There is one thing you need to be aware of when it comes to order and that is when applying presets.
Presets come in two main flavours - partial and full.
A partial preset will only contain certain adjustments - basically it is a “batch” of adjustments all applied at the same time. PL Elite allows you to create your own partial presets, that will allow you to do a certain set of adjustments so, if you always tend to do the same series of adjustments, these can come in useful.
As long as you know what a partial preset does, you can apply them at any time.
However a full preset will tend to reset a lot of adjustments at the same time as it applies others. In which case, if you don’t know what exactly a preset does, only ever use it before you do anything else.
If you are considering adding FilmPack, then @mwsilvers and I have put together a bundle of partial presets, which will allow you to preview what each film emulation does. You can find it here but do be aware that you will also need to download FilmPAck in order to benefit from them.
