By using the following adjustment options, I was able to edit my front cover photo to have the desired effect.
- Brightness and Contrast can allow a photo to change from appearing to be taken in the day, to appear to be taken at night. It can either brighten or darken the overall tones on the image and by using the contrast scale, the sharpness of the photo can be manipulated to appear either more crisp or blurred.
- Shadows and highlights allow you to change the visual dimensions of the face and provide the opportunity to make an image appear more three dimensional due to creating shape. This is done by playing with shadow levels and highlighting where appropriate, to manipulate the surrounding lighting.
- Exposure allows you to either increase or decrease the highlights of an image however maintaing the dark shadows. Offset and gamma are slightly different, offset adjusts the midtones and gamma adjusts the dark tones.
- Hue changes the colour of the image by altering all tones to one specific colour with light and dark. Saturation, when decreased, can remove all colour from the image making it appear in black and white. When increased, can exaggerate all colours making them appear almost aluminous. Lightness can remove either all of the light tones, or all of the dark tones out of the image.
