At major crime scenes impressions should be photographed before they are casted. Photography is done first because casting the impression will destroy the original impression and eliminate the ability to photograph the impression afterward.

Photographing the evidence: Photographs should be taken directly at right angles, eliminating probable distance distortions for clear visualization and each part of evidence should be photographed with scale to signify size and without scale to show relationship with overall scene.

To accomplish this, all crime scene photography consists of three basic types of photographs: overall, mid-range, and close-up.

They are most useful in supplying significant bits and pieces with exact measurement of the site and evidence where the crime has occurred. The purpose of crime scene photography is to provide a true and accurate record of the crime scene and physical evidence present by recording the original scene and related areas.

A crime scene diagram visually documents the setting of a crime as it appeared when it was discovered. It typically includes a layout of the environment, location of the victim(s), blood splatter, possible items of interest like weapons, footprints, dirt, clothes along with written details and pictorial evidence.

A final sketch (Figure B) is a finished rendition of the rough sketch. They are usually prepared for courtroom presentation and often will not show all measurements and distances originally recorded on the rough sketch.

Research is where the initial ideas begin to build, so that you can envision what you are designing. Sketching helps you extract numerous ideas out quickly before you enter into a graphics editor to start designing the look and feel.

A sketch may serve a number of purposes: it might record something that the artist sees, it might record or develop an idea for later use or it might be used as a quick way of graphically demonstrating an image, idea or principle. Sketches can be made in any drawing medium.
