When the distance between the subject and camera lens is 5 mm to 10 mm it is called Marco Photo. But the the distance between the subject and camera lens is 0 (zero) mm to 5 mm it is called Super Marco Photo !! Check the exampe below.
Picture 1
Picture 2
Picture 3
Good information about macro photograpy can be found at http://www.ephotozine.com/article/Close-up-photography

Coming soon more on marco as experiments goes on !!!!

Aperture and Depth of the Field!!!
Aperture is the size of opening in the lens when a picture is taken. When we click the photo aperture of the lens opens allowing light to fall on the sensor. Larger the aperture setting more the light gets in and vice verse.
Aperture is measured in ‘f-stops’ with typical values like f/2.8 (bigger lens opening), f/4, f/5.6, f/8 and f/22 (smaller lens openings) etc. Moving from one f-stop to the next will double or half its value. Note that the shutter speed controls time the amount of light through aperture should be exposed.
Consider the small example below. first part of picture shows bigger aperture only the tree is highlighted while smaller aperture entire house and background is visible.
This can be easy observed in two picture below with constant shutter speed of 1/60 sec.
Picture 1 with F/3.7. Subject is sharp and leaves in background are blurred and building is not visible.
Picture 2 with F/8 Subject is not as sharp as picture 1 and leaves and building are clearly visible.
So Larger Aperture (smaller f/2.7) to obtain a shallow Depth of Field and Smaller Aperture (larger f/8) to obtain a great Depth of Field.
Having control on your shutter speed and aperture setting we can have better control over exposure..coming soon... stay tuned !!!

Red Eye Effect !!!
Flash is required when there are low lighting conditions. But when trying to take a photo of human or animals then their eyes appear to be red with flash. This happens due to sudden enter of bright light enter into eyes and most of light is reflected by eyes. This reflected light is also captured by photo and eyes appear red. This is called Red Eye Effect.
Most of digital cameras have build in red-eye reduction mode which helps to remove red eye effect. What happens here is red eye reduction lamp fire when there is flash. This reduces the light reflecting back from the eyes and making them not appear red. Better results can be obtained when subject is looking right at the red-eye reduction lamp. Also, use some editing tools which help to reduce the red eye effect can be used.

Three Sixty Degree Angle !!!
There are times when the photos don't fit in single snap. So click photos in small size and join to get the wide angle snap. Check some examples below.
Rogers Center
Niagara Falls and Rainbow
Giant Wheel and CN Tower
Bridge to US, American Falls and Niagara Falls
Lastly Toronto Downtown
Wait for 360 degree angle photo.. coming soon ...stay tuned !!!
