1. Create a new image in Photoshop , use the Ellipse tool in the shape tool, and draw a ring, that is, a large circle minus a small circle in the middle, as shown below. Note that it must be drawn in vector format. A tutorial on path drawing can be found in Chapter #12.
2. Copy the ring path multiple times, move it to any position, and specify different transformations respectively. After the transformation of each group of rings is completed, they should be combined to avoid the operation method affecting other rings. The effect is as shown below.
-
The layers palette is as shown below.
-
Execute [Layer_Rasterize_Shape] on the vector shape layer, and then use [Filter_Stylize_Find Edge] to get the effect as shown below.
3. Use [Filter_Stylize_Highlight] and [Filter_Blur_Radial Blur] in sequence. The settings are as shown in the 2 pictures below.
-
4. Use [Image_Adjust_Color Balance] [CTRL_B] or [Image_Adjust_Hue Saturation] [CTRL_U] to color the grayscale image.
5. Temporarily hide the ring layer. Use the default color [D] and use [Filter_Rendering_Clouds] on the background layer to get an effect similar to the picture below.
Then use [Filter_Blur_Radial Blur] and [Filter_Sharpen_USM Sharpen] on it, as shown below.
6. Colorize the background layer using Color Balance or Hue Saturation to color grayscale images. The effect is as shown below.
Summary: Using Photoshop ’s highlight filter to create a three-dimensional effect is a good way, but it is only suitable for smaller areas. If used in a large area, the three-dimensional effect will not be obvious. That's why circles are turned into lines. The creation of the background is the usual cloud processing technique. Use Radial Blur to create a radial feel, then sharpen it to add a sense of line. When colorizing grayscale images, it is more convenient to use the color balance command because the adjustments are more delicate, and you can create the effect of overexposure (that is, merging highlights) by turning on the "Maintain Brightness" option. Such is the case with the clouds in the background. But when adjusting the ring, I turned off this option to avoid overexposure of the ring.
