Using AI masks ... Je ne comprends pas!

Here’s my starting point;

  • As an exercise, I want to use AI-masking to remove distractions in the background

So, I try;

  • without success; image

No problem - I’ll select the flower(s) instead, and invert the mask …

This is the part I do NOT understand … How can I now add to the AI-Flower-mask (without having to resort to manual masks, such as Brush) ??!!

  1. With AI mask (Flowers) selected, I click on the “Add an area” option;
  • I click on the buds - A new AI-mask is created - with no obvious selection associated with it !!! … Nope, that’s no good.
  1. With AI mask (Flowers) selected, I try the “Add a selection” option;
  • Am I now supposed to be able to draw a rectangle around objects - for the AI selection to focus on ?? … Nope, that doesn’t do anything useful !!
  1. (After deleting all the spurious/useless masks and sub-masks created by attempts 1 & 2) I try selecting the original AI mask (Flowers) again - and this time I click on “New sub-mask” … and I re-try different variations of 1) & 2) … Nope, I’m getting nowhere !!

Is this supposed to be possible ? … What am I not understanding ?!

can you put a raw link up drop box whatever? Not exactly sure what your trying to do ive been doing heap of rodeo edits recently probably not sure 300 images and various masks have been working fine in tricky situations. And above you would think theres enough contrast to pick up the buds cheers mate

Can do - but, it’s more the general question that I’m asking … How are these “additive” AI options (Add a Selection & Add an Area) supposed to work ??

If you shift - click using the object selection AI tool you can add objects to a single mask.

Ahhhh - Yes, that works - Thank you.

But

  • How are we supposed to know that (I cannot see it listed in the pop-up) ?

  • What then is the purpose of the Add/Remove a selection & Add/Remove an Area tools … How are they used ?

I don’t know how we are supposed to know - have you read the documentation? It’s online somewhere. With the add/remove area one draws a rectangle around a number of objects to select them. Experiment also with the alt/opt key for removing sections or part of thereof..

all good couldn’t work out what exact problem was thats all. im finding masking is working well

Thank you Jeff

Now I can select multiple flowers :grinning_face_with_smiling_eyes:

Your next challenge, should you be willing to accept it, is to mask out all the sky parts in this image, using AI masks…

My attempt…

Whereas, with a Control Line, it’s oh so simple…

I would only use a control line here and not an AI mask. Life is too short!

Ahhhh (again, Jeff !!) - - I was expecting “Add a selection” to work that way …

  • based on indication of the tool/gizmo icon; image !!

My conclusion, re AI-masks, is that they’re really handy for quick-and-easy selection of obvious & simple objects/areas … but, for anything complex, they very soon get overly complicated and cumbersome … not just in their usage, but also in the long (essentially unmanageable) list of masks and sub-masks that they generate.

Yes, I have been reviewing the doco as I’ve been exploring AI-masking capabilities - but I had not “absorbed” that nuance.

To be fair to DxO’s documentation team here’s the reference, which I found by “reverse search” (in that I searched for what I now know to be the answer :wink:)

I can’t agree more!

Use the right tool for the job. PL has many options for masking and I am sure one can find the tool, or combination of tools, to do the job. I have no issues with masking.

If you have really complex editing to do then use something like PS or Affinity after initial processing in PL.
