How to Draw Cuts and Wounds Paint Tool Sai

Picture skin damage

Introduction

Therein instructor you will learn some tips and tricks for painting a duad of types of damage to skin. We will be looking specifically at harmful, bullet wounds, and different types of scarring. I am using the latest version of Photoshop, but you should be able to apply these methods and techniques in any other digital painting software. IT is also all important that you have a drawing tablet of some kind, I am using a Wacom tablet.

Please note that I am not using any custom brushes in this instructor and that everything shown here should be possible with a basic chalk and airbrush which you should have available to you in whatsoever digital painting software.

Let's paint some damage

Bruises

Whether you are creating textures for zombies or illustrating a character who is injured, bruises are useful to understand because they will almost believable appear anywhere where damage to shin or flesh has occurred, which is sure enough something we run across a lot of in digital art.

The first matter to note nigh bruising is that they are made up of many different colors. The people of colour of a spit signifies its age and can tell you a dole out about what caused the bruising to occur in the first place.

A spit is always ready-made up of many disparate colors

Brush

To create this bruise I misused peerless of Photoshop's bequest Chalk brushes with roughly Scattering applied in the brush settings. You can believably use some textural copse to accomplish the same look. The main thing is to use a sweep that's not too smooth as bruises are caused away capillaries bursting underneath the skin, and because at that place are likely to be spaces between the capillaries that have flare-up, we deficiency to create a dappled or textured look.

Life cps of a bruise

The colors that occur in a bruise generally signify various stages of healing and can assistance to illustrate the size and severity of the initial injury that caused the bruise. After the initial injury occurs the contuse will generally appear as a deep pink as this is where the bleeding will pop. Government note that the intensity of the color will disappearance somewhat at the edges of the bruise As the bleeding thins away from the initial point of injury.

Every bit time goes by the colouring will change from pink to a deep purple or bluish color (due to hemoglobin). While healing, the body starts breakage down the haemoglobin. The interval of amino acids and iron in the Hb is what causes the bruise to alter color from purple to brown-green. The final stage in the remedial process results in the bruise turning chicken, and is caused by the formation of an enzyme called Hematoidin. This eventually fades formerly the spit is fully healed.

Often you bequeath see a bruise containing all of these colours as different areas of the bruise Crataegus laevigata be at different stages of the healing process. This is usually to do with the severity of the injury at that point. So if you can imagine beingness hit on the arm with a rock, the point of contact will be where the most damage occurred, and that steer will likely have suffered the most bleeding and therefore take the longest to heal, patc the outside areas volition heal up much quicker. Because of this, it's same common for a bruise to be purple at the marrow and then yellowish happening the outside.

You can use this to assist describe the typecast of action that caused the bruising. For instance, bruising from strangulation might show a hand print in purple approximately the victim's neck with light forceful towards the outside, and so happening.

Bullet wounds

Most bullet wounds will have got some an entry item and, if the bullet passed through its victim, they will as wel have an leave point. These wounds are quite an different from one another, and you can use this to help with the narrative you are trying to convey, such as if your eccentric was shot spell running away.

Bullet wounds will wait unusual depending on whether they are entry or exit wounds

Brush

For this I have again used i of Photoshop's legacy Chalk brushes with some Scattering applied in the settings. I am also exploitation a standard airbrush without any additional settings practical.

Bullet entry wound

Bullet introduction wounds tend to be precise clean with minimal bleeding as the bullet (obviously depending on the bullet, but generally) pretty practically stops the bleeding while it's passing direct. You might flat find that some bullet wounds don't leech at all unless the slug passes right field through and leaves the organic structure. These wounds will tend to live very dark at the center where the blood is thickest and pooling, and will be quite light close to the edges. You will probably also see some swelling around the outdoors, and probably several bruising if the injury isn't too smart.

Bullet exit wound

Bullet exit wounds, unlike incoming wounds, can be quite messy. The rind and flesh will appear torn around the edges and the wounds might look quite severe. Exit wounds volition often have tumid skin flaps that protrude from the wound from where the bullet forced its way out, and these English hawthorn be accompanied by tears that can be either small or very large. You leave also often see blood splatters around an exit wound from where the bullet pushed through.

Scars

There are several different types of scars but the three most prominent which you are likely to use in drawings and textures are; fine-line scars, raised scars such as Keloids and Hypertrophic scars, and sunken/pitted and Atrophic scars. Each is quite unequaled and different in appearance and can be used to add a greater sentience of astuteness to whatever character because scars tell apart a story of things that have happened to us in the past.

Scar texture

To achieve a generic texture that simulates scar tissue, I am only using repeated angular lines of various colors. Even the specular highlights on the scars use the same angular lines. As with the previous images, I am victimisation a standard Glass brush with some Scattering applied here.

Raised scars

Raised scars are adorned above the skin and occur when our bodies produce too much collagen at the land site of a combat injury, causation an excess of weave. This work up seat continue for several months or in some cases tied years!  In Hypertrophic scars this tissue stays within the confines of the wound, but with Cheloid scars the tissue overgrowth will extend beyond the boundary of the initial wound.

Fine-demarcation scars

These are the most democratic type of scrape and are generally caused by common cuts or minor wounds. Fine-communication channel scars will tend to be matt and lav come along rather light-colored or silverish. As these scars can atomic number 4 quite pale they might be more noticeable on darker skin tones because scar tissue does not tan or dim over time. When painting these scars you can color pick from the surrounding skin surface area and bring off some of those colors back into the scar to help blend it with the skin and prevent information technology from sounding "stuck along."

Sunken/pitted and Atrophic scars

These scars are most commonly found on the face and tend to be Eastern Samoa a result of acne or chickenpox. They will in general appear every bit some pits in the skin, big the skin a bumpy sort of surface texture. These types of scars lean not to be shiny like the other types and will often true fair assume the same coloring material Eastern Samoa the surrounding bark area.

To achieve the look of cellular or atrophic scars you commode simply use a slightly darker shade of complexion to create the pits and so fade these back into the surrounding scrape past using a textural brush with the surrounding scramble color. Remember these incline not to be shiny or colored like other scars.
