How to make a drop shadow in UF, for beginners.
When I look at good UF fractals I sometimes see a shadow effect that is very realistic.
I didn’t know how to do that so I imagined a way.
I don’t know how other people do it but this is what I do.
When you make a layer with transparent parts (the white parts of Fractal 1 above), it’s easy to make a drop shadow on the edges to give relief.
It works for masked layers also and for orbit traps, with a different position of the shadows.
Duplicate the layer with transparency.
Go to the lower layer, hold down the Shift key and click on the magnifying glass + between the two little blue boxes in the Fractal Properties box. It isolates* that layer to work on.
Right click in the gradient box and choose Select All. All the nodes will be selected.
Go to the Luminance part of the gradient, click and hold one node and drag all the points down to the bottom for a sharp black shadow (Fractal 2) and half way down for a soft shadow. (Fractal 3)
(You can Invert Selection now in the same place if you like… not important.)
On your keyboard, hold down the (ctrl) key that allows you to pan. Drag the layer very slightly down, or to the side and a black shadow will appear at the edges.
You can also rotate (option key) this layer a little for a different effect.
Hold the Shift key and click again on the + icon to activate all the layers.
There is also another way to create a hard or soft shadow.
Isolate* the lower duplicated layer and drag down Luminance as above.
Select the Zoom box and drag its edges to a size a little smaller than the fractal.
This gives an external shadow from a central light. (Fractal 4)
It can be sharp or soft with the same method as above.
You can make an internal shadow by moving the Zoom box edges larger than your fractal.
There are other methods I don't know yet.
I hope this can help beginners.
