Just another day in my usual Greenwich spot. The tide is moving out and you can catch odd lighter lines in the moving water showing the movement outwards. I've always liked this effect but don't know how or why it happens. I'm guessing it's actually surface bubbles or debris being dragged by the direction of the waves.

Haven't seen it in at least a week and today the sky is blue and the sun is out! So despite getting some nice photos of footprints in the sand (the river banks are sand by Blackfriars Bridge and it's low tide right now) I just had to go with something blue and cheerful.

Fairly calm day but as I'm in central London for this photo there's a tiny bit of choppiness from boat traffic.

Looking down along the river wall the high tide was moving along the wall and between pillars of piers. I wanted to capture the way the water was moving two directions due to posts under the water surface, and the black 'hole' near the center is the start of a little whirlpool. The water is then moving away from that area in both directions, producing the two wave lines.

Yikes was it freezing out this morning! I decided to get straight out of bed and go do my photo this morning. A windy cold day, so there were nice flowing waves on the surface. Sunny and bright, but the colour actually changed immediately from blue to green grey as cloud blew over.
