Difference between CV and CVF curves:
CV curves are the standard RGB curves.
CVF curves are special versions of the curves which intends to avoid color shift side effect of
the RGB curves. They are an approximation of the luminance curves.
Except the SYSCURVES.CVF file it is recommended to put the curves files in the
CHDK /CURVES directory.
See:-
Enable Curve
[ None, Custom, +1EV, +2Ev, Auto DR]
• None -
No curve profile is applied.
• Custom -
A custom curve profile is applied as-is.
The following three options require that you have a SYSCURVES.CVF file in your /CHDK folder,
this file is included in the "complete" CHDK packages. It is also contained in a file at -
which also
contains the editor.
Due to the limitation to short 8.3 file names in the file browser of current DryOS-based cameras the
file "SYSCURVES.CVF" should be placed on the memory card by a card reader, in the CHDK File
Browser the file name is shown in shortened format as "SYSCUR~1.CVF".
