LProf is an open source application that creates ICC profile for cameras, scanners and monitors.

#### Resolution (CLUT points)

This set of radio buttons are used to select how many points will be included in the profiles Color Look Up Table (CLUT). Select smaller values to make small but less accurate profiles. Select larger values to create larger more accurate profiles. This can also be used to make Matrix/Shaper profiles by selecting the Matrix radio button. Matrix/Shaper profiles will be the smallest of all profile types.

#### Profile Verbosity

These radio button allow you to control how much additional information is stored in the profile. Selecting "Only required tags" will store only information that is absolutely needed in the profile. This makes for smaller profiles. "Store additional tags" stores additional information but does not store measurement information. "Verbose, store anything" will include everything that can be included in the profile including measurement information that is useful to the Profile Checker and other software such as iccexamin.

#### Chromatic adaption & viewing condition

This functionality has been completely revamped with the release of LProf version 1.11.5 and is now much more powerful. It is now possible to set both the "Assumed device viewing conditions" and the "Assumed PCS viewing conditions".

The "Assumed device viewing conditions"are the lighting that will be used where the display is located. For most situations this should be set to one of the sRGB values There are other pre-defined setting that are based on published standards that can be selected. In addition, users can set these to almost any arbitrary set of values. Settings other than one of the sRGB values are in general very specialized and should only be used by users who know specifically why they are making this change.

In most cases the "Assumed PCS viewing conditions" should be set to "ISO-364 P2 ICC reference medium". Like "Assumed viewing conditions for the captured medium" setting there are a number of industry standard presets available and users can select almost any set of arbitrary values. Settings other than "ISO-364 P2 ICC reference medium" are in general very specialized and should only be used by users who know specifically why they are making this change.
