Transition from Analogue to Digital Era

A way long, the whole concept of photography has changed drastically. The whole system of negative roll has been taken over by the digital era. Here we will discuss about what has changed and what not.

Starting with the concept of photography, the basics are still the same. The whole photography techniques moved around the Aperture, Shutter and ISO. The things which changed from analogue to digital is the medium at which the photo is being captured i.e Negative rolls or Glass Plates to Electronic Sensors.

Earlier the Negatives of different size were available so as CMOS sensor now. Very common size of negative used and familiar to the general public is 35mm(24x36mm) negative film and the maximum size available known to professionals only were “20inches x 24 inches”, In between there were many different size of negatives available in past – 4x4cm, 4x6cm also called 120mm film, 5x7inches glass plates.

Now, for the same work DSLR Camera or any electronic camera have CCD/CMOS Sensors on which the image is captured. These sensors are also of different sizes and consists of a smaller unit called pixels, the more the pixels the more will be the details in the photograph. Each Pixel is made up of 3 color bars – Red, Green, Blue.

The Camera which have a sensor size equivalent to 35mm is categorised as a Full Frame Camera, and the camera those have a sensor size less than a full frame is known as Crop Frame Camera. There are 100s of camera models available from different brands with Crop Frame Sensor. There are limited no. of Full Frame Cameras which are now ruling the market from different brands. The Full frame camera comes under the Professional camera from each brand and are most used for photography purpose. There are now hybrid camera available in the market which offer both the operations of making video and capturing photos with professional settings and output.

The Electronic sensor available of maximum size in some commercial camera is 8×10 inch in LargeSense LS911 Camera.

Focussing System

The Focussing system has also been changed from manual to very fast & automatic. Earlier the focus and aperture settings were manually set from the different rings present on lens. Now the whole focussing system is converted to electronic and automatic system which gave a revolution in photography by giving birth to so many categories of photography specially where fast focus was necessary eg. sports photography, Wildlife photography. With Fast and Automatic focus system we are now able to capture any subject with more precise focus results in more sharp and detailed images.

Although the 35mm negative film was having a resolution equivalent to approx 40 megapixels of electronic image. So the details we also good in the analogue photography also, the only thing changed is lens are now more precise and fast.

Image stabilization

With the electronic era one more concept came into trend i.e. Image Stabilization/Vibration Reduction. This is the method through which the camera shake can be adjusted upto an extent. Now some lens are able to handle that upto 5stops Image Stablilization which means with this option if you are are to shoot a picture at a SS-1/2000 then you are now able to click the same with image stabilization ON at SS-1/60 also, the image will not have a shake in the final result. The Image Stabilization works for the Camera shake reduction not for the subject movement blurs or shakes. Most of the Zoom Lens coming into the market are generally having at least 1 or 2 stop of image stabilization.


Earlier in analogue photography cameras the widest available aperture was 2.5 or nearby, but now a days in the electronic era, there are lens available in the market with an aperture of 1.1 as well.

Speed of Camera

The image taking capability of the cameras has drastically changed as of now the DSLR camera can shoot photos at upto 20 frames per second or more on continuously shooting the images.

So, this was all about the differences came in the equipments from Analogue to Digital Era. There is a lot more in detail.
