If you have a faintest urge to learn Photoshop, you need to visit Lind.com and know a person Deke McClelland who is the best pro to teach you a thing or two in Photoshop. Even if you are working with Photoshop for quite some time, Deke McClelland will give you a tip or two which will help you immensely.

This video is on Photoshop CS4 smart objects. This will teach you how to edit, re purpose and crop your compositions without affecting a single pixel even in masks and practical advantages of non destructive transformations, which allows any object to be manipulated in any way maintaining its original pixel information.

Once you access all of Lind.com completely for free, stay tuned to the end, to the podcasts to find out how.

Welcome to the Lind.com video training podcast for Friday November 13, 2009. This is episode 188. This week learn to make non destructive transformations from smart objects and set of pixels. Video from Photoshop CS4: Smart objects with Deke McClelland.

Hi Garrick Chow here and this is the Lind.com video training podcast bringing you incredibly useful tips and tricks from our latest releases. And today we have the coup from the prolific Deke McClelland’s newest title Photoshop CS4 smart objects. In this tutorial Deke explores the creation and use of smart objects, one of the most technically demanding tools in Photoshop, but not to worry, Deke runs through the four primary processes of smart objects and focuses especially on one of the most practical advantages non destructive transformations, which allows any object to be manipulated in any way also maintaining it’s original pixel information. This tutorial is a must see for any Photoshop user who want to know how to edit, re purpose and crop their compositions without affecting a single pixel even in masks.

In the following clip from Photoshop CS4: Smart objects Deke explains the rewards of non destructive transformations.

I’m going to see my progresses two models down PST found inside the old one how they work folder and we have one version of the model rendered in pixels here and she’s been scaled down to 10% and then back up to 720%. The result is a 72% scaling. However because I applied it in two passes, we have a destructive modification. Now, we’ve got a smart object and an independent layer, the pixel are protected. We’re going to apply those exact, same transformations as before. And here’s how.

I make sure that my smart object layer is selected. Then I go on to the Edit menu and I’ll choose the Free Transform command or I could press Control T, Command T on the Mac and I can shift drag on of those corner handles in order to scale the image proportionally but instead just to make sure that we’re applying the exact, same modifications as before, I’m going to go up to my Options bar, turn on the Link icon and I’m going to change either the width or height value, doesn’t matter which one to 10% and then I’ll go ahead and except that numerical modification by pressing the Enter key or the Return key on the Mac and I’ll press Enter or Return again to escape the Free Transform Mode and apply the transformation.

And now zoom in on this tiny little version of the image. This is the exact same way she would look if I scale the pixels down to 10% because when you apply a single pass, a free transform; it’s no different whether you’ve applied the transformations to a pixel based image or a smart object layer. So we’re going to get the same result so far.

However, Photoshop is now aware of the original size of the image, so because the pixels are protected inside this smart object container all of the pixels are still there. That’s the difference. It’s been rendered on the fly at 10% so on the fly we’re just saying one out of every 100 pixels. One out of every ten horizontally, One out of every ten vertically. However, they are all there in the background and that makes a terrific difference.

Let’s now say that I press Control T or Command T again in order to once again invoke that free transform command. This time I go up to the Options bar and notice it’s not telling me width a 100%, height a 100% which is what it would tell me if I was working with pixels because that’s all know. It would now know that it got its dickey little thing that’s working with and it’s 100% of its size because you haven’t done anything to it yet.

In this case though it knows that its 10% of its former size because it still has all of those pixels working in the background. Now go ahead and turn on the Link icon. I could change its value to 720%. But if I do that, its going to look super dark and sharp, the reason being because it’s working from the 100% pixels. So its not taking the 10% pixels and making them 720% larger. It’s working from the original pixels.

So what we need to do is the math here. We need to take 720 divided by 10 that’s 72%. Notice that if I change the value to 72% we a get much more reasonably sized image here and I’ll go ahead and press the Enter key couple of times or a Return key a couple of times on the Mac in order to invoke that modification.

Now let’s zoom out a little bit so that we can see these images side by side. I’ll move her over so that she’s just sort of slightly cutting into the other one there. That is so the good one cutting into the bad one a little bit. I want to be able to see both of them. They’re exactly the same size.

So the up shot of this modification here was 10 times seven hundred twenty is seventy two percent. The problem is that the transformations did not concatenate and that wont concatenate means that Photoshop goes ahead and reconciles the math and figures out the final transformation value. That did not happen when we applied free transform in two separate passes to pixels but because we applied free transform still in two separate passes but to a smart object container here.

Photoshop went ahead and did the math and concatenated the values and figured out that 10% and then 720%, that is making the image larger will come out to 72% and as a result if I zoom in on this image also press Shift Tab to get rid of my palls, you can see that she looks great when transformed as a smart object and she looks terrible over here in the right hand side of the screen when rendered out in pixels. And that is the difference between a non destructive transformation and a destructive transformation here inside Photoshop.
