Contrast problems are very often we get in photography activities including me. portraits, selfies, or other activities almost every time we do. especially like me, this works in the world of photography. the type of contrast that we found is different. depending on how we take pictures, what devices do we use when taking pictures and how the weather's brightness is placed. This has a big effect on the contrast of each image produced.
Contrast is one of the important elements in photography. contrast clarifies the position of each element in a photo, which is the main element and which is a supporting element.
So, this time I will add a little insight and discuss contrast in photography so you understand. now, the contrast is not only between dark and bright light, but there are other elements in it.
There are three types of contrast, namely light, color, and texture.
1.Light Contrast

Light contrast is often called light and dark. Use a light contrast technique that is often used when shooting silhouettes at sunrise and sunset.
2.Color contrast
As the name suggests, color contrast is a color difference, for example between red and green, blue and yellow, etc. the point is to make a real difference if two or more colors are combined, where each color has its own strength.
3.Contrast Texture

The contrasting texture is the difference between coarse and fine. Rough and smooth here is not from the sense of taste but based on the sense of sight, for example between the model and its opaque background.
Contrast does not have to be clear, for example between dark and light, red and blue, and rough and smooth. Sometimes photographers like soft contrast to produce calmer photos where the difference is not very visible, for example, dark and rather dark, red and pink, and the texture is strong and smooth.
Well, that's a brief explanation of the contrast. this can be an important note in terms of photography.
like my friend who is on vacation outside the area to meet with his best friend, they have time to take pictures together before parting. But that happened. he was not aware that the photos taken had excessive contrast so that all objects almost faded.
It didn't take long to think, I immediately tried to solve the photo problem using the GIMP software. at first, I had difficulty dealing with it because the photo was taken with an ordinary smartphone. but I'm still trying to overcome it using GIMP.
You can see the steps I use in GIMP to overcome contrast problems!
- First, with the CTRL + O shortcut or select the FILE menu> OPEN, look for the image you want and then click OPEN.
- After the image appears, you can see many coloring features that you can use in GIMP, depending on your tastes and needs.
- Now that I try to apply the Feature to the Color Menu in the color menu, I apply Color Balance.
Color Balance is used to adjust the composition of colors based on the basic colors in the format of photos or images, there are 3 colors of coverage that will be adjusted, namely shadows, mid-tones, highlights (it is recommended to try all three because each photo will vary) and 6 basic colors Cyan, Magenta, Yellow, Red, Green, and Blue. Check Preview to see examples of changes.
- I apply Hue-Saturation
Hue-Saturation is used to adjust the color composition with a more specific method than the menu above. First, we determine first, what color (in the photo) will change, if you want it as a whole you can choose "Master". If so, adjust with 3 choices, Hue (color), lightness (Lighting), Saturation.
- I use the Colorize.
The color used to adjust the composition of colors by using automatic layers, so if our photos fix semi-transparent colors, saturation and light that can be adjusted, COOL !!!
- I Apply Brightness and Contrast implemented.
Brightness and Contrast are used to adjust the color composition with adjustments. This is a feature that most image manipulation programs have. This feature also won't change the color channel, so it stays on the channel, eg: red won't turn blue.
- I apply the Threshold.
The threshold is used to change the color to black and white by adjusting the black level based on the base color and diagram in the window that appears. Usually, this feature is used as a combination of features in the filter menu.
- Then I use Level.
A level is used to adjust the color composition based on the black level set through the window that appears, this feature does not cause black and white on the photo, because it only adjusts blackish content in the photo.
- I use Curves to adjust the color composition like the previous menu but it is displayed in the form of a curve.
- The next step we can use Posterize to adjust the color composition by reducing the colors found in photos or images.
- Then, use Desaturate to adjust the color composition to black and white by returning saturation. So it becomes colorless.
- Next, to the Autosub feature, everything will change the color composition automatically.
The following is an explanation of the above process:
Equate to equalize all colors at the same value.
The white balance will automatically change the composition of the color by matching the white value.
Color enhancements automatically enhance the color colors that are considered standard in GIMP. The alien map is one of the features that I like because the color transformation is cool, this feature has a method to change the composition of colors by adjusting the base color frequency in Photos.
Color Exchange, have you ever heard of money exchange? yes ... more or less the same method, which is changing the color found in the image with the color we want.
Rotate Color is a feature that changes the composition of colors by using a color circle that has an angle so that we can rotate to any part we want.
Colorfy is the same as colorize, but there are fundamental differences, namely this feature is simpler because it only adjusts the color layer, and there are already color templates provided.
The last one is Maximum RGB, this feature makes RGB color composition, to its maximum point, so the colors in the photo look less and more contrast.
In my opinion, the above features are often used because it is easier and faster to handle it. There are many other ways to deal with contrast problems in GIMP software, but you must clearly understand the functions of the features in it. If you already understand the functions of the features in it, you can easily solve problems in photos.

Summary
I'm sure with this article, you start thinking twice about using more pro manipulation software like Adobe Photoshop, etc.
Well, it should be. Because if we compare GIMP software. he will excel in terms of the speed of his working process compared to pro software. Pro software is very superior in terms of features, but not in speed.
In this article, I have shared what personal search can do for you. I have also reviewed the software when I did it. In my next article, I will discuss other important points about this topic (personal exploration).
