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 light, which will be read high by the camera light meter. In order to make it mid-grey, the camera will underexpose the scene.

Similarly, when the light falls on a black subject, very less amount will be reflected back, which will be read low and the camera will overexpose the scene.

Incident meters are used by aiming directly at the source of light and measures the amount of light falling directly on the subject, has nothing to do with the reflective quality of the subject. You can have better control of lighting in the scene you are planning to click by measuring all the light sources lighting up the various subjects in your scene.

An incident meter helps in achieving correct and accurate color tones and contrast by measuring the intensity of light falling on subjecr, regardless of the reflective quality of the subject. Which means, the subject that is darker or lighter than grey will appear as it is and will not be compensated to mid-gray tone. which concludes the incident meter help the photographer to accurately expose the scene for most of the lightning situations.

Understanding ISO Sensitivity

By -

ISO refers to the senstivity -the signal gain-of the camera. In simply, ISO is simply a camera setting that will brighten or darken a photo. As you increase your ISO number, your photos will grow progressively brighter. For that reason, ISO can help you capture images in darker environments, or be more flexible about your aperture and shutter speed settings. WHAT IS BASE ISO? The lowest native ISO on  camera is  “base ISO”. This is a very important setting, because it gives you the potential to produce the highest image quality, minimizing the visibility of noise as much as possible   ISO VALUES ISO 100 (low ISO) ISO 200 ISO 400 ISO 800 ISO 1600 ISO 3200 ISO 6400 (high ISO) LOW VS HIGH ISO NOISE VISIBILITY   Take a look at the comparison below. Pay attention to the level of noise (graininess and    blotchy colors) in the images: The difference is clear – the image at ISO 3200 has much more noise than the one at ISO 200 (which I brightened with a long shutter speed instead). This is why

Difference Between Raw and Jpeg

  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

What is Shutter Speed??

WHAT IS SHUTTER SPEED? Shutter Speed is the length of time the camera shutter is open,exposing light on to the camera sensors. Shutter Speed is one of the three elements of Exposure Triangle that are responsible for correctly exposing the photos. Shutter speed decides whether to freeze the subject in your frame or to capture a long exposure moment. In this blog post, I am going to shed some light on what exactly the shutter speed is and how you can control it to click various kinds of photos. How Shutter Speed Is Measured?? Shutter speed are measured in fractions of a second. Most modern DSLRs and mirrorless cameras can handle shutter speeds of 1/4000th of a second at the fastest, while some can handle even quicker speeds of 1/8000th of a second and faster. On the other hand, the longest available shutter speed on most DSLRs or mirrorless cameras is typically 30 seconds. You can use a longer shutter speed by using external remote triggers, if necessary. Types Of Shutter Speed 1) Fast S
