For instance, the term mega pixel is always referred whenever this gadget is discussed
. It will be clearly understood that mega pixels have nothing to do with the grade of photos shot in this camera. It is a factor that enables enlargement of photo prints. If the photographer wants to take out large size printout of the photos, it is necessary to opt for a camera with higher mega pixels.
To obtain a 5 x 7 inch printout, camera needs 2 mega pixels of resolution. But those who are not trained with the technicalities will have wrong conception that the quantity of mega pixels is the factor that determines the grade of photographs. Similarly optical and digital zooms are very often confusing features to many camera shoppers. Even though both these zooms work together, it is optical zoom that contributes towards better display quality. Digital zoom helps in enhanced focusing. The camera with both optical and digital zooms is preferable, but optical zoom is more relevant.
Another significant characteristic in a digital camera is its memory. Inexpensive cameras have built-in memory to store the snaps. But memory cards are more popular which are removable as well as up gradable. In the market there are various types of memory cards available. Compact Flash, Smart Media and Sony Memory Stick are a few among many types of memory cards widely used in this gadget. To understand the significance of the memory card the user should know that in a digital camera with one mega pixel resolution a 16MB memory card will be able to store 40 pictures.
The optical view finders are included in all digital cameras. But LCD screens are more innovative. Photographers can view the object on the LCD screen before and after clicking the camera. It is the most advantageous feature of it which enables deleting of unwanted photos then and there. However, LCD screens require additional battery power. Another version is the electronic view finder which is gaining popularity among the users.
Re-chargeable batteries are a better option although they are costly. Some of the digital cameras will have AC adapters to facilitate supply of power directly from mains. New digital cameras provide various facilities like built-in pop up flash, auto focus and automatic image stabilization. Size and weight of the camera varies and shoppers have to decide about them in accordance with their tastes and convenience.
