Hi Mack
Your mention of using a frame makes me wonder if multiple frames might work - almost.
Let me go into a little more detail of what I'm trying to do. Bear with me because it might take a little time to get to the point.
Before I begin a project, I like to try and collect together all the resources that I'm likely to need. Ths includes things such as graphics, animations, sounds, etc. Where I expect to use display text, like page titles, etc. for consistency I create a template for the object, including as required: fonts, sizes, colours, borders, backgrounds, transitions, and text animations, etc. With that done, I make a project-specific Gallery to which I copy these objects.
Next I make all the master pages likely to be used. I've just completed making some 50 all with themed images. (I'm almost back to the main point
)
I often use your suggestion of overlaying an object with a solid frame with variable degrees of transparency. That is very effective at reducing the intensity of an object, and I think it would work well in a multiframe.
But I want to do more, and that's where I think the difficulty will arise.
For example, suppose I have an image of a street lamp, illuminated at night. What I want to do is to initially show this as a blurred object, perhaps giving a halo effect around the light, and then gradually removing the halo and sharpening the lamp as the focus adjusts.
I'll also experiment with several concentric circles, each with slight colour variations from the central final focus. By playing with various special effects, perhaps I can create the initial blurred object that imitates a camera focusing to a sharp result.
I'm sure there is a solution within Opus -- I've yet to not find a solution to issues like this. Opus' flexibility is one of its great strengths.
Thanks again Mack for your useful suggestions.
