Digital SLR Camera Versus A Compact Digital Camera
Well, it really depends on your budget; however if you do spend the extra money, here's what you get:
In addition to the price falls in the Digital SLR models, the performance on these cameras has increased year on year with the latest Digital SLR cameras being quicker and faster than ever before. They have improved to such an extent that power up or start-up time is near instantaneous with virtually no lag time. “Lag time is the time between you pressing the shutter release button and the camera actually taking the shot”. This delay can vary quite a bit between different camera models and it is one of the biggest drawbacks compared to a compact digital camera. The latest digital SLR cameras have virtually no lag times and react in the same way as conventional film cameras, even in burst mode. Compact digital cameras are catching up; however the difference is still significant. A lag time of ~0.5 seconds can result in you missing the heartbeat of the moment and hence that potential great picture.
Digital SLR camera also has a larger sensor versus a smaller sensor in a compact digital camera. This equates to higher sensitivity and less noise and results in the camera taking clearer pictures in low light. (They also have better autofocus speed in low light as well). A measure of sensitivity in a digital camera is ISO and a typical ISO range for a Digital SLR camera varies from ISO 100 – 1600 with the latter being more sensitive. The ISO range for a compact digital camera varies from ISO 50 – 400. In summary, the higher the ISO rating, the greater the sensitivity and the better the photo can be taken in low light.
The Digital SLR cameras have a much longer battery life due to the limited use of the LCD screen. Please note, that as the LCD screen is only used for viewing the image, the battery life of a digital SLR can allow up to 2000 shots per charge in some cameras compared to 500 for a good point and shoot digital camera.
Digital SLR cameras also allow you to interchange lens such as adding a zoom or macro lens when required.
On the negative side of a Digital SLR camera; they are usually larger and heavier than compact digital cameras, the image cannot be previewed on the LCD screen prior taking the picture. If you really require the image to be viewed on the LCD prior to taking the picture, there are third party manufacturers that produce LCD screens that attaches to the viewfinder and allow the scene to be view just like a compact digital camera. The other drawback is the inability to take videos and finally, lenses are expensive with the majority costing more than the camera itself.
Although compact digital cameras cannot compete on features with a Digital SLR camera, they are great value, have the ability to take videos and are portable. If you have decided to purchase a Digital SLR camera I recommend you visit other websites which has Information on Digital Camera and compare the features. If you are still undecided, purchase both.

Repairing A Digital Camera
To start with you will need a few items of equipment
o digital camera repair warranty covers damage caused by abusing the camera or incorrect use. You also need to check what paperwork you have to send off with your digital camera repair for it to be carried out under warranty, such as the sales receipt and completed warranty card. Your warranty will provide instructions for how to obtain a digital camera repair and the procedures to follow. It is important to use a digital camera repair service authorised by the particular manufacturer of your digital camera to ensure that you do not incur any extra costs. A digital camera repair carried out under warranty will not cost you anything unless the equipment needs to be returned to the factory, in which case there are shipping charges.
One of the most frequent problems that require a camera to be sent to a digital camera repair service is a zoom lens that will not zoom, because the lens is out of alignment. This may have been caused by rough handling or some type of impact which will not be covered by the warranty. If your camera is not able to focus then it will not fire and may print out ‘system error’ or not turn on properly. It is a relatively simple process for a digital camera repair service to realign the zoom lens or reset the zoom barrel guide pins that may have been pushed out of their slots, and this will then enable the lens to focus and zoom. The cost for this form of digital camera repair will vary from service to service but it should be a relatively quick job, as long as the digital camera repair company has the correct equipment onsite. It is worth checking before you decide which digital camera repair service to use that they have the necessary equipment and expertise to carry out the repair and not have to send it away.
The best digital camera repair services have skilled digital camera repair technicians that specialize in repairing certain types and brands of cameras, hundreds of specialized tools to properly service your camera and some may also have custom test jigs to help complete repairs more effectively and efficiently.

A Revolution In Video Production?
To start with you will need a few items of equipment
The Canon XL H1 is long awaited follow up to the industry stalwarts the XL1/2 series. It is the company’s first foray into HDV video and is also the first camera in this range to feature uncompressed HD-SDI output. What this means is that for the first time video producers can purchase a relatively cheap camera (less than US$9000) and edit full uncompressed video, without the disadvantages of using HDV and an intermediate codec to edit.
Whether you are in music video, corporate video, DVD or multimedia production, you now have the opportunity to compete with the larger companies with much higher overheads. This is great for freelancers and the industry in general as productions can be completed at more competitive rates and the huge investment in both camera gear and edit suites doesn’t break the bank like it used to.
Remember the good old days when a BetaSP rig cost you $80-$100000 and about the same for an Avid setup? I for one am sure happy about the reduction in expenses and look forward to seeing some amazing work from everyone with all of this new gear.

Beginners Guide To PC Video Editing
Depending on your requirements or aims there are number of different solutions to discuss, so i will split these up into separate sections.
1.If you are starting from new then i recommend buying a new digital camcorder, this will give you superior video and sound quality as well as making getting started in video editing very simple, so ideal for the beginner. There are thousands to choose from catering for various types of budgets.
2. You may already have an old video deck or camcorder which uses the old analogue outputs such as composite or s-video (be sure to check first what outputs you have). For this kind of setup you would need a capture card/analogue to digital converter, this is discussed in more detail further on in the article.
A PC for Video Editing
It is now possible to easily capture footage from your Digital Camcorder directly to your PC and edit it. If you looking at buying a new PC or building a new one then the currents spec's are more then powerful enough ,a typical spec PC these days is a P4, 512Mb Ram, 80Gb HDD, Windows XP or something along those lines. You could always use your existing PC if you have one, but i wouldn't recommend using anything below a PIII 600.
Additional Hardware
When transferring video from your camcorder to your PC there are a number of additional things to consider depending on the type of camcorder your using. If you’re using a digital camcorder then all your need is a firewire card (also known as an IEE1394 card), a lot of current PC's have these as standard now, otherwise you will need to purchase the card separately. Some of these will come bundled with editing software such as Adobe Premiere but this really depends on which card you buy and how much you spend, once your camcorder is connected to your firewire port windows will automatically recognise your Digital Camcorder. If your using the old analogue camcorder then you will also need an analogue to digital converter, see the section on video editing cards below.
Speed?
Its worth considering your Pc's Processor speed, the speed will effect the rate your video will encode, encoding is where your DV video clips are converted into a more compressed format, for example DVD's are encoded to MPEG2. So the faster the better really. Also consider the amount of RAM in your PC, 256Mb would be the minimum.
Extra Hard Drive Storage
Its worth considering having an extra dedicated drive for your video footage, remember that five minutes of DV footage uses 1GB of hard drive space so consider a large capacity hard drive such as an 80Gb or 120Gb, also consider the disk drive RPM, at least 7200RPM would be recommended. If your PC supports it (most new ones do now), then a Serial ATA (SATA) drive will offer increased date transfer rates of up to 150MB/sec compared to 100 or 133 offered by the IDE drives, you may also consider a SCSI drive if you’re PC has an SCSI adapter as standard.
DVD/CD Burners
If your planning on putting your film onto CD-ROM (VCD), or DVD then a CDRW or DVDRW is an essential piece of kit, most new pc's may have a CDRW or DVDRW as standard, to burn your DVD, you'll need DVD authoring software.
Video Editing Cards
If you have and older analogue video camera/deck then an analogue USB or PCI capture cards will suffice. These dedicated analogue to digital converters take process of conversion away from the CPU and therefore speeds up transfer. If worth getting a quality capture card as the cheaper cards can produce mixed results,
The Video Editing Software
This is where all your creative work starts and the creative work starts, you can capture video from your camera, edit the captured clips, arrange them into a sequence, add transitions, credits and a soundtrack, titles and when your ready export your movie back to the camera or a suitable encoded file format (DVD, VCD etc).

How To Compare Digital Camera Prices
Digital camera prices of $200-$300 are now common for good point-and-shoot digital cameras that come with an image resolution of up to 5 mega pixels and a 3X optical zoom lens. It is important to recognize what the minimum features are to expect for this range of digital camera prices. Digital camera prices between $200 and $300 should include:
* 1.3 frames per second shooting capability
* 10 to 20 scene modes
* built-in flash
* lens openings from f2.8 to f4.8
* optical viewfinder and an LCD of 1.5 to 2 inches
* optical zoom lens with a range equivalent to that of a 35-115mm lens
* rechargeable batteries
* shutter speeds of 4 seconds to 1/2000 second
* solid plastic or metal housing
* video clip capture at 320 by 240 resolution with audio
Digital camera prices can vary and it is essential to know what the most useful features are. Obviously you want to take good pictures but don’t want to pay the inflated digital camera prices that the high-end cameras have. However, your priority should be to assess which features are the most important to enable you to take the best pictures. The higher the numbers of megapixels that the cameras have, the higher the digital camera prices are but this does not necessarily guarantee better pictures.
One of the most useful features to look for in the $200-$300 range of digital camera prices for point-and-shoot picture taking is scene modes. Digital camera prices are not affected very much by having scene modes but these allow an amateur photographer to take shots such as a fireworks display and sunsets without knowing how to adjust the camera settings manually. The majority of the better digital cameras within the $200-$300 range of digital camera prices have scene mode selections available. Another feature of cameras within the $200-$300 range of digital camera prices is that they are compact and will fit in a jacket pocket.

Video Production Equipment: The Director’s Cut
As you prepare to make a video film, it’s a good idea to take stock of your video production equipment required for filming to make sure you have everything that you need. Some common video production products needed for creating a professional looking film include:
* Professional video cameras – From ENG cameras that are slightly larger than your average camcorder to Studio cameras that are connected via cable to dock recorders that do that actual taping, there are many levels of professional grade digital video cameras.
* Stabilization Equipment – Including simple tripods, shoulder mounts, camera dollies and high tech camera cranes, stabilization equipment ensures that the video production is smooth and not shaky. Additionally, stabilization video production equipment can help determine the type of camera shot that is available for a production.
* Film Quality Lighting – Beyond just lights, film quality lighting banks include grip lighting, reflectors, crate grids for lighting effects and scrims to control different aspects of light diffusion.
* Microphone/Audio System – While many video cameras contain a microphone to capture sounds, creating a professional quality video requires separate audio equipment including shotgun mics, audio mixers and pole audio devices.
Editing Video Production Equipment
Once you have your film on video, additional video production gear is required for editing and finalizing a video into a complete entity. Using professional quality editing equipment can give your video the polished quality that separates it from home video or amateur productions. Typical video editing tools include:
* Video Editing Software – Unlike film, which much be edited manually, video can be edited right on your computer. Using professional video editing software, you can add transitions, trim scenes and put the whole project together seamlessly. Selecting the right video production equipment for editing is critical to the final quality of your video.
* Sound Mixing Equipment – A professional video will use sound mixing equipment to balance volume levels, add ambient noise and include a soundtrack to the video. Additionally, sound mixing can transform the standard video mono-audio into a heightened stereo experience.
* Video Duplication Equipment – Once you film is complete, video duplication equipment will be required for copying and distributing your film. Professional video production gear will enable copies that maintain the sound and video quality of your master video.

The Types Of Camcorders
VHS
The VHS format is the oldest type of camcorder. This type of video camcorder is fast becoming outdated, because you can only play back the video on a VHS VCR system. VHS camcorders are not nearly as clear as digital video camcorders that offer clear video with 540 lines of resolution, VHS video cameras only offer 240 lines of resolution. They also weigh more and are much more bulky, that dv camcorders. You can only find these video camera used because their technology is now outdated.
VHS-C
The VHS-C format offer 240 lines of resolution, just like VHS. These analog camcorders come in a smaller size that the VHS camcorder models, but use the same technology. The video tapes used in VHS-C camcorders are much smaller in size than VHS, just in a smaller camcorder design. VHS-C is considered old technology and not used today in newer models.
8mm
If you are looking to record more than 1 hour, then 8mm camcorders are perfect. These video cameras can record up to 5 hours of footage and they offer better video quality that VHS cameras. In order to view video from your 8mm video camcorder, you need to connect the camcorder to input jacks on your TV or your VCR system.
MiniDV
MiniDV, short for mini Digital Video off the clearest and most vivid colors out of all the types of camcorders on the market, and they're small in size only 4 inches in width and height. Mini dv camcorders can fit in the palm of your hand, making them very easy to handle and transport. And if you like editing your video footage you can connect dv camcorders to your computer system. Transferring the video is a snap with the FireWire connection. Once the footage is in your computers hard drive you can burn it to dvd, add it to your web site or email small clips to friends and family.
Digital8
Digital8 camcorders offer the best of both worlds, Hi8 and DV. You can use 8mm and hi8 video tapes combined with the best image quality found in digital camcorder formats. Digital8 camcorders are larger and heavier than Mini DV camcorders, but they are also cheaper in price. The Digital8 system offers 540 lines of crystal clear resolution.
DVD Camcorders
The newest form of digital video cameras are DVD camcorders. These camcorders are small in size, just like Digital8 and Mini DV camcorders. The big difference compared to other camcorder systems is that DVD camcorders use recordable DVD discs such as DVD-R or DVD-RW. The big benefit to dvd video cameras is that they can be played on your home DVD player, and of course the quality is the best you can find.
Price comparisons
If you want to buy the cheapest priced camcorder go for a VHS analog camcorder, you don't get the same quality as digital camcorders however if you plan on filming family vacations this should be sufficient for your needs. Then there are DVD camcorders, they are the most expensive of digital video cameras, but at the same time, they are the newest technology offering the best image and sound quality. Lastly is the mini dv format, this is probably the best camcorder for the price and quality. Small in size and reasonably priced. Review top manufacturers such as Panasonic, Sharp, Canon and Sony which offer the very popular Sony Handycam.

Camcorder - Features To Look For
You should have a general idea of what you need the mini dv camera for. Do you need a video camera for home movies? Or are you looking for a professional video camera, for your next feature film? Think about what you are looking for so your camcorder comparison shopping won't take as long.
Zoom
All digital video cameras have a zoom feature. Older analog camerass only had optical zoom, but new digital video cameras have both optical and digital zoom. There is a difference between these two types of zoom. Optical zoom physically lengthens the lens,and will still give your videos high image quality. However digital zoom basically blows up the scene in a digital format. The problem with digital zoom is that when you zoom in on a subject the video becomes pixilated and blocky with little squares giving the video a blurred and distorted look.
If you're wondering which zoom is better and more important, optical zoom. The more distance that your optical zoom can do, the more flexibility that you have when focusing in on a subject. I suggest a minimum of 10x optical zoom for most consumers.
CCD Sensors and Resolution
The video quality in a dv camera is dependant on the CCD, which is an abbreviation for charged-coupled device. The CCD is an image sensor that converts light into pixels to produce images; your digital camera works in the same way. You can find camcorders with one CCD or three CCDs. One CCD cameras are less costly however you will compromise the color quality in the video. 3 CCD cameras on the other hand provide the best color quality. The reason being is that there are 3 CCDs. Digital video cameras models with three CCDs (one each for red, green and blue) give your video the most vivid colors possible, but the price is more than 1 CCD video cameras.
Viewfinders & LCD Screens
It's important to find the best possible viewfinder when comparing camcorders. The viewfinder is the heart of the camcorder without it you can't see what you are filming. Viewfinders cam in black and white, if you buy a cheap video camera you will be stuck with a black and white screen. Personally I like my color screen, you can see the exact color and video quality as it will appear in the video. Sizes for LCD screen range from 2 to 4 inches across.
Digital Video Editing & Still images
Almost all newer digital video camcorders have FireWire (IEEE 1394). This feature enables you to transfer digital video footage from your camera to your computer system in the fastest possible way. The newest models even have the ability to take digital still images and video and transfer them to your computer for emailing to friends
and family.

Top 10 digital cameras
However, it is not necessary that a top 10 list by a particular site is the top 10 list for you. Since every camera user has his/her own preferences, it is not really correct to assume that one top 10 list works for everyone.
So, the best thing that you can do is to develop a set of top 10 criteria for yourself. Once you do this, then you will be able to develop your own top 10 digital camera list. So, now the question arises that how do you develop your criteria list.
The first and foremost thing to do is to determine the reason why you want to buy a digital camera. What are you going to use the camera for? How do you plan to use the photographs? And the most critical question of all, what is your budget?
Let us assume that you answer the above questions in the following manner :
You want a digital camera to take pictures of your family and during holidays.
You plan to use the photographs by printing them out to put into family albums, calendars and to post them on your web site.
Your budget for the camera is $200-300.
The above statements are enough to narrow down your choices quite a bit.
- You specifically need to look at the battery life of the camera - since on vacation you will not be able to charge your digital camera at all times.
- You also need to see the storage space available on the camera as it will not be possible for you to keep on transferring images at all times.
- You need a camera with zoom options but whether you go for an optical zoom or digital zoom will get decided by your budgetary constraints.
- You need flash since family photographs are normally taken indoors.
- Your camera should be user-friendly, since it is likely that other/younger family members will be using the camera as well.
- The camera should be sturdy as well, especially if you are on vacation with young children.
- The camera should be compact and light-weight as it is not possible to carry big, bulky cameras while traveling.
- A digital camera which can shoot good images to be put on a web site and in calendars needs to have a minimum resolution of 300 dpi. So this is another factor to be considered.
- If you visit the beach while vacationing, then you might want to consider a water-proof camera. However, to fit this into your budget might be a bit difficult. Hence, there are digital cameras which come with water-proof cases and are cheaper. So, this might be the next best option for you.
- You can also go for a digital camera which supports MPG files, so you can click mini-videos. This is a great option for those people who do not possess digital video cameras.

Refurbished digital camera - where and how?
There are a few things that you must keep in mind before you actually choose one.
Before you go shopping for a refurbished digital camera, you must have a basic idea of what you are looking for in terms of features, battery life, your budget etc. The best way to do this would be to determine the uses for which you are planning to buy a camera.
Always remember that there is really no 'guarantee' when you are buying a refurbished camera since it might work well for a few months or it might not work at all. So, it is very important that you check your camera properly before purchasing it.
Also, check the type of warranty that you will get on the digital camera. Is it from the manufacturer or the retailer? For how long is it? What features of the camera does it cover?
One of the most important things is to see whether the camera actually works or not. Even though this might sound a little weird, when you are buying a refurbished camera, it is always better that you properly check each and every thing - since you must remember that what you are purchasing has already been used earlier.
Check whether the proper cables and accessories are given to you at the time of purchase. Mostly, people check only the camera and forget to see whether they are getting the battery charger, USB cable and other devices with the camera as well. If it is your first digital camera and you do not really know what contents you should be getting, then you should ask the seller clearly at the time of enquiry about what will you be getting in the final package.
Nowadays, refurbished cameras can be purchased via the internet as well. But before you choose a particular site/store, try to get a recommendation about the reliability of the site/seller. Ask people who have purchased refurbished digital cameras about their experiences and whom do they recommend.
One of the well known web sites' which sells refurbished digital cameras is Amazon.com. It has a large variety of refurbished cameras and great customer service as well.
