EXPOSURE STOP IN PHOTOGRAPHY

Image
  The ‘stop’ is a measurement of exposure, which is used to denote the change in the value of any of the three elements of the exposure triangle. As we all know, the exposure is controlled by aperture, shutter speed and ISO sensitivity and this is the reason why these three form the exposure triangle. Though it may sound really complicated, but trust me once you understand the basics of it you shall be well versed with the term ‘stop’. All you need to understand is that a stop is related to the change in the exposure value, so be it because of shutter speed, aperture value or the ISO value. Increasing the exposure by one stop means that you are allowing double the amount of light to enter the camera. Similarly, decreasing the exposure by one stop means that you are letting in half the amount of light.

The Light Meter

           What is a Light Meter? Light meter is used to measure the amount of light. It is used to  determine the proper exposure for a photograph.  The meter will include either a digital or analog calculator which displays  the correct shutter speed and f-number for optimum exposure, given a certain lighting situation and film speed. TYPES OF LIGHT METER Built-in Camera Light Meters, also known as Reflected meters  are used by aiming at the scene through the camera, and measure the amount of light that the subject in the scene reflects. Which means that these meters can only guess the amount of light hitting the subject. The reflected meters are designed in such a manner that they are bound to see the subject as mid-gray, neither as white nor as black. This might work great in many situations, but many real life subjects have varied reflective qualities. For better understanding, let’s take the case of two situations: When the light falls on a white subject, it will reflect a lot of

Technique for Sharp Images

Image
 What is Sharp Image? A sharp image is one where the subject of the image—or the bits of the subject you want—are in perfect focus with every detail crisp and clean. One of the things that makes photography frustrating is softness and blur in pictures.  Sharp photos  are much more appealing than soft images. It is very disappointing when you take a picture of a special moment and images come out soft/blurry or out of focus. So, in this article, I will go through the techniques I use to make sure that my images always come out tack sharp. Let’s start with the reasons why an image might come out blurry: A long  shutter speed  can capture camera shake, which would produce a blurry image Your subject could be moving and causing  motion blur , made worse by a long shutter speed Poor  focus acquisition  would result in a soft image You might have a bad lens or a lens that is not capable of producing sharp photos Your  ISO  could be set to a very high number, resulting in lots of noise and lo

Understanding F-Stop

Image
 What is F-Stop? F-stop is  the number that  camera shows you  when you change the size of the lens aperture. You might have seen this in your camera before. On your camera’s LCD screen or viewfinder, the f-stop looks like this: f/2.8, f/4, f/5.6, f/8, f/11, and so on. Sometimes, it will be shown without a slash in between like f2.8, or with a capital “F” letter in the front like F2.8, which means the exact same thing as f/2.8. These are just examples of different f-stops, and you might come across much smaller numbers like f/1.2 or much larger ones like f/64. What Does the “f” Stand For? The “f” stands for “focal length”. When you substitute focal length into the fraction, you’re solving for the  diameter of the aperture blades  in your lens. (Or, more accurately, the diameter that the blades appear to be when you look through the front of the lens). For example, say that you have an 80-200mm f/2.8 lens fully zoomed out to 80mm. If your f-stop is set to f/4, the diameter of the apertu

Do Megapixel Really matters??

Image
  What are Megapixels? One megapixel is equal to one million pixels in an image. You can easily calculate the megapixels of your camera by looking at the width and height of the image in pixels. For example, if I click an image using my Canon 5D Mark III, I get an image of 5760 × 3840px. So by multiplying 5760 by 3840 pixels, we get 22,118,400 pixels which mean that the image that I clicked has 22.1 megapixels. How many pixels do you actually need? The requirement of megapixels depends on the final use of the image clicked by you. There are three major ways you can use your images after clicking them from your camera: View it on your monitor If you click images just to view them on your monitor, you hardly need a high megapixel camera. Suppose you own a 19-inch 1920×1080 resolution monitor, all you would need is a 2-megapixel camera to view the images clearly. So even if you would be cropping your images a bit after clicking them, you can use a 5-6 megapixel camera to view images witho

Difference Between Raw and Jpeg

Image
  WHAT IS  RAW IMAGE? A RAW format file is basically an unprocessed file captured directly through the camera sensor. The image captured in RAW format is usually dark and flat in contrast as the file is not processed at all, as in the case of a JPEG file. While viewing on your camera’s LCD screen, you would hardly find any difference between the RAW and the JPEG files. But the moment you open the files on your desktop or the laptop, you might me disappointed by the look of the RAW file because of its flat color tones and contrast. At the first look, you might fall in love with the JPEG file, but the truth is that the RAW file holds all the details ranging from the contrast to white balance. Using the RAW file, you can completely change the white balance, brightness, sharpness, contrast, etc., of the image, without degrading the quality. In order to access the RAW file on Adobe Photoshop or Adobe Lightroom, you would need to download the free  Adobe Camera Raw  plugin. Unlike JPEG forma

Some Posing tips

Image
 Here, are some photography trips  1. One Step Forward The most automatic pose when someone takes your photo is to plant your feet straight down. But, by taking one foot and stepping forward it not only gives your body natural curve,  it also gives the picture movement and interest. 2.  Move The Shoulder For a real posing  , utilize your shoulders. This looks amazing when you’re being shot portrait-style from the side – and it’s something we often see models do. If you pay any attention to beauty or fashion editorials, models always bring their shoulders slightly up and forward towards their chins
