Can anyone recommend a good source for hi-res HDRi skies. Ideally free but I am willing to pay. I've had a look at the links to some of the HDIs on this forum but a lot of them are not that good low-res images. If anyone is using some commercial images that they would recommend then that would be brilliant as long as they are not too much money. I am only a hobbyist and don't have hundreds to spend on HDRis.
Cheers
