You may get some amazing locations in Dallas downtown. I would recommend you choose weekend for shooting in Downtown.
AT&T Discovery District
This is again part of Dallas Downtown and this place is crowded mostly but it's best place to shoot during off hours.
Recently I went to this place and I must say it's awesome and really great for photography. So many attractive locations at one place.
This is the place you want to be if you like shooting between the nature. It's full of beautiful natural locations.
My personal favorite because I used to live very close to this location and I don't know how many shoots I did here.
Very popular location in Mckinney area and you will see lot of photographers here. Adriatica Village is a beautiful European-style village located in McKinney
Pretty small location but you may find some really amazing places with colorful design walls.
I always like sharing the photoshoot locations because I get messages in my inbox and it's helpful for others.
