Now create a big bubble, where we will place our model. There is nothing to search and download, I'll show you how to do it yourself. First, we need a new document (Cmd/Ctrl + N or File > New) 600 pixels wide and 600 pixels height, resolution 300 Pixels/Inch, Background color: Other (black). Merge all model layers into one (Cmd/Ctrl + E).
Go to Filter > Render > Lens Flare... Set Lens Type: 105mm Prime, Brightness: 100%. Position highlight in box so that its edges have been cut off, and all parts of flare not be the light source and click OK.
Go to Filter > Distort > Polar Coordinates... Set "Polar to Rectangular" and OK. Rotate image on 180 degrees (Image > Image Rotation > 180 degrees).
Again add a filter "Polar Coordinates" but in this time set "Rectangular to Polar" and your bubble done! It remains only to cut it. Use Elliptical Marquee Tool (M) and hold Cmd/Ctrl + Opt/Alt to create proportional circle from the center of the image. Be careful and attentive. Make sure that you have circled the entire bubble and it did not get excess. To make it easier to use - right click > Transform Selection. Take Move Tool (V) and move bubble into document with photo manipulation.
Now continue in the working document. Change Blending Mode to "Screen". Place layer with bubble above model's layer and resize it with Free Transform tool (Ctrl/Cmd+T or Edit > Free Transform) slightly larger than model.
Add some texture on bubble. Load in Photoshop "Hexagons textures" brushes and on a new layer with Brush Tool (B) (Size: 300 - 500px, Opacity: 70-100%) draw texture which you like (I use "Sampled Brush ...â€ 16 and 17). Use white color and clip layer with texture on bubble (Cmd/Ctrl + Opt/Alt + G).
Now, create a volume for the texture, because the flat it cannot be. Hold Cmd/Ctrl and click on bubble thumbnail and return to the texture layer. Go to Filter > Distort > Spherize... and set Amount: 100%. Here is the volume that makes realistic bubble.
So, part of the central sphere is ready, but now I am focusing on the creation of small spheres with cyborgs to revitalize a little picture and vary background. I will be able to create a more harmonious other elements (wires from the central sphere, bubbles, etc.). First group all the layers of the central sphere (Cmd/Ctrl + G) and duplicate it (Cmd/Ctrl + J). Duplicated group merge in a single layer (Cmd/Ctrl + E).
Use Move Tool (V) + Opt/Alt to make more copies of sphere. You need a depth of field, so first start filling picture with several larger spheres. Use Free Transform tool (Ctrl/Cmd+T or Edit > Free Transform) to change the size and rotate sphere. Rotate the sphere considering that bright flare should be towards the central sphere. Do not worry that the spheres have become dark, just change the Blending Mode to "Screen". When place spheres in the right places, merge these layers into one by converted layer into Smart Object (right click on layer > Convert to Smart Object).
Duplicate resulting layer (Cmd/Ctrl + J) and reduce it to get small spheres. Repeat the technique in the previous paragraph, only taking into account that you have a lot of spheres and that they need not much overlapped one upon the other.
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%.
