DIGITAL CAMERA MODES

By -


DIGITAL CAMERA MODES can be defined as camera controls that are used by the photographer before shooting the subject.

This effect the things like main setting of aperture,shutter speed and ISO and help to get better exposure of in an image

Digital camera modes can be changed using different camera modes icons.Most Digital Camera have this on the top of the camera body.



DIFFERENT CAMERA MODES IN DIGITAl PHOTOGRAPHY

  • MANUAL CAMERA MODE
  • PROGRAM CAMERA MODE
  • SHUTTER PRIORITY MODE
  • APERTURE PRIORITY MODE


MANUAL CAMERA MODE

Manual control stands for total manual  control of aperture and shutter speed. In this mode we can set aperture and shutter speed to any value we want.the camera lets you fully take over the exposure controls. This mode is generally used in situations, where the camera has a hard time figuring out the correct exposure in extreme lighting situations.

Manual mode is also useful for consistency, if you need to make sure that both shutter speed and aperture stay the same across multiple exposures. For example, to properly stitch a panorama, all shots that you are trying to put together need to have the same shutter speed and aperture. Otherwise, some images will be darker, while others are lighter. Once you set the shutter speed and aperture to the values of your choice in manual mode, your images will all have consistent exposures.




 PROGRAM CAMERA MODE

In this mode, camera itself automatically choose the aperture and shutter speed .This mode is made if person want to click the snap quicky i.e point and shoot. The camera try to balance between the aperture and the shutter speed,increasing and decreasing based on intensity of light.

If you point the camera to a bright area, the aperture will automatically increase to a bigger number, while keeping the shutter speed reasonably fast. Pointing the camera to a darker area will decrease the aperture to a lower number, in order to maintain a reasonably fast shutter speed. If there is not enough light, the lens aperture will stay at the lowest number (maximum aperture), while the shutter speed will keep on decreasing until it reaches proper exposure.



SHUTTER PRIORITY MODE

In this mode, you can set the shutter speed of the camera and aperture is automatically selected by the camera based on the amount of light passed through the lens.

This mode is intended to be used when motion needs to be frozen or intentionally blurred. If there is too much light, the camera will increase the lens aperture to a higher number, which decreases the amount of light that passes through the lens. If there is not enough light, the camera will decrease the aperture to the lowest number, so that more light passes through the lens. 




APERTURE PRIORITY MODE

In this mode we can set the the  lens aperture,while the camera automatically picks the right shutter  speed for perfect expose of image. 

You have full control over subject isolation and you can play with the depth of field, because you can increase or decrease the lens aperture and let the camera do the math on measuring the right shutter speed. If there is too much light, the camera will automatically increase the shutter speed, while if you are in a low-light environment, the camera will decrease the shutter speed.

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 s...

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 ...

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...
