As you can imagine, we receive images from a wide variety of sources, from digital cameras made for 'home use' to high-end cameras used in professional studios.
One of the most important things we do at MOO is print your photos to the highest possible standard. Photo Enhancement is an optional process, but it's auto-applied if we detect a JPEG photo. It adjusts a range of parameters, making each photo look as good as it possibly can before it reaches the printing press.
To add or remove enhancement from your photo, simply click on the image in the design workflow and tick/un-tick the photo enhancement option.
