 where: -g    - set image gamma to specified value (default: $GAMMA)
        -cs   - perform contrast stretch operation
+	   -n	 - perform normalization on image
+	   -al	 - perform auto levels on image
        -r    - perform X-fold image size reduction, with binning*
-       -c    - create profile from input file
-       -u    - use created profile
+	   -t    - trim image by a factor of T (in most cases 1 is sufficient)
+       -c    - create frame profile from input file or files, then exit
+       -u    - use created frame profile
        -s    - separate given channel to make B&W image
+	   -o    - rotate image by O degrees (use negative value for counterclockwise)
        -m    - mirror image horizontally
+	   -ir	 - create an alpha channel from infrared channel (only HDRi files)
+	   -usm  - perfrom unsharp masking
