This

the

The

larger

the magnification ratio,

the larger the subject appears.

The

magnification

indicates

the

ratio

of

When

the

An

aperture

diaphragm

is

a

mechanism

that

controls

the

amount

of

light

entering

a

camera

through

the

lens.

By

adjusting

the

opening

of

the

aperture,

one

can

vory

the

depth

of

the

zone

of

in·focus

elements.

If

the

aperture

is

wide

open

1f/2.8,

for

exomple),

the

focused

area

becomes

shallow,

resulting

in

greater

blurring

of

images

in

front

of

and

behind

the

subject

in

focus.

In

contrast,

if

the

aperture

is

small

(f/22,

for

example"

the

focused

area

becomes

deep,

resulting

in

greater

clarity

of

images

in

front

of

and

behind

the

subject

in

focus.

The

benefits

of

brighter lenses

In

a

lens

description -

such

as

"EF·S60mm

fj2.8

Macro

USM

-

Ifj2.8"

refers

to

the

widest

opening

of

the

lens

aperture.

When

this

"f"

number

is

low,

the

lens

is

considered

"bright" or "fast."

Bright

lenses

not

only

capture

beautifully

blurred

backgrounds

but

also

let

you

choose faster shutter

speeds

even

in

dark

places, reducing

the

risk of undesired blurring

through

"camero

shake."

A number related

to

the

angle

of

view

of

a lens.

AEB

automatically creates three photos

with different exposure levels

If

you

use

the

AEB

(automatic

exposure

bracketing)

function

on

your

camero,

one

shot

generates

three

images

with different

exposure

levels.

Afterwords,

you

can

pick

the

best

result

from

among

these

three

choices.

Freely control the brightness

of

photos

Automatic

exposure

is

intended

to

create

optimal

photo

exposure.

However,

you

can

intentionally

change

the

exposure

level

through

exposure

compensation.

When

you

wont

to

get

brighter

results,

just

set

the

exposure

level

on

the"

plus"

side;

when

you

want

to

get

darker

results,

set

the

exposure

level

to

the

"minus"

side.

1/28

Exposure

determines

the

overall

brightness

of

photos.

Exposure

compensation

allows

the

photographer

to

get

"brighter"

or

"darker"

results.

The

shorter

the

camera

to

subject distance,

the

greater

the

blurring

in

front

and back of

the

focused area.

Making

the

subject

the

center

of

attention

requires

that

the

photographer

take

great

care

in

determining

the

focus.

Since

"camero

shake"

happens

easily,

use

of a

tripod

may

be

necessary

in

many

cases.

The

the

focal

length,

the

greater

the

the

narrower

the

In

other

words,

lOOmm

or

180mm

macro

lenses

have

narrower

angles

than

that

of

if you're shooting
