 **AdjustContrast** changes the contrast of the image using the percentage parameter and returns the adjusted image. The percentage must be in range (-100, 100).
 The percentage = 0 gives the original image. The percentage = -100 gives solid grey image.

 **AdjustSigmoid** changes the contrast of the image using a sigmoidal function and returns the adjusted image.
-It's a non-linear contrast change useful for photo adjustments as it preserves highlights and shadows details.
+It's a non-linear contrast change useful for photo adjustments as it preserves highlight and shadow detail.
 The midpoint parameter is the midpoint of contrast that must be between 0 and 1, typically 0.5.
 The factor parameter indicates how much to increase or decrease the contrast, typically in range (-10, 10).
 If the factor parameter is positive the image contrast is increased otherwise the contrast is decreased.
