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. www.adrianhendroff .com Next issue’s theme: Rock around the clock 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. spring 2018 | Outdoor focus 13 DAM EXIF
