First of all, you need a high-quality photo. In this tutorial, I decided to create my own low-profile portrait, so I need my friends to help me take a group of high-quality photos. What you need to remind netizens here is that the depth is expressed by perspective, so the photos need to have good highlights and shadows, and at the same time, make sure that there are some hardware accessories on the model, which can contrast with the model's skin and clothes (like glasses, jewelry or straight collar). Next, we need to choose the best part from the photos taken and synthesize the material photos we need. Take the following figure as an example. I chose details such as face and glasses from different photos. At this point, it doesn't matter if you are picky. Select the required part and roughly cut out the required part. Then create a canvas with a black background in Photoshop, and put the selected part into the Photoshop canvas as a separate layer element.

Second, now, we need to combine the selected parts to create the perfect material photos. Delete the unnecessary parts and put the selected parts together. Masking and blending modes are mainly used here. Here, you don't have to collage exactly according to the original picture. In fact, all you have to do is collage according to the way you like. For example, I don't like the way my eyes are placed on my ears, so I lengthen my eyes. In addition, the author also made some local modifications to the hair in the control film.

Third, now adjust the contrast, color balance and color scale of the synthesized image to create a more dynamic image. I probably shouldn't say this here, but I do often use the automatic contrast, automatic color and automatic color gradient functions in Photoshop (in the image menu). These automatic functions are quite practical, especially when you don't want to manually correct the composite image.

Fourthly, I hope that the tone of my final product is warmer than the tone of the photo, so I have done some color matching here, mainly adding a purple color filtering and mixing mode layer.

Fifth, to do this, we will enter the most time-consuming part-triangular grid. There is no shortcut here, you can only do it by hand. Why? Because your brain is better at drawing facial contours than any script or automatic tool. Of course, the author still has some experience here. Use small triangles in small places, not quadrangles-they will look bad. Be sure to stick to the triangle. If your goal is a straight nose like the author, it will be easier, and a round nose will be more complicated. Use a small brush to create a grid on the blank layer of the image. Use light colors to contrast with portraits. I prefer to use blue or green, because these two colors rarely appear on portraits' faces (unless they have tattoos on their necks).

At this point, you can pat yourself on the chest, because you have made a lot of efforts (but not all). Now it's time to correct the wrong triangle. Here you need to focus on the grid, so hide the image first, and then look for where you forgot to create the triangular grid. Once the triangular mesh is improved, change its color to white to make it stand in sharp contrast with the black background, and then save it as jpg. Then open Illustrator.

Drag your grid to the artboard, lock it, and then draw a vector grid with a pen. Here I suggest using contrasting colors (I'm used to bright purple). Of course, this step is also a time-consuming step, so the author specially turned on his favorite music and prepared coffee, thus alleviating the irritability caused by this time-consuming step. Here, the author gives you some tips: you don't need to close the triangle, just mark three points with a pen. This may sound silly, but it can really save you a lot of time, especially when you need to create hundreds of triangles.

In fact, it doesn't need to be particularly precise, because in the next few steps, you will use a technology to connect them together.

The workload is really heavy, but you must be confident that you can do it well. To do this, you can have a rest first, but you must remember to save it. Remember! Remember.

Ten, here, the author will teach you the skills mentioned in the eighth step, which can make all points completely aligned in the right position. This is a simple procedure, but you need to repeat the number of triangles in your picture. Use the direct selection tool to select a set of points that should be in the same position.

Eleven, open the alignment panel, click on the horizontal center alignment anchor.

12. Then click on the vertical center alignment, and all your anchor points will appear in the same place.

If necessary, now move the surrounding anchor points to correct their positions. Then repeat step 10- 12 for all points.

14. Hide the grid you created in Photoshop here, and check your grid again for missing triangles (I always forget at least 10 triangles every time). The best way is to select all vectors (command /Ctrl+A) and then switch to fill and stroke (Shift+x). If you find a triangle missing, go back to fill and stroke (press Shift+x again), add a triangle, and check again. When you have completed a complete grid, you can move on to the next step.

Fifteen, put your picture material on a layer, and put the layer under the vector grid at the same time, and then align the two perfectly. So you can choose the right color for your image. Remember to lock the picture material layer.

Sixteen, this step is the most interesting step-adding color. Select each triangle in turn, use the eyedropper tool (I), and then select the color in the middle of each triangle to fill it.

The final effect:
