Hi,
numerous agencies - FT and BS come to mind first - ask you to specify whether files you upload are 'photos' or 'illustrations'. For those of you who upload 3d renders, what do you choose? It seems that they accept images no matter what is selected, though. But then again, buyers can filter 'photos' or 'illustrations' out... What option do you prefer?
Thanks
If it's not a photo then it's not a photo - as simple as that.
If a buyer wants a photo realistic 3D image it should be found in the illustration/3D category IMO.
