I need to add photo descriptions to photos, so basically add text to photos. These are color and black and white and have all different backgrounds/colors etc. So i need to create some type of banner along the bottom, i would like to make it opaque to a point and have the text inside the box. how do i do this in lightroom? I am a newbie as i just downloaded it today.
You can do this in either the Slideshow or Print modules and export from there.
Look at the online manual and AdobeTV for free tutorials.
