HDRI photos

So I’ve been going around the webs trying to find cheap spherical HDR photos to use for my architectural renders, but damn they’re expensive. Any ideas on how these photos are made? Types of cameras, stitching and converting software?

I have no idea if any of you even use HDR files, just putting it out there.

uhm, there are tons of free HDRI images in the web, why haven’t you found one yet?

Anyways, I’ve seen several tutorials where they explain how to use a chrome ball to take those shots.
you need a good camera, which stores the photos as a raw file.
