134 ADVANCED PHOTOSHOP ELEMENTS 5.0 FOR DIGITAL PHOTOGRAPHERS<br />

IMAGE CHANGES –<br />

BEYOND THE BASICS<br />

Those of you who are intimate with Elements will no doubt be asking ‘Why not just use the Fill<br />

Flash or Shadows/Highlights feature to fi x this underexposure problem?’ and you are right to<br />

ask that question. <strong>The</strong> Fill Flash option is a great tool for lightening mid to dark tones that have<br />

plenty of details, but I have found that this ‘duplication layers’ technique provides a more pleasing<br />

result for underexposed images with little shadow information.<br />

Solving exposure problems when shooting<br />

<strong>The</strong> statue picture not only provides a great example for this<br />

technique but also demonstrates how such underexposure can<br />

occur. Set against a white overcast sky this dark statue was<br />

underexposed because the camera’s meter was fooled by the bright<br />

sky behind the subject and therefore provided a shutter/aperture<br />

combination which was too dark. <strong>The</strong> thinking photographer<br />

would have predicted this problem and used the Exposure<br />

Compensation system on the camera to increase exposure by one<br />

to one-and-one-half stops to adjust for the back lighting. Most<br />

mid range digital cameras and above incorporate an Exposure<br />

Override system like this.<br />

To try this for yourself, the next time you encounter a back lit scene shoot two pictures – one<br />

with the camera set to auto and the other where you have added to the exposure. Compare the<br />

results later on the desktop, or better still, check your exposure in the fi eld by examining the<br />

histogram graph of your image on you camera’s monitor. This graph works exactly the same<br />

way as the graph in the Levels feature in Photoshop Elements. It displays the spread of tones of<br />

your image across a grayscale from black to white. Underexposure will result in a graph that<br />

bunches towards the black end of the spectrum whereas overexposure moves the pixels towards<br />

the white point. A simple check of this graph when shooting can indicate whether you need to<br />

adjust your camera and re-shoot to compensate for an exposure problem.<br />

Step 1 >> With the image at 100%<br />

magnifi cation apply the Add Noise<br />

fi lter with Uniform/Monochrome<br />

settings.<br />

Step 2 >> Select Burn-in tool, reduce<br />

exposure to 10% and choose mid<br />

tone range. Set brush size and edge<br />

softness.<br />

Use the camera’s Exposure<br />

Compensation system to override<br />

your camera’s settings.<br />

Step 3 >> Burn-in the white area<br />

using several overlapping strokes to<br />

build up the effect. Change to Shadow<br />

range and repeat if necessary.
