Technologies Explained

CMOS

Canon’s CMOS technology is one of the company’s key competitive advantages, with noise reduction circuitry at each pixel site delivering virtually noise-free images. In comparison with CCD technology, the lower power consumption characteristics of Canon’s CMOS sensors also contribute to longer battery life.

Signal conversion in Canon’s CMOS sensors is handled by individual amplifiers at each pixel site. Unnecessary charge transfer operations are avoided, vastly speeding up the process of getting signal to the image processor. Noise generation is reduced, power consumption is limited and faster frame rate potential is increased.

EOS Integrated Cleaning System

The EOS Integrated Cleaning System combats sensor dust in three important ways: Reduce, Repel and Remove.

1. Reduce - Internal camera mechanisms are designed to minimise dust generation. The redesigned body cap prevents dust generation through wear on the cap itself.
2. Repel - Anti-static technologies are applied to the low-pass filter covering the front of the sensor so as not to attract dust.
3. Remove - A Self-Cleaning Sensor Unit uses hi-frequency vibrations to shake dust from the infrared filter for a period of approximately one second after each start up. For instant shooting after power up, this feature is disabled immediately the shutter release is depressed.

Canon has also developed an internal Dust Delete Data system, which can map the position of visible dust on the sensor. This can then be deleted automatically after the shoot with the latest Digital Photo Professional software.

Photography Software : Adobe Photoshop

Review

The software giant Adobe has revamped its popular Creative Suite package and agreed to a new version. Photoshop CS4 provides an improved working space, OpenGL-based features such as rotation of the canvas, new panels for Masks and Adjustments, on-the image that we can apply some adjustments to the style of Photoshop Lightroom, a 3D engine, and then only for begin.

Confines all the characteristic features of Photoshop in a single window of variable size and we can move to any position. If you open more than one document, they are displayed on separate tabs.

With Photoshop CS4 palettes are disappearing. In an effort to reduce the disruption of dialogs, the settings as Levels, Curves, Hue / Saturation, etc., now appear in a single Adjustments panel (settings) which means that your screen is no longer dotted with a few dialog boxes.

Advantages

• Easy to use .
• Good working space.

Disadvantages

• Just the price…

Summary:

I started using PS7 at my work, and I use it mostly for dropping out products ontoa white background for web use. Its a pretty intimidating program at first, and it will take a very long time to master everything it has to off. I have been using the program for about two years now and I have tons of things to learn about the different tools & whatever else the program can do.

Strengths:

Very powerful, easy to adapt to the newest version of PS when it comes out. The RAW converter it comes with does an excellent job. Being able to run batch actions & desiging your own actions is very useful

Weaknesses:

Price. If I wasn’t a student, I wouldn’t have been able to afford it.

Summary:

This is the cream of the crop as far as photo editing software goes IMHO. I have only scratched the surface of what this program is capable of of doing. I was using PS 5 before purchasing this and the new tools like the healing brush, spot healing brush, and patch tools are great for cleaning up old slides.

The exposure adjustment and shadow/highlight tools are also wonderfull additions. These may not be new for people upgrading from CS but are a giant leap when going from PS5 to CS2. For me, the best part about this program is the build in RAW converter. It is so easy to use, and does a wonderful job with my RAW conversions. It’s as easy to use for batching a large group of RAW files as it is a single image.

I also love how the browser opens as a seperate program. The one thing I don’t like about it is that it can really slow down your computer if you don’t have enough memory. I’m only running a Toshiba Satellite P35-S609 laptop with a Pentium 4 3.20Ghz processor (538) with 512mb of RAM right now, and an upgrade would help. This is not CS2’s fault tho.

I gave it a value rating of 5 because I got the student version for $200, There is no dif. between the student version, and the regular version, other than the price. I dought I would have even considered this program if I had to pay full price. UPDATED 2/10/06 per MJS1973 to clarify computer configuration by ken1953

Strengths:

Easy transision from older versions of PS. RAW converter. Browser opens as a seperate program. Very convienent tools such as the healing bursh, spot healing brush and the patch tool.

Weaknesses:

Price, if you have to pay full price that is. System requirements. Beef up your RAM if you don’t have at least 1gig. This program can be very overwhelming if it’s your first time using Photoshop.

Buy Cameras : Digital Cameras Buy Guide

Posted By Agus Mardiana

In this day digital camera prices are cheaper and more affordable. The size, color display and design a wide range. Have all the sophisticated features. The question is, what digital camera you want?

Whether the camera has a cool color, blue or orange for example. Or the camera has a classic look, a special camera? Or even a camera that is thin and comfortable stored in your shirt pocket.

Whatever your needs, there are basically 4 point you should note when choosing a digital camera.

1.      Megapixel

One megapixel means one million pixels. More higher the megapixel, the better the resolution of your camera. Previously, the megapixel feature is a top selling point of digital camera - if not big in megapixel size then the photo will not be good when printed. But now most new cameras have a minimum of 8 megapixel resolution - enough to be able to print a photo in postcard size, large photos or even in size: 16 x 20 inch.

Honestly, the photo generated by the 8 megapixel camera and 10 megapixel camera is very difficult to be distinguished with your bare eyes. If the price is your basic consideration, choose the appropriate and adequate to your budget. Or choose a camera that has better facilities, a longer zoom or a more ergonomic model.

2.      Sensor Size

Did you believe, that you can make the picture better with the 8 megapixel camera than the camera that has a 10 megapixel resolution? How can it be? Of course it can. If only your 8 megapixel camera have a bigger sensor size than the 10 megapixel camera. The larger size of sensor chip, more light that is able to receive (or pixels). The larger sensor size, more data that your camera able to save to produce a good image.

3.      Zoom and Image Stabilization Technology

Currently, almost all digital cameras have a minimum 3x optical zoom features . Some of them even longer. For the standard need, such as birthdays or the holidays, 3x is very good enough. However, if you like taking an object that is located far away from you, such as the object of animals, then choose the camera that has longer optical zoom capability, such as Olympus FE330 features a 5x optical zoom.

New camera models at this time usually comes with the ability of a useful image stabilizer to reduce the effects of shocks and vibrations when you take pictures. This happens if we do photography without using a tripod.

4.      Face Detection Technology

This feature has now been found easily on the latest camera production. This feature allows the camera to recognize human faces, and then set the exposure and focus so that the image quality is obtained naturally and sharp.

Some cameras such as Sony and Samsung can even recognize the smile (smile recognition), but usually this camera has a price that is higher than the other.
