Photoshop Editing Process - Levels

Evaluation:
Whilst I prefer the top image before using levels this technique is very important and I will be using it again in the future. This is good for adjusting the contrast and the brightness in a more professional way than the original 'Contrast and Brightness' tool.

Process: Levels

Begin with the original image. 

Select the 'Levels' tool.

Finally, move around the arrows to adjust the contrast of the image. This is the final outcome.
