If you plan to use photogrammetry to record quantitative data, a DSLR camera is required. Lenses are measured based on focal length (the number before the mm on your lens).
The wider a lens (lower mm number), the more you are able to capture in a photo, however with a 24 mm lens or lower you’ll start to see distortion around at the edges of your frame. Do not use fisheye or wide-angle lenses because they cause too much distortion. Higher numbered lenses have less distortion but are also much more expensive. Prime lenses have a fixed focal length: you cannot zoom. They can produce very high quality photographs because they minimize noise and distortion, resulting in an extra sharp image. Optional: black pedestal for your object.Lighting: we like photographers LED lights on tripods that you can move around, add light filters etc.Black background and base (ideally photographers black drop cloth, or felt if necessary).White Light box: this will diffuse the light so you don’t get harsh shadows.Optional: lint roller (to clean the black backdrop if necessary).If you have a good prime fixed-zoom lens within 24-70mm range, use it! A polarized lens cover will also help to reduce glare if your object has a shiny surface. We will be processing the photos using a program called Agisoft Metashape Pro.
