Does anyone know someone who analyzes apparitions in pictures

My friend took a picture during graduation & it seem like a little demon is in the background. She took a picture before & after in the same spot and the demon thing is gone. Is there anyone that can look at this picture and help decipher what it could possibly be??

Of course I would love to take a look at such a picture. I have an experience in telling if it was some kind of error in the camera or if it was really a demon.
And also I will be really excited to see a demon.
