Taking a look apart, it can be observed that quite a few digital cameras use CMOS (meaning complementary metal oxide semiconductor, a technology of manufacturing these microchips) technology based microchips as image sensors. The basic advantage is that CMOS sensors are appreciably cheaper and simpler to fabricate than CCDs. Another great advantage from CMOS sensors is that these take very less power compared to other technology, which adds up to fact as to their extensive use, and can thus even support implementation of additional circuitry on same chip like ADC, some control units etc. Thus it can be stated that CMOS technology based cameras are small, light, cheap and also energy efficient, yet at cost of some amount of image quality.

However common trend remains that all cameras of mega pixel range and higher up use CCD chips instead of CMOS. This is because of fact of picture quality only, leaving aside price differences.

This is basically fact about how digital cameras work! Having known this much difference would not come in photographing expertise of users, but it always feels a kind of satisfaction on understanding inner depths of a device that is so close to eyes!

Making e-books presented a need for a completely different range of knowledge and skills that are built up upon each other. It is not as easy as it looks. For those who do not know much about computers, Internet and web designing, it can be quite a struggle!

For these people, I have got a solution. Perhaps they could use my service to design e-books. I have knowledge and skill that people can use. People can make use of this service at E-book Maker

Think for a while. Almost anybody has something to say that is valuable to another person. Each person has his or hers own experience. A secondary school student may know how to make a cute and adorable doll out of easily obtainable cloth materials. A housewife might want to reveal a special recipe that is handed down from past generations that could become springboard to fame.

A retired carpenter or hobbyist may know how to make a special piece of furniture that will fit some space in living room of an apartment. A car enthusiast may know of some tips about choosing and testing a used car. A sports enthusiast may like to share his secrets of scoring at a certain game. A gambler may have some insider tips that he wants to sell. All these are knowledge that can be tapped and sold.

Talk about Global-Economy! This is it! Anybody is capable of contributing to Global-Economy. If information is useful, and it can be written down, or illustrated, there will surely be someone on Planet Earth who wants to pay to learn from it.

E-books have advantage over books printed on paper. Distribution is instantaneous, cost is low, and format is colorful and interactive, and most important of all, self-publishing for unknown author. You don't even have to find a publisher for your e-book! And you don't have to sell it locally. You can expose it to anywhere on Internet.

Although Internet has leveled playing field somewhat, I found that major players are still dominated by companies in USA. When I scouted around for a reasonably priced facility that will enable me to receive payment for credit card purchases, I could not find many around that will accept participants from my country.

Well, after searching for sometime, I did find one that suits my budget - a reasonably priced one that I can use. You can check it out at 2checkout. Their services are excellent.

Next I went into affiliate marketing. The concept is simple. My website serves as a storefront for other merchant's advertising banners. When people who are attracted by merchant's banners, click on them, they got transported to merchant's website. If visitor buys anything, a percentage of purchase price will be paid to me.

I find that some small money can be made from this. It depends on how well you design your website and how well you encourage your visitors to click on banners. Your website has to be carefully designed and wordings selected to induce people to go to merchant you represent. Some merchants pay 5%, some 10%, and some more. By carefully choosing merchant to match contents of your website you will get more click-throughs. More click-throughs means more sales. It's a numbers game.

Any marketing person will know that more visitors I have, more potential for a sale. So I have to find out how to bring in visitors. The most logical step is to tackle search engines. It is estimated that 80% of all traffic comes from search engines.

This time I explored search engine optimization. How do I place myself near to top of search engine listings? By optimizing for search engines, people will be able to search for my website and it will come out near top and not somewhere in thousandth position. But it's a continuous learning process. Search engines are constantly changing their algorithm to beat spammers. Yes, there are spammers on websites too, webmasters who tries to beat search engine rules.

As my web knowledge improved, I became more and more adventurous. I noticed that many websites have forms that allow visitors to fill up and owner of website will receive information. It's a great way to collect data. So I found out how to do that. It's great fun receiving messages from somebody from other end of world.

Then there are scripts. They can do magic on website. Dates can be automatically displayed and updated. Calculations can be done. Images can be changed automatically. Counters can display number of visitors. Guest books can be signed. They are fantastic pieces of code done by talented programmers.

Since they are so marvelous, I had to make use of them. Some of scripts were described as simple. Indeed most of them are very simple to use. However, when I looked at their source codes, they are extremely gibberish to me. I really marvel at work done by programmers of these scripts. Perhaps in future, I might want to pursue this line of programming activity. I can see great possibilities there.

At this moment, cgi scripts catch my attention. Cgi is short for Common Gateway Interface. They need a bit of tweaking in order to work because they must run on web server on host. Recently I had chance to install a cgi script on a server. It took me a few days of tweaking and communication before it worked, as it should. They are not for faint-hearted beginner. But once beginner has acquired necessary knowledge, these scripts shouldn't be a problem to install. Once they work, you can forget about them, because they will run by themselves, automatically.

Would learner in me be able to teach people? Perhaps it might. After going through many years of hands-on and disciplined study of websites, software, and Internet, maybe I have acquired sufficient knowledge that people might be willing to pay to know. Perhaps this might be subject of another e-book.
