Which type of analysis is performed on documents as evidence?

The analysis performed on documents as evidence is appropriately identified as handwriting analysis and photography enhancement. This type of analysis is crucial in forensic science, particularly when dealing with documents that may contain signatures, handwritten notes, or other textual elements that require verification or examination.

Handwriting analysis involves comparing the writing on a document to known samples from a suspect or individual to determine authenticity or to identify the writer. This process requires understanding various aspects of handwriting, including style, slant, pressure, and formation of letters.

Photography enhancement plays a significant role in document analysis as well. Forensic experts often utilize advanced techniques to improve the clarity of existing documents that may have been altered, damaged, or are otherwise difficult to interpret. Enhancing photographic images can reveal previously obscured information, such as erased markings, watermarks, or faint text.

The other types of analysis listed—blood analysis, fingerprinting, and physical analysis of textures—are more relevant to different types of evidence (e.g., biological fluids, latent prints, or surface characteristics) and do not specifically pertain to documents. Therefore, the correct choice effectively represents the specialized analytical techniques used in the context of document examination within the forensic field.
