Duo-tone Experimental

What does anyone use all these different utilities for that are provided with Picasa?

To communicate better than it is necessarily possible with a digital camera that resists some variations in light and as an example serves up sunsets that mean we learn to interpret what we are shown. Interesting that our interpretive faculties are becoming increasingly sophisticated as we manage new technology. We are learning a new language.

I am, anyway. I am interested in social media from the viewpoint that it is facilitating change. The masses can try their hand at discovering how the professionals create great effects. I've not found any application for Duo-tone before that has meant the elements of the story of the image remain discernible.
