A pixel is the basic element of the two-dimensional digital image. At the same time, a pixel is also the physical element of the display matrix. In the raster format images are displayed on the most of the image output devices: monitors, printers, cell phones, etc. The width and height of the image in pixels are the image size. And the number of pixels per inch PPI is the resolution of the image. The higher is the resolution, the more pixels are located in one inch.

And the smaller a single one will be. Thus, the more precise will be the details of the image. High definition images are a consequence of a greater resolution.

Resolution determines the clarity of the objects and text on the monitor. At high resolution objects on the screen become smaller and look sharper. Monitors usually have standard 4: 3 or widescreen 9 and dimensions. This is the screen ratio. The number of pixels horizontally and vertically is the screen size. In printing the resolution is measured in DPI, dots per inch. For the photo to be of a normal quality, a resolution must be at least dpi. For example, to print a photo on the A4 piece of paper xmm or 8x11 inches, we need to multiply 8 by and 11 by And get xpx.

This should be the minimum size of the picture for printing on A4 sheet. If the size will be smaller, the printed image will be fuzzy and blurry.

RGB color model stands for Red, Green and Blue is an additive color model in which those three main colors are mixed together to create other colors. RGB color system is suited for surfaces that produce their own light. The screen surface of a computer monitor or a TV set is originally dark, so its original color is black. All other colors are obtained by using a combination of the three main colors, which in their mixture must create a white color.

Experimentally it was proven that red, green and blue are the most suited for human eyes. As we know, the surface of the screen is not solid, it consists of small dots called pixels. Each pixel consists of three blocks, red, green and blue.

By varying the brightness level of each block we can get different colors. The information about the brightness level is encoded using binary code. For example, the most common for modern displays bit True Color system uses three bytes with values from 0 to for each pixel on the screen.

Absolutely red color will have a value This means that the amount of red color is full, of the green is 0 and of the blue is also 0. Absolutely blue color will have a value of 0. With different combinations different colors are formed: bright-violet is RGB color can also be encoded with the help of the hexadecimal system.

Here are some standard colors:. This color system is called additive. In other words, we take black color no color and add primary colors to it, mixing them all the way up to white. This way we can encode 16 colors, which is more than enough for human eyes. In a word, alt tag is an abbreviation of what is essentially an alt attribute on an image tag showing a nature or a content of its image.

That is why each image on any successful website has its alt tag that describes what is actually on it. As a result, various screen readers will make the image from your website accessible while reading out this alternative text. To illustrate the situation, that is an example of a complete HTML image tag:.

So, why does one need alt text for their images? As it has already been mentioned, the alt text literally tells what an image depicts as well as describes the main function of this image on the web page. Generally speaking, you just propose a person to use some services or buy some products that you provide with the help of this button. Thus, its alternative text simply explains what the button is used for.

As you can see, there is nothing complicated. Here is another simple example of using alt text. As you can see from the screenshot below, this blue call-to-action button lets a person get a shown website template right now.

What is more, talking about the image buttons, you could also put some extra call to action text to it. Actually, it is quite popular policy, so I am sure that you have seen such things a plenty of times while surfing through the web space. Below you can see the next example of this function. Keep in mind that every image you want to use for your online project should have its own alternative text.

In point of fact, visually impaired and blind visitors of your site will also use alt in order to figure out what an image or a button is for. What else should you know about it? Ok, now you know a lot of information about the pluses of alternative text. Still, I know what you are thinking about right now: what should you do in case your image does not have a clear purpose?

Without a doubt, it is a logical question, so let me tell you a couple of words. First of all, remember that the images that you would like to use simply for the design of your website should be in your CSS and never in your HTML code.

Shortly, the empty alt attribute looks like this:. To make things clear it is here to make sure that screen readers will pass over the image that has no purpose. For today it was all the information about alternative text. To sum everything up, below you can see the list of the main functions of alt text.

Thus, giving your images an alt text is an easy but important thing. In addition, remember that this text may be provided in the alt attribute or in the surrounding context of your image. I hope you will remind all the given points because they are the main rules of a successful alt text creation. Also, you may watch this video from Matt Cutts that was made in order to help you with a nice alternative text creation. Still want to know more about alt?

In this case, I have a lot of useful articles to share with you! Furthermore, I would like you to tell me your own definition of alt! Maybe you have something to add? For this simple reasons, just leave your comment below!

To begin with, CMYK cyan, magenta, yellow, key is the abbreviation for the name of the scheme, which combines the primary pigments. Thus, C means cyan aqua , M means magenta pink , Y is for yellow and K stands for the key. As you may know, these days K color means black in the modern printing world.

Still, things have not always gone this way. Historically, there were other colors used for Key: brown and even blue. Honestly speaking, people used the color that was the cheapest ink to get for their needs. That is why today there are a lot of various draw and paint programs that are able to make use of both mentioned color models.

Still, keep in mind that the CMYK model is usually used for the creation of the printed color illustration. On the other hand, the RGB color scheme is mostly used for the computer displays. Without a doubt, there is a difference between color and pigment. What is more, it is a fundamental one! To make things clear, a color depicts the energy that is radiated by a luminous object.

Consequently, a red area that you may see on a cathode ray tube will look red, as it radiates a big amount of light in the red portion of the electromagnetic radiation spectrum that, by the way, means nearly nanometers , and there is much less light radiated at another wavelength. Talking about the pigments, they are opposed to the colors and represent the energy that is not absorbed by a substance such as paint and ink. As it has already been said, the primary pigments are cyan, magenta and yellow.

In addition, from time to time black Key color is also may be a primary pigment. All in all, black can be easily made if one combines the mentioned below colors in the large and equal amounts. So, keep in mind that if you see magenta pink ink on some pages, it looks so because it literally absorbs a big amount of energy at all the visible wavelengths except in the pink part of the spectrum, where is reflected the biggest part of the energy.

By the way, did you know that the primary colors and the primary pigments are mathematically related to each other? As a result, if one combines any 2 pure radiant primary colors that still are red, green and blue , the will produce radiation, which will have the appearance of 1 of these pure non-black primary colors that are cyan, magenta and yellow.

On the other hand, if you combine any 2 non-black primary pigments, this action will give you a substance that will have the appearance of one of the pure primary colors written above. For these simple reasons, just leave your comment below!

When it comes to a digital image resolution or its size, we pay attention to the number of pixels along the height and length of the digital image. In addition, the more pixels the image contains - the larger it can be printed or displayed on the monitor saving a perfect quality. If you want to print an image of a certain size, you definitely need to pay attention to a DPI. Speaking of the size of an image in pixels, you will get a photo with x megapixels.

To save you from messing up, we will explain to you another side of this abbreviation. Another meaning of DPI comes as a methodology of statistics data accumulation, approvement, and network packets filtering due to their content. This deep packet inspection can analyze not only various packet headers but also the full amount of content that reaches second and higher OSI models levels.

DPI can easily detect and block viruses, moreover, it filters the info that does not meet any specific criteria.
