A photo background doesn't have to be "busy" with a lot of detail to compete with the foreground. It can be simple like some distant mountains (or buildings) like in this picture. I misted the photos with dul-cote to give them a hazy off in the distance look.
Mike,Unlike rolling hills it's harder to blend in a industrial scene where everything looks like it belongs.You just need to use industry photos that looks like they belong with the modeled industries.
Excellent job by the way.
Thanks for the replies guys.
You all have made some really good valid points.
Gives me a lot to think about
BTW-nice job Mike.
