This is an script developed for Macromedia Fireworks, that applies some action in a picture, to get an Pseudo HDR effect to improve dynamic range of light.
The creator of steps to get the effect on Fireworks, is la100rra in his post Pseudo HDR en Fireworks - Tutorial (spanish).

I only took that excellent tutorial, and create the script that automatizes all the steps.

I have tested the script with Macromedia Fireworks 8 and Adobe Fireworks CS3.

1. Open the picture and enter Commands menu and select to execute command file...

2. Select the script and click Open

3. Wait just a second... and you are done! These are examples of results obtained
