Question may i know if kuyper luminocity masks are 16bit?

hi

may i know if the tony kuyper actions/panal create 16 bit or 8bit luminosity selection ?

for example i open a image ,it's a 8bit image and i keep working in 8bit more

now i use kuyper panel v4 or v3 , does the panel create 16 or 8 bit luminocity masks?

i have read http://goodlight.us/writing/actionspanelv4/panelv4.html and https://tonykuyper.wordpress.com/201...inosity-masks/

but honestly i did not understand the webpapes linked


thanks

The action panel creates 8 bit luminosity masks regardless of the image bit depth.

Mantra, have a look at Greg Benz's 'Lumenzia'. Also works in 16 bit depth, search either under 'Greg Benz' or Lumenzia.

AFAIK any 16 bit mask when applied as a selection will still be an 8 bit selection due to the way Photoshop works.

To stay in 16 bit would require use of Apply Image command

And the masks are created in 16-bits, allowing for smooth transitions in extreme masks.

ILM does not use selections to create the masks which allows ILM to create true 16bit masks (in the case of 16bit images)
in short i can not understand if they does use Apply Image command to create maskes
thanks

Hi Mantra
Not sure how the new masks are actually formed in version 4 but can certainly accept that they are true 16 bit.

The old method used channel selection steps that are 8 bit (hard wired into PS)

If I understand correctly the newer method of making the masks is indeed a full 16 bit workflow, however when the mask is applied it has to be applied in 8 bit due to the way PS is hard wired.

While the 16 bit masks may be smoother it may not be apparent in many image manipulation scenarios. However given the choice I would opt for 16 bit as it could not do any harm (AFAIK)
