I think the PSP camera is only sold in Japan and the US. I was told this by someone at a GameStop.
GAME in the UK sometimes has them.
What is the light sensitive part in the camera?
With film cameras the film captures the image. With digital cameras an electronic device with many small sensors (the number of sensors determines the megapixel count) captures the image and sends it to a computer which records it on a memory card.
How do you charge a digital camera with usb cord?
Depends on if the camera is built to allow that or not.
If it is, just plug it in. If it isn't, it won't work.
Disposable cameras start with the entire roll of film wound up OUTSITE the spool/canister.
As you take pics, and wind the film, the negatives are moved into the canister, so, when you have taken all the pics, and fully wound the film on, it can then be safely removed from the camera. No point, really, bacause you will be unable to reset a fresh roll into that camera...
How do you get a clean picture on a digital camera?
My guess is you're asking about motion blur. Try these effects, depending on the speed of subject motion and the effect you desire.
1) use a slow enough shutter speed to induce motion blur. You may need a tripod to steady the camera if it gets to be too slow to hand hold. Subject in motion will blur to some degree.
2) Using an example of a fast moving car: Pre-focus on the spot where you want the subject to be when you take the shot. You will have to consult your camera manual on how to do this if it is an autofocus model. Begin following the moving subject, keeping it in the viewfinder. Just as it approaches the predetermined spot, take the picture, and follow through a bit (don't stop following the subject when you press the shutter release). The car will be relatively sharp while the background will become a blur.
Where were most western films made?
Many films were shot on the backlots of Hollywood studios. Some were shot on location. Director John Ford shot many of his westerns in Monument Valley. It's in Utah and Arizona.
Can you make spy camera at home?
You can get a digital camera or a video camera or whatever and put it somewhere obvious but not to obvious, then you put like a jacket or something over it, but make sure you can still see the lens. If you are going out put a jacket over it, make sure there are other clothes around it, so it looks you have got dirty laundry or something.
How do you unlock a samsung digital camera's memory card?
You may find a small slider on the side edge of the card to lock and unlock it. The idea of it is to prevent accidental erasure of images.
How do you ask a girl to pose for photograph?
Just be casual about it.
If this is for a photography assignment,and your maybe asking her to pose nude or just normally,explain to her the situation,maybe why you'd like her in the photos ect (so she doesn't think your being a perv) and just see what she says!
If worst comes to worst she could just say no thanks and then you can find someone better to work with.
Hope it helped :)
Having a drink first helps. The above response is right, be casual. If you're taking a college course and have access to a studio you should have no problem, I never have. Explain your involvement with photography and explain that you need a model and that there is no payment for it. It also helps if you can provide her with a small portfolio of pictures after the session. Good Luck.
What do you call a picture that was taken with an infrared camera?
It is called a Thermogram, or a Thermal Image
In photography what does contrast mean?
Contrasting Images in poetry is when the writer portrays one image or scene then portrays a different image/scene. This poem written by Matsuo Basho is an example of contrasting images, "An old silent pond... A frog jumps into the pond, splash! Silence again."
Megapixels are just one measure of a camera's quality. The quality of the lenses is just as, if not more important, in terms of picture quality. And, pixels vary a lot in quality--some are smaller than others, and result in worse picture quality.
You can find 5 megapixel cameras for $90, and others for several hundred dollars. The difference in price is due to better mechanics and better optics. A tiny plastic lens, no matter how many pixels the sensor has, will give you crappy photos. A good lens, on the other hand, can give you clear crisp photos with 2 or 3 megapixels.
And too many megapixels is not necessarily a good thing--more megapixels mean larger file sizes, which will fill up your hard drive (if you store them on your computer) quickly. 5 megapixels will give you files which will let you print 8x10 photos without a problem.
Other things which will determine how clear your photos are include:
- Proper lighting
- Lens quality
- Steadiness of camera
- Proper focus
- Proper shutter speed
- Clean sensor/lens
If you are concerned about photo quality, read some reviews of the camera you are interested in on-line, or go to a camera shop (and not an appliance store that sells camera) and talk to the staff and try out the camera.

Is digital photography considered digital art?
Yes it can. Architecture as a form of art dates far back in time to the temples of the Greeks, pyramids of Egypt and the stepped pyramids in South America. Many of the new buildings being designed and built are very much art. Think of the Bird's Nest Stadium built in Chin for the Olympics.
Which companies make pink digital cameras?
The major camera manufacturers include (in alphabetical order):
- Canon
- Casio
- Fujifilm
- Kodak
- Leica
- Nikon
- Olympus
- Panasonic
- Pentax
- Ricoh
- Samsung
- Sony
However, they do not manufacture all their digital cameras. Often, they will put their label on a digital camera that another camera manufacturer, e.g. Sanyo, has made.
Why are silver compounds used in photography?
Silver is used in film media because it tarnishes better than other materials.
Tarnish is the process of oxidation, where a metal turns from some some shiny color to a darker non-shiny color.
Three Examples of Tarnish:
- Gold: Starts a bright shiny gold color and tarnishes to a slightly darker dull gold color
- Copper: Starts a bright shiny orange-gold color and tarnishes to a green patina color
- Silver: Starts a bright almost white color and tarnishes to a very dark grey, almost black color
Silver provides the best tonal range, from light to dark. It can capture light from pure white to pure black (or very close).
Additionally, silver tarnishes very consistently. This provides a smooth transition from light to dark on film.
Where can you print poster sized images of celebrities?
You can get printed poster sized of celebrities at Sam'sor Cotsco's but believe me they cost alot of money at Cotsco's so get your own huge printer where they cost less at Wal-Mart.:)
How was the movie camera invented?
the camera was developed by Joseph Nicéphore Niépce in 1826. to capture instant moments in time.
How good is 10.2 megapixels for a camera?
All other things being equal, you will not notice a difference except for the larger file sizes for the same size of picture taken. If you aren't using the camera professionally, I suggest you concentrate more on features. These days, people seem more interested in big numbers (for pixel size) because it's the easiest thing to discuss around the water cooler. IMHO, anything over 6 MP is a waste unless you're getting a bargain.
How does a hologram differ from a photograph?
A photograph is a two dimensional representation of a real-life scene. A hologram is three a dimensional representation.
What is an aperture of a camera?
Original answer moved to discussion page.
The aperture is an opening within the lens whose size is controlled by a series of overlapping blades. It's sole purpose is to control the amount of light that reaches the film or digital sensor during the exposure time. Anything else, such as depth of field, is a spin off of its function.
The size of this opening is controlled by settings on the camera shutter speed/aperture dial or on the lens. Many cameras do not have the ability to "stop down" the aperture before the moment of exposure, so it is not something most people can observe. At the moment of exposure, the blades move to create an opening within the lens just before the shutter opens to control the duration that this occurs. Together, they control the exposure.
We quantify the size of this opening with F numbers. Simply put, the F number expresses how many times an aperture will fit into the focal length. Thus, in a 100mm lens, F4 means it will fit in 4x and will be 25mm in diameter. In a 200mm lens, F4 represents an opening of 50mm. This explains why longer length lenses typically have larger maximum apertures, and why the higher F number represents a smaller aperture (F16 must fit into the focal length 16x, thus it has to be smaller).
The answer moved to the discussion page, while good, was more about the effect of the aperture and really belongs in a answer to a question about depth of field.
How do you change the dpi of a photograph?
I can only partially answer this, because in my view there are several factors.
1: In the camera you can set the resolution of the photo when it is taken. Stretching that photo to fit a certain print size will then result in a certain DPI. 2: You can resize a photo in an editor. But use caution, as there are different resize methods. Some result in better quality than others. It is possible to end with an image which says it has a high DPI value, but the content is actually low in pixels. So you have wasted file space and you still end up with larger pixels than necessary. And last, you can keep the file large and wait to scale it until you are ready to mail or print. At that time you should be able to select the dimensions in inches or cm.
I rarely pay attention to the actual DPI value becaue the result can be unpredictable and dissappointing. Instead, I prefer to stick with pixel dimensions and let the DPI adapt as it may.
Are you are trying to change to a smaller or larger format? What are you starting with and is it the screen size or printing size you are concerned about?

Do slr lenses fit all cameras?
Generally, no. Each manufacturer has proprietary mounts for their lenses and, for example, Nikon lenses will not fit a Canon and so on. There are aftermarket lenses made to fit various cameras, but you need to specify the make and even sometimes the model of the camera in order to get a mount that fits.
How can we increase nokia5200vga camera to megapixels?
You can't. The no of pixels a camera has is determined at its manufacture. To get more pixels you'd have to replace the actual plate at the bottom of the camera that catches the incoming light. And that's not doable outside a very specialized workshop.
What is the difference between digital camera and webcam?
A digital camera is a portable camera that runs on batteries and usually has a slot for a memory card to save pictures and videos to. They generally have better image quality, presently ranging from around 8-12 megapixels on average. This is what you usually see people carrying around for taking pictures. A webcam is a small camera that connects to a computer [or is built into a laptop] and is generally used for video chats online. They have lower quality than a digital camera.
Adventage of candid photography over protraiture photography?
There are no real advantages to either style..it is a matter of personal taste. Some people have a preference to more formal portraits when the need is for business use. Candid photography is more suited to events with families and friends.
