I just came across this little gem, beautiful composition and color, I bet they didn't use a dslr to shoot this :)

The guy who directed this also has a impressive portfolio: COMMERCIALS ? Macgregor (http://macgregor.works/commercials/)

Shot with a Sony F35. A big and heavy beast for traveling and shooting atop railroad cars, but the results speak for themselves.

That was awesome. Thanks.
