Portraits and People snaps

Which are the images that comes to our mind when we think of the word 'portrait'? 

Perhaps, the painting of our great grandfather hanging on a wall or the wedding picture of our parents in the family photo album. These portraits are the inherent characteristics of a person and moment of time immortalized within a frame. This is the reason why it is considered as sacred and lasting. A portrait photography is the one that spectacles the individuality and displays the emotion that may include fear, joy, love, sadness, surprise and anger of the subject under consideration. 

The portrait photography may be classified in to four types depending on our approach: constructionist, environmental, candid and creative approaches. 
The Constructionist approach involves building a certain ambiance around the portrait. For example: Happy Family, Romantic Couple, Blushing Bride, Confident Graduate etc. The Environmental approach illustrates the subject in their environment. For example: A child in a playground, A Student/Teacher in a classroom, A Vendor selling vegetables etc. The Candid approach is an informal type of portrait photography that includes photographing a person without their knowledge. For example: A child playing with toys, A pretty girl eating ice cream, An old man on morning walk, A chef preparing the dish etc. The Creative Approach is where digital manipulation is brought to bear to produce a magical, very attractive and visually appealing portrait.
