SLR camera simulator. From virtuality to reality

A virtual camera simulator is a photographer's simulator that allows you to easily and accurately learn the relationships between the lens, aperture and ISO. With Vikorist’s virtual simulator as a photographer, you can easily figure out how to adjust the aperture to the depth of sharpness and exposure, and how to adjust the exposure and blur of the image. In addition, this camera simulator can be used to experiment with camera settings both in manual mode and in the modes of aperture and aperture priority.

Short instructions for setting up a virtual camera

Aperture - Aperture

Aperture (aperture) - a light-impermeable partition installed between the objective lenses. The aperture adjusts the opening at the center to transmit a beam of light from the subject to the camera matrix. The depth of sharpness changes depending on the size. The larger the aperture opening, the less. In addition, the size of the aperture opening influences the exposure of the frame - the larger the aperture, the more light passes to the matrix (or the film).

To change how the diaphragm works, move the motor Aperture Be careful of changes in the depth of sharpness and brightness of the photo. Above the engine there are digital aperture values, which indicate the size of the aperture opening, indicated for a small right-handed device.

Shutter - Shutter

Shutter (shutter) - adjusts the exposure of the photo. The longer the shutter curtains are open (longer window), the more light will be transmitted to the matrix. Move the engine Shutter And be careful how the brightness of the picture changes depending on the amount of shading indicated above the engine. In the picture, right-handed, you can see how the shutter operates at specific values ​​of the shutter - press the button test speed.

When taking photos in manual mode, it is most important to know that the aperture and window settings are used to ensure that the frame appears with normal brightness.

When choosing a display, make sure that the display can bring you up to the objects that are especially crumbling, for example, a dog in the foreground that will run up to the eye.

ISO – matrix sensitivity

In the case where the range of windows and apertures of your camera does not allow you to retain the normal brightness of the frame, you need to change the sensitivity of the matrix - Restore the fact that at high ISO values ​​the photos appear color dots

Light meter - exposure meter

Almost all digital cameras use a photoexposure meter. Light meter(Light meter). The exposure meter is an electronic device for adjusting the brightness of the photographed object. In many cameras, the exposure meter operates simultaneously with the exposure indicator. The exposure indicator on the photographer’s simulator is a scale under the picture frame. Just like in a real digital camera, it shows how many steps the photographer sets, the exposure is adjusted according to the camera’s automation.

Link Aperture / Shutter - A(Av)/S(Tv) mode

Switching the camera simulator to automatic

The aperture priority mode is indicated by Av or A and is selected for the camera. The photographer sets the required depth of sharpness (lens aperture), and the camera automatically adjusts the appropriate lighting for shooting, when The aperture value has already been set by the photographer.

The display priority mode is set to S or TV and works the same way as the aperture priority mode, but now the photographer sets the display, and the camera adjusts this setting and automatically selects the required aperture.

Thus, in priority modes, the aperture and windshield are linked to one of the camera’s controls and are subject to the settings selected by the photographer. That’s why such modes are called automatically. It’s easy to point out that the photographer doesn’t have enough information, or it just doesn’t take a lot of time to install through the window, and then the diaphragm.

Link Aperture/Shutter[Link aperture and aperture] - if you want to switch to automatic priority mode, then on the camera simulator, put a cross next to this box. Now, when you change the aperture, the aperture values ​​change automatically, and when you change the aperture, the aperture automatically changes. So the interaction is equivalent depending on which engine of the camera simulator you use (Aperture or Shutter), the virtual simulator has a mode of either Vibration Priority or Aperture Priority, respectively.

The lens aperture controls the opening through which images are projected onto the camera sensor. The smaller the aperture number, the larger the opening and the more light is transferred to the light-sensitive element.

For example, if the camera shoots at F/5.6, it captures less light than at F/2.0. An F/1.8 lens can be called “bright”, the brighter the lens is, the better it is for capturing poorly lit scenes. Therefore, choose a camera with the lowest aperture number (F/1.8 is higher, lower than F/2.8).

For cameras with a zoom lens, for example 18-55 mm, you most often select two pairs of numbers, for example f/3.5-5.6. This is called an interchangeable diaphragm. The first aperture number means the maximum aperture when taken at the widest possible focal length, the minimum focal length is 18 mm, and another meaning is to talk about the maximum aperture when taken at the maximum focal length - 55 mm. When scaling or changing the focal length, the aperture also changes.

It is also important to note that in cameras with large sensors, the aperture value affects the level of sharpness. So, with a large aperture, you can remove a small depth of sharpness, thus creating a beautiful background, so-called “bokeh”. Unfortunately, it is practically impossible to remove such an effect with a small sensor.

Vitrimka

The hour during which the camera shutter is open and light is shining on the sensor (light-sensitive element) is called exposure. For example, 1/60 of a second – long winding – more, lower 1/2000 – short winding. The more light you have on the screen, the more light you have on the sensor.

The diaphragm and the windshield are closely interconnected with each other and are called “expocoupler”. With a short exposure time, photographs can come out underexposed - too dark, and with a long exposure - overexposed - too light or blurred through a three-dimensional camera, if taken by hand.

Light sensitivity (ISO)

The higher the sensitivity of the camera sensor, the higher the sensitivity of the sensor. For example, a camera sensor at ISO3200 is sensitive to light, less sensitive at ISO200, which allows you to take a frame in the absence of insufficient light, and at which point the pixels are more intense and the result of the photo is “bright” imaginary" or "grainy", which appears in the appearance of different colored dots. scattered throughout the entire frame.

Exhibition

Visibility, aperture and light sensitivity are the three main elements that need to be corrected, adjusted and exposure. This is the title of trikutnik of exposition. The exposure comes out of the interaction of these three elements and is located in the middle of the tricubitule.

The most important are those that all elements interact strongly with each other.

Understanding the interaction between windshield, aperture and ISO requires consistent practice. Much of it is based on intuition and luck, and most experienced photographers can adjust their camera on their own, without having to worry about all the options. Please note that changing the skin element does not only affect the change in the exposure of the image, but also other moments in the photograph. For example, changing the aperture, changing the depth of sharpness - the smaller the opening, the greater the depth of sharpness. A high ISO will add noise, and long exposure to hand-held motion will result in blurred images.

If you already have a SLR camera, and you only use it in “automatic” mode, if you were a high school miler, then you are spending a lot! The time has come to find out about all the capabilities of your DSLR. Here you can play with visibility, aperture, light sensitivity and be careful how these parameters affect the final result.

If you have never used a SLR camera before, or only bought one and want to try taking photographs in manual mode, then you will not want to practice on the simulator. With this online SLR camera simulator you can try virtual photography. All necessary settings for recording are available. We will help you quickly learn the basic adjustments of a SLR camera, such as brightness, aperture, ISO, focal length, etc.

Managing a virtual camera:

Lighting:

Lighting is the most important factor, which means your camera needs to be brightened. There are also some important moments, if there is too much light in the frame, then it’s bad - even the frame will be overexposed. Vikorist this step for adjusting the camera under the song of the light source

Vidstan:

Check this step to see how close or far you are to the object.

Focus:

Moving this bar has the same effect as zooming in and out on your lens. at a small focal length of 18 mm there will be a greater focus and more objects will be captured in the frame, and a higher focal length of 50 mm will give a larger frame, which will help you create beautiful portraits in a better way Let's add a background.

Mode:

The exposure mode of a SLR camera allows you to adjust one parameter, while another parameter will be adjusted automatically. So in the aperture priority mode, you set the aperture yourself, and the display is adjusted automatically, and in the display priority mode, everything is the same. Turning to Manual mode (M) allows you to set all settings manually to achieve the desired effect. To ensure the correct exposure, look at the camera's light meter, so the drawing should be in the middle between the two indicators for correct exposure.

ISO:

ISO is adjusted to the light sensitivity of the camera, which indicates how bright the matrix will be. During the day, if the lighting is good, set ISO 100-200, which will give you a clean contrast picture without noise; in the evening, if the light is darker, you will need to set ISO 800 or higher, so that the frame is bright, but in any case At higher ISO levels, the graininess of the frame will increase.

Aperture:

The aperture controls how much light passes through the lens or what effect you want to achieve. If you are shooting a landscape, then for sharpness in every frame you need to set the aperture to 7 and above, if you are shooting a portrait and you want to maximize the background and create it within the frame, then you need to set aperture 2-4. At the same time, in the dark hour, add aperture value 7 to skip 3 times less light, lower value 2.

Vitrimka:

The window indicates how quickly the frame will be shot, and over time the shutter will no longer be able to open. A short-term value of 1/500 s or 1/2000 s allows you to freeze the object of capture. For example, a car that is collapsing, or a man in a haircut. Vitrimka bolsh dovga taka 1/15 sec or 2 sec allow to dissolve the roc. But keep in mind that the shorter the window, the less light it lets in. Then during the day the lighting is 1/15 s to make the frame overexposed, and in the evening 1/2000 s is to make it even darker.

Change the values ​​under the screen and click the “Take photo” button. The result will appear on the screen.

Parameters that are used in the simulator:

Lighting:

Lighting is a major factor in how your camera is installed. Use this tutorial to experiment with different types of lighting. The lack of brightness can be compensated for by higher visibility or wider apertures.

Vidstan:

Check this step to see how close or far you are to the object. The surface infuses a depth of sharpness. By changing the depth of sharpness, you can “blur” objects or the background or give your photo high clarity.

Focus:

The focal length determines the boundaries of the frame and the field of view of the lens. The greater the focal length, the smaller the angle (the lens covers a smaller portion of the frame), the larger the subject of the photograph in the frame.

By moving left-handed to a wide angle, you will not only create the greatest depth of sharpness (a clearer shot), but will also add more field to the frame. By moving the slider right-handed, you create a smaller depth of sharpness (as long as the main subject is in focus).

Winter modes:

Exposure modes from DSLR cameras allow exposure to one parameter, while the camera automatically adjusts others.

In the privacy priority mode, set the shutter speed. The camera can set the aperture on its own. In Aperture Priority mode, set the aperture, and set the camera to visor.

In manual mode, you independently set the values ​​of visibility and aperture. Scroll down to the camera exposure meter below the images. This allows you to select the correct exposure.

Tripod:

A flexible tripod in many situations allows you to experience the “shaking” effect and capture clearer images.

ISO:

ISO – lightness of the matrix and casting. ISO is one of three parameters that influence exposure, including the aperture and aperture.

The lowest ISO (100 in the simulator) allows you to capture a cleaner image, without noise. However, it benefits from a greater amount of light – long exposures or an open aperture (smaller aperture values, for example, 2.8).

At high ISO values ​​(often above 400 or 800), noise can appear in the image, which can detract from the brightness of the image.

Aperture:

The aperture determines the amount of light that passes through the lens and hits the matrix (or film).

With changes in the value of f, the size of the lens aperture increases and, apparently, the amount of light that falls on the matrix (or melt).

Also, the size of the aperture effectively affects the part that is not at the focus of the lens. With small aperture values, the background blur effect often occurs.

Vitrimka:

The window lasts for an hour, as long as the shutter is open. An hour of light is spent on the matrix (or spitting) which creates the image.

High shutter speeds allow you to “freeze” the color in the photograph, but allow too much light to come out. More fluidity allows you to capture less light, but may cause the image to blur.

Exposure:

For additional exposure, you adjust the amount of light that is applied to the matrix (or melt). Exposure depends on ISO, aperture and window. Click through these parameters and you will be able to understand how stinks affect the exposure.
