Still rather busy, so here is a picture of a dog wearing glasses and a tie plus a few other dog photos (including a very squirrely hound dog that only a lunatic would try putting glasses and a tie on).
Some more quick tips for pets. Do some of the same things you would do for a toddler, just in different areas. For example, do a face check, especially around the eyes as dogs tend to have dried tears there. The bigger or furrier the dog, the more likely there will be dried tears there. A quick wet paper towel wipe can solve that. You can go a step further and deal with any dander in the fur. Either way, look for stuff like that because it can be a real challenge to edit out in processing.
Remember, just because photo processing software exists it still takes time to manually go in and do those edits. If you don’t have to do those edits in the first place, then you save that time to use for something else and avoid a botched photo process edit job.
Finally, and this is the broken record part of all pet related photography posts: pets just want to make you happy. Keep your cool and keep things happy, they don’t know what a camera is or what you are trying to do.
This was a 3-light setup. One light overhead on the ceiling aimed down with a snoot, the key light up front with an octagon softbox, and a light in back with a long softbox. Also, I had a reflector up front on the other side of the dog with the white side reflecting light.
