When using DECIM8, we start with an original image then create an effected version of it. The effected version is layed over the original, with a certain amount of transparency, and with a specific blending mode:

When you're looking at an image in DECIM8, you are seeing the base image, with the effected version on top. By moving the transparency slider, you can change how much of the effected image is shown. By selecting different blending modes, you can change how the effected image is blended with the original.
The effected image is created by taking the original image, then applying whatever effects filters you currently have selected, in the order you have them arranged (see EFFECTS ARRANGE below). You may have one or more filters enabled that cumulatively create the effected image.

If you tap the EFFECTS ARRANGE button, you will be shown this view. Here, you can activate individual effects by tapping them. When they are highlighted with the aqua color, they are selected, or "on".

DECIM8 contains 18 different blending modes, defining how the effected image is blended with the original image:
