Final answer:
The statement regarding the necessity to manually remove blur in autofocus mode is false. Autofocus automatically adjusts the lens to focus the subject, but issues can arise if the camera is too close to the subject. Manual mode requires the photographer to adjust shutter speed and aperture, unlike autofocus which automates the process.
Step-by-step explanation:
The statement that "When you are in autofocus, you have to worry about removing the blur from your picture, as it will not happen automatically" is false. When using autofocus, the camera automatically adjusts the lens to ensure that the subject is in sharp focus. However, it is crucial to make sure that the camera is not too close to the subject, which could prevent the autofocus from achieving a clear image. You will typically press the shutter button halfway to engage the autofocus. If it does not achieve focus, the camera may be too close, or there could be other issues with the autofocus system.
The concept of focusing in photography is related to adjusting the lens' distance from the film or sensor to achieve a clear image. In manual mode, the photographer manually adjusts both the shutter speed and aperture value to control motion blur and depth of field, whereas in autofocus these adjustments may happen automatically based on the camera's sensors and algorithms.
Remember that the lens operates similar to a thin lens in optics, which requires different distances for focusing on near and distant objects. In the case of a distracting background, zooming in on the subject can help reduce distractions and improve focus.
