ImageReady / animation question

Is there any way to adjust the brightness of this animation in ImageReady?? As you can see it's way too dark. I've been trying since yesterday to figure out if it's even remotely possible but so far no luck. (I checked the memories but couldn't find anything) The whole being-a-newbie-at-ImageReady thing isn't helping either. So.. anyone?

(let me know if this is the wrong place to ask this question)
