Study Notes
Flash Diffuser
- Flash diffuser softens harsh flash light, improving photo quality.
Infrared Photography
- Infrared light is part of the electromagnetic spectrum, falling between 700-1100 nanometers, while visible light ranges from 400-700 nanometers.
Cardinal Rule #1: Fill the Frame
- Important subjects should dominate the frame to enhance focus, minimizing distracting background elements.
Cardinal Rule #2: Maximize Depth of Field
- Depth of field refers to the range in focus from foreground to background; maximizing it enhances scene clarity.
Cardinal Rule #3: Keep the Film Plane Parallel
- Ensure camera components (lens, back, sensor) are parallel to the subject to avoid distortion and diagonal views.
Rule of Thumb 3.1
- For outdoor photography on sunny days (10 AM to 3 PM), set the ISO to 100 for optimal results.
Rule of Thumb 3.2
- Use ISO 100 for examination quality or critical comparison photographs for clearer detail.
Rule of Thumb 3.3
- During early morning, late afternoon, nighttime, or indoor shooting, opt for ISO 400 for better exposure.
Rule of Thumb 3.4
- For precise color capture, use midday sunlight or electronic flash, specifically between 10 AM and 3 PM.
Rule of Thumb 3.5
- In film photography, if overexposure must occur, choose to overexpose as it is easier to correct than underexposure.
Rule of Thumb 3.6
- In digital photography, prefer underexposure when necessary, as more detail can be salvaged from it than from overexposure.
Rule of Thumb 3.7
- ISO 100 film tolerates a 2 f-stop overexposure and a 1 f-stop underexposure correction; ISO 400 film, a 3 f-stop over and 2 f-stop under.
Rule of Thumb 3.8
- To prevent blur while handholding the camera, match shutter speed to lens focal length expressed in fractions.
Rule of Thumb 3.9
- Capture crime scene images ideally at a shutter speed of 1/60 seconds with f-stops of F/22, F/16, F/11, or F/8.
Rule of Thumb 3.10
- Before using apertures wider than F/5.6 for crime scene photographs, consider using electronic flash, a tripod, or adjusting the ISO for better results.
Rule of Thumb 3.11
- Attach filters to the lens with the lens aimed upwards to reduce the risk of dropping the filter.
Rule of Thumb 4.1
- Ensure all elements and evidence in a crime scene are in focus; recompose if areas will be out of focus.
Rule of Thumb 4.2
- Focus should cover the entire primary subject area to maintain clarity throughout the image.
Rule of Thumb 4.3
- Depth of field generally extends one-third in front and two-thirds behind the focus point.
Rule of Thumb 4.4
- For maximizing depth of field in crime scenes between 5 and 30 feet, specific techniques (not detailed) should be employed to maintain focus throughout the image.
