Using Photoshop’s Camera Raw plug-in
Posted by ivanckw at June 18th, 2007
Back in the days of film-based photography, it was common practice to either get your local photo developer to process your film or to hop off to your darkroom and do it yourself.
Although the latter clearly gave greater control over the end result, both had the distinct advantage of preserving a negative with the raw image data captured from the camera. One big advantage of digital photography is that time-consuming processes like these are eliminated. Unfortunately, digital photography also takes away much of the control over the way our images are processed – the CCD inside your digicam automatically does all the processing for you and, worse still, actually throws image information away when you shoot in JPEG mode. Serious photographers can wrestle the initiative back from their overzealous CCDs by shooting in Raw format.
Not all digicams offer this option, but many prosumer and virtually all professional models do. Unlike JPEG, which is a lossy format, Raw files include the exact, unprocessed data captured by your digicam’s CCD. Shooting in Raw format gives you greater control over the way your images turn out; the downside is that you have to do all the processing, including setting the exposure, white balance and colour balance yourself.
All digital cameras have their own proprietary Raw modes and most that support Raw mode come with their own software for processing the Raw files. For the purpose of this tutorial, however, we’ll be using Adobe’s excellent Camera Raw plug-in. To give you an idea of the quality of this software it was developed by Thomas Knoll, the founding father of Photoshop himself. If you’ve got Photoshop CS, Camera Raw is included for free. Not all digicams are supported by this plug-in, however – for the record we’re using a Canon PowerShot G5 here – so to check if your model is compatible, pay a visit to www.adobe.com/products/photoshop/cameraraw.html.
