Super Marco !!

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.

Twilight !!!

Sometimes due to bad light photos cannot be sharp. But if slight hand shake during night photography can be some dramatic impact in photography. check some examples below.

Giant Wheel



City Twilight


Niagara Falls @ Night


More artistic photos can be click ... coming soon .. stay tuned.

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 !!!

Chromatics !!!

Chromatics is the Science of Color at times helps to pick your Object of Interest from rest of your background. Check some examples below.




one of my best picture !!





Hope this helps you !!

Auto Focus Dilemma!!

Most of the digital cameras operate in Auto Focus (AF) mode in which camera`s focus on the subject in the center area of the screen.

Consider the photo below with correct focus. When the focus is correct the subject is sharp and rest of picture in background is blurred.
For example check pictures below with correct focus. Background is blurred and subject (boy) is sharp. This is correct.



Correct focus again !!

However, there are some potential disadvantages with auto focus. It will fail when the subject is not in the center of screen or when shooting low contrast images and fast moving objects.

For example the image below where the subject (flower) is not in center of the screen. Simplify moving the subject into the center could have solved the problem but there will times then subject is not position centrally.





In picture below Subject is in the center but still the focus is on the background. Subject is blurred. This is incorrect image.


There are ways to solve the Auto focusing problem .. coming soon...stay tuned.

Control your Speed!!!

Dramatic impact in photography can be achieved by controlling Shutter Speed of your camera. Shutter speed measured in seconds. Unit of stops up and stops down on each value will half or double is used. Shutter speed can be 1 sec, ½ sec, ¼ sec, 1/8 sec, 1/16 sec and so on.

High shutter speed may be required to capture fast moving objects like car in motion or running man. High shutter speed may be required while taking photograph in bright light so less amount of light on sensors.

Slow shutter speed is required in order to catch subject in motion like smoke, rain drops and fountains. Subject will start to blur the rate at which it is moving.

Generally, a fast shutter speed can freeze action while slow speed can blur your image. This can help in dramatic change in appearance of photo.

For example:

Picture 1 below with shutter speed of 0.01 sec





Picture 2 below with shutter speed of 0.3 sec (photograph by Bharath Pangal)



Shutter speed of picture 1 is more than shutter speed of picture 2 and water from fountain appears in picture 2 has looks like hand brush painting.

Avoid Clicking Blur Photos

There are two reasons for photos being blur are Shutter Speed or Shaky-Hand Movements.

Most of digital camera operates in Auto Mode. In Auto Mode Shutter Speed is high enough to avoid camera shakes. However if you have manually changed setting in camera to show Shutter Speed then photos may come blur. Check your camera settings.

To avoid blur photos due to Shaky-Hand Movements try to your camera firmly with both hands, relax your arms against the side of your body, take a deep breath and click the snap and hold it for count of two.

If still not possible make a use of Tripod.

Below are some of the blur photos due to Shaky Hand Movements during snaps


Since the light is sufficient so shutter speed was not a problem. Sarcastically too much of rush to click the snap.


Too much was rush again !!!

Slow shutter Speed can result into more resourceful photography and sometimes with shaky hand movements too. Coming soon!! Stay tuned….

Rules of Thirds !!!

The rule of thirds is a compositional rule of thumb in photography. The rule states that an image can be divided into nine equal parts by two equally-spaced horizontal lines and two equally-spaced vertical lines. The four points formed by the intersections of these lines can be used to align features in the photograph. Proponents of this technique claim that aligning a photograph with these points creates more tension, energy and interest in the photo than simply centering the feature would.

Before you snap the picture, imagine your picture area divided into thirds both horizontally and vertically. The intersections of these imaginary lines suggest four options for placing the center of interest for good composition. The option you select depends upon the subject and how you would like that subject to be presented.
