PS teaches you to create a radial background that highlights the focus

When you want to highlight something, in the picture we generally agree with the role of radiation background, and the homemade background seems to be a tedious task, put in PS, a few filters can be easily solved. Well, open your PS and let's take a look at this wonderful process together.

  One, dark-tuned beam

Step 01

Open PS and create a new 1000px-high 800px-wide file. Fills the background with a dark color. Why is it dark? Because we're going to do a radial beam, the beam is always glowing in the dark. Here, I fill the background with a purple radial gradient.

Step 02

Then, let's start making radial beams. Yes, I'm doing the same thing here, but I'm not trying to be a star, but to pave the way for the next step.

Add a new layer and fill it with solid black. Then go to filter > Noise > Add Noise. The noise panel is set to 30%, Gaussian blur, and a single color check. Rename the new layer to "noise".

Step 03

At this point, continue to select the noise layer, into the "Image > Adjustment > Levels", to open our color order, using the slider of the color scale, reduce the number of noise. The parameters here are determined according to your needs, and if you want the beam to be denser, keep the noise a little more.

Step 04

The rest of the noise is our beam "origin", a lot of people come here do not understand what is going on, is not a good light beam? How does the dotted background here turn into a line shape? or replace it with the idea that when a point is running at a high speed, its trajectory becomes straight. So let's try a motion blur filter that's related to the trend. Let's go to "Filter > Blur > Motion blur", in this case you have to adjust the parameter to the maximum, the angle is 90 degrees, so that the point shape becomes a strip. When you come across anything that you want to convert a point to a line, don't forget to blur the filter.

Step 05

It has become a strip, how to change from a strip to a divergence? This has to think about the principle of a filter-polar coordinates. Polar coordinates are in itself a mathematical formula invented by Newton, which provides an algorithm for geometry. Here is the use of this low-level algorithm to deal with graphics. To put it simply, the only part that we need to understand is that the polar coordinates filter is related to the circle, and you can probably understand some of the appearances of this principle by the name of the Earth's "Poles". In particular, divergent images are largely inseparable from this filter.

OK, back to the point, let's go to "Filter > Twist > Polar coordinates", the polar panel parameters have only two options, select from plane coordinates to polar coordinates.

Step 06

The divergent beam is already there, but it's far from what we want to be. Don't worry, we'll change the blending mode of the layer, changing the blending mode of the noise layer to "color filter". At this point, the black part is absorbed by the lower layer and becomes a gradual emission beam.

Step 07

If we still feel that the beam is not strong enough, then we can duplicate the noise layer and then blur the layer Gauss by 3 pixels. Keep the blending mode of filter color unchanged.

At this time our background picture effect is finished.

  Second, flat beam

Another case is a flat beam, the so-called flat beam is a drawing of the light beam, usually in a pure color block, almost no other modification. The beam is made in a simpler way, with a few vertical rectangles drawn first. The vertical bar is arranged according to your own ideas. I am here to design the 2016 color: Pink crystal and quiet blue.

Here's what you need to be aware of:

1, the rectangular bar is a grid, the graphics tool to draw the vector graphics must be converted.

2. The rectangular bar is larger than the entire canvas and extends to the canvas extension. The polar coordinates filter changes the edges of the graph, so we have to "hide" the edges in order for the entire divergent beam to fill the background.

All stripes are merged into one layer, and the polar coordinates filter is performed so that our radial flat beam is one-step.
