Primary color hole photography

But mixing pigments together will have the opposite effect. Because each pigment can only reflect part of natural light with our naked eyes, it will absorb more and more visible light when mixed together. If there are enough pigments mixed together, pigments can hardly reflect visible light, so what appears before our eyes is either black or very close to black. Some words should be written in the front: we are not all engaged in scientific research, nor are we engaged in academics. There are many questions of principle. The official explanation is embarrassing and difficult to understand. I will use more simple dialogue words to describe it. Such a small partner is also easier to accept and understand, so there may be incorrect explanations in the future, please understand.

When taking pre-war photos, photographers take their own satisfactory photos according to their own aesthetic height and organically combine various factors observed by their eyes in the current scene. This process needs conception, thinking, aesthetic foundation and the soul of a photo, which is completely completed in the early stage. The later works optimize the photos on the basis of the previous works, and use software tools to make the photos look better. The conception and conception of photos are completed in the early stage, further beautification, rendering and later completion. Therefore, most of the later work is only auxiliary work, but the "degree" of this auxiliary work is difficult to grasp.

So in this new tutorial, I will tell you how to use various tools in PS software and how they work. Friends have learned how to use tools, can freely play in their own photos, how to adjust what they think is beautiful, how to adjust, and make adjustments that they think are "reasonable" according to their personal aesthetic preferences. What is reasonable here is the degree mentioned above.

If the works of photography exhibition are made out of nothing, it is necessary to visualize the observed scenery and form two-dimensional photos, so this is a process of making things out of nothing. Then the later work is the icing on the cake. Attention should be paid to light and shadow, color, composition, perspective, depth of field, contrast and other issues in the early shooting, which will be simplified later. Simply put, for the later software, the basic adjustment of photos can be divided into two parts. Exposure and color. It involves two knowledge points: light and color, which can be combined into RGB, scientific name: three primary colors of color and light. Look at this name, it has light and color.
