Pick a spot in the painting or photograph where you think
you won’t be noticed and then walk directly toward it.
DO NOT take your eyes off it or you can get lost
between worlds! Foregrounds, backgrounds and
shadows are good places to melt into the image,
but if you’re feeling frisky, you can walk
right up to folks and talk to them.
 

You should also keep appropriate clothing handy.
Like when I’m going into the antique middle east,
I wear this Shriner’s fez. It makes me look important,
don’t you think?
 

Anyway, that’s how you do it.
Glad I was able to help.
