I have followed the "Displace Filter" Vimeo instruction video faithfully, but I made 1 mistake :

I chose the "Screen" blend mode from within the Live Filter in order to make the black text turn white.

 

That didn't work, the text stayed black.

 

Took me awhile to figure out what I was doing wrong, in the end it turned out that I must choose the

Screen Blend mode from the Layers panel. Only then does the black text turn white.

My bad, of course.

 

My question, though is : what is the difference between the Screen blend mode within the Live Displace Filer

and the Screen Blend mode in the Layers panel. For there is clearly a difference.

And is this the case with the other filters, also ?

Thanks in advance for you clarification !

Best regards,

C.L.

The blend mode in a Live Adjustment Layer changes how the pixels applied with the filter interact with pixels in the layer below.

 

When a layer is using a blend mode from the Layers Panel drop down it will affect how the layer's pixels or contents blend with pixels in the layer below.

 

Hope this makes sense!

Leigh,

Thank you.

Uhmmmmm.....

I'm trying to get my head round it (but not succeeding, I'm afraid...sorry !)

Live Adjustment layer : pixels applied interact with pixels in layer below.

Layers Panel : pixels in layer blend with pixels in layer below.

Isn't that the same ?

Cheers,

C.L.

if i understood how blend modes work, it's the same thing.

the blend mode rules how the pixel in the layer interact with the pixels in the layers beneath. it doesn't matter if the layer which the blend mode is applied to is a pixel layer, an adjustment layer or a live filter layer: each blend mode has an algorithm associated with it, and this alogrithm is applied, no matter what kind of layer it is.

take care,

If I am understanding this right, I believe this is a hierarchical question.  Changing the blend mode of a layer at the main level, will affect the layer below it at the same level.  Have a grouped layer (for example), the embedded layers blend mode will affect the layers below it at the same level.  But won't have a DIRECT affect on the layer at the main level below it.  

So if you look at an FX as an embedded layer of the layer it is attached to, the FX blend mode will directly affect the layer below it, at the same level. But is still bound to the parent layer's blend mode on dealing with the layer below it at the main level.

Of course, I may be wrong.
