what is ISO & APERTURE ?

Hi guys,

Welcome to the world of creativity, photography.

I'll be explaining you in a simple way not too long paragraphs to read just short and helpfull.

To learn today;

ISO 

               - Introduction 

               - Detailed explanation

               - When to use (how to manage)     

So let's begin,

INTRODUCTION

You can say that it's an artificial source of light in the camera itself which can make your photos/videos bright or dull.

DETAILED EXPLANATION

ISO is always seen in a range limits means you can set the values (we'll talk in a bit) in a definite manner as per requirement

(100,150,200,...).

These values are seen according to your device (DSLR, mobile, mirror less cameras).

All the devices vary their ISO range.

Like in ideal cases the DSLRs have a range from 100 to 15000 and in mobile the range is from 100 to 5000.

#Working: 

                  The working of ISO is a PIECE OF CAKE to understand it correctly.

1. ISO minimum value - less grains, requires adequate amount of light externally (sunlight is the best source of light or artificial spot lights) .

1. ISO maximum value -so much of  grains, requires a dark/ night scenes.

So now you were wondering what's grain means in photography.

To get a clear vision what I'm trying to say, see both the pictures carefully given below and comment down below what do you understood.

(1.1)Less grains

(1.2)More grains 

(1.1) This photo looks very nice, pleasant and attractive because of less grains indirectly the photographer had set the iso at the minimum values.

(1.2) This photo looks trash and not so attractive because of large amount of grains in it indirectly the photographer had set the iso at a maximum value.

Difference :-

1.1 The object's (girl) face has very little bit of grains surrounding her.

1.2 The object's face has large amount of grains surrounding her.

(If you are not able to see the clear difference just zoom the screen accordingly)

CONCLUSION

The simple conclusion is that according to the condition you have to either pump up or lower the values of ISO.

#TIPS:- 

          1. Minimum ISO - daylight or adequate                    amount of light. 

          2. Maximum ISO - night/dark scenes

APERTURE 

                      - introduction

                      - details

                      - summary 

Note:- This topic might take two/three posts as it's a bit tricky part of the basics though.

So let's begin,

INTRODUCTION

One simple question for you, what do u understand by the term APERTURE in first glance? 

Do comment down below your true thoughts.

Now moving on to the topic;

APERTURE is a small/big opening of the lens of the camera. You can say it as the "pupil of the lens".

It's used in the depth of field of the object in the frame or the Bokeh.

As I told you it's not a part of the camera itself it's a term used in the lenses used at front of camera sensor to capture photos/videos generally used in DSLRs.

These are the numbers/values to specify the sensor to expose the sensor.

Means APERTURE ensures that what amount of light should enter in the body on to the sensor of camera.

Aperture is a definite value written on every lens as f/2, f/8, f/1.2, and so on. 

In some lenses the slash ( / ) is omitted

Like F2, f4, f8 etc. It means the same.

NOTE:-

           "f" in the values written above will be                 explained  in  a  bit ( don't worry about                that ).

DETAILS

See the picture first to clearify what I'm trying to explain 

The white portion inside the lens is aperture

You will see the small opening of the lens that's the aperture which is today's topic.

So, this was just the appearance of aperture in camera lens. 

The actual mechanics is little bit tricky but I am here to solve and help you out, friends.

At last I would like to sum up this blog post by giving you tips of aperture to think it off a little bit.

Here are the tips :

1. If more the aperture value ( f16, f8 etc. ) , the Bokeh will be wider or depth of field will be lower.
2. If less the aperture value ( f1.2, F2 etc. ), the Bokeh will be narrower or the depth of field will be higher. 

I'll be explaining all the terms used in this blog post in future post, till then stay tuned.

That's all for today guys. 

Thank you
