You have two layers – with large and small spheres. Make sure that the layer with small spheres was under a layer with big spheres and convert both layers into Smart Object. Go to Filter > Blur > Gaussian Blur… Make Radius: 10px. On filter mask remove part of blur to create depth of field. Use Brush Tool (B) with settings – Form: Soft Round brush, Size: 200px, Opacity: 30%.
So we added some detail to the background, and it’s time to add a little color. All of the following actions in this step will be on a new layer, so do not forget about it. Return to group “Background” and with large soft round brush (Size: 600px, Opacity: 30%, Color: #00aeef), made some great spots in the middle of the image. Set layer Opacity: 50%. Create two large spots on the sides of the image, using the color #406618, brush Size: 1300px.
Use brush with: Size: 2000, Opacity: 100%, Color: #fff200 and make lights in the middle of the bottom of the image. Layer Blending Mode “Difference” and Opacity: 70%. On the second layer use a same color but with smaller brush size: 1200px. Layer Blending Mode “Overlay” and Opacity: 32%.
Add the main source of light. Brush Size: 1500, Opacity: 100%, Color: white. Draw a light slightly above the central sphere. Layer Opacity: 40%. Select central sphere (hold Cmd/Ctrl and click on sphere thumbnail) and create a spot in in the lower part of the sphere. Use color – #fff468 and decrease layer opacity to 15%.
In this step work with background complete and we do not get back to that. This is my result. Tints may be different. You can add purple or cool blue tint. All on your taste! I made such a structure layers, because later, when I add color effects, colors mix and give a very beautiful shades.
Let’s go back to our model and add some effects on the sphere and create a sinister wire :). First, add a bit of texture to a spheres with cyborgs. Load in Photoshop “Z-DESIGN Tech Brush Set v6”. It is entirely your choice, what brushes to use (I use them all). Select sphere (Cmd/Ctrl + click on layer thumbnail) and create a new layer (as clipping mask). Draw a hologram on sphere, using white color. Try not to place circles clearly at the center of the sphere. Arrange them on the edges and you will get a much better result.
Squeeze circles by using a filter “Spherize” (Filter > Distort > Spherize…). Set Amount: 100% and OK. I’m a little decrease layer opacity to 60%. To deselect use Cmd/Ctrl + D or Select > Deselect. So you got a nice futuristic texture on the sphere. To make a hologram more natural, add style “Outer Glow” (double-click on layer) and set the settings like shown in image below.
Now repeat the same with the rest of the small spheres. To the hologram on small spheres cannot add style. Also reduce the impact on the spheres by decrease layer opacity to 85% and use a layer mask to decrease the effect on the bright areas. Also I grouped layers with the spheres in one group “Other androids”.
I decided to add the final piece to the central sphere. I wanted to create the effect of an update sphere. For this I use a brush “Sampled Brush 27” (Size: 150 – 30px, Opacity: 50%) with a bit specific settings. Go to Brush control tab (F5) and set – Spacing: 70% to turn down the density of the brush. There, in tab “Shape Dynamics” set Size Jitter: 100% and Angle Jitter: 40% (to each new piece had a different size and angle).
