Digital Camera Recommendations
Taking Diagnostic Images:
If you have to take a digital image in the field, use a
digital camera. If you have the option to take the physical sample to
your office, always use a scanner. Scanners give
the best digital images for diagnostics. The high resolution, color
definition, focus, and controlled lighting guarantee a sharp image.
A picture of a bug or plant problem often requires you
to get close, real close. Make sure that the camera you buy has a macro
mode and that the macro mode allows you to get close to the subject (3" or
less).
Shopping for a Digital Camera
Typically handheld digital cameras offer a
variety of image quality choices and connection
interfaces. Analog RGB video and analog
composite video (NTSC) interfaces will allow you to connect
the digital camera to a video conferencing system or to a VCR.
Digital formats allow you to connect your digital camera to a computer.
Common computer interfaces for digital cameras include USB and
IEEE1394 (FireWire™). Digital cameras may also use memory
sticks, CD-R's, or even floppy disks to transfer images to the computer.
For the GPDN diagnostics we suggest you shop
for a digital camera that provides high resolution images and a macro
mode that allows you to get really close to the subject. If available, a
(NTSC) composite video output is great for video conferencing.
