Weekly Vocab

1.

: Macro photography is a type of close-up photography that involves capturing images of small subjects at a very close range. In macro photography, the subject is typically photographed at a magnification ratio of 1:1 or higher, allowing for intricate details to be captured in the image. This type of photography requires specialized equipment such as macro lenses or extension tubes to achieve high levels of magnification.

2.

: Working distance refers to the distance between the front of the lens and the subject being photographed in macro photography. It is important in macro photography as it impacts the composition of the image and the amount of light that reaches the subject. Different lenses have varying working distances, with longer working distances providing more space between the lens and the subject, which can be beneficial when photographing shy or easily disturbed subjects. 3.

: Focus stacking is a technique used in macro photography to achieve a greater depth of field in the final image. In macro photography, the depth of field is often very shallow due to the close proximity of the camera to the subject. Focus stacking involves taking multiple images of the same subject at slightly different focus points and then combining these images using specialized software to create a final image where all parts of the subject are in sharp focus. 4.

: The reproduction ratio in macro photography refers to the ratio of the size of the subject on the camera's sensor to its actual size in real life. For example, a reproduction ratio of 1:1 means that the subject is reproduced on the camera sensor at its actual size. Higher reproduction ratios, such as 2:1 or 3:1, indicate greater magnification of the subject in the final image. 5.

: Optical anomalies in macro photography refer to aberrations or distortions that can occur in the image due to the characteristics of the lens or the shooting conditions. Common optical anomalies in macro photography include chromatic aberration, spherical aberration, and distortion. These anomalies can affect the sharpness, color accuracy, and overall quality of the image and may require post-processing techniques to correct.
