How to Choose Camera while buying

Many kinds of digital cameras are available in the market today. All are equipped with a variety of features, these make it easier even for an amateur to click great quality picture.

Given the many options to choose from, findings the right camera within your budget can be daunting. A good way to choose a camera is to go for the features that give you a superb image quality while enhancing your photo imaging experience.

Megapixels

The resolution in megapixels – MP tells how much you can enlarge your picture quality. The choice of megapixels truly depends on what you would like to do with your photos.

The more the pixel count, the sharper the photographs in larger size. A higher megapixel count also gives you the flexibility to crop and print a section of the whole picture.

A 5MP resolution is enough to take a sharp 20x25 cm2 print. Likewise, 8 MP are enough to take a sharp 28x36cm2 print.

Image Sensor

The image quality also depends on camera sensors and lenses. Digicams with large sensors and high quality lenses take crisp shots, regardless of MP count. So, before buying a camera, see how big its sensor is.

Shutter lag and Startup time

To capture fine action shots like movement of wildlife subjects, a small shutter lag is beneficial. Shutter lag is nothing but the delay between triggering the shutter and actually taking the photo. On average, shutter lag is up to half a second in today’s camera. In high-end point and shoot camera, it could be almost a quarter of a second.

So before buying a camera, check how long it takes to capture its first shot.

Size, Weight and Design

Digital SLR cameras are usually bulky and heavier than other cameras. Small camera work best in auto mode only as they do not give any the flexibility of manual control of shutter speed and other features. Also, their size can make them difficult to manoeuvre, as the buttons are few and small.

Zoom lens and image stabilization

Optical Zoom means actual zoom done by the lenses. Digital zoom simply increases the size of the picture display without increasing any detail. The zoom range and image stabilization depend on the lens of the camera.

3x optical zoom means you can get three times closer picture of the subject than seen with your eyes. There are options of ‘W’ and ‘T’ which help you in manually controlling the optical zoom. ‘W’ stands for ‘wide-angle’ and ‘T’ for ‘Telephoto’ (magnify).

Storage

Cameras have inbuilt flash memory but their storage space is limited. So, you have to buy external memory cards like CompactFlash, Secure Digital (SD) or Secure Digital High Capacity (SDHC). The storage capacity depends on the space of the card.

Battery life

While catching important movements of your life, you don’t want the camera to go dead. So, the battery life is one of the important factors while choosing a camera.

Video recording

Cameras these days are video-enabled. To capture good-quality videos, check whether you can autofocus while shooting or not. Also, check video-editing software and memory card specifications. You would require an SDHC card for high-speed video capture.

Latest Trends

Check the latest trends of technology in cameras and which camera is more popular in the market that covers your budget. There are many different technologies that make your pictures more bright, colorful, and 3D technology in cameras are available.

Buzzer interface with 8051 microcontroller

Buzzer  is a electronic device that converts the electronic signal into buzzing noise, that is applied to it. It can be used as electronic bell or as quiz buzzer in many applications around us. Here, i world like to discuss the interfacing of a small buzzer with 8051 microcontroller and how different projects can be constructed. Buzzer Interfacing: This project shows the interface with AT89S52 microcontroller to a buzzer. When a push button is pressed, the buzzer will get ON and OFF ( number of times set in the code ) and then stops. Circuit Diagram: - The port P1 of the microcontroller is connected to buzzer. This type of connection is possible, if the current requirements of the buzzer is not more than 20mA. The output is in current source mode so that buzzer will turn ON when the output of the port is logic LOW. Switch is connected to port P3 which remains at logic HIGH by pull up resistor.  Code: #include "REG52.h" #define buz P1 sbit SW=P3^0; long i...

Comparison Chart Between 8051, 8052, 8031and 8751

8051 is a popular 8-bit microcontroller and has been used in many applications since Intel introduced it. Many 8051 architecture are produced by Triscend, Intel, Atmel, Philips, Infineon (Siemens), ISSI, and Max Corp. Today, 8051 microcontrollers may not be popular but, the 8051 architecture is still popular and employed in thousands of embedded applications. This 8-bit architecture has been different segments such as 8052, 8051, 8751 and 8031 . 8052 is the super-set of 8051 and 8031 is the memory-less microcontroller hence, it has interfaced with external ROM. Whereas, 8751 chip has only 4Kbytes of on chip UV-EPROM. Everyone knows about the general 40-pin microcontroller i.e. 8051 introduced by Intel in 1980s and consists of serial communication pins, Timer, Interrupts, RAM, ROM. It has 4 ports and each port has 8 pins, total 32 pins and other 8 pins for other purposes. 8052 is the super-set of 8051 that consists of 8K bytes of internal RAM (4K in 8051), 256 by...

Different ways to generate delays in 8051

The delay length in 8051 microcontroller depends on three factors: The crystal frequency the number of clock per machine the C compiler. The original 8051 used 1/12 of the crystal oscillator frequency as one machine cycle. In other words, each machine cycle is equal to 12 clocks period of the crystal frequency connected to X1-X2 pins of 8051. To speed up the 8051, many recent versions of the 8051 have reduced the number of clocks per machine cycle from 12 to four, or even one. The frequency for the timer is always 1/12th the frequency of the crystal attached to the 8051, regardless of the 8051 version. In other words, AT89C51, DS5000, and DS89C4x0 the duration of the time to execute an instruction varies, but they all use 1/12th of the crystal's oscillator frequency for the clock source. 8051 has two different ways to generate time delay using C programming, regardless of 8051 version. The first method is simply using Loop   program function in which Delay() funct...
