Ctrl+Shift+Clicking Thumbnail?

[makspyat]

Hi Everyone

it seems that Ctrl+Shift+Clicking the rasterized layer's thumbnail does not select all pixels with luminosity above 50% which is a very common practice to create a luminosity mask.

The same combination is working in AP 1.6.5 - so please fix!!

Hello @makspyat,

Try the keyboard shortcut CTRL + ALT and left mouse click on the thumbnail.

Hi all,

To re-open this topic,neither of the alternatives mentioned work on my version of 1.7.0.367. Have tried with both 16 bit and 8 bit images; same (lack of) result. Is there something I am missing? (Windows 10 64 bit)

Thanks.

You can also keep adding luminosity selections from other layers by holding down shift as well. Can be pretty handy from time to time.

Thanks FDK for your very swift response. Unfortunately no combination of Ctrl+Shift or Ctrl+Alt or even Ctrl+Shift+Alt while clicking works for me for selecting luminosity pixels above (or below) 50%. However, if I am using the selection brush I can select multiple points via Ctrl+Shift.

Did you try making a new layer and fill the canvas with colour to see if the selection worked (works also with Create New Fill Layer in the Layers menu at the top of the screen)? If not, then maybe report that as a bug.

[aaturner]

Yup, tried that with no success, so I shall follow your good advice and report the behaviour (or lack of) as a bug.

I found no combination for making luminosity selections.

Hello @curtj,

The selection of a luminosity selections works very well.
Try the following:
With the shortcut CTRL + ALT and left a mouseclick on the thumbnail,  a selection is created.
To further narrow down the selection.
Activate the layer with the selection and make a duplicate,  wiht the shortcut CTRL + J
Activate the new layer and deselect the selection, wiht the shortcut CTRL + D.
With the shortcut CTRL + ALT and left mouseclick on the thumbnail, it will a  further luminosity selections created,
the selection is reduced by ca. 50% .

To use the selections for further processing steps, create a spare chanel of the selection.

 

Cheers

I’m using a MacBook Pro, I noticed you said CTRL + J to make a duplicate layer (Windows), is there a different key or keys sequence for luminosity selections on a Mac? To make a  duplicate layer on a Mac I use Command + J.

Thanks

Sorry.
CTRL in Windows should be Command (CMD) on the MAC.
With the shortcut CMD + ALT and left a mouseclick on the thumbnail,  a selection is created.

Please, just try it.

Many thanks to both Gnobelix and Cecil for you solid instrutions! I wasn't thinking about the Mac and Windows differences.

Hello, I am trying to make a luminosity selection by doing CNTL+ shift + left clicking on the thumbnail.  All I get is the whole layer selected.  If make a curves layer and Alt + click on it the layer is completely white so it is clearly not working.  What am I doing wrong?

Thanks

Windows:

Ctrl+Alt + left-click (the thumbnail)
