Imaging Science Group Committee 2025
Dr Mike Christianson ASIS FRPS
Chairman and Financial Officer
Following his time at University, where he studied chemistry, Mike joined the Research Division at Kodak Limited in Harrow and worked there for over 30 years before his retirement. During his career he was intimately involved with conventional silver halide photographic materials in areas from fundamental latent image theory to the manufacturing of colour films and papers. His continuing interest in photography lies in the scientific and technical side of imaging.
His involvement with the RPS began in the mid 1990’s and soon after he became a member of the Imaging Science Group’s committee. During his time as a committee member he has held various posts e.g. Executive Editor of the Society’s learned publication, the Imaging Science Journal. He helped in the development of the Society’s Imaging Science Qualifications and served on the management Panel for a number of years. He has held the role of the Group’s Treasurer (Financial Officer) from 2005 to the present day. Since 2003 he has organised the Group’s continuing annual symposium “Good Picture” which has covered a huge range of topics relating to all aspects of imaging. Presently he is in his second stint as committee Chairman.
Dr Richard Stevens ASIS FRPS
Hon Secretary
Richard has been a member of the Imaging Science Group for over 40 years and has been Hon Secretary to the Group for 15 years. He studied physics at University College London and joined the National Physical Laboratory in 1967. His career was in the field of optical metrology, developing and applying techniques for optical measurements traceable to national standards. This involved a variety of imaging techniques in two- and three-dimensions including holography, interferometry and micro-optics.
Richard is also a member of BSI and ISO technical committees CPW172 and TC172 respectively, developing international standards for the optical industries. He has enjoyed photography since his teenage years when he built his own enlarger and darkroom and has been an active member of his local camera club for more than 45 years.
Dr Alan Hodgson ASIS HonFRPS
ISG newsletter editor
Alan has been a member of the Imaging Science Group for nearly 20 years and has recently taken on the role of newsletter editor. He studied Chemistry at UMIST (now University of Manchester) and joined Ilford Imaging in 1982, initially in Image Physics. He worked on silver halide technologies for camera and holographic applications but moved swiftly onwards to scientific and technical use cases. As photographic printing moved into inkjet his work also moved into this area but retained his role in the support of the Scientific Products business, including photographic glass plates.
Leaving Ilford Imaging in 2004 he started a consultancy business on inkjet and security printing. During this period he became President of both the Society for Imaging Science & Technology (IS&T) and the RPS. He has also acted as Chair of the Institute of Physics Printing and Graphics Sciences Group and ISO Technical Committee 42 (Photography). His current interests include the science underpinning the conservation of photographs and the history of photographic science.
Dr Kevin Howell ASIS FRPS
ISG web editor
Kevin graduated in Physics from the University of Birmingham in 1991, and started working at the Royal Free Hospital in London soon afterwards in a Clinical Science role. He has over 30 years of experience in the use of thermal imaging in medical applications. He gained his PhD from the University of Glamorgan in 2009 on infrared thermography for the study of rheumatic diseases, and is the current Chair of the European Association of Thermology (EAT).
Kevin was introduced to the RPS when ISG member the late Prof Francis Ring suggested he submit his portfolio for consideration for the Accredited Senior Imaging Scientist qualification. Now part-retired, he dedicates his spare time to racket sports and photography, and his helping both the RPS ISG and the EAT update their web presences.
Hoosain M Ebrahim ASIS FRPS
Hoosain attended The London Film School where he completed the Motion Picture and Television Production Course. He then attended the Polytechnic of Central London, (now University of Westminster) where he majored in Scientific Photography and Technology. He then pursued a course in Medical Photography through the British Institute of Professional Photography whilst in training at the Charing Cross Hospital Medical School.
In 1982 he was headhunted to establish the first centralised Department of Medical Illustration Department at the Medical University of Southern Africa (now Sefako Makgatho Health Sciences University) where he worked for 36 years. Services provided were AV and technical services, advisory and consultancy, training and instruction, e-learning, telemedicine, research, educational media services, imaging in the visible and invisible range to cover Medical, Dental, Scientific, Research and Forensic Photography.
He has been a member of the RPS since the mid-seventies and presented papers at both the Medical and Forensic and Digital Futures Meetings hosted under the auspices of the Imaging Science Group. He has received many awards and recognitions including the British Journal Award for “Kirlian Photography in Medicine” and the Technical Award Medal for developing a technique “Comprehensive Gait Recording in Parkinson’s Disease Patients”. In addition, he was awarded the Royal Photographic Society’s Members Award and Honorary Life Membership.
Dr Anthony (Tony) Kaye ASIS FRPS
Tony’s interest in photography started with the family Kodak Brownie 127 camera. For his 13th birthday he got a Johnsons of Hendon developing kit. A few years later he graduated to colour where he would buy Ferrania CR50 Slide film in bulk, spool it into cassettes and sell it to some of his class mates as process paid Tonichrome 50!
From the age of 16 to 24 he had student jobs working at Dollonds Photographic. He studied physics at the University of Manchester and following his BSc he moved to the Astronomy Department for his PhD where he studied photographic and hybrid systems of detecting faint light at telescopes, including a 4-week stint at the Anglo Australian Observatory where he was hypersensitising 14in square plates for use in the UK 48-inch Schmidt Telescope. During his spell at Manchester, he published 4 papers.
After leaving university he went to work at Kodak Limited from 1978 to 2006 including a one-year spell on assignment to Eastman Kodak in Rochester. During his time at Kodak, he worked mainly on the colour negative positive system in R&D departments, moving onto hybrid systems during his last few years there. During his time there he obtained 4 patents, and published over 100 internal reports. From 1986 until his retirement, he was Kodak’s Quality Leader for all colour negative films sold in Europe, Africa and the Middle East.
Following early retirement in 2006, Tony joined the RPS and has held the following positions: - Member of the RPS Ruling Council, Chair of the Science Committee and Chair of the Imaging Science Group. Due to personal circumstances Tony cannot devote as much time to the RPS as he would like but he still makes valuable contributions to the Imaging Science Group and is a frequent speaker at events. He was awarded the Society’s Fenton Medal in 2020.
Dr Sophie Triantaphillidou, ASIS, FRPS
Sophie completed BSc and PhD degrees in Imaging Science at the University of Westminster in London, UK, where she subsequently taught and led research and academic programs in imaging science for more than 20 years. She was the Director of the University’s Imaging Technology Research Group between 2006 and 2016, co-founded the Computational Vision and Imaging Technology and served as its director between 2015-2023.
