Best Digital Camera: 5 Best Cameras For Moms

Photography is an art of taking pictures. Some people use photography as an alternative to painting and drawing. Some also love taking pictures because it is the only way where two different events, the past and present, connect with each other. Through these pictures, the memories of the joyful moments people shared in those gone days come back to life. To be able to capture a thing or an event, it’s a must to have a digital camera.

Camera is a medium which records still or moving images. Since we are now in the techie world, the evolution of camera becomes more technical and produces exquisite output.

There are lots of cameras sold in the market today and more and more people pay a lot of money to buy an expensive camera to produce quality of pictures. True! Expensive camera produces quality of pictures and most photographers are using it. But for moms who do not need to buy expensive camera, I found out that there are less expensive cameras available in the market which can produce the same quality of pictures of the expensive one.

Here are some of the inexpensive cameras and these cameras has low shutter lag.

  1. Nikon Coolpix L20 10MP Digital Camera. This digital camera has 10 megapixel resolution, 3.6x Optical zoom-nikkor glass lens nikkor optics and can automatically controls shutter speed and ISO settings to compensate for camera shake and subject movement. Now, you can buy this for only $89.00
  2. Canon PowerShot A1100IS 12.1 MP Digital Camera. This digital camera has 12.1 megapixel, with shutter speed ranges from 1/1600 to 15 seconds, has built-in speaker and has SD memory card. You can buy this for only $129.00 with free standard shipping.
  3. Flip UltraHD Camcorder. This camera is one of the easiest-to-use camcorders in the market. It has a feature of 8GB of storage, high-definition video capture, has the ability to use a rechargeable batter pack of off-the-shelf AA batteries and High-Definition Multimedia Interface (HDMI) output.  You can buy this camcorder for only $159.99.
  4. Canon Rebel XS 10.1MP Digital SLR Camera. This DSLR camera is easy to use, has interchangeable lens mount, SD memory card, and 10.5 megapixels. The price is from $669.99 and is now, $449.00 with free standard shipping.
  5. Nikon D300 10.2 MP Digital Single-lens reflex (SLR) Camera.  This Digital SLR camera has shutter that speeds up ranging from 1/8,000 to 30 seconds. You can buy this Digital SLR camera for only $549.95

These are just some of the few inexpensive cameras. When taking a picture, it is important that the camera alone cannot produce you quality and exquisite pictures. You must also explore your own creativity and don’t be afraid in experimenting your own style. Have fun taking pictures!

Understanding the S curve of technology innovation

Though the inception of a new technology seems random, its evolution over time once it comes into existence exhibits a reasonably stable pattern which can best be described in terms of performance characteristic.

The performance characteristic refers to an element of interest to a designer of a product or a user of a specific technology.  For example, fiber optics against the cables in traditional telephone systems provides a better voice clarity. The speed of a computer is another example of performance characteristic that is resulted in new technology. Technological performance can be expressed in terms of any attribute, such as density in the electronics industry (number of transistor per chip) or aircraft speed in miles per hour. The performance of a technology has a recognized pattern over time that, if properly understood, can be of great use in strategic planning. Technology innovation refers to the changes in performance characteristics of a specific technology over time.

The life cycle of innovations can therefore be described using the s-curve which maps again in a different way, ie, growth of revenue or productivity against time. In the early stage of a particular innovation, growth is relatively slow as the new product establishes itself. At some point customers begin to demand and the product growth increases more rapidly. New incremental innovations or changes to the product allow growth to continue. Towards the end of its life cycle, growth slows and may even begin to decline. In the later stages, no amount of new investment in that product will yield a normal rate of return.

The s-curve is derived from half of a normal distribution curve. There is an assumption that new products are likely to have “product life”. i.e. a start-up phase, a rapid increase in revenue and eventual decline. In fact the great majority of innovations never gets off the bottom of the curve, and never produces normal returns.

What is important is that each technology has a number of performance characteristics of a specific technology over time. As mentioned earlier, once a new technology comes into existence, the performance characteristics of interest show very little improvement in the early stages of the technology.

This initial stage is followed by a second phase of very rapid improvement in the performance characteristic. During the third stage, the performance characteristic continues to improve, but the rate of improvement begins to decline. In the final stage, very little improvement is visible and the graph that charts the progress in the performance characteristic of a technology over time takes an S-shape.

The s-curve of technological innovation summarizes four major stages in the evolution of a performance characteristic.

1. Emergence – (also known as embryonic stage) shows little improvement in key performance characteristic. Technology operates far below its potential. Neither the characteristics of technology nor its applicability to market needs may be well understood. A long gestation period exists before attempts are made to produce a technology. This new invention period is characterized by a period of slow initial growth. This is the time when experimentation and initial bugs are worked out of the system.

2. Rapid improvement – improves at an accelerating phase. The technology improvement period is characterized by rapid and sustained growth. As organizations engage in production, experience accumulates over time accelerating the improvement in performance characteristic. The technology becomes vulnerable to substitution or obsolescence when a new or better-performing technology emerges.

3. Declining improvement – it declines improvement.

4. Maturity – further improvement becomes very difficult to achieve. The mature tech period starts when the upper limit of the technology is approached and progress in performance slows down. This is when the tech reaches its natural limits as dictated by factors such as physical limits.

During the early phase, a new technology is introduced into the market place but its adoption is limited to a small group of early adopters and small niche markets. As the product gains ascendancy, new capabilities are introduced and refined with the goal of meeting the needs of the broadest possible segment of mainstream users. During this middle phase a dominant design begins to emerge, winning the allegiance of the market place and also effecting standardization of everything from design to manufacturing. The dominant design in turn allows heightened competition as new entrants realize opportunities for further innovation based on cost, scale and product performance.

This is the period of rapid and greatest growth as a technology matures and reaches the mainstream.  During the final phase the product reaches market saturation.

Some examples of technologies that have followed this path can be stated as follows.

The vacuum tube technology was limited by the tube’s size and the power consumption of the heated filament. Both of these factors were natural barriers to electron conduction in a vacuum tube. Electronic engineers could not overcome these limitations. The arrival of the solid-state tech, or transistor, which permitted electron conduction in solid material, changed the physical barriers of size and power. The transistor tech started a new tech life cycle and rendered the vacuum-tube tech obsolete.

Another example is ceramics, which have higher operating temperatures and substitute for metals used in internal combustion engines; the newer technology permits better performance of the engines. The performance of the engines can continue to improve as a result of a sequence of newer technologies, each with a higher limit of the performance parameter of interest.

What are 1st, 2nd and 3rd Generation Mobile Phones?

Nowadays, everybody has a mobile phone. This article will be looking at the the mobile phone’s history – & its future – in order to discover more about the now-essential telecommunications device.

Mobile phones were born when a number of mobile radio users decided to make mobile phone technology more popular. Mobile telephones were initially installed in vehicles on a permanent basis, but later versions of them, which were named transportables, could also be carried. This meant that they could be used as a mobile or as portable two way radio. During the early 1940s, Motorola developed a two way radio in a rucksack, the walkie-talkie, and this was widely regarded as one of the first mobiles.

First Generation Phones

The very first mobile phones are now referred to as first generation (1G) mobile phones. The first handheld phone to be released on the us market was the Motorola DynaTAC 8000X in 1983. Mobile phones started to gain popularity in the eighties with the introduction of cellphones that were based on cellular networks.

Mobile phones were originally much larger than current ones, & they were initially designed for installation in vehicles only, which is why they were called the car phone. These chunky units were later converted for use as transportable phones the size of a small suitcase & the rest is history.

Second Generation Phones

Second generation, also called 2-G, mobile telephones were introduced in the nineties. 2-G telephone systems were different because of their use of digital circuit switched transmission & the introduction of advanced & quick telephone to network signals. The introduction of 2-G systems saw telephones move from historic 1G telephones to small hand held items, which were much more portable. This change was made possible through improvements in technology such as more advanced batteries & energy efficient electronics.

The second generation mobile telephones had several advantages over 1G items. These included SMS messaging, which initially became possible on GSM networks & eventually on all digital networks. The very first machine-sent message was sent in Great Britain in 1991. The very first person-to-person SMS text message was sent in 1993 in Finland. SMS text messaging soon became the communication method of choice & the general public now prefer sending messages to placing voice calls.

The first pre-commercial 3-G mobile phone network was launched in Japan in May of 2001. 3G was later commercially released in Japan on October, 1 2001.

3-G is the third generation of mobile phone standards & technology, which succeeded 2-G mobile technology. The birth of 3-G technologies enabled network operators including orange to give their users a wider range of advanced services. This includes broadband internet, in addition to high-tech video calls.

Despite the success of 3-G, there has also been many complaints about it. These include criticism over the cost of 3G phones, a lack of network coverage because it’s still a new service & the high power usage of 3G phones.

Ever since the launch of 3G mobile telephone technology, people have been discussing 4-G. 4-G technology will signify the future of mobile telephones, producing the most advanced handsets & best services to date. In actual fact, one of the next services to be developed is thought to be the live streaming of radio and television shows to 3G handsets is & businesses including Disney & Real recently announced that they’ll be offering services like these.

The Evolution Of The Digital Alarm Clock

Remember back in the old days, when you had to get up for school? Maybe your mom woke you up, but maybe you had an alarm clock with a bell on the top that would ring. That clock had a face with three hands: an hour hand, a minute hand, and a hand to show what time the alarm was set for. Bet you miss those days….No? From those days – and even earlier – to the atomic digital wall clocks available now, the digital alarm clock has gone through many changes.

A Bit Of Digital Alarm Clock History

The very first alarm clock was a very personal one. It was invented by a man named Levi Hutchings in 1787, to wake himself up for work at 4 am. It wasn’t until 1847 that someone else was able to patent an adjustable alarm clock. (That was achieved by Antoine Redier, a French inventor.) Both these devices, however, were of the analog variety, as digital alarm clocks were a long time from being invented.

Analog alarm clocks feature the face and hands, and a bell on top, as you probably recall. The time and alarm time were set by turning a knob on the back. Digital clocks didn’t come along until 1956, a relative late-comer to the party.

And digital clocks with alarms came even later. But current digital alarm clocks can do much more than just tell the time and ring the alarm bell! Now, most digital alarm clocks also include a radio, and all offer other styles of alarms, like buzzing, beeping, or even music. The owner can adjust these features, setting the digital alarm clock to awaken him with music or buzzer.

Also, since many of us don’t really want to get up when the alarm goes off, most digital alarm clocks also have a “snooze” button. If the sleeper pushes the button, the alarm will go off and then back on again after a certain amount of time – like 10 minutes. Usually, that button can be pressed over and over as needed – but be careful when using that feature!

Digital alarm clocks will also help one get to sleep now, offering a “sleep” button, so that the music can play for a certain amount of time while the person is falling asleep. Usually, this can be set for up to an hour, but often allows segments of 15 minutes as well. Alarms are getting more useful, being wherever we are – they are now found in computers and cell phones. Who knows what the future holds?

Kitchen Appliances The Evolution

Kitchens have been in existence for many centuries and have always been used for food preparation and storage. The word kitchen derives from the Vulgar Latin cocina and the Late Latin coquina, which literally means to cook. Our modern culture however has evolved the kitchen into a major social and design element of the house, so people can prepare and eat food in style with modern kitchen appliances.

But imagine the kitchen as being a separate room in the house, used only to store food and prepare meals over an open fire using wood or charcoal. Imagine travelling to the nearest well, to fill up your buckets, carrying it all the way back home and waiting hours for it to boil up and cool down safe enough to use. Hard to imagine but this was once the world before kitchen appliances came to existence.

Cookers and Taps – A History

A kitchen appliance was introduced to the Western World between the 18th and 19th century. It was during the industrial period of the 19th century, that architects took to taking the design and function of the kitchen further, by introducing water from taps and cast iron stoves in houses.

Early 18th century industrialisation saw the advancement of technology, which meant that kitchens changed drastically in terms of incorporating new appliances such as the cast iron cooker stove. Earliest models included the Franklin stove, invented by Benjamin Franklin, a furnace stove that was intended for warming up food and not cooking.

But it was not until 1825 that the gas cooker was granted its patent, until this point, all stoves used coal or wood. Early 19th century saw the gas stoves became more popular and commonly used by most households, taking kitchens to the next level.

Not only were gas stoves being installed soon water pipes and sewers were built. Before this collecting water had consisted of a trip to the well, pump or spring every day. It was then carried in a bucket back to the house and heated up for various uses. Certainly, the tap was a major breakthrough in the kitchen design.

Refrigerator Movement

Keeping food preserved and cold was a difficult process before the immersion of refrigerators. Many people would collect ice or snow from the mountains, store them underground which was lined with wood or straw and then filled with ice or snow. This was later known as one of the first cellars in the house.

It was not until mid 19th century after refrigeration was being tried and tested in hospitals to help cool patients body temperature, that James Harrison introduced the first commercial refrigerator to brewery and meatpacking industries. This commercial refrigeration was directed mainly towards brewery’s and almost all breweries used them.

However the natural ice supply became furthermore widespread, allowing it to become affordable and more accessible to the public. This became an important kitchen appliance that evidently evolved in style, size, shape and colour. Appliances at this point became a key element to the design of the kitchen and were ever changing with newer features.

Appliances as a Design

Though these inventions were primarily to make food preparation and storage simpler, efficient and convenient, it was not long before the design element would play an important role. In other words making the kitchen more organised, aesthetically appealing and homely. Catherine Beecher and her sister Harriet Beecher Stowe introduced domestic planning and kitchen layout in 1843.

Their books ‘A Treatise on Domestic Economy’ (1843) and ‘The American Woman’s Home’ (1869) gave birth to the first systematic design using early ergonomics, introducing shelving on the wall, plenty of work space and designated food storage areas.

Post World War II saw women turning to their homes, becoming the key figure of maintaining the home, being mothers and evidently an important consumer to manufacturers. Kitchen appliances were rapidly increasing, introducing standard sized sinks, stoves, worktops and drawers. It very soon included electrical outputs, which were essential for usage of microwaves, blenders, toasters and mixers.

Kitchen appliances have come a long way since the early ages of using wood and coal for cooking food. Nowadays the average homeowner will also benefit from the easy storage of food and enjoy mod cons that aid in reducing cooking time. No longer is the kitchen a separate entity, intended solely for convenient food prep but also a place for entertaining guests, and showing off your modern design that match your swanky appliances.
