The Metallic transition, found in the NewBlue Art Blends collection, is a lot of fun to work with. You can warp the first image into twisted metal and then warp  back out into the second image. 

Also there are some unexpected things you can do with it if you play with the controls.

Start with a simple dissolve transition between two images.

Drop the Metallic transition on the first image and select the Halloween preset . . . 

which gives the flower a metallic shine with an orange tint.  

To change the characteristics of the metal, use the Highlights and Calibrate controls.  

Highlights sets how busy the metallic reflections become-- “crinkle factor”--the higher the setting, the more it looks like crinkled foil.

Turn Highlights down and the image becomes simpler with fewer highlights.

Turn it all the way down and the metal look is gone.

Now, play with Calibrate.

In using Calibrate, you will be setting the offset for the mapping of dark to light--used by the transformation into shining metal.

However, if you turn Highlights all the way down, you set a very simple gray scale mapping.

To use the mapping creatively, turn Calibrate all the way down for an inverted image, much like a black and white negative. Turn it back up to 50 to map the gray scale correctly.

You now have a high contrast, sepia toned transition.

To change the color and contrast, use the Shine and Color controls.

Select a color either by clicking on the colored button to open a color chooser, or by clicking on the ink dropper. 

If you borrow a color from the picture using the dropper, when you click on it, the video picture in Vegas turns back into the image of the flower. This allows you to choose a color directly from the original image.

Move the dropper over the flower and choose the light pink in the petal.

Now the image is a high contrast grayscale image with a pink undertone to it. Note: it keeps a subtle amount of the original colors, as set by the Picture control, which you can adjust to fine tune the blend. 

You can also adjust the image contrast by rotating the Shine control. Turn it down to reduce contrast and flatten the image.

Just for fun… turn Highlights all the way up.

Hmmm… what do you think?
