reflections of your entire family on the stainless steel glossy water mug when all of you are dining..?
If you have not seen such beautiful things in life then, there is very little you could do with your camera. Because, reflections prompt you an instinct to photograph even the ordinary things to make it look extra-ordinary.
