Many people think that image processing and editing are the same things. However, as a professional designer, you need to understand the differences between them, even to explain to clients when necessary. Click https://photolemur.com/blog/best-photo-books for more guide on it
Image processing is a natural process of digital photography. It can be done automatically by the camera, which generates the file. JPG format with pre-defined parameters or programmed by the person taking the picture. Therefore, we can say that in every photo, there is already some treatment. However, the image treatment needs to be done by a specialist to ensure professionalism in work.
In the age of analog photography, the choice of the type of negative film directly affected the final result of the photo. Although we no longer use films, many other cares are needed for a quality final result. Here are some valuable photography tips for you. Among the features for image treatment, the most used by professionals are white balance, hue adjustment, saturation and brightness, sharpness adjustment, and filters which can be seen in photolemur.
You may have noticed that photos in the same environment may have different tones (some are more yellowish or bluish). The cause of this effect is the white balance performed by the camera.
Each type of light produces a glow with a characteristic color; however, we do not notice these variations in our daily lives, as our eyes can automatically correct the hue of the lights. The camera is not trained to do this, so this type of adjustment needs to be done in-camera or post-production manually.
In this way, it is possible to make a photo taken at midday look like it was taken at the end of the afternoon by decreasing the amount of white and increasing the blue, for example.
Hue, Saturation, And Brightness
Hue is a property that allows one color to be distinguished from another. So when we change the hue of a photo, we’re adding or removing colors from the photo, changing the original shape. It is a process widely used in image processing.
Saturation is the perception we have of a specific color in the image. This is, in fact, one of the most used secrets in image treatment, as it makes a photo look more vivid and with more intense colors.
Finally, brightness deals with the clarity of an image; the brighter the photo, the closer to white it will be, and, consequently, the less bright, the closer to black.
Sometimes images may come with unclear outlines, especially when the source is a scanner or a simple camera. These images can benefit from a sharpness adjustment, in which the degree varies depending on the camera’s original quality. However, this adjustment does not affect photos that are originally poorly sharp.
Several types of filters can be used in image processing. One is the color filter, which has the effect of a one-color film with transparency over the top of the photo. So, you can make a photo more bluish, for example. On the other hand, an image’s blur filters can result in interesting effects, depending on the result you want. They are a little less used in image processing, but they are also important.
