CROP FACTOR and Eyewitness Perspective

WHAT IS EYEWITNESS PERSPECTIVE?

INTRODUCTION

Since 1999, when I obtained my investigator’s license I have witnessed (like many of you) technology rapidly change and advance.   I was routinely upgrading camcorders and cameras, going through various recording formats from 8mm to disc, then to CFI cards, SD and micro SD, etc. 

 Through this rapid technology change to auto-tech convenience, and the advent of high quality cell phone cameras, many have forgotten or never learned a couple fundamentals of basic forensic photography.  The one aspect I want to address is developing Eyewitness Perspective, or what someone saw with their naked eye. 

 Eyewitness Perspective is when a photographer can stand in the same spot where a witness previously stood, and capture an image with the same depth of field and perspective as the witness’ naked eye view.
