Ok this is going to be long but i will be able to help, but first off i would like to say it is possible to get all the figurines on the first quest. there are 134 is you want them all, but use this to help with the minor figurines.

Legendary Photos :
Fado , Laruto , King of Hyrule , Fairy Queen , Ganondorf And the Great fairy figurines can be purchased from lenzo at night depending on the moon, here is a great guide to help you with the moon cycles Another note is they are only available after you met them before.
For example, Ganondorf can be bought from Lenzo during the full moon after you are done with the 2nd trip through the Forsaken Fortress.
The bosses are a bit hard but most of them you get 2 chance to get them. So here are the boses:
Gohma: can be found in Ganon's tower or during the 2nd playthrough
Kalle Demos: Can be the same
Gohdan: Can be taken before the battle, during and after the battle. you just take a picture of his head on the wall and you got it.
Phantom Ganon: Can be attained during the 2nd time at the forsken fortress or ganon's tower. I would suggest taking multiple pictures, leave and get the figurine then come back for Helmorok King.
Helmorok King: You only get one chance so make it worth while and take 3 pictures.
Jalhalla: Can be found in the earth temple or Ganon's Tower.
Mogera: Can be found at the Wind temple or Ganon's Tower.
Puppet Ganon: You only get one chance per quest and make sure you get multiple shots, it doesn't matter which form you get.
OK this is is important if you want to get them all on the first go:
Kogoli: he is located on the launch platform on dragon roost (near Mail exit) He disappears after you learn the Earth God lyric
Cyclos and Zephos: Get Cyclos only to get both, All you have to do is get him before you attempt to get the "Ballad of gales" song.
Tetra: you get her after Forsaken Fortress 2nd time when she is following you hurry up ahead and get a picture of her.
Red Wizrobe: mini boss in wind temple, you only get one shot so don't blow it. the room where you get the hookshot is where it is at.
Now im going to tell you about bundles; some characters come bundled with figurines. here is a list of them:
Tetra: When you get her you get her pirate crew
King of Hyrule: bundles with Princess zelda when you purchase it from Lenzo.
Grandma: Aryll comes with her
Rito Cheiftan: Quill the postman comes with him
That's all i can think of for now concerning that.
Now there are some tough ones and here they are:
Fishman: he can be found anywhere but he is hard to get.
Valoo: it can be difficult but here is what you do. sail a bit away from dragon roost island and take a picture when you can see Valoo clearly.
Tingle quest figurine:
when you have a GBA connected and the tingle tuner you can talk with tingle on it well anyway collect the 5 tingle statues. and if you don't know i can explain it to you during the next PM
anyway after you get the 5 tingle statues, go to outset island and follow the hints that knuckle gives you. Knuckle will tell you these hints when you are at the beach.
After you are done with his quest he will be waiting at tingle island near the statues, take a picture and there you go.
Once you have collected all 134 figurines your reward will be:
Link and King of Red Lions figurines
If you need anymore help just let me know, im actually thinking about asking the staff if i can work on a figurine guide for Wind Waker.
