Calibrate screen in a few words

I will explain in this article simply about screen calibration, and why you should calibrate the screen in the first place, most people process their images with the screen as it is, and the images look good. Let's start with a simple example of why to calibrate the screen, an example I think everybody knows.

You've probably noticed that when you go into a TV store, every TV shows a little different color from the other. All TVs display the same image, but each screen shows different shades. Some screens show warmer tones than other screens that show cooler tones. The same thing happens on computer screens. Each screen displays other shades. Each screen company produces a few other shades, as well as screens of different laptops from table screens in shades and their technical capabilities.
I will not go into the physics of the screen's hues (at least not in this article, in another article I will expand on the subject), but each screen has a slightly different color. The reasons arise from things like: the type of parts that make up the screen, the quality of the different parts and the temperature the screen is capable of reaching. Another thing that will make us see these or other negatives on the screen is the type of software we use for display. As an example I will give the Windows 10 software whose display software drastically modifies not only the shades of the image but also the brightness of the image

Can ask the question - if every program and screen shows different colors and speeds, why should I calibrate the screen? Even so, everyone will see a different picture. So why is it so important to calibrate your screen, no matter which screen you're working with?
Each time you do an image processing, you choose some darkness and brightness. You decide how much color you can add and perhaps a color that is more late, and you choose what temperature to use to get the right shade for your photo. Even if you only control basic things, as we would once do in the process of development and printing, such as brightness, dynamic range,
Temperature, you still choose to handle the image in one way or another. For those of you who deal with black and white photography, here too, what the screen shows you is very important. Especially in the light of the now-colored camera, and we have to make the color black and white.
In fact, you do not really know what temperature you really chose, and you do not know the final tone you've received. Your picture may be more blue than you thought. You may have added more color than you wanted or too little. You may be sitting and processing black and white pictures in shades of brown and you do not really know how black or white or what shades of gray you see

And where will you know at the end of the process? The first time you send a photo to print. Then you'll find out what the colors really are, and you'll find that this is not the picture you've seen on the screen. If you think that's the problem with the printing press, then if you're printing in a professional printing house, I'm sorry to disappoint you, but the problem is not in the printing press. In a professional printing press, both screens and printers are calibrated every morning. The problem is that you could not really know what shades and intensity of light you received in editing the picture, so the problem is actually with you and only you.
You may not plan to print to the world as students sometimes tell me. Really to the world? I always ask. After all, you are getting better at photography. There is a good chance that in the end you will want to print one picture into the living room, and then what? You will find that the color is completely different from what you saw on the screen?

After calibration

so what are we doing? Calibrate the screen. How complicated is it? The easiest in the world! We follow the calibrating instructions, and everything happens on its own. What the calibrator does is actually check what the screen shows in relation to the light in the room, and then decide what the right shades are for you to know what shades and intensity of light you are getting in the image processing process

There are several calibrators in the market, better and less good. I work with the screen calibrator (Datacolor-Spider Pro 5). It is simple to install and easy to operate. It calibrates itself in a few simple steps and during work you can connect it to the computer and its "eye" reads the light intensities in the room and the program tells you whether the intensity of the light in the room is too strong or too weak to work. I chose to work with him for several reasons - he is very precise, and very easy to operate and calibrate the screen. The calibration process takes a few minutes, and I always can before sending to the printing press calibrate easily and quickly, and most importantly the result obtained is very accurate.
I've included some screenshots of the screen calibration process for this model. In general, all you need to do is follow the software's visibility and do what it asks for. The most important thing is that the screen will be warm enough (it will work at least half an hour before calibrating) and place the calibrator in place where the software prompts and from there not to touch or move the calibrator nor the screen

Indicate that we have indeed followed the basic requirements of the software


Select the screen type


Model Identification


Confirm how long you can control the screen


Calibrate from the beginning or maybe just a calibration test


The calibrating position in the place marked Waila set out. Now they let him finish the job. The easiest there is

If you have any technical questions or questions about the work that I'm working with and why. You can leave a comment at the bottom of the article and I will be happy to answer
