“Dodging and burning are steps to take care of mistakes God made in establishing tonal relationships.”
– Ansel Adams
Dodging and burning is actually not a Photoshop discovery – those who have a history with film will know that these are darkroom techniques replicated for the computer. Simply put, the dodge tool will lighten your tones (increase exposure) and the burn tool will darken your tones (decrease exposure). In the film darkroom, you would hold an object (usually a piece of black foam board on a dowel) to block parts of the negative from hitting your photo paper during exposure.
With the help of Photoshop, you can execute these techniques a little bit easier. Dodging and burning works especially well for black and white photography since you’re just dealing with tones, which is what I'll use for my example image (below).

1. Open your image in Photoshop after any RAW editing. It would be ideal to convert to black and white in RAW first if you plan to only process this as a b/w – this will ensure that you have the highest quality image.
2. Duplicate the layer so that you will always have your original to revert back to if necessary (I recommend this for ANY photo editing).
To add more drama (especially to black and white photos), I like to go over my images with a very light highlight dodge (to bring up my whites) and a shadows burn (to deepen my darks), which is what I'll explain in this tutorial. This gives me more contrast to a gray and boring image, but with the added control of a brush tool – meaning that I can selectively choose what areas I want to change, and how strong I want those changes to be.
3. Select your Dodge tool and you’ll notice that you have three options to choose from in the Range menu – highlights, midtones, and shadows. These selections are literal – you can choose to dodge (lighten) your shadows (tones towards the left of your histogram), midtones (tones in the middle) or the highlights (tones gathered on the right). For this image, I want to add a lot more contrast and tonal range so I’m going to select to brighten my highlights (Figure 1).
4. With a brush size suitable to the area you want to affect (you can change this instantly by pressing your “[” and “]” keys), start with an Exposure level of about 10% and brush around your area. You can increase or decrease the exposure as necessary. For this image, I want to add a little more tonal range in the middle to brighten up my highlights (Figure 2).
5. When you’re finished working with your dodging, you can then move onto burning. I prefer to dodge before burning since if I want to lighten any highlights in my image, I don’t want them getting darker first with the burn tool.
Select your burn tool and, like we did with the dodge tool, choose the tonal range you want to darken. Since my goal is to increase drama and contrast, I’m going to burn my shadows as the original image is flat with little to no dark tones.
With an opacity level at 10% to start, brush over the tones you wish to darken (Figure 3).
When we compare the before and after, you can see a notable difference in both the atmosphere and the tonal range – going from a flat, uninteresting image to a dramatic coastal scene.
Important notes: Since I’ve increased the tonal range, I’ve also made my noise stand out a bit in the sky. I could remove it using several techniques, but I like the grainy effect as it compliments the moody atmosphere. Also, there is a bit of banding in my new image from the intense dodging and burning. Typically, you won't go to the extreme level as I did, but to reduce this effect I would edit my photo at a 16bit image instead of 8bit – you can change this in your RAW editor before importing to Photoshop. This will give you a better tonal range and more information to work with; this is especially important for black and white images as you're strictly dealing with tones.
Dodging and burning is not just a technique to use, it’s a way for you to direct the attention and focus of your image. If there are distracting elements around your subject, you can simply burn them to minimize their presence. Alternatively, if you want more attention on your subject, you can dodge the area around the general vicinity to make it more apparent. Since you’re working with your brush tool, your options are endless.
One final tip: try to avoid burning the midtones too much as it will give an overall gray appearance to your tones. The same goes for dodging – it will make your image look cloudy and uninteresting. Instead, do some midtone work but also try out the highlight and shadow options to work the different tonal ranges.
