Hey folks,

Today I start with a series of articles about **Photography **on our Blog! I will show you at the beginning **the basics** and after this I will write **tips for a blurrier background**, for more **interesting light**. Also I will write about which are the perfect lens for your face (**perspective distortion**) and at the end I will write a summery and give especially **tips for fashion blogger**.

This series will have** 6 Parts** and I will post every** INSPIRATION TUESDAY **a new one. **Stay tuned!**

But Know let’s start with **part 1**:

**Basics – Aperture.**

The **aperture is a small hole in our lens**. You can change the size of the aperture. So the **picture gets brighter, if the hole gets bigger** or **darker if it’s get smaller**.

An important side effect is, that if the **aperture hole gets bigger, the background and foreground gets blurrier**. But my object in the focus **stay sharp**.

We don’t want an **overexposed or underexposed picture**, because of that we need numbers to control the aperture. Therefore we have the **f-numbers**. The numbers are **fractions** for example: **„f/1.4“**. But is the picture brighter at „f/1.4“ or „f/5.6“? So if we look at the f-numbers as fractions is** „f/1.4“ bigger as „f/5.6“ and also it’s brighter**.

If this is to complex for you (*like every photograph*), you just can **skip the „f/“** and just say „**aperture 1.4**“. Then you just have to remember: **the higher the f-number the darker the picture**. For example: „5.6“ is darker as „1.4“. Also the background and foreground **gets blurrier with a smaller number**.

To know **how much** 1.4 are brighter than 5.6 we need to learn the **row of f-numbers**. The light gets **doubled **if you go one number left and **halved **if we go one step right. The most cameras have **numbers between the „whole f-numbers”** for example: **1.8**.

**The f-number row: 1 – 1.4 – 2 – 2.8 – 4 – 5.6 – 8 – 11 – 16 – 22 – 32 – 45 – 64**

How much you can open or close the **aperture depends on the lens**. The name of that property is **maximum aperture**. The maximum aperture means the **smallest f-number of the lens**. For example: **„f/1.8“.**

**Summary**: The bigger the aperture hole, the smaller the f-number for example: 1.2, the brighter the picture and blurrier the background and foreground. The maximum aperture is the smallest possible f-number of the lens.

Tip: Do you want to test to photography with different f-numbers? Just use the “Aperture value” modus in your camera (Canon Av, Nikon A). So you can choose the aperture and your camera will find the perfect time for a correctly exposure. You can just experiment with different blurry backgrounds without have to check every time the exposure.

**Caution!** A higher f-number is **not a guarantee for a sharper picture**! If you use a bigger aperture hole you will get **diffraction**, that means the pictures is getting blurrier with a higher f-number. So for the sharpest picture you **shouldn’t choose a higher f-number as the diffraction limit**. You can easily find out the limit by searching in Google:* [Camera xyz] diffraction limit*.

At this point I will not explain what diffraction is. But if you interested in the topic „prefect sharp at pictures“ I will write an article, just let me know in the comments :).
