There's a basket full of tools available to use in Photoshop that can help you bring photos back to life. Below we outline a few very useful ones and we apply them to this original image:
Adjusting levels of your image is all about changing the amount of light your image displays across different frequencies. You cab make levels changes by going to the Image menu and selecting Adjustments followed by Levels. The screenshot below indicates the input levels of your image.
