LECTURE

Adjustment Layer

Non-destructive image editing tools that add colour and tonal adjustments to your image without permanently altering the pixels. You can edit and discard your adjustments anytime. When you add an adjustment, a new layer will pop up where you can adjust it accordingly.

1. Brightness/Contrast

Makes adjustments to the tonal range of your image. The brightness slider controls the highlights and the contrast slider controls the shadows.

2. Level

Makes adjustments to the levels of the shadows, mid-tones and highlights. 

3. Curves

Lets you adjust as many points throughout the tonal range as you want in the image and is one of the most powerful and precise tools in Photoshop.

4. Exposure

Lets you adjust the exposure using three sliders: Exposure, Offset and Gamma. Exposure adjusts the highlights, Offset adjusts the mid-tones and Gamma adjusts the dark tones.

5. Selective Colour

Selectively modifies the amount of primary colour without modifying the other primary colours.

Filters

There are a variety of filters in Photoshop that adjust the colour, blur, sharpness etc. of your image.
