Canon's D60 Digital Cameras

!±8± Canon's D60 Digital Cameras

Nick Muskovac, PPSA Palm Harbor, FL wrote very interesting article about Canon`s D60 digital camera. His article is inspired by individual experience and observation.

Author is active user of canon digital cameras. First one he had was Canon D 30. Comparing the canon D30 with D60 Mr. Muskovac finds than, the major difference is that the D60 has much more pixles - 6.3 million pixels which beats the D30 with 3.25 million pixels.

He emphasis that D60 is using the CMOS which draws less power and therefore the camera can shoot more pictures on one battery than most Point-and-Shoot cameras without the loss of image quality.

The major specifications in Mr. Muskovacx` are:

Camera Body

Flash contacts:

(1) Accessory shoe: X-sync contacts

(2) Sync terminal (with locking thread) on lower corner of camera body.

External flash system compatibility: Compatible with E-TTL auto sync.

In my opinion, the D60 camera's most valuable specification and feature is, that it will take all of Canon's EF (auto focus) lenses.

This was a very important consideration for me since I already own Canon EOS equipment and the following EF lenses:

20mm 2.8 28-135 IS 4.5/5.6

100mm 2.8 macro 75-300 IS 5.6

70-200mm2.8 100-400 IS 5.6 300mm 2.8

Putting the camera in action he took few shots and analyzed the quality of the pictures. He used the Canon 100mm 2.8 macro lens. Then he explains "Its focal length is 160 mm when mounted on the D60, an ideal macro lens. I use a twin macro flash, which I have been using for years with my EOS 1N. I shoot in the manual mode with this flash, using the guide number to gauge the distance. The shutter speed of the camera is set to 1/200 sec. I vary the f-stop depending on the distance of the butterfly from the imaginary film plane. The f-stop is generally varied between f16 and f25. When the distance to the subject exceeds 1 1/2 feet, I change the ISO setting from ISO100 to ISO200 instead of opening up the aperture. In this manner I could still use a small aperture value and maintain a good depth of field. With the D60 and 6.3 million pixels, I was able to make a very good 10 X 15 inch print using the largest jpeg image storage mode. Figure 1 shows a Coolie Butterfly taken at ISO200, 1/200 sec, f22, and a distance of about 2 feet".

When he used evaluative metering on the snowy egrets against a green background, the egrets were overexposed. Then he concludes that "the same is true to a lesser extent when using Center Partial Metering and Center Weighted Average. To get the proper exposure on the White Egrets, an exposure compensation of -2/3 to -1 stop was used in the evaluative metering mode. I shoot most all my pictures using the evaluative metering mode".

He pays attention to file numbering systems. We may choose from: (1)Continuous. (2) Auto reset. In the Continuous mode the numbering is continuous between cards. Then he points that Canon software assigns the folder numbers. The image number in each successive folder picks up where the previous folder left off, thereby providing consecutive numbering of images. The time/date is also permanently stored with each image file. Convenient storage functions allows to place Images in folders in groups of 100.

In the Auto reset mode the number resets to 0001 each time you insert a new card.

The D60 image numbering system only goes to 9900. It would have been nice to allow for 100,000 images. Heavy shooters will shoot more than 10,000 images in a year.

Here is an example of how the folder and image numbers work:

Folder Image Range

CANON100 IMG_0001 to IMG_0100

CANON101 IMG_0101 to IMG_0200

CANON102 IMG_0201 to IMG_0300

CANON198 IMG_9801 to IMG_9900

CANON200 IMG_0001 to IMG_0100

CANON201 IMG_0101 to IMG_0200

By keeping images in different folders, duplicate image file names can be identified and then renamed if necessary.

The D60's has nice 1.8 inch TFT color LCD monitor, It allows us to review your images right away.

Important is his comment about the battery life Usualy with 50% flash use and review mode on, he usually can perform between 350 and 400 images on one fully charged battery. He concludes "Reviewing the images does use a significant amount of battery power".

According to the author following features of the D60 that I consider important:

1. D60 can use all Canon EF lenses.

2. Changing ISO settings in mid-roll.

3. Review your picture :immediately after making the exposure.

4. Having a built in 1.6 X extender.

5. Shooting 3 images per second and up to eight continuous images.

He gives the D60 a good grade. Most of all he is impressed with the image quality. According to him "the camera has interchangeable Electronic Focus lens capability, and multiplies your long lenses by a factor of 1.6X. Overall it looks that the D60 is a great camera

Don't Touch That TV Screen - No, Really - I'm Serious - Don't!

!±8± Don't Touch That TV Screen - No, Really - I'm Serious - Don't!

So you just bought a flat screen TV and no one told you anything about care and cleaning?

"What do you mean, care and cleaning?" some will say. "I grew up with a TV in the house, didn't I? Everybody knows how to take care of a TV . . . right? You just dust it off every couple of months and don't let the kids chew on the power cord. . . right?"

Well-l-l-l, there's a little more to it than that when you own a Plasma, DLP or LCD flat screen TV. Some of it is common sense, but a lot what you need to know is unique to caring for the new television technology.

Special care must be taken when handling a flat screen TV, especially when touching or cleaning the display screen. Thin sheets of glass hold the Plasma cells on a flat screen TV, if they crack, the screen is ruined and cannot be repaired!

(If you're not familiar with the differences between Plasma, LCD or DLP TVs, you should Google the "123 Guide To Plasma TV.com")

Bottom line: you need to know what you're doing if you want to protect your expensive new TV from damage. You're in luck . . . I'm about to tell you!

1) Avoid Touching The Screen!

Handle the TV only by the sides and bottom. Do your best not to touch the screen; don't rub, scrub, tap, hit or touch it, since this could scratch, mar or permanently damage the screen. I actually want to encourage you not to touch the screen with your bare hands. (Good luck keeping the kids away from it!)

2) Keep Your Plasma TV Upright!

Whether you're moving it, installing it, storing or displaying it, you should never lay your Plasma flat on it's face, even if the directions tell you to. The plasma elements that make up the picture are sandwiched between two thin layers of glass. If these glass panels crack, your TV screen will be ruined. Large LCD and DLP display screens can be just as delicate.

3) Clean Your Flat Screen TV Correctly!

Even routine cleaning can present special challenges. You shouldn't use dust cloths, chemical cleansers, soaps, sprays, alcohol or aerosols. Please don't rub the screen, just dust it gently with absorbent cotton or chamois only. Clean the frame with a slightly moist sponge or cloth, don't use chemicals or soaps. It's best to unplug the TV before you begin cleaning.

4) Buy A Good Surge Protector!

Spring for a quality surge protector with a reset button and power switch. A phone line or ethernet surge protector for your modem and a coax surge protector for cable TV are great features to look for. If you can't find these features on a power surge protector you can order them separately. A basic surge protector costs less than , and a really good one costs - . There's no excuse for not connecting every major appliance in your house to one. One lightning strike, one power surge and your ,500 flat screen TV could be fried!

5) Don't Let Your Big Screen TV Tip Over!

Most table stands are well designed, but be aware! When your teenager tries to imitate Kobe's fantastic slam dunk or your toddler jumps up to slap Sponge Bob on the head, you don't want a 150-pound big screen TV toppling over on them. Make sure your TV stand is sturdy, that it's large enough to hold your TV (6-inches wider than the base) and is positioned against a wall, away from doorways and foot traffic.

6) Make Sure Your Wall Mount Is Properly Installed!

A correctly installed wall mount has little chance of allowing your TV to tip over; just one more reason to get a professional installation. If Harry Handyman from next door installs your Plasma and the mount comes off the wall, you could be facing substantial damage or injury. If you don't know how to run wiring inside your wall, get a pro to do it.

7) Avoid Screen Burn-In!

Plasma displays have improved recently, but screen burn-in is still possible. Static images that don't move or change, like video game scores, TV station logos, stock ticker displays and computer programs can burn images permanently into a Plasma screen. It may take weeks, months or years for the damage to become permanent, but it certainly can. LCD and DLP TVs cannot suffer burn-in.

With proper care, your big screen TV will give your family decades of brilliant service and lasting memories. Just tune in to Entourage and enjoy!

It's as easy as 1 2 3!

What is the difference between HDMI cables, component cables and RCA cables?

!±8± What is the difference between HDMI cables, component cables and RCA cables?

A look back at changes in technology over the past ten years is difficult to integrate some new technologies with old. Even if a new TV that does not mean that everything that has bought into it, as well as being updated. However, the wires that must go into your components such as HDMI cables, component cables and RCA cables some fixes and updates.

HDMI cables are an improvement of the quality of the transport of audio andvideos. HDMI cables transmit digital images and sound requires the speed of light, do not pass through the video or audio. Because of the way, HDMI cables to maintain the integrity of audio and video, are consistent for connecting DVD players, cable or satellite and music input via a single cable, which is also interchangeable with different types of converters and adapters used. HDMI cables are the best choice for the lead wire configuration to a minimum andthe best from it.

But keep in mind that all the HDMI cable does not mean it will be HD. Thus, the image and the sound of the BlueRay player is not just the same as your 1984 videos from him. The number of HDMI plug-in can be limited on the TV would mean that you can select the devices for the priority.

Component cables are essentially video cables, which are divided into three components. If you are lookingto life, that in 1984 the old movies, as this may be to help to revive these memories again, without having to block and long o. 'Component cable' The name is the fact that the signals are separated to avoid interference with the other derivatives. Most of the components are separated by a video cable and audio broadcasts. The video broadcasts are also other, sometimes separated into color broadcasting, S-Video, RGB and includeYPbPr.

Component cables can run anywhere from a half-foot to 50 feet in length. They are easy to connect, because most TVs have a color matching plug-in at various points on the TV. This means that if you need a rapid deployment of components plug-in cable (such as a camera) are easy to find and offer a quick way to what you want on the big screen.

The most popular type of component cables are RCA cables, which is always composed of a male nameFinish, color and a copper ring around the entrance, which offers flexibility and Stability. Unlike an HDMI cable is the standard for HDMI irrelevant to the quality that comes out. However, the quality of the cables is important. Consider the design of the line and how they are used. If you do not want on such thin RCA cables in the attic, which is upwards of 140 degrees in the summer months, you roll up to 10 meters behind your RCA cables to sendEntertainment center.

When building your home entertainment center, you should be the priority of your audio and video and TV functions, then measure the length, thickness and quality of the cable needs prioritized, and get the most out of your home entertainment center have, as you can imagine.

Long HDMI Cables - Do They Work?

!±8± Long HDMI Cables - Do They Work?

As if that were not enough with all the HDMI "stuff" that the potential buyer to look over a long HDMI cable. In the days of analog video, never the reliability of signal transmission cables long been a problem, but in the early days of HDMI and DVI, we heard the voices of consumers with relatively short run problems, but things have, over time , but the actual length, you can improve the long HDMI cable is not always the driving of a hot potato industry.

We try toCheck out the latest HDMI specification for an answer to the question. Each cable must be tested by the HDMI Authorized Test Center before they are able to obtain certification of compliance. These certificates can be used as a sort of unofficial guide for the length of the cable handy. There are a number of cables that are compatible with lengths over 10 meters and there are some who have passed the exam, are up to 13.0 meters, not shown to deteriorate the signal to a set pointaccreditation bodies. A good tip is to buy certified cable with the latest specification, is at this stage HDMI 1.3b, 1.3 and 1.3a, are also acceptable, but how to pass the test reports of these cables to have to get more restrictive as the standard pre-specific, such as 1.1 or 1.2.

Before you are tempted to buy something more than 13.0 meters (45 feet), are available and marketed as being compatible, then it may be useful to ask to see a copy of, becausethis time the length of 13.0 meters (45 feet) is the longest of any increase in cable (enhanced), I saw that with the proper certification.

That said, there are HDMI cables, which are classified as active, use the power amplifier to amplify the signal allows longer cables are used. An EQ unit is also active on this cable also provides lost data at high frequency and then compare these uses. These systems work, but no reliable informationactual effective length of the additional costs and the additional possibility of failure of delivery of the signal due to the inclusion of additional components may be a step too far for your home entertainment system and is best left to commercial applications.

But all is not lost, if you need to run cable lengths. Just remember, the HDMI specification is so you can be sure that when you generate the signal system compatible (source) can be connected to a compatible device, inthen in turn can be connected to another using the cables are compatible and if you turn everything will work. As with all specifications, there will be some flexibility built in - the drawing - and the input signal is delivered, the HD-enabled equipment is better than it is for these devices to work, seen as necessary. This gives you a range of options, the options that do not fit into are not guaranteed to work like the previous example, but the options that have provenWork and not the additional cost of gain.

There are ports available, while not in accordance with a job to do and, of course, there are long (for compliance) of the cable. If you go this route, it is important to remember that the higher the bit rate of your HD-enabled devices, the less chance of success attracts. We must also remember that this is also for long chains, HDTV, Blu-ray home theater or connected to the Internet Video Streamingrequest to 1080p is to push for longer-range, which has a length commensurate with their limitations. But for 480p, 720p or 1080i, can work well. You can see how this can be lucky.

Now, in light of future developments, that if you put these lines in the walls, etc., as if you were to decide on the limits of this stop you upgrade the cable could take. Take where we are today. 1080p is the new solution for HDTV. Not long ago, 480p was the norm,Then came 720p and 1080i, which uses a bit rate almost three times higher than the 480p standard. Then it was 1080p, the bit rate is doubled the consumption of 1080i and 720p. Now we are on the edge of the media 3D TV, color depth 16-bit and 1460p (and higher), 16-bit color only double the bit rate required for the current standard resolution, so you can see where it could go. Another important aspect in deciding whether or not long. It 'a fact that the cables run out of 2-3 meters(6-10 feet) in length, the issues of lesser quality. A cable leads cost a few dollars and tens of U.S. dollars, but when you enter the kingdom is not of quality match is worth much more. In general, the lower the quality of the cable is less then the actual distance of work is increased if the image resolution or color depth.

So, to reveal what was said about long HDMI cables and their reliability. For lengths, the HDMI-compatible,the length of over 13 meters (45 feet), their use is more or less guaranteed, even if they are less expensive options for 480p, 720p, 1080i and - though not always reliable - 1080p so go ahead and use them contrast with confidence. The same goes for the shorter cable from 1-3 meters (30-10 feet) in length, although caution should be exercised when using them in long signal chains, as might be unreliable. Cheaper ways of longer HDMI cable work on the limits of itperformance capabilities may struggle in the 1460p, 16 bit color future and their use needs to be questioned if their installation is behind ceilings or walls as the additional cost of a more expensive cable may be less than a complete re-install in the (not to distant) future. The use of over compliant length HDMI cables needs to be linked to all the factors mentioned above but with the rider that the best method of testing if it will be successful still lies with plugging it in. Even at these lengths, the cheaper options are still worth considering if the installation of long HDMI cables is easily accessed and they work OK with your present equipment.
