Digital Cameras

It is hard to quantify which digital camera bundle is the best because there are different categories of digital cameras. In terms of price, the most economical is the Samsung WB 150 bundle, which can be had for under $175.

The aperture ring changes the lens aperture which controls how much light reaches the film or digital sensor.

A large aperture f/1.4 to f/2.8 = lots of light, fast shutter speeds, narrow depth of field

A small aperture f/9+ = much less light, slower shutter speeds, wide depth of field

Kinda depends, generally in my experience the size of a jpeg high res image directly from, say a canon t2i, is between 5.5 and 11mb, some as much as 16mb. An estimate therefore would be approximately 2979, 1489, and 1024 pics respectively. This however is only an estimate as each picture has different information which takes up more or less space than the previous picture even on the same device. Aditionally, it's unlikely that you would be using or keeping pictures in raw, but if you are, expect considerably less than that, on average canon raw files are around twice the size and generally save jpeg as well for menu images. So it would put that average number at around 750 or so pics, but most likely less.

You can find a waterproof Fuji camera at many online retailers including Amazon, Fuji Film web store, and Ebay. You could also walk into stores such as Target, Best Buy, or Kmart and purchase this camera.

All of the major companies are good choices. Pentax, Nikon, Minolta, Olympus and Canon are all top level manufacturers. Some of the less expensive brands such as HP, GE, Polaroid and similar economy brands are rebranded merchandise from the same manufacturers. They give good service, but not generally on a level with the major brands.

Choose any of the above names with confidence, then decide what you can afford to pay and shop for features.

Digital ID, also known as a digital certificate, is a form of electronic credentials for the Internet. Digital certificate is issued by a trusted third party to establish the identity of the ID holder. The third party who issues certificates is known as a Certification Authority (CA). Digital certificate technology is based on the theory of public key cryptography. In public key cryptography systems, every entity has two complementary keys, a public key and private key, which function only when they are placed together. The purpose of a Digital ID is to reliably link a public/private key pair with its owner. When a CA issues Digital IDs, it verifies that the owner is not claiming a false identity.

Try by removing the memory stick and then attaching the camera to computer with USB cable. Switch on camera. It should open up a dialogue box in Windows XP (or similar OS). Select 'open folder to view file' or open Windows Explorer and open camera folder (probably displayed as new drive E: or like that in My Computer) . You may also check whether there is an option of selecting "camera as mass storage device" in settings menu of camera. If yes then select this before connecting. If you have no means of attaching the camera to the computer, place an empty memory stick into the camera. In review mode, a message indicates there is no data, but there is in the internal memory. While still in review mode, press the menu button and go the the "Setup" section, the last option. Now, scroll down to the "Memory Stick Tool" section. From there, highlight the "Copy" choice at the bottom, and select the OK option to proceed. You will get a message: "All data in internal memory will be copied." Press OK, and it will copy everything in the internal memory to your memory stick. Then, when you have plugged the memory stick into your computer, you will find a new folder entitled Copy. All your photos from the internal memory of the camera will be in there.

Pixel is a contraction of "picture element"; the term is applied to a wide range of technologies - for example, digital cameras usually use a charge coupled device (CCD) sensor where photons of light affects the amount of charge on each pixel of the sensor. However, the image is copied to buffer memory in the camera - where each pixel is actually a few bytes of RAM, finally it's copied the solid state memory where, again, each pixel is a few bytes - but of solid state memory.

For display technologies, pixels might start on a computer hard drive, move to the computer memory, then to the display memory before describing elements on the LCD screen..

Sony is a very good company which sells good memory cards. They come in 8 Giga Bytes, 16 Giga Bytes and 32 Giga Bytes. They also come in a larger capacity but they are not popular. Best Buy and Walmart carry Sony digital camera memory cards.

kilo means 1000, mega means a million, so a mega-something contains a thousand kilo-something.

A digital certificate confirms the information has come from the source it's claimed to be, and that the site is encrypted for transactions to be exchanged.

i have the nikon D3100 and i love it there are so many options etc

there are several answers i could come up with for this one, depending on the OS you use, many systems use empty hard disk space and convert that into what is called "virtual memory." so systems use both, actual memory installed, and virtual "paged" memory. so to simplify the answer, the more memory you have, the less time programs have to use your hard disk "memory" to finish, or run tasks. when your drive is being accessed for memory, it takes away access time for applications. The limiting reagent model: your system can only go as fast the the slowest reagent. Information moving from memory to CPU - fastest, speed of current Information moving from Hard drive to CPU - slowest, friction of drive turning to access information More memory means more information can be stored electronically and be accessible electronically. Of course, all of this must take into account your OS and how the program you want to run is coded. If the program will not load into memory but constantly accesses the hard drive by design, more memory will not help it so much. More memory really comes into play with the processes behind the scenes in Windows. By having more space for Windows XP to run free, you allow necessary functions to flow quickly.

The aperture is like the iris of the eye. When the aperture is very small, you will get a sharper focus and more depth of field-- near and far things in the scene will tend to be sharper. This is because the smaller circle is cutting down on the "confusion" caused by the countless overlapping circles of light being focused on the film or other light sensitive surface in the camera. The down side is that because the iris is smaller, less light is getting in, and you need a longer exposure to get a good image. When the aperture is larger, you can get a good image with a faster exposure, but sharpness and depth of field may suffer a little. The "circles of confusion" are larger, because the aperture is larger.

A single lens reflex (SLR) is a camera that uses the same set of lenses to both focus the image on the CCD (digital) and enable the photographer to frame the picture. That is to say, when you look through the viewfinder of a DSLR you are looking directly at the object through the main lens. You are not looking at the digitally re-created picture of the object or through some other lens that is off-center of the main lens.

A point-and-shoot camera will have some other mechanism for framing the picture.

An image is made up of pixels, or tiny squares that each have a designated color. the pixels are normally so small that you don't see them. However, sometimes a picture looks blurry when resized. That blurry image is a pixelated image.

The cheapest digital picture frames are usually the smallest. They're cheap because it doesn't use up a lot of pixels to make your image, or not nearly as much as a bigger picture.

It is measured in a fraction of a second. For example 1/500th of a second

It all depends on what type, make and recording medium your camera uses.

If it is tape and has an analogue output (AV leads) then you will need a computer with a video capture device added.

The card or dongle will have appropiate connections on it, for the AV leads. The devices also come bundled with the software to do it and instructions.

Some digtial cameras use a 'firewire' connection. But again your computer will have to be equipped with the correct socket. If it isn't already, then it can be added.

If you camera uses digital media, such as disc or memory card, then insert the media in the correct slot on your computer. Open the files and copy and paste them onto your hard drive.

If you're talking about optical zoom there is no difference other than you will be closer to the viewed object.
If you are talking about digital zoom, the size of the pixels will increase and blur.
Hope that helps!

the chargable cell different from ordinary dry cell like.Like chargeable cell can be charged ;And ordinary dry cell cannot be charged .

is it NTFS or PAL format sony dsc 30 Camera the pal version does not have English settings

if its a ntfs version just take the batery out or freeze it to restore factory settings
