The first Sunday of every month a tianguis or street market is held in Port Isabel, Texas.. The market is in a sub-tropical setting and features a very colorful ambience. I’m trying a practice my street photography skills in anticipation of a return to the Mayan highlands of Guatemala during the summer of 2020. Currently I’m using a Nikon D60: and D700 - are they doing the job or do I need something more modern for the upcoming trip?
