If you are in the Creating Stage, this exercise is perfect for you!
Practise, practise, practise until you start becoming more sensitive to the White Balance and subtle changes. The only way this will get easier is to practise!
If you are in the Exploring Stage, try with some more challenging photos: forests, dawn/dusk, golden hour, even photos of other dogs. I’m sure people on Inspawration Connect would be happy to volunteer some photos!
If you are in the Beyond stage, try an extreme edit: turn day into night or dusk/dawn, or an overcast day into a golden hour photo. What colour with the light be and how would it affect the fur colour?
