When taking photographs in certain lighting conditions, such as on a dull, overcast day, your location’s colours may be less than striking in your final image. In our start image, for example, a burst of flash has brought out the colours of our model’s clothing, make-up and skin tones, but the rest of the shot’s colours are rather drab and desaturated. The location’s flat-lit colours - like the boring brown brickwork in the background - may be weaker, but they still distract the eye from our main subject. There is a solution.

In this walkthrough we’ll show you how to use Photoshop Elements to desaturate the shot’s weaker (and largely irrelevant) background colours to create a more moody monochrome urban scene. You’ll then discover how to apply brush strokes to a Layer Mask to restore the model’s vibrant colours so that she stands out more effectively against the monochrome environment. By making selective colour adjustments in this way you can emphasise the shot’s strengths such as the attractive colours of the flash-lit model while desaturating the location’s weaker colours.

We’ll also show you how to make selective tonal adjustments so that the brighter model stands out even more against the darker background. By using the Burn tool to darken specific tones you can also hide some of the room’s busy and distracting details and add a sense of mood and mystery to the simplified scene.

To add a gritty texture to our urban location we’ll also demonstrate how to use filters, layers and Blending Modes to give our clean, digitally-sourced start image a film-style grain. This analogue look helps make the shot look more ‘street’!

Spray the black brush on the white mask to poke a hole through the monochrome layer and reveal the girl's colours on the Background layer below. If you reveal unwanted background colours by mistake, press X to toggle to a white foreground colour and spray to restore these areas to monochrome.

5.    Re-colour the girl

Keep spraying a black brush over the model to reveal her skin and clothing colours - don't worn/ too much about editing all of her jacket, because it only has a hint of colour in the leather's shiny specular highlights. Using this technique you can restore the rest of the model to full colour.

6.    Fill with grey

Choose Layer>New>Layer. In the New Layer window's Name field, type 'Dodge and Burn'. Click OK. This creates a new transparent layer called Dodge and Burn. Go to Edit>Fill Layer. Select 50% Grey and then click OK. Set the Dodge and Burn layer's Blending Mode to Overlay.

Choose the Burn tool from the Tools palette. Grab a soft-edged tip from the Brush Preset Picker and set the Size option to 600. Set Range to Shadows and drop Exposure to 15%. Spray around the edges of the frame to darken the shadows and hide the interior's distracting architectural details.

8.    Add drama

To tease out more detail in the clouds, set the Burn tool's Range option to Midtones. Keep the Exposure option set to 15% so you can edit the clouds in gentle and controllable increments. Spray the Burn tool over the clouds to darken the midtones and make the cloud texture look more prominent.

9.    Lighten the midtones

The girl's dark jacket blends too much with the shadows, so to help her stand out from the background choose the Dodge tool from the Tools palette. Set Size to 125 and Range to Midtones. Keep Exposure at 15%. Spray behind her head and jacket collar to lighten the midtones of the roof a little.

10.  Copy and Paste a mask
