Photoshop can be used to edit pictures by adjusting levels, brightness/contrast, layers, and saturation. Levels allow recalibrating the light balance to make images lighter or darker. Adjustment layers let you modify settings non-destructively by turning them on or off. Changing saturation alters the color intensity, while over-saturation can cause graininess.

• Levels recalculates the light balance in the image, by moving scale downwards, therefore
effecting the image and making it either lighter or darker.

4. Changing the Brightness/Contrast
• By changing the image brightness, the image will either lighten or darken up
• By changing the image contrast, the image will lose its colour quality whilst also becoming
eerie and washed out.

5. Adjusting layers
• Open Adjustment Layers, got into levels and adjust settings therefore effecting the image.
• Photoshop will then add an adjustment layer on the right hand side of the screen, click on
the eye to turn settings on and off

6. Changing the Saturation
• Changing the Saturation makes the image lighter or darker. When an image is over-saturated,
they tend to come out grainy.
