We have seen different kinds of digital cameras on the wholesale digital camera. According to the common uses, the digital camera can be simply divided into DSLR camera, card camera, long lens camera, home camera and paraxial camera. The DSLR camera is the digital single lens reflex camera. There is no clear concept for the card camera. It’s usually the kind of camera which is small in shape, light in weight and fashionable in design. The long lens camera refers to the large optical zoom model. The larger the optical zoom rate is, the longer the distance can be.

Image resolution rate
The image resolution is the optional imaging size and the basic unit is the pixel. The smaller the pixel is, the smaller the image coverage. In practice, the large pixel can be used for the high quality and large coverage output. The length and width ratio is 4:3.

Exposure
The exposure modes are usually divided into shutter priority, aperture priority, manual exposure and AE lock. The photo quality is related with the exposure value. And the exposure value is relative to the light time (decided by the shutter speed) and light coverage (decided by the aperture size).

The shutter and aperture priority
In order to get the right exposure volume, you need to make the right combination of the shutter and aperture. Large aperture is for the faster shutter. The larger the aperture is, the more light rays are. The shutter priority means to gain the F-number through the metering in the condition of manual user-selected shutter. The shutter priority is mostly used in the shooting of moving objects, especially in the sports shooting.

The unclear photo of moving object is mainly caused by the slow speed shutter. You can estimate the shutter value according to the specific object. 1/125 second is ok for shooting the walking people. The dropping drops require 1/1000 second.

Manual exposure mode
The aperture and shutter speed is left to the manual operation in the manual exposure mode each time. It’s convenient for the photographer to make different photo effect. If you want to take photos with the motion trace, you can longer the exposure time, faster the shutter and increase the exposure. If you want the dim effect, you should faster the shutter and decrease the exposure. Thought it is very initiative, it’s not convenient. And the time doesn’t permit you to catch the vanishing prospect.

AE mode
AE is Auto Exposure. There are modes of aperture priority AE, shutter speed priority AE, program AE, flashlight AE and depth-first AE. The aperture size is user selected and the shutter time is automatically selected according to the brightness of object and CCD ISO in the manual aperture and automatic shutter time mode. It’s suitable for the shooting of landscape, portrait and macro photography.

Multi spot metering
It’s a mode to reach the best shooting effect through the brightness from the different direction of the object and flash compensation. First, the user should meter the source object and make the AE lock. Second, do the metering of the backlight object. Most of the professional or semi-professional camera will do the analysis automatically.

The HiPhone 3GS is the third generation of iphone designed and and marketed by Apple Inc. Its features primarily consist of faster performance, a camera with higher resolution and video capability, voice control and support for 7.2 Mbps HSDPA downloading (but remains limited to 384 kbps uploading as Apple had not implemented the USPA protocol). It was released in the U.S., Canada and six European countries on June 19, 2009, in Australia and Japan on June 26, and internationally in July and August 2009. The iPhone 3GS runs Apple’s iOS operating system, the same operating system as used on previous Iphones.
In the days leading up to Apple’s announcement of the iPhone 3GS, the advancement of Hiphone 3G Phone, we published a report card that would measure the actual device’s features against 20 different things that users were hoping that a new iPhone would contain. Following the announcement, we wanted to go back and take a look at how the iPhone 3GS actually compares with these potential features; here are the answers.
1. Dramatically Better Battery Life. No. By Apple’s measures, the iPhone 3GS which is HIphone Dual SIM received no improvement in 3G talk time, and only modest boosts in other performance categories. Users should expect an extra two or so hours of use of non-phone features, but the same rapid power drain when making 3G telephone calls. Again, switching the phone from 3G to EDGE mode is recommended – ridiculously – as a means to improve run time.
2. Superior Build Quality. Unclear. The screen is touted as possessing a “fingerprint-resistant oleophobic coating,” also described as “oil-resistant coating that keeps the iPhone screen clean.” It is uncertain whether this coating has been applied to the rest of the device’s body, and whether the plastic shell has been improved to reduce cracking.
3. More Reliable Calling and Data Speeds. No. While the iPhone 3GS supports 7.2Mb/s HSDPA data transmission, Apple made no promises about the actual availability of cellular service for this faster speed, and suggested that AT&T would be offering it “where available.” Given AT&T’s current coverage maps, it is unclear where it is available, and data speeds will most likely be unpredictable for months to come, or longer. One bright spot is that a faster processor in the iPhone 3GS will enable Safari and other applications to open up faster.
4. No Bandwidth Capping. Yes. AT&T has not changed its 3G pricing plans for the worse in terms of bandwidth capping. But it has also not offered iPhone 3GS pricing details for the use of two new announced features, MMS and Internet Tethering, both of which will consume additional data.
5. 802.11n. No. The iPhone 3GS still works only on 802.11b and 802.11g wireless routers, slowing down 802.11n-capable networks as a consequence.
6. Turn-by-Turn Mapping. No. Despite the presence of Google Maps, a GPS chip, and now a digital compass in the iPhone 3GS, Apple is still passing the buck to third-party developers to actually create software for turn-by-turn directions. Moreover, it is actively promoting Tom Tom, which will offer a windshield-mounting hardware and new app software package for mapping for an undisclosed additional fee over the cost of the iPhone hardware.
7. No More Broken Accessories. Unclear. The iPhone 3GS does not appear to break compatibility with prior accessories to any greater degree than did the iPhone 3G, however, testing will be necessary to see how both past and new iPhone OS 3.0-ready accessories behave when connected to the device. Two accessory failures during the WWDC 2009 demonstration of the iPhone OS 3.0 software may or may not be related to the iPhone 3GS device itself, which was reportedly being used during the product demos. 8. Integrated or Accessory Keyboard Support. No; the iPhone 3GS does not include an integrated keyboard and, thus far, Apple has announced no support for keyboard accessories. However, developers may be capable of creating their own, standardless keyboards; it is unclear whether these accessories will work.
9. Joypad Support. No; neither a joypad nor support for joypad accessories has been announced for iPhone 3GS. However, developers may be capable of creating their own, standardless controllers to work with specific games; it is unclear whether such controllers will create a mess of incompatible solutions. 10. An Improved Main iPhone Menu. No. Users still need to scroll through pages of icons.
11. An Improved Splash Screen. No. The main screen remains uncustomizable.
12. Improved Still Camera Performance. Yes. The iPhone 3GS received several camera-related upgrades, including a 3-Megapixel still camera capable of autofocus, manual focus, 10cm macro photography, and other features: rapid-shooting, auto white balance, and supposedly better low-light performance.
13. Video Recording. Yes. The iPhone 3GS can now create 640×480, 30fps videos with audio, and edit them directly from within the phone, sending them to MobileMe, YouTube, E-mail, or MMS (where supported). Videos published to YouTube are capped at 10 minutes in length; Apple also says that “the limit to the file size of attachments is determined by your carrier.”
14. Video Conferencing. No. The iPhone 3GS has no front-facing video camera and is not capable of sending video across a Wi-Fi or cellular network in real time, at least directly out of the box.
15. Direct-to-iPhone Video Downloading. Yes. The iPhone 3GS, as well as older iPhones, have gained the ability to download standard-definition movies, TV shows, and music videos directly over the air.
16. Wireless Syncing. No. A wired connection is still required to transfer iPhone content to a Mac or PC, and vice-versa.
17. A Higher-Resolution Screen. No. The iPhone 3GS screen has not improved in resolution over its 2007 and 2008 predecessors.
18. HD Content Support. No. The iPhone 3GS is listed as supporting 640×480 videos in the same formats as its predecessors, and is not capable out of the box of playing higher-resolution videos.
19. More Storage Capacity. Yes. The iPhone 3GS saw its storage capacities doubled from the iPhone 3G, with a 16GB base version and a 32GB premium version.
20. True Multitasking. No. Apple has announced no support for this feature, and will rely upon Push notifications as an alternative.
For those keeping count, only 5 of the 20 aforementioned features actually appeared in the iPhone 3GS—a 25% figure that isn’t necessarily meaningful given the universe of possible additions, but does suggest the iterative nature of the actual iPhone 3GS product. A list of additional features Apple did add, including Voice Control, Nike+ support, and enhanced accessibility features, is available on Topons.

Helpful Tips in Making a Wedding Video

The wedding of your sister is coming up and due to a tight budget you were tasked to take charge of the wedding videography. Having the basic knowledge in digital videos and owning a camera does not actually qualify you to do the best job. It may seem like a demanding task but you decide to take the challenge head on. It can be a nerve-wracking experience but being prepared can do wonders for you. Here are some useful tips that will surely help you improve your digital videotaping skills in a matter of days:

• Use manual focus instead of automatic

Although all cameras have automatic focus, it is recommended that you use manual focus if possible. It is for the reason that you will have to switch constantly from one a plane to another.

Using auto focus can be a great help most of the time but unfortunately it is not perfect. In situations like macro photography, low lighting conditions, portrait shots, shooting through glass and action photography, the manual mode is much better used.

• Use both hands in handling the camera

To accomplish having a steadier image it is important to remember to hold the camera with both hands. This simple tip is usually overlooked by beginners.

• Plan your video shots

Plan ahead of time all the events of the wedding so you will have a clear idea what you can shoot on your own or if you need more assistance. You need to be able to manage your time very well because you can never recapture something that has already happened. You should also have a video timeline. This means in your wedding footage you should all have the elements that are needed to complete the entire wedding video. These include an introduction, getting ready shots, the ceremony, and reception.

• Interview the couple

A good addition to the wedding video footage is to interview the couple separately. Oftentimes this part is undervalued. Do the interview before the ceremony starts while they are getting ready.

• Shoot extra footage

One common mistake of all videographers is not having enough material for the wedding video or they took only one shot of a moment that could have been extraordinary. Avoid this by taking as many shots as possible.

• Your movements should be smooth

You should keep your movements smooth and calculated so that the images will register unto the screen the same way.

• Match camera settings

To prevent color mismatch, make sure the white balance settings are identical. Exposure manuals should be set in maximum control.

These tips are only a few things you can develop to be prepared in shooting the much awaited wedding videography. Remember these helpful guidelines are just the basics for a beginner like you. It is still important to have lots of practice and to gain lots of experience if you ever do decide to pursue the world of videography.
