How does ps turn a whole egg into a crack

I will probably do it, as shown in the figure, but the effect is not very good.

When it is made, it is mainly the crack of eggshell and the gap between eggshell and egg white, which is more troublesome. Specific practices are as follows:

1: Find an egg and egg white first. You should be able to pick it up when you choose.

2: Create a new layer, buckle the egg into the new layer, use the pen tool to buckle it in half, and press ctrl+ ENTER to turn it into a selection (note that it is a natural crack). Pull it out and press ctrl+T? Deformation. The same is true for the other half until you are satisfied. Right-click next to the picture to choose the desired layer, otherwise many pictures don't know which one to choose.

3: Select the egg white in the box and copy it; Select the blank outside the eggshell with a magic wand, then edit and paste it in, or use CTRL+ALT+V and CTRL+T to adjust it until the egg white seems to flow out from the inside.

4. Adjust the edge between the two (this step is critical, and adjustment directly affects the effect). The edge of egg white should be adjusted into a dark part, and the tools used are: pen, blur tool, deepen tool, gradient and so on. See how you adjust.

If there is no shadow, make a shadow, just like putting it on the ground, which is more stereoscopic.

That's about it. It's not difficult. It's just a little troublesome.
