In most adventures* which normally have a large field of view (FOV), the FOV is smaller than usual when you first play those adventures immediately after logging on. If you have played any adventure prior to this however (not including the training grounds), the FOV will not be smaller.
*Exceptions Include
The Forgotten Desert
If you go into an adventure afterwards however, you can do a glitch to make your FOV smaller, without having to reload.
This glitch doesn't work with:
The Training Grounds
Return of The Phantoms
The Phantom Portal
Meet Cosmo
The Hive
The Great Escape
Bubble Trouble
In Too Deep
Turning The Tide.
This glitch works with:
Tiki Trouble
The Forgotten Desert
Greely's Inferno
The Search for Greely
The Hidden Falls
The Front Lines (Both opening & main quest)
The Phantom Badlands
The Phantom Fortress
Storming the Fortress
The Trials of Zios
The Mystery Below
The River's Heart.
Example in Tiki Trouble:
Small FOV Large FOV
Step 1: Minimise the Animal Jam window once you are inside an adventure OR start the adventure with a minimised window.
