Hello my online user name is Kippa, my real name is Michael. I'd just like to state for the record that all photography on this Deviant Art account constitutes as free stock photography. They can be used for whatever purpose be it personal or commercial. You can change and alter the photographs without restrictions. You don't need permission to use or change my photographs. What I do ask is if you do use my photographs could you please credit me, it is NOT required it would just be nice.
5K photographs vs 4K photographs
Some 5K photographs have 4K versions of them, but not all of them. The 4K versions are both resized and cropped to exactly fit 4K TVs and Monitors being 3840x2160. When cropping you loose some of the top and bottom of the 5K versions due to the 4K photographs having a different aspect ratio (1.78:1) compared to the 5K ones (3:2) . So if there are 2 versions and if you have a 4K monitor then I'd recommend you go for the 4K version, or if you are after a larger version that isn't resized and cropped then go for the 5K version.
