Thanks,I had it set on manual at 5.6,8 would give more depth of field in focus.
auto focus,iso80,and 200th second shutter,(using flash),as it was a bit windy.
If not windy then you can get these with a slower shutter speed,and set it av(aperture priority).
I set it to macro,but its not nescesary,but the trick is to getthe dedicated canon filter holder £45 part no (fa-dc58b),this will hold a 58mm filter,or any size filter with a step down ring(£3or£4),Then run around phoning shops etc to find an 'acromatic'close up filter,(these filter/lenses)are made of two bits of glass,and give far superior images than the common close up filters.
Then set the camera to a high optical zoom,this gives you about a foot between the lens and subject so you dont spook them,and it lets the light on your subject as you are not right up against it like you are in normal macro.
If you use the digital zoom as well,you would get even more magnification!
You can buy new acromatic filters such as Raynox DCR 150 and 250 for about £35/45,but I just bought them from a camera shop second hand for £8 for two sigmas they have different magnification streangths.you can use them one at a time,or stack them for smaller subjects,the quality of these filters is superb,canon do some too,but they are hard to get.Any settings will get the picture,but to get in close,and from a distance,its the filter addapter & achromatic filter that do the job,what they are up to is allowing you to use the cameras lens at its longest(highest magnification),and focus closer to the subject.
If you are after this kit for your camera,you can get the canon addapter from any canon dealer,or online,the achro filters take some looking,but I have done that and could source you some the same as those I use as the shop had a few of them second hand and good.
Hope this helps,and that canon addapter can hold any filter,plolariser,skylight,etc,and protects the lens and gives you a better hand hold on this small camera.
Sorry for the prolonged post!give me a shout if you get the canon bit & I could lend you the filter setup to try.
