|
|
the purpose of the mask is to hide parts of the image
|
|
|
|
** setup a mask
|
|
1. select the text
|
|
2. click on the mask button in the layers pane
|
|
- this will add a white square to the right of the text entry
|
|

|
|
|
|
The concept of a layer mask is that
|
|
- black areas are hidden
|
|
- white areas are shown
|
|
|
|
so select the layer mask and draw with black on the center panel to hide or show areas
|
|
|
|
*** to hide and show the layer mask
|
|
- hold the alt/opt key and click on the layer mask
|
|
- you can also click on any other layer, or outside the layer mask to hide it
|
|
|
|
** reason 1: non destructive abilities
|
|
while you can certainly delete parts of an image and putting something else in it's place, you cannot undo that deletion so easily.
|
|
|
|
1. select the area you want to show
|
|
2. hit the mask button (this will automatically hide everything not selected)
|
|
|
|
*** hide the selected area (2 methods)
|
|
|
|
**** method 1
|
|
1. selecte the area you want to hide
|
|
2. select->inverse
|
|
3. hit the mask button
|
|
|
|
**** method 2
|
|
1. select the area you want to hide
|
|
2. ALT/OPT + mask button
|
|
|
|
** compatibility with non raster layer
|
|
|
|
1. place an image on top of a background
|
|
- Photoshop->Settings->General->Always Create Smart Objects When Placing
|
|
- the image is going to be selected as a mask
|
|
|
|
2. go to the backround layer, select subject the subject
|
|
- note that "select subject will be highlighed"
|
|
- [[../_share/media/img/photoshop-beg-piximperfect/lesson4-1.png]]
|
|
|
|
3. return to the imposed layer and create a negative mask
|
|
- alt+mask button on layers
|
|
|
|
4. at this point you can blend the layers if you like
|
|
- double click top layer, you'll open to blending options
|
|
- move the sliders in underlying layer to get what you want
|
|
- if you hold down the ALT key, and hover over the slider, you can split and drag it
|
|
|
|
** linking and unlinking layer masks
|
|
if you want to move the pattern around, you'll see a problem of the mask moving with the pattern.
|
|
|
|
this applies to normal transformation
|
|
it also applies even to filters such as blurs. ie, the blur will affect the shape of the MASK ITSELF
|
|
|
|
the way to unlink or unlink is to click on the link icon that connects the mask to the image
|
|
|
|
** turning on and off mask
|
|
- hold Shift key and click on the mask, a red X will appear on mask
|
|
|
|
** mask properties: feather
|
|
- bring up properties panel on mask
|
|
- double click on mask
|
|
- select mask and click the properties button
|
|
|
|
- find the feather slider and change it
|
|
|
|
** mask properties: density
|
|
|
|
*** apply color lookup mask to subject
|
|
**** method 1
|
|
- add a the 'color lookup' filter
|
|
- select subject from image layer
|
|
|
|
- =OPT+DELETE= apply mask to color lookup layer
|
|
|
|
- =CMD+D= deselect the selection
|
|
|
|
- =CMD+I= invert the mask
|
|
|
|
**** method 2
|
|
- select subject
|
|
- add a 'color lookup' filter
|
|
- this will automatically apply a mask to the selected area
|
|
|
|
*** decrease the opacity of the mask on the rest of the layer
|
|
- open up properties
|
|
- slide the density to be lower or higher
|
|
|
|
** duplicate masks
|
|
|
|
*** create a new overlay layer
|
|
- =CMD+SHIFT+N= create new layer
|
|
- choose blend mode 'overlay'
|
|
- click the check box to "fill with overlay-neutral color 50% gray"
|
|
- overlay blend mode hides anything that is 50% gray

|
|
|
|
*** convert the overlay layer to a smart filter
|
|
- select the overlay layer
|
|
- =Filter->Convert for Smart Filters=
|
|
- =Filter->Noise->Add Noise=
|
|
- set the noise to 30
|
|
- =Filter->Blur->Gaussian Blur=
|
|
- noise is to fine, we need to blur it
|
|
- set the blur to .8
|
|
|
|
*** apply the original mask to the smart filter
|
|
- OPT + DRAG
|
|
- =CMD+I= invert the mask
|
|
- apply the smart filter mostly to the background
