Image Requirements – Technical Specifications
Acquisition
The image file may be produced by acquiring an image with a digital
camera or by digitizing a paper photograph with a scanner.
Dimensions
Image pixel dimensions must be in a square aspect ratio (meaning the
height must be equal to the width). Minimum acceptable dimensions
are 600 pixels (width) × 600 pixels (height). Maximum acceptable
dimensions are 1200 pixels (width) × 1200 pixels (height).
Color
Must be in color (24 bits per pixel ) in sRGB color space (common
output of most digital cameras).
File Format
Must be in the Joint Photographic Experts Group (JPEG) file
interchange format (JFIF).
File
Size Must be less than or equal to 240 kilobytes.
Compression
The image may need to be compressed in order for it to be under the
maximum file size. The compression ratio used should be less than or
equal to 20:1.
Additional requirements if scanning:
Print Size
If scanning the image from a paper photograph, the size of the paper
photograph should be at least 2 inches × 2 inches (51 mm × 51 mm)
square.
Resolution
Printed photographs should be scanned at a sampling frequency of at
least 300 pixels per inch.
Image Requirements – Composition
Content
• The image must contain the full face, neck, and
shoulders of the applicant in frontal view with a neutral,
non-smiling expression and with eyes open and
unobstructed and directed at the camera.
• All facial features must be visible and unobstructed.
• No extraneous objects, additional people, parts of the
body below the applicant´s shoulders, or other artifacts.
• The image must be from a recent (within 6 months)
photo of the applicant.
Head Size
• The head height or facial region size (measured from the
top of the head, including the hair, to the bottom of the
chin) must be between 50% and 69% of the image’s total
height.
• The eye height (measured from the bottom of the image
to the level of the eyes) should be between 56% and 69%
of the image´s height.
Head Orientation
• Subject must directly face the camera.
• Head must not be tilted up, down, to the side, or toward
the shoulders.
• Head must be centered within frame.
Background
• Subject must be surrounded by a plain, light-colored
background with no distracting shadows on the subject
or background.
Focus
• The entire face must be in focus and not overlysharpened.
Brightness/ Contrast
• Brightness and contrast should represent subject
accurately.
Color
• Image must be in color (24 bits per pixel).
• Black and white photos are not acceptable.
• Color should reproduce natural skin tones.
• Color must be continuous tone – no posterization.
Exposure/ Lighting
• Photo may not be over- or under-exposed.
• Avoid shadows on face or background.
Resolution • Fine facial features should be discernible.
• No discernible pixels/pixelization, graininess, or dot
patterns.
Compression
• Image must not be overly compressed (the compression
ratio used should be less than or equal to 20:1).
Alteration • Digital enhancement or other alterations or retouching
are not permitted.
• When resizing, the aspect ratio of the image must be
preserved (no image stretching is allowed).
Eyeglasses • Eyeglasses are acceptable in photo only if the lenses are
not tinted and there is no glare, shadows, or rims/frames
obscuring the eyes. Glare on eyeglasses can usually by
avoided by a slight upward or downward tilt of the head.
• Dark glasses or nonpreion glasses with tinted
lenses are not acceptable unless you need them for
medical reasons.
Decorative Items
