Lesson 8 - Fixing under- or over-exposed photographs using the Levels dialog box.

At the end of this lesson, you will be able to demonstrate how to correct an over- or under-exposed photograph by adjusting the tonal range of the image using a command called 'Levels' in Photoshop CS3. The 'Levels' command has control over the highlights, midtones and shadows of an image. Adjusting the 'Levels' by dragging the input slider under the histogram to the edge of the first group of pixels on either end of the histogram will achieve this.

Requirements:

• Watch the video tutorial shown on the next page.
• Open 'OriginalImage1.jpg' and use it to practise the method shown.
  Note: OriginalImage1.jpg can be downloaded in 'Photography Preparation - Lesson 1'.
• Save your file when all adjustments have been made but give it a new name so that 'OriginalImage1.jpg' can be used for all subsequent lessons. Select 'File > Save As' and call it 'Lesson 8.jpg'.
