Practice 4: Focal length x Asking a stranger's permission

The lesson has taught us two things:

One is to try shooing photos with different focal lengths but with same setting and object,

Second is to try asking a stranger's permission to take a photo of them.

I. Focal Length

50mm focal length of camera is similar to human eye,

because of the similarity of angel between two.

The practice is to try three different focal lengths:

the smallest, 50mm and largest,

so to shoot the same photo under the same setting

by moving our body further or nearer

and to find the differences among 3 photos.

The lens i used was 18mm-55mm,

so these photos were taken in 18mm, 50mm and 55mm respectively.

18mm:

50mm:

55mm:

While looking at these photos carefully,

especially at the change of background,

I discovered that the smallest focal length of lens is using,

the shallower of the depth of field,

which means the more blur of the background.

Also in the photo which taken in 18mm focal length,
the object seems much nearer to us and the background is further from us.
It is totally opposite to the photo which taken in 55mm;
which the object seems further and the background is closer to us.

II. Asking permission of stranger

As a photographer, we can't always do the candid photography as the only type.

Or if we do, the object (person) may feel uncomfortable and not be respected
if we have not ask their permission first.

So, the practice is to enhance our self-confidence and braveness,

to ask random people if we can shoot some photos of them.

Normally, if i approached with smile and polite manner,

most of them would say yes.

I think the strategy of choosing a stranger to take photo is

not to choose people in a rush, at work or talking in phone,

because if they are  having their own business to do,

we better don't interrupt them.

The more relaxed of the person,

the more natural photo we can get.
