Brightness, Contrast and Color


Guidelines

  • Brightness and contrast should be adjusted to present the subject and background accurately
  • Photos without proper contrast or color may obscure unique facial features
  • Color should reproduce natural skin tones
  • Fluorescent or other lighting with unbalanced color may cause unwanted color cast in the photo
  • Appropriate filters can eliminate improper color balance

Photo Examples

Photo Examples Banner
Brightness examples Very dark or very light apparel may cause certain auto-exposure systems to overcompensate, resulting in overly dark or light flesh tones. A neutral gray card may be used to set exposure at a consistent level before placing the subject in the scene.
spacer.gif
Contrast examples Contrast that is too high is usually due to the overall light and shade in the scene. Correct contrast can be achieved by directing diffused lighting onto the subject. Such lighting increases the local contrast while reducing the total contrast.
Color examples Picture is affected by the type of light used. Avoid mixing incandescent and fluorescent lighting. Corrective filters can improve the overall light that reaches the conventional film or digital camera sensor, and thus remove unnatural color effects. A neutral white card may be used to set the white balance level on some advanced digital cameras.

Head Position and Background


Guidelines

  • Head should be positioned directly facing the camera
  • Photo should capture from slightly above top of hair to middle of chest
  • Eyes should be open and looking at the camera
  • Eyeglasses should be worn if normally used by the subject
  • Glare on eyeglasses can usually be avoided with a slight upward or downward tilt of the head
  • Background should be plain white or off-white
  • Include headpieces if worn daily for religious purposes; they should not obscure or cast shadows on the eyes or any other part of the face

Photo Examples

Photo Examples Banner
Head position example To prevent geometric distortion and ensure an adequate depth of field, the camera should be placed at the subject’s eye level and approximately 4 ft (120 cm) from the subject.

By placing the subject on an adjustable height seat, the height of the camera tripod can be fixed.

A lens of about 105 mm focal length on a 35 mm film camera, or its equivalent on any other camera, should provide a sufficiently flat field-of-view.

The subject’s eyes should look directly at the camera and the subject may be either smiling or not, but unusual expressions and squinting should be avoided.

spacer.gif
Eyeglass glare example A slight downward tilt of the head will usually eliminate glare on eyeglasses.  If this does not reduce the glare, try tilting the head slightly upward or rotating the glasses slightly upward or downward.  The head should not be tilted by more than a few degrees to eliminate glare.

ȁC;Red EyeȁD; conditions should be avoided.  Red eye is caused by a direct reflection, through the pupil, from the retina of the eye when an on-camera flash is used, particularly for a subject who has adapted to a darkened environment.  Red eye can be reduced by using an off-camera flash or by brightening the ambient lighting.

Subject background example A distracting background should be avoided.  Use a plain wall or a photographer’s backdrop cloth as the background.  The background color may be white or off-white.

Ideally, the background will be out of focus so that minor markings or texture on the background are not apparent in the photo.

Exposure and Lighting


Guidelines

  • Over-exposure or under-exposure may render the photo unusable
  • Three-point balanced lighting is strongly recommended (see Figure 1)
  • Facial features should be clearly evident in the photo
  • Lighting should be adjusted to avoid shadows on the face or background
  • Diffuse sources of light , such as umbrella lights, are preferable to point sources

Photo Examples

Photo Examples Banner
Exposure example Over-exposure occurs when the image receives too much light; it results in a loss of resolution (very fine detail), more graininess and less detail in highlight areas. Under-exposure occurs when the image receives too little light; it results in loss of detail in the subject’s shaded areas, which can become dark and featureless.

Exposure problems can be avoided by conforming to the recommended lighting arrangement (Figure 1) and using diffuse light sources of moderate lamp intensity.

spacer.gif
Background shadows example Illuminating the background is best accomplished with a light source that spreads illumination evenly over a wide area.

Correct positioning of back-lighting, below the subject and radiating up, will reduce or remove shadows from the background without affecting the amount of light incident on the subject.

Facial shadows example To avoid shadows on the face, the amount of light striking a subject''s face from two sides, should be equal. In a balanced lighting arrangement, if one of the two light sources is of a lower intensity, move it closer to the subject to offset the difference in light intensity.

Overhead lighting can produce unwanted shadows on the face and should be avoided whether balanced lighting is used or not.

Resolution and Printing Quality


Guidelines

  • High- resolution photography and printing are strongly recommended
  • Both conventional and digital photography are acceptable, and conventional or digital printing methods may be used
  • Resulting print should exhibit a continuous-tone quality regardless of the print method used (dye sublimation, ink jet, laser, etc.)
  • Digitally printed photos should be produced without visible pixels or dot patterns
  • Fine facial features should be discernible
  • The entire face should be in focus

Photo Examples

Photo Examples Banner
Discernible pixels example Image quality and resolution are directly related: the higher the resolution, the better the image quality. For conventional photography, high resolution is inherently achieved through the use of 35 mm film stock. In digital photography, the size of the camera's digital sensor determines the degree of resolution that can be achieved.

Avoid using a low-resolution digital camera. After images are loaded into the camera's memory and displayed on a monitor, images are often smaller than expected or there are discernible pixels (image pixelation) when the images are enlarged on the monitor or output to a printer.

spacer.gif
Coarse dot pattern example Images that look fine on a computer screen may appear coarse or grainy when printed, even at the 2 inch x 2 inch dimension. This can be attributed to the differences in image resolution for the display monitor and the digital printer, with respect to the amount of image data available. Digital printers have variable resolution settings, and the proper setting needs to be selected to avoid having an image appear fuzzy or grainy. However, no printer resolution setting can adjust for too little data in the image caused by use of an inappropriate camera lens or low-resolution digital camera.
Focusing example The subject’s face should be the central or principal point of focus. It may be necessary to adjust the distance setting on the camera’s lens once the subject is framed in the scene. If excessive adjustments are needed to focus properly, the lens being used may not have a suitable focal length (approximately 105 mm) and may cause unwanted distortions in the image.

Setup and Production Guidelines


Successful U.S. passport and visa photography begins with careful setup and appropriate production methods.

Proper Lighting Arrangement

Figure 1. Camera & Lighting Setup

Figure 1. Camera & Lighting Setup

Camera/ Subject Position

  • Place camera approximately 4 ft (120 cm) from the subject.
  • Have camera at subject's eye level.
  • Position subject facing the camera.

Photograph Print Properties

  • Produce 2 inch x 2 inch (51 mm x 51 mm) color photo.
  • Print photo on thin photo paper or stock.
  • Ensure the print is clear and has a continuous-tone quality.
  • Do not retouch or otherwise enhance or soften photo.

    Digital Photography and Printing


    Using digital photography to produce passport and visa photos involves more than just photographing subjects with a digital camera. That is just the first step, the image capture step, of a multi-step process that also includes image display and image printing using computer and printer equipment. Each of these components — can influence either positively or negatively — the final printed photo that will be submitted for the passport or visa. The following recommendations for each of these digital components will ensure high-quality photos.

    Digital Camera

    Digital cameras are principally characterized by their image resolution or mega-pixel capacities; from low-resolution (less than 1 mega-pixel) to high-resolution (greater than 1 mega-pixel) to advanced high-resolution (4 mega-pixels or more). The camera''s resolution is the most critical feature in producing high-quality photographs. For U.S. passport and visa photographs, a digital camera with a resolution of 1 mega-pixel will be more than adequate for capturing the image and producing the final photo that conforms to the dimensions specified on this web site.

    These cameras generally have automatic features for controlling many of the photographic qualities emphasized on the preceding web pages. Care should be taken not to rely totally on these controls since each subject — facial characteristics, clothing, facial movement, etc. — can vary and may not be accommodated for by the automatic settings.

    Cameras with a direct electronic camera-to-computer interface are preferable to those requiring the use of an external memory card. Data transfers will occur much faster and allow for verification of a good image being stored in the computer. If a retake is required because the subject blinked or moved, it would be more convenient than taking several shots to be sure of a good one and then downloading them via the memory card.

    Computer

    The computer is the central component in digital photography. It stores and displays the digital images from the digital camera and enables those images to be printed on a variety of digital printers. Because of the huge amount of data contained in high-resolution digital images, the computer should have adequate memory and storage capacities. In addition to these two key elements, the computer should have high-speed interfaces to the camera and printer, as well as a fast CPU to control the image processing functions. The recommended computer configuration for processing digital images is provided below:

  • CPU Speed: 1.4 GHz
  • Main Memory: 128 MB RAM
  • Hard Drive Storage: 20 GB
  • Interfaces: High-speed interfaces to match your camera and printer, such as Firewire or USB 2.0

Display Monitor

Most display monitors today are capable of displaying images in various screen resolutions, all of which are suitable for viewing passport and visa images. These monitors also display images in a wide variety of colors. However, an image can look quite different when viewed on various display monitors, in terms of both screen resolution and image quality. For this reason, it is important to set the monitor''s settings to the manufacturer''s default values to view the image in the most appropriate manner. For more accurate color-matching, check that the calibration of your monitor is correct. If necessary, use the monitor''s control panel to fine-tune its color adjustments; for instance, to set the monitor''s color temperature to 6500 ºK to approximate daylight. For even greater color accuracy, the stored image can be converted to and displayed in a device-independent color space by using standard image display software. This removes the color bias of the specific display monitor and will more accurately represent the way the image should actually appear.

Printer

If digital printers are used to produce passport and visa photographs in lieu of conventional photographic processes, the photographs produced must be high quality and photo-like in appearance. Certain types of digital printers such as — inkjet and dye sublimation — can be used to produce high-quality passport and visa photos. Inkjet printers deposit multi-colored ink onto photographic print paper. Dye sublimation printers use heat, applied to a multi-colored ribbon or film, to release a dye that is transferred onto photographic print paper. These two types of printers, when used with compatible print paper that produces high resolution, photo-like images, are suitable for printing passport and visa photos. They have multiple printer settings to control the format, print resolution, and print quality of the printed photo. In addition, they come with printer-specific device driver software that converts the stored image pixel data in the computer into the actual printer output to be printed onto the photographic paper. Just as with display monitors, printers have their own unique color profile that should be taken into account before the image is printed. The combination of proper printer settings and photo-quality paper determines whether high-quality photos can be obtained.

Avoiding Photo Printing Problems

Using digital photography to produce high-quality passport and visa photos is dependent on the condition and proper use of the digital camera, computer, display monitor, and digital printer. Maintaining the digital printer in good working order however, can be the single most important aspect of producing quality photos. Regardless of how much attention is paid to capturing, storing, and displaying an image, image quality will be poor if printers — including inks and ribbons — are not properly maintained. To ensure that a quality print is obtained, the image can be transferred to disk and taken to a photo lab to be printed. The equipment found in a photo lab will normally be capable of producing higher-quality photos and undergoes the frequent calibration and maintenance necessary for consistent results.

Glossary of Terms


Ambient Light - the available light completely surrounding a subject that is not introduced artificially.

Aperture - the opening in a camera lens through which light passes; measured in f-stops.

Background - the area behind the subject; it should be smooth, flat, and non-patterned to minimize unwanted reflectance; the background should be plain white or off-white.

Background Illumination - light that illuminates the background. The background should be uniformly illuminated to remove any shadows or other lighting effects that would otherwise interfere with clearly discerning the facial outline on the background.

Bit - short for binary digit, which in a computer is the smallest unit of storage.

Brightness - the amount of light and dark areas in an image.

Byte - short for binary term; a collection of computer bits; on many modern computers, a byte is equal to eight bits.

Cast - See Color Balance, Color Cast & Color Correction

Centering - the orientation of the facial region within the frame; head should be positioned such that the approximate horizontal mid-points of the mouth and bridge of nose lie on a vertical line at the horizontal center of the photo width; and a horizontal line through the center of the subject's eyes can be located approximately 55% from the vertical bottom of the photo; and the width of the subject's head is approximately 50% of the width of the photo.

Color Balance - how a color film reproduces the colors of a scene; using the wrong lighting can cause the colors to appear washed out or unnatural.

Color Cast - the overall bias towards one color in a color image.

Color Correction - applying filters which help balance the color rendition of a scene to match the color response of the eye

Composition - the content and organization of the image that is being captured for the photograph. In this context, the composition of the photograph must show a clear, front view and full face of the subject against a plain and neutral light color background.

Continuous-Tone - refers to an image where like colors in the subject and scene do not change abruptly; the opposite of posterization.

Contrast - the range of difference in the light to dark areas of an image.

Diffuse Lighting - lighting that is low or moderate in contrast, such as on an overcast day.

Dot - the smallest element that can be printed by a digital printer.

Exposure - in photographic terms is the product of the intensity of light and the time the light is allowed to act on the film, or digital camera sensor. In practical terms, the aperture controls intensity or amount of light and shutter speed controls the time.

Eye Height - the distance from the bottom of a passport or visa photo to a horizontal line going through both eyes and which should measure between 1 inch (25 mm) and 1 3/8 inches (35 mm).

Facial Features - the makeup or appearance of a subject's face or its parts, including scars, tattoos, etc.

Facial Region Illumination - the light that is incident on the subject's face. The face should be clearly illuminated with all physical features shown and no shadows that would otherwise obscure the facial image.

Facial Region Size - the facial region as measured from the bottom of the chin to the top of the head (including hair) and should be between 1 inch (25 mm) and 1 3/8 inches (35 mm).

File Size - the size of an image in digital photography, measured in kilobytes (KB), megabytes (MB), or gigabytes (GB). File size is proportional to its pixel dimensions; images with more pixels may produce more detail at a given printed size, but they require more disk space to store and are slower to print.

Film - photographic emulsion coated on a flexible, transparent base that records images or scenes.

Film Speed - the sensitivity of a film to light, indicated by a number such as ISO 100. The higher the number, the more sensitive or faster the film. (ISO stands for International Organization for Standardization)

Filter - colored piece of glass or other transparent material used over the lens to emphasize, eliminate, or change the color of the entire scene or certain areas within a scene.

Focal Length - the distance between the film and the optical center of the lens when the lens is focused on infinity. The focal length of the lens on most adjustable cameras is marked in millimeters on the lens mount.

Focus - the adjustment of the distance setting on a lens to define the subject sharply.

Focus Range - the range within which a camera is able to focus on the selected subject; i.e., from 4 feet to infinity.

Foreground - the area between the camera and the principal subject.

Graininess - the sand-like or granular appearance of an image. Graininess becomes more pronounced with faster film and the degree of enlargement. In digital imaging, graininess may occur as a result of printing an image, the pixel resolution of which is too coarse, or as a result of using a printer with poor dot resolution.

Grayscale - term used to describe an image that only contains shades of gray

Head Orientation - the positioning of the subject's head, specifically positioning the face to the full frontal position, eyes level and open. For those individuals that wear glasses, proper head orientation is crucial in avoiding unwanted glare from glasses. Even so, care should be taken to meet the required facial area and face centering guidelines outlined in this brochure when positioning the subject's head to remove the potential glare.

Hue - the attribute of colors that allows them to be designated as red, green, blue, or any intermediate combination of these colors.

Lens - one or more pieces of optical glass or similar material designed to collect and focus rays of light to form a sharp image on the film or digital camera sensor.

Lighting Arrangement - the lighting arrangement for subject illumination which should consist of a minimum of 3 point balanced illumination; two (2) points of illumination should be placed at approximately 45 degrees on either side of the subject's face, the third point should be placed so as to illuminate the background uniformly.

Natural Expression - The subject's expression should be natural, with both eyes open. Please refer to the photographs found on this website for acceptable facial expressions.

Negative - the developed film that contains a reversed tone image of the original scene.

Neutral Gray Card - a gray test card without any hue, typically of 18% reflectance.

Neutral White Card - a white test card without any hue, typically of 90% reflectance.

Over-exposure - refers to a condition where too much light reaches the film or digital camera sensor, either because it is too bright or has been applied too long, resulting in a very light photograph.

PPI - short for pixels per inch; the measurement of resolution for displaying or printing digital images.

Pixel - short for picture element; a single picture element of a digital photo or displayed image. Taken together, all of the millions of pixels form a grid that represents the content of the image.

Pixelization - the graininess in an image that results when the pixels are too big, relative to the size of the image.

Positive - the opposite of a negative, an image with the same tonal relationships as those in the original scenes, for example, a finished print.

Posterization - the effect produced when a photographic image is displayed or printed with too few colors or shades of gray; the opposite of continuous-tone.

Print - refers to an exposed film picture that is printed on photographic paper, in color or black and white. In digital imaging, a print is the result of printing the digital image on photographic-quality paper stock using a digital printer. For passport/visa photographs, the resulting print should measure 2 inches x 2 inches (51 mm x 51 mm).

Printing - producing the final photo of the captured image which should enable fine facial features to be discernable, whether the print results from conventional photographic processes or digital printout. The resulting print should exhibit a continuous-tone quality regardless of the print method used.

Proper Lighting - the type and position of lighting for both the subject and background so that the subject is clearly illuminated with no shadows on the face or the background.

RGB - the way that the colors are recorded in digital imaging. A large percentage of the visible spectrum can be represented by mixing red, green and blue (RGB) colored light in various proportions and intensities.

Reflectance - the light intensity emitted from a surface in a given direction.

Resolution - refers to a measure of the detail that can be seen in an image; the higher the resolution, the finer the detail that can be seen.

sRGB - refers to a standard default RGB color space. This is a device-independent color space designed to remove any color-bias from the representation of an image on the specified device.

Sharpness - refers to whether an image appears to be in focus.

Subject Pose - the subject's head, face and shoulders which should be oriented so that the full face frontal view varies no more than ±5 degrees from frontal in every direction.

Subject Positioning - the position of the subject with respect to the camera; the subject should be placed in front of the background such that the focal distance from the camera's lens to the subject's face should be no closer than 120 cm.

Tone - refers to the degree of lightness or darkness in any given area of a photo.

Under-exposure - refers to a condition where too little light reaches the film or digital camera sensor, either because the light is not sufficient or it hasn't been applied long enough; it results in a very dark photograph.
