"Digital photography uses cameras containing arrays of electronic photodetectors interfaced to an analog-to-digital converter (ADC) to produce images focused by a lens, as opposed to an exposure on photographic film."
The practice of taking and editing photos using digital tools.
Camera basics: Understanding your camera’s settings and controls, including ISO, shutter speed, aperture, and focal length.
Composition: The art of arranging visual elements in a photograph to create a pleasing image.
Lighting: Knowing how to work with natural and artificial light to create the desired effect in your photos.
Exposure: Understanding the relationship between shutter speed, aperture, and ISO to achieve the correct exposure.
Color theory: Understanding color combinations and how they contribute to the mood and impact of a photograph.
Editing software: Learning to use popular editing programs such as Photoshop or Lightroom to enhance and manipulate images.
Image resolution: Understanding the concept of resolution and how it affects the quality of your images.
File formats: Knowing the differences between file formats such as JPEG, TIFF, and RAW and which ones to use in different situations.
Depth of field: Understanding how the depth of field affects how much of a photo is in focus.
Digital image processing: Learning the basics of digital image processing including masking, selection, and retouching.
White balance: Understanding how to correctly set the white balance of your camera to achieve natural-looking colors.
Lens choice: Understanding how different lenses affect the look and feel of an image.
Megapixels: Understanding how megapixels relate to image resolution and image quality.
Histogram: Knowing how to read and use the histogram to adjust your camera settings and achieve the desired exposure.
Camera sensors: Understanding the differences between camera sensors, including full-frame and APS-C, and how it affects the final image.
Aperture priority mode: Understanding how to use aperture priority mode to control depth of field.
Shutter priority mode: Understanding how to use shutter priority mode to control motion blur.
Manual mode: Understanding how to use manual mode to have full control over your camera settings.
RAW format: Understanding the advantages and disadvantages of shooting in RAW format.
Photography styles: Understanding different photography styles, including portrait, landscape, and street photography, and how to capture them.
Fine art photography: This is photography intended to be enjoyed for its aesthetic value. Fine art photography typically encompasses a range of subjects, including landscapes, still life, and portraits.
Portrait photography: This is the practice of taking photographs of people, either individually or in groups. Portrait photography focuses on capturing the personality and essence of the subject.
Fashion photography: This is a subset of portrait photography, but with a focus on clothing and accessories. Fashion photography is often used in magazines and advertisements to promote clothing lines.
Landscape photography: This is the practice of taking photographs of natural scenery, such as mountains, lakes, and forests. Landscape photography often aims to capture the beauty and grandeur of nature.
Wildlife photography: This is the practice of taking photographs of animals in their natural habitat. Wildlife photography often requires patience and skill, as the photographer must wait for the right moment to capture the perfect shot.
Street photography: This is the practice of taking candid photographs of people in public spaces, often in urban environments. Street photography aims to capture the essence of everyday life.
Sports photography: This is the practice of taking photographs of athletes and sporting events. Sports photography requires skill and experience, as the photographer must be able to anticipate and capture fast-paced action.
Documentary photography: This is photography intended to document a particular subject or issue. Documentary photography often focuses on social or political issues, but can also encompass a range of other subjects.
Food photography: This is the practice of taking photographs of food, often used in cookbooks, magazines, and advertisements. Food photography often requires careful attention to lighting and composition.
Abstract photography: This is photography that does not have a clear subject, but instead focuses on color, shape, and texture. Abstract photography often creates beautiful and intriguing images that challenge the viewer's perspective.
"The digitized image is stored as a computer file ready for further digital processing, viewing, electronic publishing, or digital printing."
"Until the advent of such technology, photographs were made by exposing light-sensitive photographic film and paper, which was processed in liquid chemical solutions to develop and stabilize the image."
"In consumer markets, apart from enthusiast digital single-lens reflex cameras (DSLR), most digital cameras now come with an electronic viewfinder, which approximates the final photograph in real-time. This enables the user to review, adjust, or delete a captured photograph within seconds, making this a form of instant photography, in contrast to most photochemical cameras."
"Moreover, the onboard computational resources can usually perform aperture adjustment and focus adjustment (via inbuilt servomotors) as well as set the exposure level automatically, so these technical burdens are removed from the photographer unless the photographer feels competent to intercede."
"Digital cameras may choose to emulate traditional manual controls (rings, dials, sprung levers, and buttons) or it may instead provide a touchscreen interface for all functions; most camera phones fall into the latter category."
"Much of the technology originated in the space industry, where it pertains to highly customized, embedded systems combined with sophisticated remote telemetry."
"Any electronic image sensor can be digitized; this was achieved in 1951."
"An early semiconductor milestone was the advent of the charge-coupled device (CCD) image sensor, first demonstrated in April 1970."
"The first consumer digital cameras were marketed in the late 1990s."
"Professionals gravitated to digital slowly, converting as their professional work required using digital files to fulfill demands for faster turnaround than conventional methods could allow."
"Starting around 2000, digital cameras were incorporated into cell phones; in the following years, cell phone cameras became widespread, particularly due to their connectivity to social media and email."
"Since 2010, the digital point-and-shoot and DSLR cameras have also seen competition from the mirrorless digital cameras, which typically provide better image quality than point-and-shoot or cell phone cameras but are smaller in size and shape than typical DSLRs."
"Many mirrorless cameras accept interchangeable lenses and have advanced features through an electronic viewfinder, which replaces the through-the-lens viewfinder of single-lens reflex cameras."
