              Eyes play very important role in our life by letting us see beautiful environment around us. Right now you are reading this post because of them only. The light in front of us enters our eyes and after analyzing it, we get to see things.  Same important work is done by lenses in cameras. Sensor collects light falling on it, but lenses concentrate the light on sensor. This post describes importance of lens in photography.   When do we take photo? When we want to capture the moment happening in front of us for ourselves or when we want to share it to somebody else. The work of lens starts from here. Actually the ‘photo taking process’ starts with the lens.   There are some parts of lens which we have to study to know working of lens. They are Glass elements, Aperture, Image stabilization system, Auto focus system, Focus ring and Zoom ring, lens cap, lens hood, weather sealing and Tripod or lens collar. Let us ...

Because in every camera and mobile advertisements, it is highlighted in big and bright fonts that those gadgets have higher megapixel counts. All the companies are in a race of providing higher resolution photos to the customers. 21 mp, 48mp, 64mp, even up to 108 mp, largest of known mobile phone resolution at this time, July 2020.       But do we actually need these many pixels? What are advantages of having higher megapixel sensor? How it affects image quality and usability of a photo? All these questions will be answered in this post.

     What’s use of the body without a SOUL? They both exist because of each other. Same is the case with camera and it’s sensor. Sensor is the SOUL of camera. Without it, camera is just a toy. Let’s take a deep look at this subject in this post.      We know that lens does the work of concentrating incoming light on the sensor. Mirror and prism assembly lets us see that light. Processor and memory card is ready to work on light. But if there is no sensor in the camera, then how the incoming light will be saved? That’s why sensor holds utmost importance in photography.  Does this mean that ‘it’s possible to not have other parts in the camera?’ If thought on deeply, it is actually like that. Because the word photography itself means ‘A painting drawn with light’. May it be good or bad, it will still be a photograph.  Consider following points for this. - If there is no lens, light will not be concentrated on sensor, but light will fall on the sensor...

' What’s a big deal in taking a photo. After all it’s just clicking.’        I have heard this sentence thousand times, if not less. I don’t know why people think that the photographer just have to click the button to take the photo. May be because they don’t know which and how many processes take place inside a camera to take a single photo. So let’s get detailed information about this.       Following are the parts of camera, which carry out various processes in the camera, starting from entry of light through lens, all the way up to storing the final image.  1. Lens 2. Mirror and prism (Only in case of DSLR camera) 3. Screen 4. Shutter mechanism 5. Sensor 6. Processor 7. Storage space Now let’s see all of these points in detail. 1. LENS      Lens is nothing but a number of concave and convex glass elements, stacked together in various groups. Light passes through all the glass elements and reach to the sensor when the camera...

You must read this before buying a new camera for you.

       If anyone wants to jump into photography business or just wants to take better photos for himself only, the basic and first question he/she gets is ‘Which camera should I buy?’ Generally, most people only know DSLR camera and they think that once they get that, photos will look better automatically. But that’s not the case. There are some other types of cameras as well. This post is regarding the same topic.     Based on working of the camera, there are two main types. 1. Instant camera 2. Digital camera INSTANT CAMERA This type of camera works just as it’s name suggests, Instantly. After the picture is clicked, we get print of that photo instantly. In these cameras, there is a provision for storing chemically coated papers just behind the lens. When the photo is clicked, the light coming from the lens falls on the paper and a chemical reaction takes place on the paper, due to chemicals present on it. After that the photo gets printed on that paper...
