Many long-term geomagnetic observation results recorded on photographic bromide paper have not yet been fully digitized. To that end, we developed a method to automatically convert photographic records to one-minute digital data. We applied our method to the observation records of Kakioka Magnetic Observatory and confirmed that the resolution of time and amplitude could be greatly improved by n...

This paper presents a case study on card-based versus device-based (Apple iPad) reminiscing using photographic images. Nineteen older people participated in this study and results show that there is no significant difference between traditional and device based reminiscing of photographic images. The authors’ position on reminiscing focuses primarily on helping to understand people's current pr...

This paper addresses digital techniques used to automatically correct those color photographs whose range of trans-mittance densities is too large for visually acceptable image reproduction. The rst step consists in calibrating the image acquisition devices, and results are shown for two diierent models. Then, we present a method inspired by photographic techniques that uses modiied binary mask...

A method based on theory has been developed for the photographic quantitation of fluorescent substances. DNA stained with ethidium in agarose gels is used as an example of an application of this method. In the course of developing this method we have demonstrated that the empirical methods employed by others authors can give rise to large systematic errors. We have also developed an approximate...

Clinical photography in the field of oculoplastic surgery has many applications. It is possible for clinicians to obtain standardized clinical photographs without a studio. A clinician photographer has the advantage of knowing exactly what to photograph as well as having immediate access to the images. In order to maintain standardization in the photographs, the photographic settings should rem...
