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.

sRGB vs Adobe RGB colour space explained

Digital images are everywhere, both offline and online. Each digital image is made up of a large number of square sized individual pixels. Zoom into an image at 2000 % or more in any of the viewers, you will see these pixels. Here is an example:

In order to categorize pixel colours, RGB and CMYK are the two widely used colour models. According to the RGB colour model, each pixel colour can be considered as an addition of different shades of red/green/blue light. These light shades are calculated according to the bit depth of the image. Jpeg images are usually 8 bits per colour channel (red, blue or green), which means 2^8 ( 256) different shades of each red/blue/green colour are possible. Few examples to make it clear how different colours shades are represented:
Red: (255, 0, 0)
Green: (0,255,0)
Blue: (0,0,255)
White: (255, 255, 255)
Black:  (0,0,0)

What does CMYK do? It is a subtractive colour model for printing purposes and stands for Cyan, Magenta, Yellow and Black. According to …

Digital photography histogram explained for better photos

The ability to read histograms in digital photography is an excellent skill that every photographer should have. Getting a properly exposed shot is crucial when it comes to photography, and using the histogram is a solid way to achieve it. That 2 to 3 inch LCD screen located on digital cameras is only a quick way to look at the photo exposure and its details. In harsh lighting or vivid ambient lighting conditions, it can prove to be misleading to the human eye. Sometimes the LCD brightness level can also create issues with judging the exposure of a shot. So what does histogram explain about an image? How can histogram help you to take better images? In this beginner-friendly post, I will try to answer these questions. You can consider it as a tutorial or cheat sheet for digital photography histograms.
Photography histogram image examples: The histogram is basically a mathematical way of representing data, and it applies to digital image information too. In digital photography, histogr…

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…
