I have been having difficulty finding backgrounds that fit with my horses in way that I like. I am also just struggling finding nice backgrounds. If anyone has suggestions on how they choose backgrounds that is greatly appreciated.

I get almost all of my backgrounds from Unsplash. They have some really great, unique, and high quality photographs.

Yes, Unsplash has the best backgrounds.

I have been looking at unsplash and shutterstock but I canÂ’t find any with the angle or lighting that I like. It might just be my brain that is struggling

When all else fails.... make your own. :D

True, I have to try that

Fallen cherubim has beautiful stock ^-^

Honestly? I just use a random Deviantart stock background and edit the heck out of it until it's basically unrecognizable. If the stock is in a suitable background, I will take a shortcut and simply edit the fences out of it if any (The "J" key is my lifeline!) and make it look completely new and original from the stock image I started with. For blurring I will use lens blur on the horizon, the quick select tool on Photoshop is very good for that. A great lighting effect can be found with Picmonkey's effects "Sunglow" and "Radiance." I always use Picmonkey for finishing lighting.
