We will give you a detailed analysis of examples of fireworks with a black background using channels.
Tutorial sharing:
Generally, you can use filters or other methods when performing Image cutting, or directly use magic wand tools. However, you will find that the filter mode causes problems such as brightness and color difference. Black is often left in the background when you use the common image cutting method. The solution is to recreate the color channel to remove the black part.
There are many ways to map materials such as fireworks. If it is a dark background, you can directly change the mixed mode of the materials to "color filter"; or you can directly select the Magic Wand tool, but when the background is colorful, the fixed color will also change color in the color filter mode. Here we will introduce a very practical method. The process is to call up the three channels, red, green, and blue, respectively, fill in the red, green, and blue solid colors on the layer panel, change the mixed mode of each layer to "filter color", and then merge the layers.
First, let's look at the source image and the effect chart.
First open your channel tab.
1. Ctrl + Left Mouse Click thumbnail and select red Channel
2. Go back to the layers tab and press Ctrl + shift + N to adjust the foreground color of the new layer to a pure red Alt + DEL fill.
3. The effect is shown in the figure below.
4. Fill in with pure red color. After filling, hide the new red solid color layer and create a solid color layer based on the green and blue channels. The effect is shown in the following figure.
5. Change the layer mode of the three layers to filter and then Ctrl + N.
6. In this way, the object will be extracted from the pure black background. Isn't it very easy? In the future, you will encounter such a complex image. You can try it more.
Okay, the above information is a detailed example of using channels to capture fireworks pictures with black backgrounds, as you can see, I believe that everyone here is very clear about the method, so you can try it by yourself according to the tutorial shared above.
