CCD vs CMOS image sensor based DSLR camera

Just like the battle of Nikon vs Canon or Canon vs Sony, few people love to talk about the versus battle when it comes to photography and videography. There are endless versus topics where you can compare nearly everything starting from DSLRs to video stabilizer rigs and what not. I believe ultimately it all boils down to your own preference and needs. 
What is CCD? What is Image sensor? Remember, CCD image sensor was the leader if we go back by 10-12 years of photography time. Yes, all we could hear was Kodak and Fuji CCD sensor cameras as there were not many CMOS sensor based cameras. The CMOS technology came later than CCD technology. Someone on my Facebook page recently asked me if CCD sensors are better than CMOS sensors?  Coming from electronics background, I know what CCD sensors are and how they work but I have never used a camera with CCD Sensor.  After a good 1-2 minute pause, I typed a few words of technical jargon. Pretty sure the person who asked me this question did not understand any of what I said as they expected a Yes or No reply. So I thought of writing a post dedicated to the same question.

Without going into too much technicality of how they basically work, I will try to explain quick factual tidbits and differences between CCD and CMOS sensor cameras. A photographer or videographer wants better content and that's what matters. For the curious minds like me, this post would offer something more. Let's start with a few quick facts about CCD image sensor based cameras first: 
-Stands for Charged Coupled Device.
-CCD Cameras were the original choice of videomakers back in the days. Even for still photos, Kodak and Fuji were the names. 
-Expensive to manufacture.
-Consume more electricity than equivalent quality CMOS Sensor camera. 
-Uses Global shutter which means the entire photo is taken at once, unlike CMOS sensor based cameras. In CMOS sensor based cameras, the image is taken from top to bottom. 
-Example: Leica M9, Nikon D80, Nikon D3000, Pentax K10D, Panasonic FZ40, Pentax 645D, Pixim Seawolf, Sony SuperHAD 600 TVL.

Coming to CMOS sensor based cameras, it is a brand new technology and has evolved at a very fast pace as CMOS chips are cheap to manufacture. Here are some points that make CMOS image sensor based cameras different from CCD cameras:
-Stands for Complimentary Metal Oxide Semiconductor.
-Cheaper to manufacture. That's why GoPro and most modern cameras have CMOS Sensors. 
-Faster data transfer.
-Less power consumption. 
-The usual problem of rolling shutter, especially noticed by videography folks. 
-Example: All the modern day DSLR cameras. Canon 6D, 6D mark II, 5D mark II, 5d Mark III, 7D, 5d Mark IV,  Nikon D750, D810, D7200, NIkon D7500, Nikon D3400, Sony A7, A6300, A6500, A6000, etc.

CMOS vs CCD Sensor
Both sensors do the same task of capturing light and converting it into electrical signals. Unless you are getting very serious about videos (FPV, RPV, Security cameras), the extra money for CCD is not worth it. If you found this post helpful, share the photography love by sharing this post.

Canon CR3 raw format guide

A raw image file is like a digital negative without any lossy compression and minimal processing applied to it. A digital camera shooting images in raw format provides output in the best possible quality, which means files are larger in size and take more space. The benefits offered by shooting raw format overpowers the slight storage hassle though. Few of the well known raw formats include CR2, NEF, RW2, RAF, PEF, ARW, etc.  In this post, we will talk about the new compressed raw format introduced by Canon starting with its mirrorless series of cameras.

History of Canon raw formats
Back in the early 2000s, Canon cameras produced raw photos in CRW format. Example of cameras shooting in CRW include Canon D60, Canon D30, Canon 10D, and Canon EOS 300D. Most of the cameras released after the year 2004 shoot raw photos in CR2 format. Examples of CR2 format Canon cameras include 350D, 6D, 7D, 5D, 5D Mark II and many more.
In 2018, Canon introduced its new mirrorless camera known as the EOS …

Relation between ISO, shutter speed, aperture and light in photography

Photography is a word having Greek roots, which basically means "drawing with light". When I started doing digital photography a few years ago, this did not make sense to me at all. How can you make a picture just using light? Only light matters? My pictures were either black or completely washed out all the time, but I didn't feel like giving up. It took me a fair amount of time to understand controls such as shutter speed, aperture and ISO which was the outcome of non-stop reading and a lot of mistakes. Coming back to the concept of light, it started to make sense after attending a film photography workshop. The dark room with very dim or near to zero red lights was a whole new point of interest. My partner and I made a pinhole camera out of a pumpkin. 
The workshop made me understand how important light is when taking pictures, and the rules apply to both film and digital photography. Basically, the value of shutter speed and aperture directly affect the amount of li…

Darktable vs Lightroom Classic CC

I first heard about Darktable software in 2016 and actually was quite fascinated with the name itself.  Within a few hours of hearing about it, I went to the official Darktable website and downloaded it on my Linux machine. Have been using it for quite a while now alongside Adobe Lightroom Classic CC and hence decided to write this small review post. If you are looking for a free Adobe Lightroom alternative, this might be or might not be for you depending on what you need.  Darktable is a free open source post-processing software which can do non-destructive RAW photo editing and photo management. Non-destructive means it does not change the original RAW file, all the edits are written to a sidecar file. It has evolved through so many phases of bug fixing and operating system compatibility. The latest version is available for Linux, MacOS, and Windows. Being an open source software it doesn't surprise me that it is available in 21 language translations. That's the power of op…
