		+	The following Python script will capture a picture from the Raspberry Pi camera every time it is called. The filename of the picture will be date and time stamped and saved to the '/home/pi/pictures' folder.
		+
		+	<pre>
		+	#!/usr/bin/env python
		+
		+	import os
		+	import time
		+	import commands
		+	from datetime import datetime
		+
		+	d = datetime.now()
		+
		+	initYear = "%04d" % (d.year)
		+	initMonth = "%02d" % (d.month)
		+	initDate = "%02d" % (d.day)
		+	initHour = "%02d" % (d.hour)
		+	initMins = "%02d" % (d.minute)
		+
		+	filePath = '/home/pi/pictures/'
		+	fileName = time.strftime("%Y-%m-%d_%H%M.jpg");
		+	fullPath = filePath + fileName
		+	cameraCommand = 'raspistill -o '
		+	fullCommand = cameraCommand + fullPath
		+
		+	os.system(fullCommand)
		+	</pre>
		+
		+	To capture images at regular intervals the script can be loaded as a cron job.
		+
		+	To edit the cron table type:
		+	<pre> crontab -e </pre>
		+
		+	The format of the cron table is:
		+	<pre> m h dom mon dow command </pre>
		+
		+	where m = minute past the hour, h = hour of the day, dom = day of the month, mon = month of the year and dow = day of week. So to run a script every day at 0735 hours would look like this
		+
		+	<pre>35 7 * * * script_name.py </pre>
		+
		+	For the timelapse camera the crontab was configured to run the script every 10 minutes.
		+
		+	<pre>
		+	crontab -e
		+	</pre>
		+
		+	Add the following line to the bottom of the text file.
		+
		+	<pre>
		+	0,10,20,30,40,50 * * * * python scripname.py
		+	</pre>
		+
		+	Save the file.
		+
		+	To check the contents of the cron table type.
		+	<pre>
		+	crontab -l
		+	</pre>
		+
		+	You should see the script in the table.
