Re: Re: Lab-WOW -How to use it ?

With an interactive tool I still think adding the layer is the most
efficient (although trivially so). I think you are assuming that you
would boost the effect more if it were a layer, so you could achieve the
desired effect. I don't think this would be required. If you like the
effect as it is, you simply leave the layer mode as "normal" and then
flatten the image. Otherwise you can change the layer mode (or opacity)
to anything you want and then flatten the image. If you create another
image but want to combine with the original, then creating another layer
on the original image and copying the resulting labWOW image to this new
layer is more work. As I said, I think the difference is trivial.

On the other hand, if we're not talking about an interactive tool (i.e.
if we want to use this in batch mode), then I think you would want to
create a new image since you won't have the visual feedback you would
want if it were a layer.
