Good Picture - 2004 Digital De-Mystified!
An RPS Symposium
Following the success of Good Picture 2003, the Imaging Science Group of the Royal Photographic Society is organising another in its series of tutorial seminars, open to all, on selected technical aspects of digital imaging. The aim of these lectures is to provide imaging practitioners, keen amateurs and students with insights into Digital Imaging and hopefully provide some tools and guidelines for assessing cameras and output.

Programme
Novartis/Daily Telegraph 2004 Visions of Science - Highlights
Prof. Ray Clark - RPS Past President
The Visions of Science competition produces superb attention-grabbing images that give new insight into the world of science and the workings of
nature. Winning images may show something never seen before, help explain a scientific phenomenon, illustrate scientific data or simply show the
beauty of science. This presentation will feature winning images from the 2004 competition.
From Shutter Click to Pixel - How Scene Colour Becomes Output Colour
Dr. Phil Green - London College of Communications
When a scene is photographed with a digital camera, the raw camera image undergoes initial processing within camera firmware or software to produce
an acceptable image on a colour display. Further transformations on the resulting data will be applied in order to render the image in print. Achieving a
good match between the appearance of the original scene and any resulting output involves the use of professional colour management tools, but also
requires some understanding of the transformations applied and the limitations of different media.
Digital Cameras - Image Quality Matters
Dr. Lionel Baker - Imaging Consultant
A sector star test chart and computer can be used to measure a parameter called the optimum print width. Camera controls can be selected and
different models compared using this metric. Practical procedures will be described for measuring this parameter as well as veiling glare and contrast
resolution. Results from different models will be presented and cameras may be tested on the day.
From Film to Foveon
Paul Reynolds - Sigma UK
Foveon is an American based company which in 2000 developed an innovative 3-layered image sensor for use in digital cameras. The sensor works in
a similar way to film in that each layer responds to a particular colour, red, green or blue. This talk looks briefly at the history of the Foveon company
and gives an insight into the technology of the 3-layered sensor.
Digital Cinema - Status and Image Quality Requirements for the Big Screen
Dr. David Monk - Texas Instruments
This talk will review the history and progress of digital and electronic cinema. It will discuss the key image quality requirements in relation to the Human
Visual System. As a keen film and digital photographer David will relate the new movie technology to the challenges facing digital photographers.
“DIY Photoshop 101”
Dr. Rob Jenkin - University of Cranfield
We all rely on the marvellous results produced by packages such as Adobe PhotoshopTM and Paintshop ProTM - but how many of us know what’s under
the bonnet? This talk lifts the lid on one of the core processes these packages use and encourages you to experiment by making your own. We'll
explore what actually happens when you sharpen, blur or find edges in an image. Strangely we'll find they are all the same flavour. Uprate your Metro
to a Ferrari by adding convolution to the tank!
JPEG and JPEG 2000
Elizabeth Allen - University of Westminster
This talk will introduce some of the concepts behind the lossy compression of photographic images, with reference to JPEG and JPEG 2000. The digital
image artefacts characteristic of each compression will be explained, and the trade-off between file size and image quality will be discussed.
The Truth is Out There!
Dr. Greg Duncan - Imaging Consultant
In many spheres of photography there are restrictions prohibiting manipulation which alters the truth of the statement of the image. This talk examines
the problems of defining what the truth is and determining an acceptable level of manipulation. It explores the range between obviously acceptable and
obviously unacceptable manipulations. In essence the talk shows that there is no discernible dividing line.
