An RPS Symposium
Following the success of the previous six Good Picture Symposia, the Imaging Science Group of the Royal Photographic Society held another in its series of tutorial seminars (on 12 December 2009) on selected technical aspects of Digital Imaging. The aim of these lectures and discussions is to provide imaging practitioners, keen amateurs and students with insights into Digital Imaging and provide some tools and guidelines for assessing cameras and output.
Some of the papers presented may be downloaded (see links below) by kind permission of the authors, as and when the files become available to us.
Programme
Dr. Sophie Triantaphillidou ASIS FRPS - Visual Perception and Manipulation
University of Westminster
This talk is concerned with the way visual information is processed by the eye and
the brain to allow us making sense of the world. Image recording and several types of
visual manipulations will be introduced, a number of optical illusions will be explained
and connections between human vision and imaging systems will be made.
Andrew Hannan - The Digital Camera Market: An Overview
Buying Director, Jessops PLC
Andrew will give us an insight into the digital camera market from his unique
position as Buying Director of the U.K.'s pre-eminent high street photographic retailer.
His talk will be wide ranging covering the impact that camera phones have on the compact
camera market through to whether the end of the "pixel race" is in sight.
Prof. Geoffrey Attridge ASIS FRPS - Which Colour Spaces?
University of Westminster
Professional colour reproduction is frequently discussed in terms of colorimetric
information based on, particularly, CIE colour spaces and diagrams. This presentation
explains the basis of colorimetry, its use in comparisons of image displays including hard
copy and monitor screens, and its relevance to colour management.
Elizabeth Allen - Imaging Workflow
University of Westminster
This talk will be a discussion on some guiding principles in determination of
workflow; for example interpolation, colour management, choice of file format from capture
to output, image quality versus workflow efficiency, image processing pipeline and
requirements of different imaging applications.
Dr. Graeme Awcock - Pictures From Space: An Introduction to Multi-Spectral Remote
Sensing (700kb PDF)
University of Brighton
Satellite-borne remote sensing instruments now provide an established and
demonstrable capability to collect invaluable data from the 'high-ground' of space.
Furthermore, a wealth of data is available from the 1970s to the present day to permit
study of changes in land use and the properties of the Earth's surface and its atmosphere;
this is a critical resource in developing our understanding of climate change and other
environmental issues. As we approach the start of "IR100", it is fitting, perhaps, that
much of this capability relies on sensing undertaken in the IR wavelengths. This
presentation will review the development of satellite-borne multi-spectral sensing and
introduce some applications.
Dr. Tony Kaye ASIS FRPS - "RAW" Conversion Options: Too Much of a Good
Thing? (1.8Mb PDF)
Independent Imaging Consultant
At Good Picture 2007 results from 10 different "RAW" software converters were
compared, Adobe with ACR 5.3 alone now offers 11 different camera profiles for Nikon
cameras. Three are "Adobe" profiles and eight are "camera" profiles. These "camera"
profiles were designed to match the colour appearance produced by the camera, and the
camera manufacturer's software. In this presentation we will compare and contrast the tone
and colour reproduction offered by ACR 5.3 with that produced "in camera" and via the
camera manufacturer's software, and assess how closely they match.
Dr. Alan Hodgson ASIS FRPS - What Happens When You Press PRINT? (400kb PDF)
3M Security Printing and Systems Ltd.
Ever wondered what actually happens when you press PRINT on your computer? This
presentation will explain the process, broken down into the 3 decision groups taken in the
background by your printing system.
