Many times we wonder how it can be that there are images that can be seen perfectly when we zoom, no matter how infinite, and other times when enlarging the image it appears blurry and with "squares". In this blog we explain why it happens.
Everything we observe on our screen is made up of pixels or vectors. Thus. First of all, we are going to explain what each term is to get into context.
Vectors, as curious as it may seem, is a set of mathematical equations, lines that join different points on the screen. Being lines, and anchor points, you can expand it as much as you need, the good thing is that it will always look the same. What do we use vectors for? Normally, they are used to create graphic elements that will need to be in different sizes, such as logos, icons, etc.
When we approach a photograph, whether it is printed or on a screen, we can see how the image is made up of little squares or dots, called pixels. Each pixel has a specific color, so the more pixels it has, the more definition the image will have. If we want to measure how many pixels there are, we must take into account the DPO (dots per inch). If we want to print an image it must have at least 300dpi, while if you want it to be seen on the screen, it must contain 72dpi. One of the most notable differences between vectors and pixels is the colors. An image (composed of pixels) will always have a more realistic color combination, definition and results than a vector. Therefore, if you are going to work with photographs, we recommend using pixels, and if you want to create a logo or icon, use vectors.
How do you create a vector?
Normally to create a vector we will use the Adobe Illustrator program, which is a specialized design program. Regarding the format that we must choose for images or vectors, we can differences between:
: It is the most popular image format, although it is not the best option for printing, it is used mainly for web designs, since it has poor quality.
: It has better quality than the previous one, and it also allows you to export images with a transparent background.
: Perfect to send to printers or other designers, but being the Photoshop format it is not recommended to send it to clients if they are not used to working with this program.
: The file does not lose quality, perfect to send to print.
: It is a vector file format. Ideal for print jobs.
