I used the 12x18 size. Large enough .. there is one by Kookie on the wall.
It is not a size you can have done the same day. I had mine done at Walmart and I was able to walk in and pick up that size frame (in stock)
Pics with frames cost me about $16 together the last time.
Of course I have spent lots of trips and hours to capture and select ones that I would use. Other than the pics I dabbled with photoshop to make them unique.
If I have taken your pic I might be able to find it. If you want to use mine, okey dokey 😋
Ansel Adams n Norman Rockwell later.
The thought that pops up is Rockwell in front of a canvas painting pics of animals and people.
There are such 'artist' who have their subjects pose for a looooong time (trying not to move)
But Norman Rockwell used a camera, had a dark room and assistants to create his works.
