Tutoriel: AKVIS Enhancer

The Golden Pavilion

Désolé, à présent cette information n'est disponible qu'en anglais. La version française sera bientôt affichée.

The author of the tutorial is Manfred Zobrist.

The Golden Pavilion in Kyoto/Japan was processed in the Lightness channel of the Lab color space.

The original photo of the Golden Pavilion is too dark. I tried to keep the delicate cloud pattern in the sky, but consequently the photo came out underexposed. It was strictly prohibited to use tripods, so I could not take several shots with different exposures. The Highlightes/Shadows in Photoshop did not deliver the desired effect. Finally I tried the AKVIS Enhancer 9.5 plugin and it was able to cope with the problem and improve details both in dark and light parts of the photo.

Original Result

Step 1. Install AKVIS Enhancer on your computer. I used the plugin version with Adobe Photoshop CS3. Open the photo to process.
Step 2. You are working now in RGB color space. To achieve the best result, switch to the LAB color space and choose the Lightness channel. In this way we will avoid color and luminance noise. As we work in the Lightness channel, the photo is displayed in black and white.
Step 3. Set Preview Size to 1 and the image scale to 100%. In this way you can control the influence of the filter on the image. The Enhancer mode is already active by default. The workpace should be opened to the full size.
To check the result on individual parts of the image, press the space bar (the cursor will convert into a Hand tool) and scroll the image with the left mouse button pressed. If you want to compare the result and the original image, just left-click on the result.
Adjust the parameters as you like. In this case I reduced the Level of Detail to 3, to not spoil the sky. I also reduced Lightness to 22. You can save your settings as a preset, if you want to use them in the future.
Step 4. Once you have chosen the settings, click on the green check mark to apply the filter to the image and close the plugin. Then switch again to RGB-Modus (the command Image->Mode->RGB. Now the photo is displayed in color.

Here is the result. Not only are the green plants on the left visible, the woods in the background are easier to discern. The gold of the pavilion shines and even the lower part of the pavilion (not gilded) is visible too. What I like about the result is that no details in the sky have been lost.
