Reintroducing the HDRi bundle pack from MasteringCGI. Now at discounted prices, several resolutions to chose from and as a bonus, free 1k versions of all HDR images.
The different options are:
10000 x 5000 px at $200 ($2.50 per HDRi)
8192 x 4096 px at $160 ($2.00 per HDRi)
4096 x 2048 px at $80 ($1.00 per HDRi)
The 1k HDRis come with unobtrusive watermarks and reduced dynamic range. They're only samples, but will still work nicely for look dev. Consider buying one of the higher resolution packs to get higher dynamic range and no watermarks.
