If you want to advance as a photographer, you must understand how to use manual mode. If it's too much for you, start with aperture or shutter priority and work your way up. That is, Shutter Priority allows you just control over the shutter speed, leaving you without control over the Depth of Field (DOF) and ISO. Aperture Priority does exactly what it says on the can: It sets the aperture value and lets you adjust other settings like shutter speed or white balance if needed.
In manual mode, you have total control over all aspects of your photo including shutter speed, aperture, and ISO. This mode is useful when you want to capture an image with a specific look in mind. For example, if you want to create a blurry background to fit within the width of a photo album page, you can do that by using a large aperture and a slow shutter speed. The more experienced you become, the more choices you will have in manual mode. For example, if there is a lot of movement in the scene you can use a fast shutter speed to freeze it instead of using a tripod.
Most cameras have a button for switching from auto mode to manual mode and back. You need to press this button repeatedly to switch between the two modes. Some cameras require you to toggle the mode switch manually after each change made in any of the camera settings panels. For example, if you change the shutter speed setting from auto to 30 seconds and back to auto again, you must toggle the mode switch afterward.
Your camera's auto modes (Auto, Program) and semi-automatic settings (Aperture Priority and Shutter Priority) are excellent places to begin. Manual mode will offer you far more control over the appearance of your images. Because manual mode will provide you far more control over the appearance of your images. You can create much more interesting photographs by using this setting.
When should I use auto mode? When shooting in low light conditions or when you don't have time to adjust the settings, your camera may choose an appropriate mode for you. However, if you want complete control over all aspects of your photo, such as being able to adjust the exposure after you take the picture, then manual mode is the way to go.
In actuality, understanding manual mode is not difficult. It's true that it's not for everyone. Many photographers are willing to let their camera choose the best exposure settings for them. "Which parameter should I alter first?" is one of the most typical inquiries I hear from individuals I educate how to utilize manual mode. The answer is simple: both at the same time. If you change the shutter speed without changing the aperture, your photo will be underexposed; if you open up the aperture without adjusting the shutter speed, your photo will be overexposed.
The easiest way to understand manual mode is to try it yourself. Set the ISO and white balance values, then use the shutter speed and f-stop numbers as guidelines. You can still take great photos in manual mode, it's just that you have to pay attention to these two factors at all times when taking pictures.
Manual mode is useful when you want to control exactly how much light reaches the sensor. For example, you might want to create a dark room portrait where the only light comes from the person being photographed. Or perhaps you want to shoot some action shots with a fast shutter speed but don't want to risk having the photo taken by surprise by an unexpected bright light source.
In short, manual mode gives you complete control over how your image looks like. It's recommended for experienced photographers who know what they're doing with their equipment.
