In this tutorial I will show you how to make totally 3d logos, all in photoshop! This is one of my favorite effects, so here we go...

First off, lets make a new image with a gray background, and whatever size you want. I would make it fairly large to start.

Now, make a new layer by selecting it through the layers drop-down menu.

On this layer you are going to make the shape of your logo. So, with the color black go ahead and make whatever shape you want to make 3d. Make sure that you keep it all on the same layer.

Now, when you have finished with your shape, go to edit>transform>skew and pull the bottom two corners outward as shown below.

Next up, go to edit>transform>scale and sized down your logo by pulling only the top portion downward, as shown below.

Now we are going to add a slight bevel to our shape. So, go to filter>stylize>emboss and use the settings below.

Now, your image should look something like the one below.

Now come the easy, but effect part. While you are on the layer with your logo on it, press and hold the Ctrl & Alt button, and while holding them, hold the up arrow key. As your hold those buttons down your image will be duplicated over and over, but slightly above the original one, giving it a totally 3d look.

Your image should look like the one below.

Now that we have our shape, we are going to colorize it. So, merge all of your layers together except your bg layer by selecting merge down from the arrow on the layer pallet. Select your logo by holding the Ctrl button and selecting your layer from the layer pallet.

Now, while your image is selected, make a new layer and fill your selection with whatever color you want your logo to be. Now, change the layer style to color by selecting layer>layer style

Your image should now look like mine.

Now just change your background color to match your logo color. Now that you have your logo completed all that you have left to do is customize it to your liking. Below are a few steps that I took to make my logo look even better.

After this, I lowered the opacity of my logo layer so that it blended in a little better.

After this I adjusted the brightness and contrast by going to edit>adjust>brightness/contrast until I was satisfied with the result.

After this I selected my logo and took out my airbrush tool. After making my foreground color white, and brightened areas on my logo were the light would be hitting it more strongly.

After this you should have your logo just about 100% completed. Here is an example of the cool things that you can do with your new 3d logo.

Well there you have it, cool 3d logos without the help of a 3d program! :)
