1 GATHERING References
To achieve a photorealistic result it is crucial to find good references. I recommend using Google images and flickr to find high resolution images; this way you’ll be able to see and breakdown all the details in your textures. After picking a good amount of references I use a software called Pureref to categorise them. I separate the references based on the casque, beak and skin. Since each bird is so unique, it is a challenge to find a middle point between the photos.
