Macro Lens  A macro lens is a specialized type of camera lens designed for close-up photography, enabling photographers to capture highly detailed images of small subjects at close distances with high magnification. Macro lenses are characterized by their ability to focus sharply on subjects at extremely close range, often with a reproduction ratio of 1:1 or greater, where the subject appears life-size or larger on the camera's image sensor.

Macro lenses feature optical designs optimized for close focusing distances, minimal distortion, and high resolving power, allowing photographers to capture intricate details, textures, and patterns that are not visible to the naked eye. Macro lenses are commonly used in various genres of photography, including nature photography, product photography, scientific imaging, and fine art photography, where capturing small subjects with exceptional detail and clarity is paramount.
Macro Photography  Macro photography is a genre of photography that focuses on capturing extreme close-up images of small subjects, revealing intricate details, textures, and patterns that are often overlooked by the naked eye. In macro photography, photographers use specialized equipment such as macro lenses, extension tubes, or close-up filters to achieve high magnification and sharp focus at close distances.
Common subjects for macro photography include flowers, insects, plants, textures, and everyday objects, where the emphasis is on exploring the beauty and complexity of the subject up close. Macro photographers often employ techniques such as shallow depth of field, selective focus, and careful composition to isolate the subject from the background and create visually compelling images that evoke a sense of wonder and fascination. Macro photography requires patience, attention to detail, and a keen eye for composition, as well as an understanding of lighting, depth of field, and focusing techniques to achieve stunning results.
Magnification  Magnification in photography refers to the degree to which a subject appears larger in the final image compared to its actual size in real life. Magnification is determined by the focal length of the lens, the distance between the camera and the subject, and the size of the camera sensor or film frame. In macro photography, magnification is a critical factor in capturing highly detailed images of small subjects at close distances.

Magnification ratios, often expressed as fractions (e.g., 1:1, 1:2, 1:3), indicate the relationship between the size of the subject in the final image and its actual size in real life. A magnification ratio of 1:1 means that the subject appears life-size on the camera's image sensor, while higher magnification ratios (e.g., 2:1, 3:1) indicate greater enlargement of the subject relative to its actual size. Magnification is a key consideration for photographers when choosing lenses and camera setups for macro photography, as it directly influences the level of detail, depth of field, and composition of the final image.
Manual Focus  Manual focus is a camera focusing mode that allows photographers to manually adjust the focus of the lens by rotating the focus ring until the desired subject appears sharp and in focus through the camera viewfinder or LCD screen. Unlike autofocus systems, which rely on motorized mechanisms and electronic sensors to automatically detect and adjust focus, manual focus gives photographers full control over the focusing process, allowing for precise adjustments and creative freedom.
Manual focus is particularly useful in situations where autofocus may struggle to accurately lock onto the desired subject, such as low-light conditions, fast-moving subjects, or scenes with complex compositions. Many modern digital cameras feature manual focus assist tools, such as focus peaking and magnified view, which help photographers achieve precise focus by highlighting sharp edges and fine details in the image. Manual focus is also favored by photographers working with macro lenses, tilt-shift lenses, and manual focus prime lenses, where critical focus and depth of field control are essential for achieving optimal image quality and creative expression.
Manual Mode  Manual mode is a camera setting that allows photographers to have full control over exposure parameters such as aperture, shutter speed, and ISO sensitivity. In manual mode, the photographer manually selects each of these settings based on the desired creative outcome and the prevailing lighting conditions. Unlike automatic or semi-automatic shooting modes where the camera's exposure metering system determines the optimal exposure settings, manual mode puts the photographer in complete control, allowing for precise adjustments and creative flexibility.

Manual mode is particularly useful in situations where the lighting is constant, and the photographer wants to maintain consistent exposure settings across multiple shots or when using external light meters for precise exposure measurements. Using manual mode requires a good understanding of exposure fundamentals and the relationships between aperture, shutter speed, and ISO sensitivity to achieve proper exposure and desired creative effects.
Masks  In digital image editing software such as Adobe Photoshop, masks are used to selectively apply adjustments, effects, or transformations to specific areas of an image while leaving other areas unaffected. Masks work by defining a grayscale layer that determines the opacity of the applied adjustments or effects. White areas of the mask indicate full opacity, where adjustments are fully applied, while black areas indicate transparency, where adjustments are hidden.

Shades of gray represent varying levels of opacity, allowing for smooth transitions between affected and unaffected areas. Masks can be created and edited using selection tools, painting tools, or predefined adjustment layers, providing photographers and digital artists with precise control over image editing and retouching workflows. Common uses of masks include selective adjustments to exposure, color, contrast, sharpening, and retouching of specific elements within an image, such as skies, faces, or objects.
Mat Offset  Refers to the measurement subtracted from the artwork size (width and height) to allow for the mat to overlap the image. Generally, 1/4" is subtracted from each measurement, for an overlap of 1/8" on each side. Mat Offset
Mat(ting)  A thin, flat, paper-based board (sometimes called a "mat board")used in picture framing to separate the artwork from the glass. A window is cut into the center of the mat board, usually in a rectangle that covers the piece 1/8" on each side, creating a border around the artwork. The mat border also serves as a distraction-free "breathing space" between image and frame.

Matte Finish  A non-glossy, "flat" finish that creates an even reflective surface with no glare. Matte paper is generally smooth in texture.
Maximum Aperture  The maximum aperture of a lens refers to the widest opening of the lens diaphragm, expressed as the smallest f-stop number (e.g., f/1.8, f/2.8). The maximum aperture determines the amount of light that can pass through the lens to the camera sensor and influences several aspects of photographic performance, including exposure, depth of field, and low-light capabilities. Lenses with larger maximum apertures allow more light to reach the sensor, enabling faster shutter speeds and better performance in low-light conditions.
Additionally, larger apertures result in shallower depth of field, allowing photographers to isolate subjects from the background and create pleasing bokeh effects. Maximum aperture is an important consideration when choosing lenses for specific types of photography, such as portrait photography, where fast lenses with wide maximum apertures are preferred for their ability to create soft, blurred backgrounds and capture sharp, well-exposed images in low light.
Medium Format  Medium format refers to a type of photographic format characterized by larger film or digital sensors compared to standard 35mm film or full-frame digital sensors. Medium format cameras and film formats typically use larger image sensors or film frames, resulting in higher resolution, better image quality, and increased detail compared to smaller formats. Medium format cameras are widely used in professional photography and studio work, where image quality and resolution are paramount, such as fashion photography, commercial advertising, and landscape photography.

Medium format systems offer greater dynamic range, smoother tonal transitions, and superior color reproduction compared to smaller formats, making them ideal for capturing fine details and nuances in texture and tone. While medium format equipment is larger, heavier, and more expensive than smaller format counterparts, the benefits of medium format photography include unparalleled image quality, versatility, and creative potential for photographers seeking the highest level of performance and fidelity.
Medium Format Camera  A medium format camera is a type of camera that uses a medium format film or digital sensor to capture images. Medium format cameras are characterized by their larger image sensors or film frames compared to standard 35mm film or digital full-frame sensors, resulting in higher resolution, better image quality, and increased detail. Medium format cameras come in various configurations, including modular systems with interchangeable backs, rangefinder-style cameras, and digital medium format cameras with electronic viewfinders and autofocus capabilities.

Medium format cameras are widely used in professional photography and studio work, where image quality and resolution are critical, such as fashion photography, commercial advertising, and landscape photography. Medium format systems offer superior dynamic range, smoother tonal transitions, and finer detail compared to smaller format cameras, making them ideal for capturing the subtle nuances and textures of the subject with exceptional clarity and fidelity. While medium format cameras are larger, heavier, and more expensive than smaller format counterparts, they offer unmatched image quality, versatility, and creative potential for photographers who demand the highest level of performance and precision in their work.
Medium Format Sensor  A medium format sensor is a type of image sensor used in digital cameras, characterized by its larger size compared to sensors found in standard full-frame or APS-C format cameras. Medium format sensors offer significantly higher resolution and better image quality due to their larger surface area, which allows for capturing more detail and capturing light more effectively. The dimensions of medium format sensors vary depending on the specific camera model and manufacturer, but they typically exceed the dimensions of full-frame sensors, which are themselves larger than APS-C or Micro Four Thirds sensors.
Medium format sensors are commonly used in medium format digital cameras designed for professional photography, such as studio work, fashion photography, landscape photography, and commercial advertising. The larger sensor size of medium format cameras results in images with greater dynamic range, smoother tonal transitions, and exceptional detail, making them preferred tools for photographers who prioritize image quality and require high-resolution output.
Megapixel  A megapixel is a unit of measurement used to quantify the resolution of digital images, representing one million pixels. It is commonly used to describe the resolution capability of digital cameras, camera sensors, and digital displays. The number of megapixels in an image indicates the total number of individual pixels that compose the image, with higher megapixel counts corresponding to higher image resolutions and potential for finer detail and larger print sizes.
For example, an image captured by a camera with a resolution of 12 megapixels contains approximately 12 million pixels, while an image captured by a camera with a resolution of 24 megapixels contains approximately 24 million pixels. The megapixel count alone does not determine image quality, as factors such as sensor size, pixel size, lens quality, and image processing also play significant roles. However, higher megapixel counts generally allow for greater flexibility in cropping, printing large-format images, and capturing finer details, particularly in situations where high-resolution output is desired.
Memory Card  A memory card is a portable storage device used to store digital data, such as photographs, videos, audio files, and documents. Memory cards are commonly used in digital cameras, camcorders, smartphones, tablets, and other electronic devices that require removable storage for capturing and storing multimedia content. Memory cards come in various formats and capacities, including Secure Digital (SD), CompactFlash (CF), microSD, Memory Stick, and others, each with its own physical size, storage capacity, and data transfer speed.

The storage capacity of memory cards ranges from a few gigabytes to several terabytes, allowing users to store thousands of photos, hours of video footage, and large data files. Memory cards are designed to be durable, shock-resistant, and capable of withstanding extreme temperatures and environmental conditions, making them suitable for use in demanding situations such as outdoor photography, sports photography, and professional videography. When choosing a memory card, factors to consider include storage capacity, data transfer speed, compatibility with the device, and reliability for long-term storage and data retention. Regular backup and proper handling of memory cards are essential to prevent data loss and ensure the integrity of stored digital content.
Metadata  Metadata refers to descriptive information embedded within a digital file that provides details about its content, creation, and other relevant attributes. In the context of digital photography, metadata typically includes information such as the camera settings used to capture the image (e.g., aperture, shutter speed, ISO sensitivity), the date and time the image was taken, the camera model, lens information, GPS coordinates (if available), copyright information, and other relevant details.
Metadata serves several purposes, including organizing and cataloging images, providing context for understanding the content and context of the image, facilitating image retrieval and search, and ensuring proper attribution and copyright protection. Metadata can be viewed, edited, and managed using various software applications and digital asset management systems, allowing photographers to add, modify, or remove metadata as needed to organize and manage their digital image libraries effectively.
Midtone Clipping  Midtone clipping, also known as midtone loss or midtone compression, refers to the loss of detail and tonal information in the midtone regions of an image caused by overexposure or underexposure during image capture. Midtones represent the middle range of tonal values in an image, spanning from shadows to highlights, and are crucial for preserving detail and contrast in the image. When midtone clipping occurs, areas of the image that should display subtle tonal variations and texture appear flat, lacking detail and dimension.

Midtone clipping often occurs in high-contrast scenes with harsh lighting or when the dynamic range of the scene exceeds the capabilities of the camera sensor to capture detail in both shadows and highlights. To mitigate midtone clipping, photographers can use exposure compensation, graduated neutral density filters, or bracketing techniques to capture multiple exposures and blend them together in post-processing. Additionally, careful metering and exposure adjustment can help preserve detail in the midtone regions and ensure optimal image quality.
Minimum Aperture  The minimum aperture of a lens refers to the smallest opening of the lens diaphragm, expressed as the highest f-stop number (e.g., f/16, f/22). The minimum aperture setting determines the least amount of light that can pass through the lens to the camera sensor and influences several aspects of photographic performance, including depth of field, diffraction, and exposure control. Lenses with smaller maximum apertures have greater depth of field, meaning that more of the scene will be in focus from near to far.

This is particularly useful in landscape photography or when photographers want to ensure that all elements of the scene are sharp and in focus. However, smaller apertures also result in reduced light transmission, which can necessitate longer exposure times or higher ISO settings to achieve proper exposure. Additionally, extremely small apertures can lead to diffraction, where light rays are bent as they pass through the aperture, causing a loss of image sharpness and detail. Understanding the effects of minimum aperture settings is important for photographers when selecting aperture values to achieve the desired depth of field and image quality in their photographs.
Minimum Focus Distance  The minimum focus distance is the closest distance at which a camera lens can focus on a subject while still producing a sharp image. Every lens has a minimum focus distance, which is typically indicated on the lens barrel or specified in the lens specifications. The minimum focus distance varies depending on the lens design, focal length, and maximum aperture. For macro lenses or lenses designed for close-up photography, the minimum focus distance may be very short, allowing the lens to focus on subjects that are just a few centimeters away from the front element.

In contrast, telephoto lenses may have longer minimum focus distances, requiring the photographer to be farther away from the subject to achieve sharp focus. Understanding the minimum focus distance of a lens is important for photographers, especially when shooting close-up subjects or when working in confined spaces where the ability to focus at close distances is crucial.
Mirrorless Camera  A mirrorless camera is a type of digital camera that does not use a reflex mirror, as found in traditional DSLR (Digital Single Lens Reflex) cameras, to reflect light from the lens into an optical viewfinder. Instead, mirrorless cameras use a digital display, such as an electronic viewfinder (EVF) or a rear LCD screen, to provide a real-time preview of the image as captured by the camera sensor.
Mirrorless cameras are characterized by their compact and lightweight design, as well as their versatility and advanced features, including interchangeable lenses, electronic viewfinders, and advanced autofocus systems. Without the mirror mechanism found in DSLR cameras, mirrorless cameras can be made smaller and lighter while offering comparable image quality and performance. Mirrorless cameras are popular among photographers and videographers for their portability, silent operation, and ability to adapt to various shooting situations and creative styles.
Moiré  Moiré is an interference pattern that occurs when two sets of repeating patterns, such as lines or grids, overlap or are slightly out of alignment with each other. In digital imaging, moiré patterns can occur when photographing subjects with fine, repetitive textures or patterns, such as textiles, screens, or architectural details. Moiré patterns appear as unwanted visual artifacts or shimmering effects in the final image, caused by the interaction between the repeating patterns in the subject and the grid-like arrangement of pixels on the camera sensor.

Moiré patterns are more likely to occur in digital images captured by cameras with lower resolution sensors or when photographing subjects with high spatial frequency patterns. To mitigate moiré patterns, photographers can adjust the shooting angle, change the distance from the subject, or use anti-aliasing filters in front of the camera sensor to blur fine details and reduce the likelihood of interference patterns. In post-processing, moiré patterns can be corrected using specialized software tools or by applying selective blurring or sharpening techniques to affected areas of the image.

In post-processing, moiré patterns can be corrected using specialized software tools or by applying selective blurring or sharpening techniques to affected areas of the image. Understanding the causes and characteristics of moiré patterns is important for photographers to minimize their occurrence and preserve image quality in digital photography.
Monochrome  Monochrome refers to images that are composed of varying shades of a single color, typically black, white, or grayscale. In photography, monochrome images lack color information and are represented solely by variations in brightness and contrast. Monochrome photography emphasizes shape, form, texture, and tonality, allowing photographers to convey mood, atmosphere, and emotion through the interplay of light and shadow.
Common techniques for creating monochrome images include converting color photographs to grayscale or shooting with black-and-white film. Monochrome images often evoke a timeless and classic aesthetic, and they are widely used in fine art photography, portrait photography, street photography, and documentary photography to capture the essence of a subject without the distraction of color.
Monopod  A monopod is a single-legged camera support device used to stabilize and steady a camera while shooting handheld. Similar to a tripod but with only one leg, a monopod helps reduce camera shake and allows photographers to achieve sharper images, especially in low-light conditions or when using telephoto lenses with long focal lengths.

Monopods are lightweight, portable, and easy to set up, making them ideal for photographers who need to maintain mobility while shooting, such as sports photographers, wildlife photographers, and photojournalists. By providing a stable platform for the camera, monopods help photographers capture sharp and steady images while reducing fatigue during extended shooting sessions. Some monopods feature adjustable height and tilt, allowing photographers to customize the angle and composition of their shots with ease.
Motion Blur  Motion blur refers to the streaking or smearing effect that occurs when moving subjects or camera motion is captured during a photographic exposure. Motion blur can occur intentionally or unintentionally and can add a sense of dynamism, speed, and energy to an image, or it can result in undesirable blurring and loss of detail. Intentional motion blur is often used creatively by photographers to convey a sense of movement or action, such as panning shots of moving subjects, long exposure shots of flowing water or traffic, or intentionally blurred backgrounds to isolate the subject.
Unintentional motion blur may occur when the camera is handheld at slow shutter speeds, when the subject moves unexpectedly during the exposure, or when the photographer fails to track moving subjects accurately. Techniques for minimizing motion blur include using faster shutter speeds, stabilizing the camera with a tripod or monopod, using image stabilization technology, and anticipating the movement of the subject to ensure sharp focus and clear detail in the final image.
Mounting  Mounting refers to the process of attaching or securing a print, artwork, photograph, or other two-dimensional object onto a backing board, mat, frame, or display surface for presentation, protection, or preservation. Mounting techniques vary depending on the size, weight, and characteristics of the object being mounted, as well as the desired display method and aesthetic preferences.

Common mounting methods include dry mounting (using adhesives or heat to bond the print to a backing board), hinge mounting (attaching the print to a mat or backing board using archival hinges), float mounting (suspending the print within a frame or display case), and pressure-sensitive mounting (using adhesive sheets or tapes to adhere the print to a substrate). Proper mounting ensures that prints are securely held in place, flat, and protected from damage or deterioration over time.
Museum Wrap  While "gallery wrap" refers simply to the process of wrapping a canvas all the way around the stretcher bar frame and affixing it to the back, "Museum wrap" refers to the color on the drop edges (sides) of the canvas). In a museum wrap, the entire image is confined to the front of the canvas, and the sides are a solid color or white. This may be due to canvases in museums and galleries generally being frames, so the edges were never visible.

There appears to be some disagreement about whether museum wrap is limited to canvases wrapped on 1 1/2" in stretcher bars, or if the depth of the bar does not matter for the designation.
