Adjustment Layers – Easy one!

[Ian Collister] “How do i get an adjustment layer to only effect the layer, directly beneath it, rather than effect every layer beneath it? “

There are a couple of options here. 1) Apply your effects directly to the layer instead of using an adjustment layer. 2) Pre-compose the layer you want to affect with the adjustment layer. 3) Duplicate the layer that you want to affect, place it above the adjustment layer and use it as a track matte.

Some of these options will be better or worse depending on what it is exactly you’re trying to do. I listed them in order of my preference.

Strictly speaking, that can’t be done. What Darby suggests creates the situation where either a) you avoid using an adjustment layer, or b) you make sure there’s only one layer below the adjustment layer in some fashion. Sort of.

Since adjustment layers are supposed to be used when you want to affect more than one layer, there’s no point in using one when you only want to apply efects to one layer. Just apply the effects directly to the layer in question (as Darby recommended) and delete the adjustment layer altogether.

I agree in principle, but certain effects will behave differently if you apply them to an adjustment layer instead of the layer itself. For example, Trapcode’s Shine effect when applied to a layer will clip at the layer boundaries, but if its applied to an adjustment layer above the layer it will extend to the boundaries of the adjustment layer (which is usually the composition size).

I don’t generally encourage the use of adjustment layers in this way, but it can be helpful in certain circumstances.

If you can apply the effect directly to the layer, then that’s what you should do!

Ah, of course. I had forgotten about that, having grown (!) accustomed to using the “grow bounds” effect.

Thanks all, much appreciated!
