Stock photography: what you need to know

• A. Custom photography created for a single client's exclusive project
• B. Pre-existing photographs licensed for use by multiple buyers ✓
• C. Photos taken by news agencies to document current events
• D. Images created exclusively for museum and gallery displays

Why: Stock photography refers to existing images that photographers make available for license, allowing many buyers to use them for different purposes.

• A. Illustrating websites, blogs, and marketing materials ✓
• B. Serving as legal evidence in court cases
• C. Replacing official government identification photos
• D. Recording private family events exclusively

Why: Stock photos are widely used to illustrate websites, blog posts, advertisements, presentations, and other marketing materials cost-effectively.

• A. Free use of the image forever with no restrictions at all
• B. A one-time payment that permits repeated use without paying additional fees per use ✓
• C. Use only by the original photographer and no one else
• D. Permission to resell the photo as an unaltered stock image

Why: Royalty-free licensing typically involves a single upfront payment that allows repeated use without owing ongoing royalties, though specific terms and restrictions still apply.

• A. A contract signed by a photographer giving up copyright ownership
• B. A document where a recognizable person permits commercial use of their likeness ✓
• C. A certificate confirming a camera's professional calibration
• D. A payment receipt issued by a stock agency to the buyer

Why: A model release is a signed agreement from an identifiable person allowing their image to be used commercially, which is often required for stock photos featuring people.

• A. It determines the camera settings needed for the shot
• B. It helps buyers find images through search, increasing the chance of sales ✓
• C. It legally protects the photo from being copied online
• D. It removes the need for a model release

Why: Accurate and relevant keywords help search engines within stock libraries surface an image to potential buyers, directly affecting its visibility and sales.

• A. Buyers rarely search for photos in a particular subject area
• B. A focused portfolio helps buyers recognize your style and makes it easier to build a consistent body of work
• C. Agencies only accept photographers who specialize in one category
• D. Niche photos always sell for higher prices than general photos

• A. Abstract fine-art images of smoke and fog
• B. Business and workplace scenes showing diverse teams collaborating
• C. Extreme close-ups of a single antique coin
• D. Long-exposure night shots of empty city streets

• A. Assuming that any subject you find interesting will sell
• B. Searching stock agency websites to see how many similar images already exist and what keywords are popular
• C. Waiting until a client requests the image
• D. Only shooting subjects that are trending on social media that day

• A. To increase the file size of each photo
• B. To prove the photographer owns the camera equipment
• C. So that recognizable people or private property can be licensed for commercial use without legal issues
• D. Because releases are required to upload photos in black and white

• A. Hands typing on a laptop with a coffee cup nearby
• B. Regional wildlife found only in a remote national park
• C. Local street food prepared by vendors in a specific neighborhood
• D. Hand-lettered signage in a small town's historic district

• A. Shutter speed
• B. Aperture ✓
• C. ISO
• D. White balance

Why: Aperture is the adjustable opening in the lens diaphragm. A wider aperture (smaller f-number) lets in more light, while a narrower one lets in less and also increases depth of field.

• A. It makes the sensor less sensitive to light, producing darker images
• B. It makes the sensor more sensitive to light, allowing brighter images in low light but adding more digital noise ✓
• C. It slows down the shutter speed automatically
• D. It changes the color temperature of the image

Why: ISO measures the sensor's sensitivity to light. Raising it brightens images in dim conditions, but it also amplifies noise, which reduces image quality.

• A. JPEG at the lowest possible quality to save space
• B. A screenshot saved as PNG
• C. High-quality JPEG or TIFF at the camera's maximum resolution ✓
• D. GIF with a limited color palette

Why: Stock agencies require high-resolution, sharp, uncompressed or minimally compressed files. High-quality JPEG or TIFF at full resolution meets these standards, while low-quality or limited-color formats do not.

• A. To increase the depth of field
• B. To reduce motion blur caused by camera shake or moving subjects ✓
• C. To increase ISO sensitivity
• D. To balance the white balance

Why: A fast shutter speed freezes movement and reduces blur from hand shake. A common rule of thumb is that handheld shutter speed should be at least 1 divided by your focal length (in mm) to avoid camera shake.

• A. Stock buyers only accept black-and-white images
• B. Blurry or soft images are often rejected by reviewers and are less useful to buyers who need clear, professional visuals ✓
• C. Sharp images always have lower file sizes
• D. Focus only affects video, not still photos

Why: Stock reviewers reject images that are soft or out of focus, and buyers need crisp images that work at many sizes. Sharp focus on the main subject is a basic technical requirement for acceptance.

• A. Symmetry
• B. Rule of thirds ✓
• C. Leading lines
• D. Negative space

Why: The rule of thirds divides the frame into a 3x3 grid. Placing key subjects at the intersections or along the lines creates a balanced, engaging image that buyers find easier to crop and use.

• A. It creates harsh, dramatic shadows
• B. It produces even tones with gentle transitions, flattering subjects and suiting a wide range of uses ✓
• C. It always makes colors more saturated
• D. It eliminates the need for a camera

Why: Soft light, such as from an overcast sky or a diffuser, minimizes harsh shadows and gives clean, versatile images that work well across many commercial applications.

• A. Adding objects that were not in the original scene
• B. Adjusting exposure, contrast, and white balance for accuracy and clarity ✓
• C. Removing people to change the story without disclosure
• D. Heavily altering skin texture to look unnatural

Why: Standard corrections to exposure, contrast, and white balance are expected. Adding or misrepresenting content violates most agency guidelines and can mislead buyers.

• A. It makes files smaller
• B. It gives room for adding text, headlines, or logos in the design ✓
• C. It is required for all releases
• D. It replaces the need for good focus

Why: Negative space is empty area in the frame. Designers use it for copy and branding, so images with clean open areas are more commercially useful.

• A. Using a tripod
• B. Shooting at a consistent white balance
• C. Cluttered backgrounds that distract from the main subject ✓
• D. Shooting in natural light

Why: Busy or cluttered backgrounds compete with the subject and make images harder to use. Clean, simple backgrounds keep attention on the focal point and suit more projects.

• A. To prove the photographer owns the camera equipment used
• B. To grant permission for the image to be used commercially and identify the person's consent to appear in the photo ✓
• C. To certify the photo has been professionally edited
• D. To guarantee the model will be paid royalties for every download

Why: A model release is a signed document in which the person photographed grants permission for their likeness to be used, and it is typically required for commercial stock images that show identifiable people.

• A. A landscape photo of a mountain with no buildings visible
• B. A close-up of a flower in a public park
• C. A photo of a privately owned house, building, or interior space that is recognizable ✓
• D. An abstract image of colored light patterns

Why: Property releases are needed when identifiable private property, such as a recognizable house, building, or interior, appears in an image, because the owner's rights could be implicated in commercial use.

• A. Because releases increase the file size of the image
• B. Because without consent the person could challenge commercial use of their likeness, creating legal risk for buyers and the agency ✓
• C. Because stock agencies only accept photos taken in studios
• D. Because model releases are required to adjust the image's color balance

Why: Using someone's likeness commercially without consent can lead to right-of-publicity or privacy claims, so agencies require releases to protect buyers and themselves from legal exposure.

• A. A release is only needed if the model is a professional actor
• B. A release signed once covers all photos from the shoot indefinitely in every country
• C. A release should be signed by the model, ideally before or at the shoot, and kept on file with the photographer ✓
• D. A release is only necessary for editorial images, not commercial ones

Why: Releases should be signed by the model (or a parent/guardian for minors), ideally before shooting, and retained by the photographer as proof of permission, since agencies may request them.

• A. No release is ever needed for people in public places
• B. A signed model release should be obtained if the person is identifiable and the image will be used commercially ✓
• C. Only a property release is needed since the street is public
• D. The photographer can simply blur the face to avoid needing any paperwork

Why: Being in a public place does not remove privacy and publicity rights for identifiable individuals in commercial use, so a model release is the safe practice; blurring may not always suffice for identifiability.

• A. To change the image's resolution for printing
• B. To help buyers find the image through search results ✓
• C. To compress the file size for faster uploads
• D. To add a watermark that protects the image from copying

Why: Keywords are descriptive terms attached to an image so that buyers searching a stock site can discover it. Good keywording directly affects how often an image appears in search results and gets licensed.

• A. Using as many keywords as possible, including unrelated terms to attract more views
• B. Repeating the same keyword several times to strengthen its ranking
• C. Using relevant, specific keywords that accurately describe the image's content ✓
• D. Using only single-word keywords that are as broad as possible

Why: Stock sites penalize irrelevant or spammy keywords and may reject or remove images that are misleadingly tagged. Accurate, relevant keywords that describe subject, setting, mood, and concept perform best with buyers and in search algorithms.

• A. A private note visible only to the photographer
• B. A short descriptive sentence summarizing the image for buyers ✓
• C. The camera model and lens used to capture the shot
• D. The legal license type selected for the image

Why: The title is a concise, descriptive sentence shown to buyers in search results and on the image page. It should clearly describe the main subject and context without keyword stuffing.

• A. Brand names make the image file size larger
• B. Trademarks can cause legal issues and may lead to the image being restricted to editorial use only ✓
• C. Search engines will block images with brand names from appearing
• D. Brand names reduce the image's resolution during upload

Why: Using trademarked names or logos in commercial stock imagery without a property release can create legal risk for buyers. Such images may be rejected or limited to editorial use, so keywords should avoid implying brand endorsement.

• A. Alphabetically, so buyers can scan them easily
• B. Shortest to longest, to match typical search lengths
• C. Most important and most relevant terms first, since buyers and systems weigh early keywords more heavily ✓
• D. Random order, since the platform reorders them automatically

Why: Many stock platforms give more weight to the first keywords listed, so leading with the most relevant and important terms helps the image surface for key searches.

• A. That every person is wearing brand-name clothing
• B. That you have a signed model release from each identifiable person
• C. That the people are smiling in every shot
• D. That the photo has been edited with heavy filters

Why: Agencies require model releases for identifiable people so that images can be licensed commercially. Without a signed release, the image may be rejected or restricted to editorial use only.

• A. A landscape with no buildings or structures
• B. A close-up of a flower in a public park
• C. A private home or identifiable building photographed without the owner's permission ✓
• D. A sunset over the open ocean

Why: Identifiable private property, such as a house or interior, requires a property release from the owner to be used commercially. Public scenes and natural landscapes generally do not.

• A. The image can be used in advertisements and product packaging
• B. The image can be used only for newsworthy, educational, or informational purposes, not for commercial promotion
• C. The image has been professionally retouched by the agency
• D. The image is exclusive and cannot be sold elsewhere

Why: Editorial licenses cover news, education, and commentary. Because the image lacks the releases needed for commercial use, it cannot be used to promote products or services.

• A. A very low resolution to reduce file size
• B. A high resolution with sufficient pixel dimensions and sharp focus ✓
• C. A format that only opens in one specific software program
• D. A watermark placed across the center of the image

Why: Buyers need high-quality files for print and digital use, so agencies typically require high resolution, sharp focus, and clean exposure. Watermarks and very low resolution would make images unsellable.

• A. They receive a one-time flat fee for uploading each image
• B. They earn royalties each time a buyer licenses one of their images ✓
• C. They are paid only when their images appear on the agency's homepage
• D. They pay the agency a monthly fee to have their photos displayed

Why: Contributors typically earn a royalty percentage from each license sold, so income grows as images are downloaded over time. Most agencies do not charge contributors to upload.
