This Effect transforms your image into an explosion or firework display. There are many things you can alter to get very different effects.
As usual the best way to see what can be done is to let the Wizard choose and push F8 a few times. You can choose the center of the explosion by clicking on the preview image, and in the dialog box you can change:
Colors
| • | Choose if the starting and ending colors originate from the original image or not. |
| • | Choose the starting and ending colors of the tracers of the explosion. |
| • | You can choose the background color(s) , or set the background to the original image. |
For example each trace could always start with the color of the original image at that point, and end in red. In that case you'd click on (checked) Start with image , click off (unchecked) End with image, and then choose a red color with the select button.
Form
| • | You can select how many tracers will be in the explosion using the Number of tracers edit box and/or slider, |
| • | You can change the trace length using the Trace length edit box and/to slider. Measured as a % of the diagonal size of the original image. As if you care. |
| • | You can change how big the end of the tracers are using the Trace ending width controls. Tracers start thin and can grow larger towards the end. Big deal. |
| • | The Gravity effect slider will force the tracers to head for Earth (bottom of the image). A gravity effect of 0 is like an explosion in space. The tracers just shoot out from the center without falling to Earth. |
NB: If you deselect Start from image and End from image then the resulting image will have next to nothing to do with the original. But you might get some nice fireworks effects.
