Will your space that you developed, like this one, need to have AC or heat? That is entirely up to you. Let me explain.
When I rented this space, we used our studio for testing and beta testing a ton of cameras and ideas. I’m in Florida, and I don’t know if you can tell, but I’m a little “dewy.” We don’t spend eight or nine hours per day in here shooting, and we have some fans around, so I chose not to do an AC.
I’ve personally been in spaces in Canada and New Jersey, and one experience was eight degrees. I walked into the studio, and the photographers were in a mask and gloves. It was eight degrees.
What happened to the studio? Absolutely nothing. The plastic, though, when we put the seams together, because of the cold air, shrinks, and it creates a little seam. You can’t see if the photos are shot properly. That’s the only thing that happens.
So, to answer your question, do you need AC or heat? That is entirely up to you.
I’ll ask you another question. If I had you shooting the cars, and you had to spend six hours in a freezing building, how long would you stay?
