Whenever we talk about the concepts of lights and lots of tension into mind, we talk about the intensity of light, we talk about the color temperature of light, we talk about the direction, we talk about the quality, and last but not least we talk about the reflection. So we need to understand these concepts of light, which are quite essential for photographers who want to create, standing in impactful images in the studio, outside the studio, wherever it is you find yourself. By mastering these concepts of photographers, can manipulate, light to achieve their desired effect and tell a story to their images. I built a set of my studio, I shot it behind the scenes, I want to use the concept of light and explain how I got the D-Short. So I used four light and four this particular shoot, one in my 54x72 inch rectangular lags, one in my imbue to this, and two in-ship box. So the deep piece is under the lags balance of the box, the 80-600, and my built to this, and one 80-100 behind the backdrop in the strip box, and the Godog's V-A60-MakTV, in the other strip box on the right side of the arm model. When we talk about intensity, intensity refers to the amounts of light that is present. And photography intensity is probably measured using exposure, which is determined by the combination of aperture, shutter speed, and ISO. So even I have that, and I know the kind of light or feel I want on my subject, I wanted to use both hair light and rim light and layered light and in my shoot. When layered light and came in here by using the beauty of this light in front of my lags balance of the box, the hair light and was being done by hitting the strip box behind the backdrop onto my ceiling just so that it could get soft and even light on my subject, and on the head of my subject, and on the right side you could probably see we have another strip box rimming my subject from the background. The color temperature will probably refer to the color of the light. Light contains from red to blue, depending on whatever I choose you shooting, and taking a look at the search you build, it also affects the kind of mood in the kind of colors you're going to see on my images. The direction of the light will probably also be effective in here also, so as you can see, it can see the position of my light. At some points I moved my beauty to the side of my subject, and I shot opposite of it just to create another mood or dramatic effect from it. The quality of the light will probably refer to how soft or how hard the light will be, so looking at this image the only hard source of light was coming in from my beauty. The beauty of this represents both soft and hard light, so it's a contrast between the two. The big box was filling in, my shadows just to give me a soft feel. Bouncing their headlights or their back lights onto my ceiling was also to introduce a quality of a soft light onto the back of my head or the head of my subject, which probably was covered with the hat, and using the strip box on my right side was to cut out my subject from the background.
