Photography terms starting with I
Image Sensor: An image sensor is the electronic device in a camera that captures and converts light into digital signals, forming the basis of a digital image.
ISO: ISO, or International Organization for Standardization, is a standard that measures the sensitivity of the image sensor to light. It is used to adjust the camera’s sensitivity to different lighting conditions.
Infinity Focus: Infinity focus refers to setting the lens focus to capture objects at an infinite distance, resulting in sharpness from the subject to the horizon.
Infrared Photography: Infrared photography involves capturing images using infrared light, which is beyond the range of human vision. It creates unique and ethereal images by revealing heat signatures and penetrating atmospheric conditions.
Image Stabilization: Image stabilization is a technology used to reduce camera shake or motion blur, resulting in sharper images. It compensates for small movements by the photographer or vibrations in the camera system.
Intervalometer: An intervalometer is a device or feature in a camera that allows photographers to set timed intervals between consecutive shots, useful for capturing time-lapse sequences or long-exposure series.
Incandescent Light: Incandescent light refers to the light produced by traditional tungsten filament bulbs. It has a warm, yellowish tone and can create a cozy or nostalgic atmosphere in photographs.
Image Overlay: Image overlay is a technique where multiple images are combined or superimposed to create a single composite image. It is often used in post-processing to create double exposures or add creative effects.
Image Resolution: Image resolution refers to the level of detail or clarity in an image, usually measured in pixels per inch (PPI) or dots per inch (DPI). Higher resolution images have more pixels, resulting in sharper and more detailed prints or displays.
Image Noise: Image noise refers to random variations or speckles that can appear in digital images, especially in low-light or high-ISO conditions. It can degrade image quality by reducing sharpness and introducing unwanted artifacts.
Intentional Camera Movement (ICM): Intentional camera movement is a creative technique where the camera is intentionally moved during a long exposure to create abstract and impressionistic images. It results in blurred and dynamic effects.
In-Camera Processing: In-camera processing refers to the ability of a camera to apply various adjustments or effects to an image directly within the camera, without the need for external software or post-processing.
Inverse Square Law: The inverse square law states that the intensity of light decreases in proportion to the square of the distance from the light source. It is important to understand for controlling light and exposure in photography.
Image Histogram: An image histogram is a graphical representation of the distribution of tonal values in an image. It helps photographers analyze the exposure and contrast of an image and make adjustments accordingly.
Interchangeable Lens: An interchangeable lens is a lens designed to be attached and detached from a camera body, allowing photographers to use different lenses for various shooting situations or creative effects.
In-Body Image Stabilization (IBIS): In-body image stabilization is a technology found in some cameras where the image stabilization mechanism is built into the camera body instead of the lens. It provides stabilization benefits with any lens attached to the camera.
Image Editing: Image editing involves modifying and enhancing digital images using software or applications. It includes adjustments to exposure, color, contrast, cropping, and other creative manipulations to improve the visual impact of a photograph.
Instant Camera: An instant camera is a type of camera that produces self-developing prints shortly after capturing an image. It offers immediate gratification and tangible results, reminiscent of the classic Polaroid cameras.
In-camera Multiple Exposures: In-camera multiple exposures is a feature in some cameras that allows photographers to combine multiple exposures within a single frame, creating double exposures or overlaying different scenes for creative effects.
Image Overlay Blending: Image overlay blending is a technique where multiple images are combined using post-processing software, overlaying them to create a blended and cohesive final image. It is often used for creative compositions or exposure blending.
Inverse Lens: An inverse lens, also known as a reverse lens or macro reverse ring, is a technique where a lens is mounted backward on the camera body to achieve extreme close-up magnification. It is a cost-effective alternative to dedicated macro lenses.
In-camera Raw Conversion: In-camera raw conversion allows photographers to convert raw image files to JPEG or other formats directly within the camera, bypassing the need for external software. It provides quick previews or ready-to-use files.
Image Metadata: Image metadata refers to the information embedded in an image file that provides details about the camera settings, date and time of capture, location, copyright information, and other relevant data. It is useful for organizing and categorizing images.
Infrared Filter: An infrared filter is a specialized optical filter that blocks visible light while allowing infrared light to pass through. It is used in infrared photography to isolate the infrared spectrum and create distinctive images.
In-camera Black and White: In-camera black and white mode allows photographers to capture images directly in black and white without converting them in post-processing. It helps visualize the scene in monochrome and emphasizes contrast and textures.
Image Cropping: Image cropping is the process of trimming or removing unwanted parts of an image to improve composition, remove distractions, or create a specific aspect ratio. It can be done in-camera or during post-processing.
Image Orientation: Image orientation refers to the rotation or alignment of an image, either in portrait (vertical) or landscape (horizontal) format. It affects the visual impact and composition of a photograph.
Image Bracketing: Image bracketing is a technique where multiple exposures of the same scene are captured at different settings, such as exposure, white balance, or focus. It is used to ensure a properly exposed and balanced image or for HDR processing.
Image Depth: Image depth refers to the perceived three-dimensional quality or sense of depth in a photograph. It is influenced by factors such as perspective, focal length, composition, and the arrangement of foreground, middle ground, and background elements.
In-camera Art Filters: In-camera art filters are creative modes or presets found in some cameras that apply various artistic effects or styles to images in real-time. They provide instant creative options without the need for post-processing.
Image Overlay Blend Modes: Image overlay blend modes are options available in image editing software that determine how two or more images are blended together. Examples include normal, multiply, screen, overlay, and more, each affecting the final result differently.
