I saw my friends and high school students tring to make a gray image (black-and-white image) using apps for a long time. It is a waste of time.
I will explain it and you can learn it within 1 minute.
First, gray image is a image without color. So just remove the color of your photo. Please see the photo below.
This time, I will use SATURATION function on Instagram app to remove the color.
I set the value of SATURATION -100.
SATURATION function is a basic function. It is installed in your smartphone. You just set the minimum value, so color in your photo will be removed.
That’s all. It’s very easy.
I will make one more.
I moved a slider to the minimum value.
The gray image shows the brightness level of each pixel in your photo.
Maybe you learned how to use photoshop. However, without basics knowledge about digital photos, you will waste your precious time. So I recommend you to learn basics first. It is very useful for your SNS life from now on.
See you very soon.
