What are the main things in photography?

As a photographic artist, your knowledge and awareness of these different elements can be vital to the success of your composition and help convey the meaning of your photograph. The exhibition is determined by three essential elements that we will analyze individually here. The aperture is the setting that controls the size of the aperture of the light that reaches the lens. Normally, this is done by controlling the aperture blades, which can be changed to allow the opening to become smaller, where less light passes through, or obviously larger when more light is allowed to pass through.

Openness is also one of the most critical aspects of the approach. A large depth of field, necessary when photographers want to focus as much of the photograph as possible, such as landscape photography, requires a minimum possible aperture (high number). This allows foreground and background objects to be in focus. Obviously, the opposite is true, since to achieve a low depth of field, where a particular point is in focus and the other parts of the image are blurred, a low f-stop (low number) must be used.

This creates the beautiful bokeh effect that we love, which adds dramatic effects to images where you want to highlight an object or subject, such as macro photographs and portrait photographs. The fact that you can post-process this effect using Photoshop or similar software today is regrettable, but it shows the popularity it has gained. The ISO is a little less obvious than the previous two in terms of what it is and what role it plays, but it is just as important in determining the correct exposure. The ISO is normally measured from 100, 200, 400, etc.

This is because the higher the ISO used, the more “noise” you get in an image, as the image is not as sharp as in the lower ISOs. In short, sometimes it's not possible, especially in difficult conditions, such as low light. Increasing the ISO may allow you to get images that you wouldn't normally get, but at an additional cost, noise, if you just want to capture the scene and focus precisely, is a secondary idea, then increasing the ISO is an option. When you use a higher ISO, you increase the sensitivity of the image sensor, so the sensor now captures not only more incoming light, but also more ambient noise, reducing image clarity.

Know Why You're Photographing Even if you're flavoring without a definite image in mind, you're still coming out with a camera and a purpose. The objective here would be to observe, write down things that are different or exceptional and record them. This leads to a kind of mental healing and observation before you even turn on the camera; you're already pre-selecting and evaluating the scene in your subconscious before trying to isolate and record it. There is a purpose, and that purpose guides coherence.

If you can't slow down the shutter speed due to motion blur and the tripod isn't an option, it's better to get a sharp photo with a little noise than not to take any photos, and you'll be able to eliminate a lot of noise in post-processing anyway. In addition, camera technology has improved so much in recent years that it is now quite possible to produce incredible photographs even with ISO 1600, 3200, 6400 or higher. Once you start shooting in RAW, post-processing will become essential and not last-minute, so you'll have to invest in photo editing software that allows you to perform basic editing tasks, such as cropping, adjusting exposure, white balance and contrast, eliminating imperfections and much more more. This basic photography guide is what I would have loved to find when I first picked up the camera; all the important information you need to understand the main concepts of photography shown in a logical and digestible order.

Just as a carpenter uses a hammer, the camera, lenses and other equipment are his main tools for creating images. When shooting portraits, whether of people or animals, the subject must be the main focus of the image and the best way to achieve this is to use a wider aperture. You can see all the main effects of this exposure setting in the following basic photo cheat sheet for aperture. You can see some examples in the following basic infographic on photography related to the measurement modes of the main camera.

In general terms, the background should be as simple and tidy as possible so that it does not distract the viewer's attention from the main subject of the photo. Simply put, camera modes are the camera controls that allow the photographer to choose the main exposure settings for aperture, shutter speed and ISO. The exposure triangle is included in most of the initial photo guides and is simply an analogy to explain the effects and interaction of the main basic concepts of exposure in photography. However, things aren't easy when you start; what are the basics of photography? What are the fundamental concepts of digital photography? What's the best way to learn the basics?.

Regardless of your interests, equipment, or objectives, having a solid foundation of the main concepts of photography is key to capturing better images and improving your photography. . .
