To add emphasis to a Call To Action button, I created a template where the button is larger that the body of the actual main content area.
For the program title text, I incorporated the logo that I had created in the Typography Workshop (see previous post).
For the episode title text, I set this against a silhouette of a narrowboat (using same technique as previous banner ad, but this time blending a coloured layer to get the required colour that matches the background)
For the Call To Action button, I played around with the bevell, emboss, drop shadow and glow effects to make it look like a clickable button.
I have used the blend tool on the body background to add depth. The depth is also enhanced by the glow around the boat.
