Sometimes a single, "static" default processing profile is not enough to cover
all use cases. For example, the amount of noise reduction to apply varies
according to the Camera and ISO setting used. Another example is the kind and
amount of lens corrections needed, which is obviously dependent on the lens
used.

In order to handle such cases, RawTherapee provides a feature that allows to
create a default processing profile "dynamically", based on the metadata of
the image being processed (such as camera and lens name, shutter speed, ISO
value, and so on).

This is done by defining a set of "Dynamic profile rules". Each rule has a
[[Creating_processing_profiles_for_general_use|(partial) processing profile]] attached to it, plus some conditions on the image
metadata that define whether the rule is applicable. When a picture is edited for the
first time, the list of rules is scanned, and all the profiles that match are
combined (in the order given, so later rules can override earlier ones) to
build the initial processing profile.

In order to activate the functionality, the [[Preferences#Default_Processing_Profile|default processing profile]] must be set to "(Dynamic)".
Rules are defined in the [[Preferences#Dynamic_Profile_Rules_Tab|Dynamic Profile Rules]] section of the preferences window.

Dynamic profile rules work on the following image metadata:

; Camera
: the camera name (including brand) as shown in the image info overlay of the [[The_Image_Editor_Tab|Image Editor]]. If active, by default this entry will cause the rule to apply only to pictures taken with the exact camera specified here (except that the capitalization of the string is ignored). However, if the entry starts with the <code>re:</code> prefix, then the rest of the string will be interpreted as a [https://en.wikipedia.org/wiki/Regular_expression regular expression] to use for the matching. For example, a rule with the Camera value set to <code>re:SONY ILCE-[56].00</code> will be applied to all Sony Alpha a5xxx and a6xxx cameras.

; Lens
: the full lens name. As above, a regular expression can be used by starting with the <code>re:</code> prefix

; ISO
: the range of ISO values

; Aperture
: the range of apertures of the lens (measured in f/ stops)

; Focal length
: the range of focal lengths used (in mm)

; Shutter
: the range of shutter speeds in seconds (for example, enter 0.03 for a speed of 1/30")

; Exposure compensation
: the range of exposure compensations.
