Photoshop - Destructive vs Constructive Editing (Quick Masks)

Uploaded by Modelitup on 08.10.2012

Hi this is Matt from
in this tutorial we'll be going over Destructive vs Constructive Editing
I'm gonna grab some stock images from stock.xchange ...
... if you'd like to follow along we've got the urls right here.
Now I'm going to grab the "Apple Tree Branch" Background (Layer) Double click on it..
... and im going to change that to a layer that I can edit.
Select it (the layer), press "Edit" > "Copy"
... go over to the macaw-and-cockatoos file
"Edit" > "Paste" and I'm going to make this a smart layer by Pressing
"Layer" > "Smart Objects" > "Convert to Smart Object".
"Edit" > "Free Transform" and I'm going to zoom out...

... and it will lock the Height and the Width.
Press the Checkmark, and I'm going to double click this "Background" (layer) and type in "Birds"
Drag it above the "Layer 1" and I'm going to change (rename) the "Layer 1" to "Backgrounds".
And I'm going to hide the layer "Birds", now actually ...
I don't I dont need to hide the layer birds I'll duplicate it to show you the difference.
So what we're going to do is show you the difference between the original..
... and Destructive vs Constructived Editing, Destructive Editing would be if we grab the "Background" (layer)...
and select it normally with the "Quick Selection Tool" it will work fairly well because we have hard surfaces...
if we want to un-select we hold the "alt" key on our keyboard, just drag, and we're going to save this...
selection ("Select" > "Save Selections...") so we can show you the example later, so name it "Background".
Now if we just delete this is where its Destructive Editing..
.. once we edit it we rely on our "Step Backward" now if we use "undo's" or "Step Backward" we have a limited amount
... and thats a very destructive way of working because you have to go back and forth just to get that fix.
so for example, we need these feathers, or we need a part of the bird over here sometime it removes in this area
yeah see half of his face is gone.
so once you've deleted it's pretty much gone and you can't get it back (historys limited).
Now Constructive Editing allows you to do it in a way that's very simple. So lets just show the "birds copy".
We're going to go to "Select" > "Load Selection" and we're going to choose "Background" (Press Okay).
Press "Select" > "Inverse", and then click on "Quick Mask" (Icon).
Now what thats done is its turned our background into a black color, and our foreground is the white color.
White is visible, black is invisible. If we click over here it shows us our RGB qualities ...
... and if we click on this mask, it shows us only the properties on our Layer Mask.
So if I click on this one I can zoom over to this area, choose our Brush Tool and pressing "X"
... it will switch between our two swatch colors, or you could always choose this button.
If I choose White its visible so I can start painting white as long as I've clicked on here ...
... it will start to show the original part of the image.
That way we don't have to go back and forth to edit things, we just have to press "x" ...
... and it will switch back and forth between showing it and hiding it.
So if we go over to this area of the face and we have it on white ...
... and we paint on it, its bringing the entire face back, as long as our opacity as fairly 100% ...
... or depending upon our adjustment it's what we want, it will be acurate depending on that.
So if its still too hard (edged brush) we still have the undos. But we have full control of all of the image now.
So this is a quick way of editing and constructively adjusting your image without destroying things.
So for here we can still use our Marquee tools or our lasoo tools.
This one I believe is the Polygonal (Laso Tool)
So we can just click and fix things by clicking on the mask, pressing "Alt" + "Backspace", as long as its black (color) it's going to hide it.
So we have full control over the image.
Now the reason we chose Smart Image or I'm sorry a "Smart Layer" or "Smart Object"
... if we click okay we have the Height and Width ("Image" > "Image Size") of the original image.
So "3008" by "2000", if I go "Image" > "Auto Color" and then click this "x" ..
... and press "yes" it does edit this image, but it the image is much smaller than this one.
So we have the full quality stored within this smart object. If its scaled below that quality, and we press okay.
It will be okay to scale it back up.
It won't pixelate just like a Destructive Method would.
It would pixelated because it's changed its original format once you've squished it.
Now with the new versions of photoshop it might not be a problem...
... but if your using older verisons you will run into those issues.
And these are the final steps you'll need to know how to fly!
In our next tutorial we'll be showing you how to fly, and if you have...
...a camera and a tripod we look forward teaching you how to make some crazy effects.
