 Effects Section

The effects window consists of 5 sections (Input, Filter, 3D Light, Layer, Color) connected by arrows. These arrows define the data flow (e.g. Filter comes before 3D Light). Of course all effects can be explored in random order, the arrows simply illustrate their routing.
Note that the effect section works for both still images and movies.

Input
The first section, input, selects either an image or video from the gallery or allows to use an image of any (even non-mystica) source by clicking paste.
 

Filter
Next comes the filter section. There are three items to play with:

  • Filter Type: Selects the filter kernel being applied to the image

  • Kernel size: Defines the influence of the filter. Note that this depends on the image size, large images need high kernel sizes

  • A slider blending between the original image and the filter-altered image

Here is an example:
 

Assume this input image (.mys). To enhance,
we try to emphasize the irregular stripe pattern.
This will add a nice texture to the otherwise too
smooth design.
 
We achieve this by using an edge filter, in this
case "edge2".

A high kernel size is selected as we want a broad
edge effect rather than local bumps.
The upper image effect was obviously too strong.
We now blend the effect of the edge filter with
the original image by moving the blend silder more
to the  left.

Finally, the original image is slightly enhanced.


3D Light
The 3D Light section computes a 3D profile based on the pixel brightness and allows to light this profil with respect to different parameters.
The lighting works best if the previous filter section uses the "soften" filter.


Depending on the light direction, holes and bumps can be inverted. The light and shadow color colorize the image. usually, the light color is chosen to be bright and shadow dark. Try dark light colors to dim the image in those areas facing the light.

The following "Material" slider defines the specularity of the 3D profile. Usually you will choose rightmost positions to give the image more depth.
As with all effect sections, the last slider blends the effect result image with the original image.


Layer
This section allows to composit images of any source. It is enabled by pasting an image. The simplest example is: click "copy image" in the effects output section and "paste image" in the layer section. You will see the image itself superimposed.

Use the zoom slider to resize the pasted image. In cunjunction with the layer mix mode (add, sub, xor etc), different designs will result. To reduce the effect, use the brightness slider.
There is no typical sequence in using layering - simply play with all controls.

To get a layer ontop of an existing layer, click "copy image" in the effects output section and click "paste image" in the input section. Now the two previous layers from a new image which can be layered again.

Note that this layer section can be used to blend some copyright information or your name into images and onto each movie frame.


Adjust
The section offers the usual brightness, contrast, and gamma sliders.
