One of the most irritating part of photographing highly reflective surfaces is the tendency for certain parts to flare and thus over expose.
One common way of reducing the flares is to use a Polarising Filter.
Because of its property, polarising filter is good for capturing details behind a glass window or underneath the water surface.
To use it effectively, firstly screw the filter onto the lens of the camera. Next look through the view finder of the camera and frame the composition. After that, rotate the polarising filter until the least reflections and flare is achieved.
When using Polarising Filter, you should apply some exposure compensation. This is because the polarising filter will block up to 2 f-stops of light. The recommended setting is +2 stops.
However, if you are using the camera’s TTL meter, you need not apply any form of compensation. For these type of cameras, the filter’s effect is being taken into account by the meter.
Polarising filters are one of the most commonly used filters. They are widely available in shops that sell photographic equipments. You should be able to find one that fit the lens size.
