Turn any photo into a dot grid artwork with these Photoshop actions. You'll get great results with dots that change size. They get larger in brighter areas and smaller in darker areas. Free download available.
Step 13
Therefore, the image looks a bit dark, but add to it adjustment layer "Curves" (Layer > New Adjustment Layer > Curves... or click on Adjustment Layer icon on Layer panel). Set values to each point as shown in the image below. This layer, we lighten the image, while maintaining its texture.
Set this layer as Clipping mask (click on Curves layer RMB and select "Create Clipping Mask" or use Option/Alt+ Cmd/Ctrl + G or click on the icon of a square with an arrow, as shown in the previous image).
Step 14
Now, proceed to next layer with DNA. For it, set a Blending mode "Darker Color". Similar to Blending mode "Darken" (Compares two source values and replaces light pixels values of the dark), except that it works on all layers at once, instead of one. When you mix the two layers will remain visible only dark pixels. In our case, this layer will be the basis for the centers in every sphere of DNA.
Step 15
Now, for the remaining two layers DNA, set a Blending mode "Luminosity" and Opacity: 50%. This Blending mode opposed to "Color". Combines Luminance (light) of the upper layer and Hue (color) and Saturation (color variations) of the lower layer. It turns out that glow, which we did in the previous two layers amplify and create one almost transparent distance between the center of the molecule and the glow edge. Because blue background and the previous layer (which just increased the dark areas in the center), the center of our molecules have become smoother and more expressed.
Step 16
Now we are a bit remove the previous effect. Because a strong contrast of center and edge does not look of realistic. Besides it is necessary to reduce the center. To do this I use adjustment layer "Hue/Saturation" (Layer > New Adjustment Layer > Hue/Saturation...). This layer should be above two "Luminosity" layers of DNA and set Opacity: 25%. Set the settings like shown in the image below.
Step 17
Begin to create texture on DNA and work on them of realistic. The first thing we will revise a little brightness, contrast of the entire molecule and dark portions of DNA. Add the first adjustment layer "Brightness/Contrast" (Layer > New Adjustment Layer > Brightness/Contrast.... Increase brightness and reduce the contrast as shown in the image below. Be sure to apply this layer as Clipping mask (Option/Alt+ Cmd/Ctrl + G).
Step 18
Now you can apply a texture. We do it by means of Photoshop. Create a new layer (Cmd/Ctrl+ Shift+ N), press D then X to set Background color on black and use Cmd/Ctrl + Del to fill it black color.

no
It's a good thing that some images come with what's written... Too many mistakes from picture to writting...
Even the size of the doc is wrongly written..... That's just poorly written Tut....
some pic is not found, please repair it, thank you!
Nice one
What is RMB?
This is the right mouse button.
thx!
I'd like to learn more same techniques)
