Weekly Photo Assignment: Sea Life

Each week we’ll be giving you a theme that you can submit a photo for, and we’ll choose our favourite to be featured on the Nature TTL website. Participating in these assignments will be a great way for you to force yourself to push the boundaries of your photography and improve together as a community on the website.

Week 115: Sea Life

Our theme this week is Sea Life. Your challenge is to find and photograph marine life that lives in or near the sea. This assignment is for terrestrial and underwater photographers, and we hope to see images taken from above and below the surface. We can’t wait to see what you can come up with!

Here are some tutorials to help you:

Last Week’s Favourite

Here is our favourite submission from last week’s theme, Urban Nature. You can view all of the entries here.

This week’s winner is from MeandMolly. For such unlikely subjects, this image really tells a story. It is as if the real plants have been fooled by the fake grass of the photographer’s doormat. The red of the Cranesbill is a nice contrast to the green of the mat, while it’s natural shape helps it stands out against the wall behind it. It takes a few moments to realise there is a second plant growing on the right, adding an extra surprise to the image. Well done!
