I ran into this major bug while re-organising my mobile shots and I consider it serious enough to share. In short, if you are using date/time functions in the Lightroom import, you have to be careful and double-check to make sure this bug does not impact your catalog.
Let us see what this bug is and how it can create chaos in our catalog.
Photoshop has built-in actions for a variety of functions that not many people that I know of actually use.
Not that I personally use those a lot, but, these built-in actions can save a huge amount of time if you need to do anything similar.
Before we look at the actions, there are a couple of points to keep in mind…
If you invoke Photoshop from Lightroom, you will get all kinds of errors and this is definitely a bug in the Lightroom-Photoshop workflow.
In case you get any errors while running these actions, just reset the settings for Photoshop by pressing CMD+OPT+SHIFT and then clicking on the PS icon to start PS. You will be prompted to reset the settings and just click okay on that.
Now that we are done with the issues, let us take a look at all the goodies we have already built into Photoshop.
To my way of thinking, working with layers implies the ability to precisely mask areas or subjects and apply effects based on the selections or masks.
This is exactly what makes the Luminar 4 layers practically useless. The implementation of the masks/selections is similar to using a paintbrush app vs something like Photoshop.
In Luminar, you only have the fixed brush and gradient tools for the masking. There is no option of something like an edge/tonal detection auto-mask (as in LR) or the perfect brush in ON1 Photo Raw 2020.
This means that you cannot really do clean masking or selection of any subject. Since you cannot make a clean mask, the whole purpose of layers is defeated.
Although there is a luminosity mask in Luminar 4, the same issue makes it practically useless. There is no control over the luminosity mask as in LR (which is not great) or ON1 (which is far better than LR).
While Luminar 4 remains a choice over LR and ON1 for noise reduction and the AI-based image enhancement features, the layers can be ignored almost completely.
The only place you can use layers is when you have shots where you can apply one of the blending modes in Luminar 4 and achieve the effect you want. Other than that, forget layers in Luminar till they have better masking tools.
