--------------------------------------------------------
Today I'm going to show you how to use the pen tool to cut out an object from a picture. This is the picture I will be using for this Tutorial:
In this tutorial I will show you how to separate the CRJ700 from the background in this picture.
First you need to save that picture to your computer and open it up in Photoshop like so:
Okay next, select the pen tool and zoom in to the image so that you can get a closer look at the edges of the plane.
Zoom in by: Ctrl++
You can zoom in as close as you want but I recommend zooming in by 500%
Make sure you zoom in close enough to get a good look at the edges of the aircraft.
Now, using the pen tool, Start to place anchor points around the edges of the entire Aircraft.
Work Slowly and steadily around the aircraft. Try to place Anchor points as accurately as possible.
Notice in the picture bellow how I have used less anchor points on straights and more anchor points on
curves.
Also A general rule of thumb is to try and stay at least 1 pixel within the object just to make sure that you don't get any of the background within the path.
Once you are done the whole Aircraft zoom out using: Ctrl+- so that you can see what you have done. Look to make sure there aren't any mistakes
Should you happen to find a mistake you can move an anchor point by holding Ctrl and then click and drag the anchor point into its new position.
There we go! Its all fixed.
Should you happen to find an anchor point which you think shouldn't be there all you have to do is right click on that anchor point and then click "Delete Anchor Point" from the pop-up menu.
Okay now that you are done and you have fixed all of your mistakes lets make the path you created a selection. BUT first! lets unlock the background layer just to make sure that we don't have any problems. To unlock the background layer double click on the background layer and then hit OK in the dialog box that comes up.
There! Our background layer is now unlocked and has been renamed to Layer 0 (Or whatever you named it).
Now we can make our path a selection without any problems. So, right click on any of the anchor points, on the path around the aircraft you have created, and select "Make Selection"
In the dialog box that appears make sure you check anti-aliased (so to reduce jaggies). You also might want to feather the selection. Feathering the selection basically blurs the edges so to reduce the look of jaggies. I would recommend feathering by 0.5 pixels, but that's up to you. When you are done click OK.
Our path has now been turned into a selection. As you can see the anchor points have disappeared and the path has now turned into a moving back and white line.
Now lets make a copy of our selection (Get the plane off from the background). Right Click inside the selection area and select "Layer via Copy" from the pop-up menu.
There we now have, two layers. The original image is on one layer while the plane is by itself on another layer.
To view the plane by itself just click the eye symbol beside Layer 0 (The layer with the original image on it)
And there we have it! The CRJ Is all by itself. It has been cut out from its background. Now you can Save this and copy and paste this CRJ to any background image you like. This ends Tutorial #2. Have fun!

First off, the purpose of this tutorial was to educate people on How to Cut Out Objects. I didn't make it on the pen tool in general.
Secondly when it comes to Flight Simulation, cutting out objects is useful for making composites. (If you don't know what I'm talking about you obviously haven't visited some of the flight simulation screen shot websites such as ScreenShotWorld just to name one)
Thirdly this tutorial was targeted toward "new people"
Anyway that's just what I think.

Meh, just a suggestion, curves will make it better.

(The Britsh Airways A320 in my sig was "Cut-out" using the method described in the tutorial above. Look at the result. Crisp and accurate isn't it?)

You cant easily fix mistakes with polygon selection tool as you can with the pen tool, mate.

Why?
That's the only way people are going to learn.
And it is accurate if you know how to use it.

Making curves with the pen tool, I know for me, has always been very clunky. In the end, I usually just make little tiny straight lines until I eventually click my way around the curve. Hey, it works! I used the technique with this image: http://i121.photobuc.../2009Camero.png , and while curves would work best, the tiny-straight-lines-with-the-pen-tool-around-the-bend technique seems to work almost as effectively.
Good tutorial.

Curves are the way to go lol.

Read Please. I didn't say I couldn't use curves I just said I found it too bulky and Not as easy the point to point method.

Exactly

I've been photo shopping for a couple of years now and took a course in high school on this. Again this tutorial is for "Newbies". And guess which method they decided to teach us first (And recommended us to use) back when I took that high school course? Not Curves.
Also a question I'd like to ask: How many of you have actually tried the point-to-point method on a regular basis, hmmm? Don't draw any conclusions unless you actually tried and use both methods please.

So much easier.
Meh, I respect anyone who tried to do a tutorial to help anyone, but just throwing it out there

Get ready to be schooled.

WRONG! You could not be any more wrong. The pen tool and its properties is based on the Bezier algorithm. That's why vector images are math and not just image data. Go look up the differences between vector and raster.
Second of all, if curves aren't accurate - Then I highly suggest you to go running into any car company HQ and tell their designers to stop! Because apparently the pen tool isn't accurate, yet it's used to develop car designs amongst several other things in the world!
Third of all, they, my silly little teenager buddy, curves are not fiddly. Why? They're not, you can get a closer gap between things. And if you mess up? Well, just add a point and work the kinks out. Which takes less than 30 seconds at most for anyone.

1. You prefer it that way because you learned how to use the pen tool in this manner. Which isn't how you're supposed to use the pen tool, but whatever floats your extra tiny boat. Most people like it this way because they're lazy to learn the real way and about it when they can do it right, or rather they don't want to follow steps.
2. For a couple of years, hmm? And you took a course in high school. Well done. A newbie can pick up on how to use the pen tool in 20 minutes time tops, learn something the wrong way and it'll be with you and it will become harder to change your ways.
You've been using Photoshop for 2-3 years? I've been using it since 5.0, you were still playing with toys back then! Whoever your teacher was is an idiot. Shame on him or her for even teaching students to learn this cheap method.
3. I have, no really I have. It came out choppy. The pen tool was integrated into Photoshop to create vectors and extract images with clean cut lines. A good job doesn't require you to feather the edges. A plane doesn't travel in the sky with a fuzzy halo around it.
