11.  Invert the mask

Press Ctrl+I to Invert the Levels Adjustment Layer's mask so that the girl's shape is white, while the background is black. These white strokes will enable the Levels Adjustment Layer to change the tones of the girl without altering the carefully dodged and burned tones in the rest of the image.

12.  Adjust the levels

Click on the Levels Adjustment Layer's thumbnail (the little cog icon) to see the Image layer. In the Levels adjustment panel drag the grey slider left to 1.24 to lighten the girl's midtones.

13.  Restore clipped highlights

The highlight Levels adjustment brightens up our subject and gives her more impact, but her white shirt has become clipped. To restore detail to the shirt's blown-out highlights, grab the Brush tool from the Layers palette. Set Opacity to 50%. Now click on the mask and spray grey strokes on the shirt.

14.  More modeling

To emphasise the contours of the girl's face, increase the contrast between the shadows and highlights. Grab the Burn tool and set Range to Midtones and Exposure to 15%. Set Size to 90 pixels. Click on the grey Dodge and Burn layer. Spray over the shadows on her neck and cheek to darken them.

15.  Reduce saturation

The model’s colours are a little too vibrant. To create a more subtle colour palette choose Layer>New Adjustment Layer>Hue/Saturation. Drag this Adjustment Layer to the top of the layer stack. In the adjustment panel, drag the Master Saturation slider down to -21. This creates a moodier look.

16.  Go grey

To 'rough up' the clean digital image and give I O the whole thing a more filmic look, choose Layer>New>Layer. In the New Layer window, name the layer 'Grain' and click OK. Next, go to Edit>Fill Layer. In the Fill layer window set the Contents Use drop-down menu to 50% Grey. Click OK.

17.  Make some noise

Set the Grain layer's Blending Mode to Overlay I / so that the neutral grey pixels become invisible. Go to Filter>Noise>Add Noise. Set Amount to 10%. Tick the Monochromatic box. Click OK to apply the noise to the layer. At this stage the noise doesn't look like film grain, but we'll fix that in the final step.

18.  Create film grain

Go to Filter>Blur>Gaussian Blur. Set the Blur Radius to 1.0 and click OK. This turns the sharp dots of noise into more organic-looking clumps of grain. To see the grain more effectively, grab the Zoom tool and click to view at 100%. For a more subtle effect, reduce the Grain layer's Opacity to 70%.

Overlay

The Overlay Blending Mode makes pixels that have a 50% grey value become transparent. By using the Burn tool to make the grey pixels become darker, you can darken pixels on the layers below. This enables you to burn a picture's pixels in a non­destructive way, as you can hide or delete the grey layer and restore the image to its original tones at any time.

Dodge and Burn

Traditional darkroom photographers were able to vary the tones In their monochrome prints by changing the amount of light that hit particular parts of the photo paper during the development stage. By holding a piece of card in front of certain areas they could selectively reduce exposure time and burn in darker tones. By creating holes in the card they could Increase exposure time and dodge in brighter highlights.

Tips

When spraying a black or white brush on a Layer Mask to reveal or hide the attached layer’s pixels, tap the right square bracket key to increase the brush tip’s size so that you can edit a larger area. If fine-tuning fiddly bits, tap the left square bracket key to shrink the brush tip. The tip’s size will be displayed in the options bar.

In step 12, we used a Levels Adjustment Layer to brighten up the girl while leaving the rest of the shot’s tones untouched. To quickly reduce the intensity of the adjustments, simply click on the Levels Adjustment Layer’s thumbnail and reduce its Opacity to 80%. The non-destructive nature of Adjustment Layers enables you to fine-tune your edits with ease.

Because you’ve dodged and burned on a separate layer you have more control over the image’s tonal range. You can click on the Dodge an Burn layer at any time and continue fine-tuning its highlights, midtones or shadows safe in the knowledge that the Background layer’s original tones remain untouched. Click on the Dodge and Burn layer’s eye icon to toggle it on or off to compare the edited tones with the original.
