Here are 4 pictures for the abstract category. The first is a group of tiny fish in a murky pond. I played with the colors a bit…not one of my usual photos, but I thought it was interesting.
Second photo is a blue heron. The pine branches distracted from the heron, but they do make an abstract background.
Here’s one of Tybee’s famous sunsets…the colors make it seem like an abstract painting.
And last, here is a group of oyster shells. I thought they made a cool abstract shape.

Fish, sunset and shells are my favourites. Really like them.
Thank you so much….I have been hoarding the fish for a while….finally found a challenge that fit. : )
All pretty. I, too, have been saving a photo for some time and use it today. Don’t you love when that happens? 🙂

Thank you…yes, I do…especially for photos that I like, but are just a little out there.
