A Glass Ball Tutorial Made Simple

By David Peters

Step 1. make a simple circle with your circular marquee tool. Red makes for a nice color, but you can go with anything you like.

Step 2. Give the circle a innerglow layer effect, just change the glow color to black and the blendmode to multiply. Why am I using the Inner glow instead of the inner shadow? Because inner glow doesn't have an angular deflection, and thus is easily uniform.

Step 3 - Load the selection from the circular area. Drag the linear gradient (white to transparent) downward from the top making sure it is close but not completely at the bottom in a new layer.

Step 4 - Press Ctrl/Cmd+T to change the white gradient. Drag the handles bringing them up going halfway through, and drag it just a bit inward from the top and sides. Now lets create a merge composite layer. To do this, hide the background, create a new blank layer on top and press Alt+Ctrl+Shift+E or Option+Cmd+Shift+E on Mac, creating a merged layer on top.

Step 5) Taking the merged layer, generate a circular selection above, being bigger than the original circle. Eye it to judge what looks right and copy the section and paste it in to a new layer. The top segment of the orb is created. Place it again in the exact position.

Step 6. Now to go onto the base of the orb. In a new layer create an eleptical shape that fits into the lower half of the circle. Duplicate this layer and reduce the size a little, as shown in fig.6.

Step 7. Select the larger ellipse layer and load its selection by pressing Ctrl/Cmd and clicking on the layer thumbnail. Now select the cylindrical gradient tool and going with the grey-white-grey-white-grey color combo, drag across.

Step 8) Again, duplicate this layer bringing the duplicate upward. Place the small white portion above the actual gradiated layer. Link both of these layers reducing their size some, so that the outer gradiated ellipse is just within the red circle.

Step 9. Take the duplicated gradient layer and again select it , now giving it a slightly different gradient of greys and whites. Now bring the duplicated gradient layer down. arrange it beneath both the other layers, and position as shown in fig.9. It should be a visible from both sides as it is the rim of the orb.

Step 10) Remove the areas of the orb that are not needed. Keep Ctrl/Cmd pressed and click on the layer thumbnails; first choose the big outer rim ellipse, having the gray gradient, and then Shift+Ctrl/Cmd+Click on the thumbnail of the upper top portion layer. Now the 2 ellipses will be selected, but we need to also select the bottom portion of the orb. Choosing the Rectangular marquee tool, hold down shift and drag over the bottom portion. Inverse the selection (Ctrl/Cmd+Shift+I) and delete the central part of the orb.

Step 11. Now to create the glass portion. Create a circle of the same size of the orb, any color you want. Place it behind the other layers.

Step 12) Just like the first outer orb, give it the same type of inner-glow effect, and bring it forward as to cover all but the red outer portions of the orb.

Step 13 -Make the fill amount =0 in the layer palette in order to make the layer invisible, but keeping the layer effects visible.

Step 14. As you had done with the red circle, ie, creating a white gradient reflection, create the same in a new layer above the glass layer, so as to create a more realistic lighting effect. Adjust the settings as required to make it as realistic looking as possible.

Step 15 -Select the base layers, which are the grey metal gradient layers and the white ellipse, merging them together. Press Cntrl+U to fine-tune the hue of the layer. Since it is at this point grey, click on colorize, and convert to a reddish color to keep with the color of the orb itself.

Step 16 -Lastly, make a very small drop shadow to the upper piece of the red orb, in order to create more realism. The lower portion may seem off, so create a new layer above the red lower orb portion. Select the radial gradient tool in the white to nothing option and drag from a point over the red to just a bit inward. Erase parts that are not enclosed within the red portion.

Now you have a glass ball. Any items can be displayed inside the ball now, but make sure they have a good reflection effect added on. This effect will provide the base a shiny and realistic look.
