The Negative Scanner

This lockdown period, and work from home, have given us less room to put up any further excuses, but to take up the household cleaning activities. Not the regular dusting, but the one where all the stuff gets defragmented. I usually used to take up such activity once in a year, during Diwali. But, for a change, I opted to defragment my cupboard, which was surviving only on dusting, for years till now. And, to my utmost surprise, I found this negative slide converter, used in the 90s for scanning negative film roll. Today's digital young world will hardly know about this.



Photo slides, technically known as reversal films, are a type of photographic film that produces a positive image on a transparent base. Slide film is processed to form dia-positives or transparencies, rather than prints or negatives. A photo slide is a specially mounted transparency, designed for projection onto a wall or screen. This makes it ideal for viewing photos at a larger scale and in a group setting.

In the early days, slide projectors relied on a sliding mechanism to pull given transparency out of the side of the machine and replace it with the next one. This is where the 'slide' in slideshow comes in.

Modern slide projectors typically use a carousel that holds a number of slides. There is a rotating mechanism involved here with the projector automatically moving to each slide, picking it out of the carousel, and placing it in the front.


The advantages of slides are that the images can be viewed as is, without the need for processing or printing. Slide images contain a high level of detail - including vibrant colors, contrast, sharpness, and fine grain.

He keeps keen passion towards photography, travelling to historic places, trying different food at various restaurant & attending Mumbai's all happening exhibition events. His hobbies are collecting keychain from every journey (currently having 118 nos), some are gifted too.


In his first job in a studio in 2004, he used to scan and retouch the images. Nikon scanner was used for this process, and it was the last era of photo film because the digital camera was launched in the market and people have started using it, the memory card was much preferred than the roll. Hence, finding this vintage out was just like a journey back in those years for Dhiren.
