Preferences of the add-on can be found in Edit > Preferences > Add-ons > Camera: Photographer
Navigate through the different options using the Tabs at the top.
From 5.2.0, Preferences are stored if you disable the add-on or install a new version. You will find the saved preferences as a .json file in the presets folder.
On Windows, by default: %appdata%\Blender Foundation\Blender\*version_number*\scripts\presets\photographer\
If you are not using the latest version of the add-on, a warning message will appear at the top of the Preferences, with links to quickly access the market where you bought the add-on.
A changelog of each version you have missed will be visible, to inform you about the content of these updates.
You can also find the entire changelog from this mockup github repository:

Panel Category and LightMixer Panel Category:
You can change the category name, which is the name of the tab available in the 3D view add-on panel.
Tip: You can type the name of existing categories to merge Photographer panels into an existing tab.
Add-on Panel Visibility:
In case you are not using all the functionalities of Photographer, you can decide to hide some of the panels by toggling off their visibility settings.
Screen Resolution:
Setting your current monitor resolution will help the add-on calculate when to display more settings, if the add-on panel has been scaled wide enough.
Show Compact UI:
Adds quick access properties to the Panel to be able to tweak most important settings without opening advanced options.
Left: Show Compact UI On // Right: Show Compact UI Off
Show Autofocus buttons and Show 'Lock Camera to View' in 3D View Header:
Show / Hide the buttons at the top (or bottom) of the 3D view.
Show Master Camera Feature:
Hides the Drone Camera button at the top of the Camera List.
Photographer has a Sticky Menu that is a copy of the entire Photographer panel.
By default, this menu is accessible with the Ctrl + Shift + Alt + C hotkey. You can change this hotkey in the preferences.
Photographer has a Pie Menu that allows you to access the most important settings directly in the 3D View.
By default, this menu is accessible with the Ctrl + Shift + C hotkey. You can change this hotkey in the preferences.
World HDRI: Path where you want to store your 360 HDRIs to be used in the Light Mixer World settings.
You can organize your HDRI library using subfolders (only 1 level of subfolder is supported).
Supported formats: .HDR, .EXR
Thumbnails will be automatically generated for HDR and EXR files that are smaller than 100MB. PNG files with the same name as the HDR/EXR files can be used as thumbnails for large files or to speed up the menu opening.
Optical Vignetting folder: Path where you want to store textures for Optical Vignetting.
Supported formats: .JPG, .JPEG, .PNG, .TGA, .TIF, .TIFF
Default folder: scripts/presets/photographer/optical_vignetting
Photographer comes with a few textures and will install them in the default folder.
Bokeh folder: Path where you want to store textures for Bokeh.
Supported formats: .JPG, .JPEG, .PNG, .TGA, .TIF, .TIFF, .HDR, .EXR
Default folder: scripts/presets/photographer/bokeh
Light Gobo folder: Path where you want to store textures for Light Gobos.
Supported formats: .JPG, .JPEG, .PNG, .TGA, .TIF, .TIFF, .HDR, .EXR
Default folder: scripts/presets/photographer/light_gobos
IES Profiles folder: Path where you want to store textures for IES profiles.
Supported formats : .IES
Default folder: scripts/presets/photographer/ies_profiles
STMaps folder: Path where you want to store textures for STMaps.
Supported formats : .IES
Default folder: scripts/presets/photographer/stmaps
Film Grain folder: Path where you want to store textures for Film Grain.
Supported formats : .JPG, .JPEG, .PNG, .TGA, .TIF, .TIFF
Default folder: scripts/presets/photographer/film_grain
Photographer comes with a few textures and will install them in the default folder.
Focus Eyedropper: Choose your preferred operator when using the Focus picker from the Photographer panel.
Full Viewport Framing: creates a new camera with a field of view matching your current viewport framing.
Camera preferences allow you to set some default settings for new cameras.
Important: These settings only work for cameras created using the 'Add Camera' button in the Photographer panel, or with the Photographer Camera in the Add Menu.
Exposure preferences allow you to set some default settings for cameras, so you don't have to set them every time you create a new camera.
Important: These settings only work for cameras created using the 'Add Camera' button in the Photographer panel, or with the Photographer Camera in the Add Menu.
Reset Exposure when not overriden: Enabled by default.
If using a Main Camera, the camera that does not override Exposure will inherit its values from the Main Camera.
If there are no Main Camera set in the Scene, disabling the Exposure override will reset Exposure to 0.
If Reset Exposure is disabled, the Cameras with no Exposure override will do nothing and will inherit the last set Exposure.
If you do not wish to use Photographer Exposure at all, disable Reset Exposure in the properties and make sure to not enable Exposure override on any camera in the scene. This will give you the possibility to set the Blender Color Management Exposure setting manually without being affect by Photographer.
Lens Attenuation factor: Factor depending on the transmittance of the lens, the vignetting factor, and the angle relative to the axis of the lens to define how much light energy passes through the lens.
The default value of 0.78 will cancel lens attenuation calculations and will match Unreal 4.25 camera exposure.
ISO standard recommends a lens transmittance of 0.65, which is sometimes used by other render engines to match real cameras.
Match Blender ACES to Unreal ACES: If using ACES OCIO config in Blender, you will notice a difference of brightness between Blender and Unreal ACES. Epic apparently applied a 1.45 gain multiplier their ACES ODT.
Enable this setting to apply the same multiplier to Photographer's Exposure. It will only affect Exposure if using the ACES OCIO config.
Use Physical Lights: replaces Blender Light properties with Physical Light properties, adding Color Temperature and Physical Light Units.
Follow Scene Unit Scale: Properly multiplies Physical light intensities with the Scene unit scale.
Only disable to keep retro-compatibility with older scenes.
Keep showing Blender Light panels: Does not hide Blender's light panels when using Physical Lights.
Can be useful if Blender adds new light properties that Photographer hasn't added yet.
Light preferences allow you to set some default settings for lights, so you don't have to set them every time you create a new camera.
Important: These settings only work for cameras created using the 'Add Light' buttons in the LightMixer panel, or Physical Light buttons in the Add menu.
Light Sampling Threshold: this Cycles optimization stops light sampling of lights that give very little contribution to the scene, below this threshold.
Unfortunately, the threshold doesn't follow the Scene Exposure and can create a lot of noise in low light situations.
Photographer will warn you if the current Light Sampling Threshold is too low for your scene Exposure and suggest you to Calculate a new value.
You can decide to Hide this warning, or to update the threshold automatically when changing Exposure.
Note: It is not recommend to check Auto Update as it will force a Viewport refresh when changing Exposure.
