It's in the Disney app, but this info I found on fb from Perlster Pix helps a bit even though the info is related to Photopass.
*First, if you are fan of any of the following characters, some bad news:
My experience is that - even though they are commonly seen -
you will have no chance of getting Photopass shots with:
Alice, Mad Hatter, Peter Pan, Bert, Mary Poppins, Captain Hook,
Fairy Godmother, and [Snow / Evil] Queen Grimhilde.
*At the park entrance, it's very common to see a photographer taking
pictures of guests in front of the floral Mickey. However, when princesses
are in the area - usually to the right of the floral Mickey - I have never seen a photographer with them
*Taking into account the exceptions above, when a character is holding
a meet 'n greet session in Town Square, a photographer is generally present.
*At Fantasy Faire, Merida and Rapunzel greet guests outside.
A photographer should be there, but occasionally has showed up
late or been absent from an early meet 'n greet session.
*Inside the Royal Hall at Fantasy Faire, a photographer is present
with each princess you meet.
*One or more photographers are often taking pictures of guests in the
forecourt of Sleeping Beauty's Castle.
*Photographers are always present in Pixie Hollow.
*Captain America and Thor have a temporary meet 'n greet
location across from Innoventions, against the building with the satellite
gear on top. You can expect photographers to be there.
*I haven't seen this myself, but a photographer supposed to be at each Jedi Training Academy session in Tomorrowland.
*From what I've seen, there are very few photographers in
Disneyland Park that aren't always assigned to a fixed location (generally with characters).
Here are some exceptions I've noted: A photographer is occasionally
just inside Fantasy Faire - on the path nearest the castle. The other
places you may find such an unattached photographer are at the wishing
well or further down the right side path around the castle.
*However, when a character (usually Aurora now) is at Snow White's
wishing well, no photographer will be present.
*No photographer will be taking pictures when a character is meeting
guests in front of the Dumbo organ.
*When characters are seen in front of back drops at Big Thunder Ranch
Jamboree, a photographer should be present at each location. If characters are roaming about the area, no photographers will accompany them. [It now looks like BTRJ will be closed permanently soon and these appearances are in the past.]
*Expect to find a Photopass photographer when Jack Skellington and Sally
appear in New Orleans Square during Halloween Time.
*Also during Halloween Time, one or two photographers are often stationed at the pumpkin Mickey in Town Square.
I am less certain of the likelihood of a photographer being present
at the final three locations:
*Woody and Jesse can be seen during meet 'n greet sessions at Big
Thunder Ranch, just outside - and to the left of - the Jamboree entrance.
This will be a "maybe" until I have more chances to see the two
characters here (or if other visitors can add their observations)
*Aladdin, Jasmine, and/or Genie used to meet inside Aladdin's Oasis,
but now greet guests just outside, to the left of the entrance.
Before, this would have been a definite "no", but it seems now that a
photographer is often (if not always) present.
*Tiana meets in New Orleans Square - the usual location is on a sort of
elevated platform near the French Market, toward the Rivers of America.
I'm considering this to be a "probable" location to find photographers.
[She may not appear during Halloween Time since Jack Skellington and Sally meet guests in the same place.]
Reports of your own experiences with Photopass photographers in
Disneyland Park are welcome in the comments. This post will be updated
as my own future observations and other new information allow.
