Taking the Picture
To ensure the camera is level it is often easiest to use the timer or a
remote control to take a picture.
The Canon user manual describes a range of suitable remote control
accessories which you may wish to acquire. Here we describe two
methods you can use if you don’t have a remote control.
Using Timer
See Self-Timer Operation in the Canon 50D
user manual
1
Press the AF DRIVE button.
2
Look at the LCD panel, rotate the dial
Select
for two seconds
or
for ten seconds
3
Press the shutter release and move the
camera and SLM into place, checking it is
as level as possible, and pointing to
North. Hold it still until the timer
completes.
The beeper will sound, the self-timer lamp
will blink, and the shot will be taken about
10 seconds later.
Using PC Image Capture Software
The Canon EOS 50D camera comes with a USB serial cable for
connecting to a PC and Canon software on CD for acquiring and
managing image files from the camera.
As an alternative to using the timer you may control the Canon 50D
remotely via the USB serial cable connected to a notebook PC
This has the advantage of allowing you to immediately inspect the image
at high resolution, take another if necessary, and if you wish, analyse the
canopy on the spot using HemiView.
But to do this we recommend use of a ruggedized notebook or tablet PC.
