Take your photo with a digital camera, a phone camera might not be sharp enough to capture all the details.
If possible, take your photo outside in natural light, if this is not possible, take beside a window.
Get down close to the subject and eye level shots are usually the best. You may need to lie on the floor if your pet is very small, or lift them onto a table if it is safe to do so.
Remove any the pets collar or bridle if you do not wish this to be included. Dress/style the subject in the way you would like them to appear. Although I can use a bit of artistic licence … removing food from around a toddlers mouth or an ill-timed spot.
This photo is very cute but
not clear enough to work with,
it is low resolution and
