Where do you focus in a group photo?

For group portraits, avoid placing the focus point on someone that’s towards the edges of the frame. The sharpest focus comes from the centre focal points. If you have a group of two rows or less, place the focal point on the face of a person towards the centre of the first row.

Should I use AF or MF?

Re: When to use MF vs AF? use MF when your subject is has nothing between you and the camera. AF requires your subject be covered by an AF area, which are large-ish groups of pixels. It’s common for AF to focus on objects you don’t want but which are inside the focus area, even if the subject is also in the focus area.

What is the difference between AF S and AF C?

AF-C (AF-continuous or servo mode) is used for photographing moving subjects. AF-S means single shot and is used for subject that is stationary. AF-A is where the camera decides whether the subject is moving or not and tries to alternate between the servo and single shot mode accordingly.

Is 9 AF points enough?

Multi-Point AF with fewer points: This mode (activating 9 or 11 points, depending on the camera) should provide faster, more reliable AF with an erratically moving bird since the camera needs to process less data from the fewer points. Most of the expert bird photographers I have worked with recommend this option.

Do more megapixels mean better photo quality?

Why More Megapixels Is Better The higher the megapixel count on a camera sensor, the greater amount of detail that can be captured in a picture. For instance, a 6MP sensor captures roughly fifty percent more detail in an image than a 4MP sensor and double what a 3MP sensor has and four times that of a 1.5MP sensor.

What is full time servo AF?

In full-time servo AF (AF-F), the camera continuously adjusts focus in response to changes in the distance to the subject in the selected focus area until the shutter-release button is pressed halfway to lock focus. During movie recording, the camera continuously maintains focus on the subject in the focus area.

Should you use autofocus or manual?

Autofocus is generally faster and easier than setting the focus manually. It can lock onto a subject faster, as well. This makes it suitable for shooting moving subjects. If you’re doing street photography, for example, you could only have seconds to capture your subjects.

How does continuous autofocus work?

In continuous AF (Ai Servo AF for Canon), once you lock focus on a stationary subject the camera will do its best to follow your subject keeping them in focus. The camera detects the movement of your subject and refocuses constantly to keep it in focus as long as you are pressing the shutter halfway.
