The above photograph shows a portion of JUPC’s archive of Colour Transparency or Positive Film Slides made throughout the club’s history of over 50 years. The content of these slides range from images of Jadavpur University to photos of cities like Varanasi, Lucknow, Delhi, to pieces of still life and street photography mostly done by our ex-members. These slides have helped us, as the current generation of members, in understanding the various transitions the club has gone through over the past half-century with respect to its practices and ideas related to photography. Further, it can be stated that the popularity of positive slides have always been quite high when it came to the clubs of Jadavpur University, owing to the fact that the JU Mountaineering and Hiking Club has also maintained a similar archive with an even greater number of slides made over more than 50 years. Colour Transparency or Reversal Film is a type of photographic film that is used to produce a positive image on a transparent base. The advantage of this kind of film lie in the fact that exact same image is obtained on the film as what is seen through the viewfinder of the camera. Slides are specially mounted positive transparency films which are intended for projection purposes. Most of the slides shown above were developed by the renowned Bourne and Shepherd Studio in Kolkata and have 35mm positive films mounted in them.
