How to use manual mode on my DSLR camera?

Posted by Allan Peck on 1 year ago


Using the manual mode becomes extremely easy and fun once you learn about the three main technical aspects of photography: shutter speed, aperture, and ISO; firstly, however, you need to remember that photography is actually light “recorded” on a film or a matrix of a digital camera. If the general amount of light (called exposure) is not sufficient, it will result in a dark photo; in its turn, an over-exposed photo (the one with too much light caught by a film/matrix) will be all white. So, one of the main tasks of a photographer is to find the proper exposure. This is what shutter speed, aperture, and ISO are needed for. Omitting all the technical details, remember that:

- Shutter speed is responsible for whether the moving objects on a photo will be blurred or sharp. The higher the shutter speed (1/30, 1/125, 1/500 and so on), the less the effect of motion blur; high shutter speed, however, makes a photo darker. And on the contrary, the slower the shutter speed (1/20, 1/10, 1 seconds, and so on) the more blurry moving objects will be; a photo, however, will be lighter.
- Aperture is needed to blur the background. Open apertures (f/2.8, f/5.6) are good for making portraits, because they help you to take a clear and sharp shot of a model’s face, while the background will be blurry. Open aperture lets more light get onto the matrix. Closed apertures are good when taking pictures of nature or cityscape, or when you need both background and the foreground to be equally sharp.
- ISO is the sensitivity of a matrix. The higher the ISO value is, the lighter your photo will be; however, mind that high ISO values can negatively affect the overall quality of a photo, making it grainy and “noisy.”

Maintaining balance between these three parameters will help you take good photos.
