What are the different types of image stabilization options in cameras?

There are two types of image stabilisation type in cameras. They are
  • Optical Image stabilisation: optical image stabilisation is hardware based. So the camera senses the sake and immediately shifts either the lens elements or the image sensor so as to compensate for its movement.
  • Digital Image stabilisation: Digital image stabilisation is electronic based. So no physical shifts occur within the camera. Here the camera's sensitivity is increased to speed up the shutter, thus offsetting blur. However, the higher the sensitivity is set for the camera, the greater the noise which can compromise the image quality.

Image stabilization feature in cameras uses special sensors in order to detect camera shake and counteract the effects of this shaking. It is very good in retaining crisp edges in photos which can tend to blur like the long distance shots taken with zoom or photos taken in low lighting conditions

For camera how much zoom is ideal?

Most cameras nowadays have at least 3x zoom which is usually enough for your everyday photos.

Higher zoom like 6x,10x,20x or higher is required when you want to take a picture while being quite a bit of distance away from your subject. But do remember that an additional zoom also means more shaking since an increase in zoom can increase the effects of the camera shake which would make your photos to be blurry. So keep an eye out for optical image stabilisation features along with your zoom since it can counteract the effects of shaking to give very smooth crisp and detailed images.

How is an optical zoom different from a digital zoom?

An optical zoom uses the zoom lens. It is the same as it is in a traditional camera which uses the lens glass to magnify an image before it reaches the camera's image sensor.

Digital zoom meanwhile is a digital tech that takes a real optical image and then zooms the image by zooming every pixel and using interpolation. Interpolation basically means that fake blocks of colour are added to fill in any gaps in the final image. Digital zoom decreases the clarity and sharpness of the image and the images get pixelated once you start zooming.

Why is that in some cameras, 2 different pixel value is shown in the specification?

There are manufacturers who publish 2 different pixel value for a camera. They are not fooling the customer by doing this, though. They are just stating a fact.

But there is a slight difference, though. One of the values is called the actual pixel count which refers to the number of pixels on the sensor on the camera. the value is the effective pixel count which refers to the number of pixels that is used actually when a picture is taken since not all pixels on the sensor is used for picture information.

You will need a card with a high memory. In addition to this, keep a spare card with you as well. Coming to the speed class it is essential that the photo is immediately transferred to the memory card. So ake sure that your memory card has a speed class of at least 6 or higher.

What are the factors that I should look into before buying a memory card for my digital camera?

Some important factors that you need to look into when buying a memory card for your camera are

  • Capacity: Capacity is measured in gigabytes. Some commonly used card capacities are 4GB, 8GB, 16GB, and 32 GB. Of course, the number of pictures you can store would depend on the resolution and file format. But even a 4GB card can hold a few hundred photos.

  • Speed Class: This refers to the amount of time that is needed to for a photo to transfer to the card once it has been taken. The thing to note here is that you won't be able to take another photo until the current photo file is written to the memory card. This is disadvantageous if you do a lot of continuous shooting. So you will also need to go for a higher speed class.

Other than the above you will also need to look into the kind of camera that you have, the photography you use and how often you take pictures.

Why do some cameras have both an LCD screen and viewfinder?

Camera's have an LCD screen since it makes it easier to frame a shot. But there are times when the glare from the sun makes it difficult to compose pictures from the screen.

It is in times like this that the advantages of the viewfinder shine through. Additionally, when you frame a shot with the help of a viewfinder, you can hold the camera more steadily in addition to preventing an accidental camera shake and blurry pictures. It works well for a zoomed it shot as well, making sure that the shot remains stable. Lastly, when you take a photo using a viewfinder, you also save battery power.

It helps you take photos under different kinds of shooting condition through its different preset exposure settings. So you can notice scene modes like Portrait, landscape, Sunset, Fireworks etc. So when you to take a photo in these situations you just need to select the correct setting and the camera will do the rest of the work like choosing the focus, shutter speed, aperture, white balance, flash options etc. So anyone would be able to take good quality photos even in difficult settings with a click of a button.
