Hey everyone! Today we are launching our Best Photos of 2013 series. Just like last year, we’ll be sharing with you top photos in each category every day during the week. Before we start, let’s refresh our memories and revisit the Best of 2012 Roundup. Without further ado, please enjoy this year’s ten best photos in the Abstract category and come back tomorrow at 3PM EST for newly announced Best of 2013 images.
