I was surprised to come across this frog peaking out from behind some grass a fair distance from the water.  I later learned that this is pretty common as this species occupies a wide range of environments.  The frog remained perfectly still and I only caught sight of him because my attention was drawn to an insect close by.  I sharpened and enhanced the detail in Photoshop and made contrast, shadow and exposure adjustments in Lightroom.  I also added a post-crop vignette to darken the edges and draw attention to the centre of the photograph.
