Step 1) Using the circular marquee tool, make a simple circle using any color you like. We will think red for this example.
Step 2 - Give the circle an inner-glow layer effect by changing the glow color to black and changing the blend mode to multiply. Using an inner shadow can result in an angular deflection which is why we use the inner glow method for uniformity.
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. Now press Ctrl/Cmd+T to transform the white gradient. Drag the handles to bring it upwards halfway through, and drag it in a bit in from the top and sides. Create a merge composite layer: Hide the background - Create a new blank layer on top and then Press Alt+Ctrl+Shift+E (Option+Cmd+Shift+E on Mac) to create a merged layer on top.
Step 5. take the merged layer and create a circular selection above. the circle should be much larger than the original circle. Again use your eyes to tell you what seems right, then copy the section and paste it in to a new layer. This creates the top portion of the orb. Place it again in the proper exact position.
Step 6 - For the base of the orb,create an elliptical shape fitting in to the lower half of the circle within a new layer. Duplicate this layer while reducing the size marginally.
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. Duplicate this layer too and bring the duplicate upwards, as shown. Now place the white small portion up above the actual gradiated layer. Place it as shown in fig.8. Link both layers and reduce their size by a bit, so that the outer gradiated ellipse is just a bit within the red circle.
Step 9 - Choose the duplicated gradient layer, giving it a slightly different gradient of greys and whites. Bring the duplicated gradient layer down, positioning it under both of the other layers. Move it to where it is seen from both sides as it is the rim of the orb.
Step 10 -Erase the parts 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. 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 middle part of the orb.
Step 11) Let's create the glass portion. Make a circle of the same size of the orb in any color and place it behind the other layers.
Step 12. As with the initial outer orb, give it the same kind of innerglow effect, and now bring it forward so 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 -Create a white gradient reflection like in the red circle, in a new layer above the glass layer, to have a more realistic lighting effect. You will have to adjust the settings as needed 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. Finally give a very slight drop shadow to the upper portion of the red orb, just to attain more realism. Secondly the lower portion seems off. SO create a new layer above the red lower orb portion. Then select the radial gradient tool, and select the white to nothing option. Now drag from somewhere above the red to a little bit in. Erase portions that arent contained within the red portion. Check Fig.16. to see the effect.
Now your glass ball is done. Any items can be showcased inside there now, just make sure they have a good reflection added on. This effect will give the base a shiny and realistic look.
