Some helpful hints: if you have not yet taken pictures of your pet.

1. Send different pictures. Even if I will only use one photo for the portrait some of the others may contain useful details.
2. Make sure details are visible; natural light is best if it isn't too bright. Try to capture your pet's natural colors.
3. Pictures should be at your pets eye level, not from above. Have them look towards you (maybe someone behind the camera can attract their attention).
4. Your pet should fill the picture; it is extremely helpful if you have a close up of the face for details.
5. Do not take all the pictures at one sitting; have plenty of patience (try to make it fun for your pet with treats and toys). Sometimes it takes a while to find that "typical" pose to remember your pet by.
