DIY Photoshop 101
Dr. Rob Jenkin, Cranfield University
We all rely on the marvellous results produced by packages such as Adobe Photoshop™ and Paintshop Pro™ – 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!
Good Picture 2003: Assessing the Quality of Digital Images and Systems
Image Quality: Meanings, Minefields and Mastery
Professor Ralph Jacobson, University of Westminster
An essentially non-mathematical overview of various issues relating to image quality, including working definitions, transferability of concepts from conventional to digital systems, physical (objective) and psychophysical (subjective) measures.
Digital Cameras – Lovely Colour Isn’t It?
Professor Geoff Attridge, University of Westminster
An outline of the reproduction of colour by digital photography, addressing the characterisation of digital cameras in terms of the “colorimetric accuracy of colour reproduction”. Important limitations of colour reproduction are also be identified.
Digital Cameras – Choosing and Using
Dr. Mike Pointer, National Physical Laboratory
A review of the major decisions that must be made in order to choose a digital camera. The issues described include the concepts of pixels, resolution and compression, as well as taking the picture, downloading the stored image, and viewing and editing the image.
Archival Image Quality, Storage and Migration Strategies (0.9Mb Acrobat file)
Dr. Sophie Triantaphillidou, University of Westminster
An introduction to the processes involved in the digitisation, display and storage of image collections and archives. Description of device characterisation and calibration procedures are discussed, along with the important issues of image encoding, file format, physical storage and data migration.
