I am using Altitude Pro. How do I remove the dark overlay from the (front page) images?

In your theme's style.css around line 1250, you'll find the following:
The "darkening" of the images is achieved by the linear gradients. To remove it, simply delete or comment out those lines.
How do I make the overlay in Altitude Pro lighter?
If you look at the background directives in the .image-section class, they are all defined using rgba color values. In CSS, the rgba directive requires four parameters. The first three define the rgb color value. The 'a' or alpha channel defines the opacity. A value of 1.0 presents the color at 100% opacity. Any value less than 1 decreases the color's opacity (makes it more transparent), in effect making it lighter.
