Taking Hemiphotos
SLM9 User Manual v1.2
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 the two or ten second timer
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.
Using PC Image Capture Software
The Canon EOS 60D 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 60D
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.
