Graffiti is a reflection of culture. It tells the story of a place and its people. I feel that graffiti is often seen as a form of self-expression and can be used to convey a message. It can also be a way for artists to showcase their skills and creativity. In fact, some of the earliest examples of graffiti were found in Pompeii, where people would write messages and draw pictures on the walls of buildings. Graffiti has been used for many different purposes throughout history.

In organic chemistry, the term “catenation” is used to refer to the bonding of atoms of the same element into a series . Also known as the tendency of self-combination. This takes place most readily with carbon atoms .

Carbon atoms can form long chains by sharing their valence electrons with other carbon atoms .

This is not to say that carbon is the only element capable of forming such a chain; other elements capable of catenation include hydrogen, boron, silicon, phosphorous, sulfur, and halogens.

This occurs only with elements that have a valence of at least two and can form strong bonds with themselves.

Electric charges, which can be positive or negative, produce electric fields. Do you know that a moving charge also produces a magnetic field? There are two types of charges “positive charge” and “negative charge.” The positive charge is exhibited by protons, whereas the negative charge is exhibited by electrons.

Electric charge is carried by electrons and protons within an atom . We know that protons and electrons attract each other and two protons or two electrons repel each other.

The unit of electric charge is “metre kilogram second” and the SI unit is “Coulomb” .

A string is a list of characters in order. An empty string is a string that has no characters. Python recognizes as strings everything that is delimited by (” ” or ’ ’)

I have practiced some, so I will show you those

String is the collection of characters . A string can have a single or multiple characters .

String can also be multiplied by any integers.

Adding a number to a string produces an error .

Let’s begin with “Backslash”. Blackslash inserts a single black slash. I will show you now how the output comes out.

“Single Quote” adds a single quote within a string.

“Tab” adds spaces of 8 characters.

“New Line” takes the cursor to the first position of a new line.

“Carriage Return” takes the cursor to the first position of the same line.

Let’s begin with the addition operator, which adds values on either side of the operator. Now I will code this and show you how it works and how the output comes out.

Now let’s see how to use the subtraction operator, which subtracts the right-hand operand from the left-hand operand.

Now let’s see how to use the Multiplication operator. It multiplies values on either side of the operator. We use asterisk (*) to multiply.

Now let’s see how to use the Division operator, which divides the left-hand operand by the right-hand operand. We use a forward slash (/) to divide.

We use the print function to output text.

When we code like this, we will get the output as follows:

The text should be enclosed into single or double quotes . The print statement needs to be followed by parentheses, which enclose the output we want to generate.

In this case, the output will be the same as above.

HTML, also known as the Hyper Markup Language, is the standard markup language for documents designed to be displayed in a web browser. It describes the structure of a web page. It has some building blocks known as HTML elements.

I have used HTML in replit and in this blog article I will show you how I have done it.

When you sign up or log in, you will get this interface where you will get the option to create a new one.

When you click on a title, you will get an option to select the language.

I have selected the HTML language.

After selecting HTML, you will get this interface.

Now you edit the code according to your needs and run it. You can see the output.

White balance has an important role in photography. White balance is something which has a direct connection with the temprature of the picture. It tells the intensity of the light.

While clicking the pictures, not all lights are equal. Here I am not talking about the quality of light but the different colours of light, which are referred to as colour temperature.

How to understand the nature of image ?

When the image is more blue in tone, the image is cooler, and when the image is red in tone, the image is warmer.

When we are clicking the picture in manual mode, we get the option of controlling some settings for the picture. White balance is one of them. Even in manual mode, we can keep the white balance in auto mode, but if we need to keep the temprature of the picture according to our connivance, we have that option.

We can adjust the kelvin value setting to a higher number, which is cool, or a lower number, which is warm, according to the situation.

Different Kelvin Values in White Balance

While clicking in manual mode, we keep the white balance setting according to the scene we are clicking on. Every white balance setting has its own kelvin values, which is known as Kelvin temprature.

I have clicked some pictures in some white balance settings, which you can see further.

Some of the white balance settings are incandescent (2500 to 3000 K), daylight (5500 to 6500 K), fluorescent (4000 to 5000 K) and cloudy (6500 to 8000 K).

Effect of White balance on an image

These are the results of clicking pictures in daylight with different white balance settings and keeping the other settings in manual mode as Auto.

These are the results of clicking pictures in low light with different white balance settings and keeping the other settings in manual mode as Auto.

Now while seeing this picture, you might think that these pictures are looking so dull, so let’s jump to that.

Relation between White balance , ISO and Shutter speed

So you can see in this image that by keeping the ISO at 1600 and the shutter speed at 2, the image becomes clearer and brighter.

I am not saying that you should keep your settings exactly like this, but the main point is that while changing the ISO values and shutter speed values, the image becomes better than before.
