When creating either a horror opening title sequence or a horror trailer, it is vital to make it as realistic and as believable as possible and this is done not only through the acting but through the smaller details also. When watching a horror film, the common theme of blood often occurs and it is therefore important that it is of the correct constancy and look in relative terms to the sub genre of horror that is being produced. "Possessed Productions Blood Workshop" shows the process in which multiple types of both edible and inedible bloods are made and how the look when in a re-enacted situation.
The first blood in which the video shows is chocolate blood, this blood is made by blending 1/2 of a cup of water with 1 tablespoon of powdered cocoa and then adding 4 tablespoons of Golden syrup and 1 teaspoon of red food colouring. This particular form of blood is thin in consistency and of a deep red colour, this therefore means that it would be good for knife wounds because the initial blood spurts would be of a thin consistency.
The Next blood type shown within "Possessed Productions Blood Workshop" is peanut butter blood, this particular type of blood is created by using 1 part peanut butter to 1 part golden syrup and then adding single drops of red food colouring until the mixture is of a colour in which the individual is aiming for. This blood is very thick in consistency and it is also of a dark red colour, this therefore suggests that this particular type of blood should be used for scabbing on such creatures as zombies as well as any form of ageing blood upon a dead body or a distantly hurt victim.
The third blood type used within the above video is gravy blood, this blood type is made by adding gravy granules to hot water and mixing as you would when making normal gravy. You then add red food colouring to the mixture to form a deep red but thick form of blood. This blood type forms a thick looking and dark in colour suggesting that it would look good on a dead body or as a slow healing scab or wound.
Next is mint blood, this particular type of blood is made by mixing 5 tablespoons with 1/3 of a cup of water together, then adding 2/3 of a cup of corn syrup. Once you have a thick, gloopy consistency of corn mixture add two or three teaspoons of red food colouring, this amount will increase in proportion to the darkness of blood in which you are after. Also add green food colouring to take away the harsh look of the red, this will make the blood look more consistent with that found on the body, when the blood is fresh from the heart it is light in colour and when it has been exposed to the environment, it is a red or brown colour. The mint blood has a consistency which allows for change depending upon the circumstance in which you are filming. This form of blood would be useful for zombie flesh or even blood spurts directly form the body, this form of blood could look like real and "live" blood meaning you can put it into a syringe and spurt it as a stab wound.
After mint blood comes coffee blood, this form of blood is created by boiling water in a kettle or upon a stove, you then sieve in the flour making sure the lumps that form are of a size similar to blood clots. Add the red food colouring to the mixture and stir, the volume of each ingredient is unimportant as it depends upon how much blood you need. This particular type of blood would be very good for large scale blood spills as well as clotting blood around a victim. The lumps within the blood will look like small clots which would occur after death or blood spillage.
Next is cheap and easy blood, this is made by mixing own brand washing detergent and red food colouring. The cheaper the washing detergent, the better the blood looks as it liquid bubbles less than it would otherwise. It is important to make this type of blood in large volumes because it looks more realistic in mass, using this blood for stab scenes or torture scenes allows for a realistic looking blood to convince the audience that the scene is real.
