During the slideshow you can capture and manipulate the current image with the effect at its native size. When PhotoChances saves an image with an effect, additionally it embeds in the file the "recipe" used to transform the image. This provides a source of many unique effects that you can collect for later use with any picture: When you want to replicate an effect in an image to some other it's as easy as dragging the image file previously saved.
Apart of embedding the recipe of the effect inside any image it saves, the program allows optionally saving the "recipe" of the current effect in a special location for quick access. This location is called the "Store of effects"
To capture the image you are viewing press the space bar, this will open the Lab Window loaded with the current image and effect. Here you have access to all the features of the edition and management of the program. Press the button "Save Image" to store the current image in your disk. See here all the details about the lab window.
To use the effect in any picture capture previously, run PhotoChances Lab, drag the saved file to the top zone of the lab window (or use the button "Load effect from image") and drag the image you want the effect applied to the centery zone of the window. (Or use the button "Load image").
