The original image shows very little contrast. I mean minimal. You may not even consider taking this shot due to it’s invisibility. When converting to b&w image I like to experiment a little. Increasing the contrast significantly (adding black) brings out the details. This image had an extraordinary amount of texture hidden in the original exposure.. I have to see that to some extent and for which reason I went ahead and took this photo. Bizarre looking tentacles are simply water tracks in the sand. And because the image has become unrecognisable for what it is, scale is also difficult to work out making us think a lot more about what we are seeing.
