Content generated during The American Society of Ichthyologists and Herpetologists (ASIH) Annual Joint Meeting - 2016, during an iDigBio sponsored workshop by the following individuals participating in the "Field to Database" Group of the aforementioned workshop: Breda Zimkus, Cesar Aguilar, Ben Frable, Meredith Mahoney, Zachary Randall, and David Wernecke.
Recommended Equipment
- DSLR cameras: (Canon 5D, 7D, Rebel models, equivalent Nikon models; many options)
- -Optimal manual settings: ISO 100, aperture f.11-f.16, Shutter 1/200th
- -Image file settings RAW and JPEG files (JPEG low-resolution)
- Lenses: 50 mm macro, 100 mm macro, 24-70 mm non-fixed lens (i.e., wide angle frame)
- -Polarizing filter
- Tripod, flashes/lights
- Light diffusers
- Batteries, chargers
- Solid white background for imaging specimens
- Squeeze tank for imaging specimens in fluid
- - Dimensions: 15 in W X 12 in H X 5 in D
- - Font and back panels are glass (approximately 2.5 mm in thickness)
- - Sides and bottom are plexiglass (around 4 mm thickness)
- - The movable pane is plexiglass (15X15, around 3 mm thickness). This pane will get scratched over time, so you might consider tempered glass.
- Pelican case for housing tank
- Size scale bar/color standard/white balance card
- Large amount of fresh water (add salt for marine/brackish waters)
- Dark buckets (prevents stress and color lightening for fish)
- Aerator/bubbler
- Visor board with cutout lens to avoid reflection of tank
- Backboard color board (preference for gray, others use white or black)
- Grey, black or white background board for out of water specimens
Imaging specimens
- Lighting source (time of day, sunlight available; flash units)
- Image specimen alive to preserve natural color (some specimens can be anesthetized or relaxed using MS-222 or ice, clove oil, and then imaged for positioning)
- Photograph left side of fishes (standard side for measurement), unless damaged/atypical
- - If right side is photographed, note any photo-manipulation (i.e. image flipping)
- Retain the following within the frame for reference:
- - Unique identifier (e.g., include field/collector tag number, tissue vial number)
- - Scale bar
- - Color bar (white balance)
- Photos of site
- - Include photo of site name/label
Imaging Back-up
- Organize and back-up all digital image files at the end of each day
