In the Galapagos Islands (which are on the equator) the sun can be very harsh, especially at midday. It tends to wash out landscape photos.
Making use of a small add-on, called a polarizing filter will improve your photos dramatically. Note: you will need a dSLR camera to use a polarizing camera.
As an example, we took a photo at Las Grietas. It was just before noon on the same day (see image below the video). The difference is huge: better color saturation and less (almost no) reflection. Check the video for more information.
