ADRIAN HENDROFF / Dingle
Peninsula, southwest Ireland
The fi ne, sandy beach at Brandon
Bay stretches for around 7½ miles
in an elegant arc from Fahamore to
Ceann Duimhche. The water’s edge
is elemental, constantly changing
depending on the weather and the
light. Its exposure to the Atlantic
means it often receives long rolling
swells, which adds to the drama. I
was lucky to have my camera with
me during an evening’s stroll when a
passing Atlantic cold front fi lled the
sky with dramatic rolling, swirling
clouds with sunbeams bursting
through. For a fl eeting moment, the
low cloud peeled off the summit of
Masatiompan to reveal its northeast
spur dropping steeply down to
Brandon Point.

From JPEG to PPI
Perplexed by jargon when supplying
photos to a publisher or to an image
library? Here’s a short cut-out-
and-keep guide to some of the more
common terms you may encounter...
Aspect Ratio
A numerical description of the
ratio of the width of an digital
image or screen compared to its
height. The aspect ratio of DSLRs
and compact system cameras
(CSCs) is 3:2, HD video is 16:9.
Bleed area
A 3-5mm area outside the
boundaries of a page design.
Images that stretch to the edge of a
page need to extend into the bleed
area to allow for slight variation in
trimming when the page is cut to
size after printing.
Short for Digital Assest
Management, the act of importing,
storing and cataloguing digital
fi les for easy retrieval. Assets can
be managed manually but it’s
far easier to use dedicated DAM
software to keep track of fi les.
Metadata
IPTC PPI
Metadata that contains
information about how a digital
fi le was created. Cameras add
shooting information, such as
exposure settings, in the EXIF
metadata of digital photos.
A metadata standard adopted and
supported by software developers
such as Adobe. IPTC metadata
is added to digital photos after
shooting, and can include details
such as a short description of the
photo, relevant keywords, as well
as relevant copyright details.
JPEG
Digital image fi le commonly
created by digital cameras. The
advantage of JPEG is that it can
be used directly from a camera
in a wide variety of ways, such as
uploading for display on the web.
However, JPEG is a compressed
fi le, with the compression
removing fi ne detail. JPEG can
be used in print, but ideally
compression should be kept to a
minimum, with the image saved at
the highest quality setting.
Information embedded in a digital
image or sound fi le. Metadata
usually describes aspects of the
fi le, either added automatically
when the fi le was created or
entered manually in post-
production. See EXIF and IPTC.
Pixels Per Inch (or PPCM/Pixels
per Centimetre, if you’re feeling
metric). The number of pixels
required to produce one inch
across a print. The standard for
repro is 300ppi. A photo 3000
pixels across could therefore be 10
inches across on the page (though
you’d need to allow for loss of part
of the photo due to the bleed area
if it’s used edge-to-edge). PPI is
often - incorrectly! - referred to as
DPI, or Dots Per Inch.
RAW
A digital photo format created by
DSLRs and CSCs, that retains all
of the image data captured at the
time of exposure. This lets you
post-process your photos to suit.
The downside is that Raw fi les
need to be post-processed and
can’t be used immediately.
