Some galleries will offer photographs with the Low-resolution Digital Copy as an option for purchasing. This option will allow you to download a 1024px sized image (on the longest edge) for your personal use, such as on social media.
The Low-resolution Digital Copy option does not allow you to commercially publish or use this work on sold items. To use photos in this way, please purchase the Digital Copy (Commercial Use) product to gain rights to use the photograph, along with the photograph at its original resolution.
If you simply want a copy of the photograph at the original resolution but do not require a commercial lisence, you can purchase the Digital Copy (Personal Use) product. This follows the same terms as the Low-resolution Digital Copy product.
