I usually ask the photographers which Magic shots they can do. All photographers can do Magic shots as far as i know.
That's the best way to find new ones is to ask them.
Depending on location they are different ones. Generally they only do magic shots during the day i believe.
I'll post the ones I can remember, and edit in if I remember more.
In March I got a bunch of new ones...
Jiminy Cricket in the front of Epcot & AK
In Epcot during F & G I got Butterflies.
In HS at
Pixar Place I got Mike Waz photobombing with his eye at the bottom, and Sully in another picture with me.
In the front of HS I got a Frozen icicle coming out of my hand.
The Stitch popping out of the ground you can get in all the parks I believe.
I've gotten Olaf in MK and HS
In MK in new fantasy land in the back I have gotten Lumiere. Also, Sebastion by Prince Eric's castle.
I've gotten Balloons in all the parks.
In Epcot I have gotten a Stitch eating an Ice Cream cone
