Exposure compensation
Modern cameras are equipped with a built-in exposure meter, which is able to automatically assess the level of illumination and select the appropriate values of the exposure parameters. If the…

Dynamic range
Light falling on the photodiodes of the digital camera matrix is converted into an electrical signal. For this to happen, the number of photons that hit each individual photodiode must…

The purpose of color correction

Color correction is a purposeful change in the color components of an image to achieve a better result. In other words, it is a substitution of the original color, tone, shades, and saturation.

The purpose of color correction
The main reason why we sometimes resort to color correction is the significant difference between the image that we see in front of us when photographing from the result in the picture.

This situation, when the real colors in the photo look completely different, happens quite often.

This may be due to an incorrectly configured camera, low quality shooting equipment, and lighting features. Of course, technology cannot adapt to light in the same way as our eyes. That’s why there are distortions in photos.

But there are other reasons for using color correction:

A lack or excess of contrast of the image;
Image fading.
What is color correction and why is it needed?

Color defects include:

Photo highlights;
Excessive darkening;
Fading of shades and colors.
In addition, color correction is used to bring harmony between photos and the design of the publication, or, for example, the content of materials. This is akin to the process of photo printing in photo art.

Creative experiment
Like other methods used in photographic art, color correction can be used as a tool for implementing creative ideas or customer wishes.

What is color correction and why is it needed?

Using this tool, you will be able to add a picture of fabulousness and brutality, colorfulness and gloom… Everything will depend on your idea.

Main ways to use color correction
Most often, color correction is performed in Photoshop.

Methods of its application are completely different; let’s talk today about the most popular.

Specifying arguments for functions that convert input values to output values
These tools are called “levels”, “gamma”, and other similar tools. It happens that sets of argument values are selected from a list of pre-set options.

It is logical to refer to this type as well:

Setting the white balance when converting an electronic matrix signal to a file or scanning memory;
Transformations that directly set changes in contrast, brightness, gamma, tone, lightness, and saturation of the image (or parts of it).
Direct setting of graphs for converting values by channels
The name of the tool is “Curves”.

It is used to perform any kind of conversion in each channel. To do this, a graph is generated manually, similar to those calculated by functional algorithms using the specified arguments.

The Curves tool is very convenient, and can be more flexible and visual than individual functional transformations.

Enthusiasm is the basis of success. No creative activity is possible without enthusiasm. Nothing can replace it. It is much more important than any knowledge and experience, because it itself…


Can I fix the errors later?
As for the exhibition, no, you can't. Overexposure is not allowed in digital photography. Even if you shoot in RAW, the capabilities of RAW converters (contrary to the assurances of…


Accessories and settings for taking photos in the dark
As you know, the darkness is arranged in such a way that it absorbs everything around it. That is why it is not possible to take a high-quality picture without…
