You have a great digital single lens reflex (dSLR) camera and want to capture some wonderful pictures of the times of your life. To fully master your dSLR and. makers – as new cameras and software arrives on the market – has made gov/iad//docs/Public%20SP%%20November%pdf. Cameras are complicated. I was frustrated with my first DSLR. I just couldn't capture what I saw through my viewfinder. It took a ton of trial and error. When I.
Exposure compensation can be used on some automated modes and semi-automated modes like aperture priority. File Format The file format is how your camera lens will record the image or image file. Raw files contain more information than JPGs, which makes them more suitable for photo editing in various editing software. It informs the angle of view how much of what is being shot will be captured and the magnification how large things will appear. Different focus areas determine if the camera is focusing on multiple points or one user-selected point.
Flash Sync You probably know that the flash is a burst of light—flash sync determines when the flash fires. Normally, the flash fires at the beginning of the photo, but changing the flash sync mode adjusts when that happens. The rear curtain flash sync mode, for example, fires the flash at the end of the photo instead of the beginning.
An ISO means the camera is very sensitive to light, so you can use that higher ISO for getting shots in low light.
ISO is balanced with aperture and shutter speed to get a proper exposure. This technique is useful for shooting still objects in low light used often by landscape photographers , or rendering moving objects into an artistic blur. Metering is actually based on a middle gray, so having lighter or darker objects in the image can throw the metering off a little bit. Metering modes indicate how the meter is reading the light.
Matrix metering means the camera is reading the light from the entire scene. Now that you have the photography terms mastered, learn the fundamentals of photography with John Greengo. Learn more.
Noise Noise is simply little flecks in an image, also sometimes called grain. Shutter Speed The shutter speed is the part of the camera that opens and closes to let light in and take a picture.
The longer the shutter stays open, the more light that is let in. The sensor measures the color and brightness of each pixel and stores it as a number. Your digital photograph is effectively an enormously long string of numbers describing the exact details of each pixel it contains.
You can read more about how an image sensor produces a digital picture in our article on webcams.
25 Common Photography Terms All Beginners Need to Know
How digital cameras use digital technology Once a picture is stored in numeric form, you can do all kinds of things with it. Plug your digital camera into your computer, and you can download the images you've taken and load them into programs like PhotoShop to edit them or jazz them up.
Or you can upload them onto websites, email them to friends, and so on. This is possible because your photographs are stored in digital format and all kinds of other digital gadgets—everything from MP3-playing iPods to cellphones and computers to photo printers—use digital technology too.
Digital is a kind of language that all electronic gadgets "speak" today. Photo: Digital cameras are much more convenient than film cameras. You can instantly see how the picture will look from the LCD screen on the back.
If your picture doesn't turn out okay, you can simply delete it and try again.

You can't do that with a film camera. Digital cameras mean photographers can be more creative and experimental. If you open up a digital photograph in a paint image editing program, you can change it in all kinds of ways.
A program like this works by adjusting the numbers that represent each pixel of the image. So, if you click on a control that makes the image 20 percent brighter, the program goes through all the numbers for each pixel in turn and increases them by 20 percent.
If you mirror an image flip it horizontally , the program reverses the sequence of the numbers it stores so they run in the opposite direction. What you see on the screen is the image changing as you edit or manipulate it. But what you don't see is the paint program changing all the numbers in the background.
Some of these image-editing techniques are built into more sophisticated digital cameras. You might have a camera that has an optical zoom and a digital zoom. An optical zoom means that the lens moves in and out to make the incoming image bigger or smaller when it hits the CCD.
A digital zoom means that the microchip inside the camera blows up the incoming image without actually moving the lens. So, just like moving closer to a TV set, the image degrades in quality.
In short, optical zooms make images bigger and just as clear, but digital zooms make images bigger and more blurred. Look out of a window and try to figure out how you would store details of the view you can see.
Step 3: Pick a decent subject with good light
First, you'd have to divide the image into a grid of squares. So you'd need to draw an imaginary grid on top of the window. Next, you'd have to measure the color and brightness of each pixel in the grid. Finally, you'd have to write all these measurements down as numbers.
If you measured the color and brightness for six million pixels and wrote both down both things as numbers, you'd end up with a string of millions of numbers—just to store one photograph! This is why high-quality digital images often make enormous files on your computer.
Each one can be several megabytes millions of characters in size. To get around this, digital cameras, computers, and other digital gadgets use a technique called compression. Compression is a mathematical trick that involves squeezing digital photos so they can be stored with fewer numbers and less memory.
JPG is known as a "lossy" compression because, when photographs are squeezed this way, some information is lost and can never be restored. High-resolution JPGs use lots of memory space and look very clear; low resolution JPGs use much less space and look more blurred.
You can find out more about compression in our article on MP3 players. Most digital cameras have settings that let you take pictures at higher or lower resolutions. If you select high-resolution, the camera can store fewer images on its memory card —but they are much better quality. Opt for low-resolution and you will get more images, but the quality won't be as good.
Low-resolution images are stored with greater compression. Turning ordinary photos into digital photos There is a way to turn photos from an ordinary film camera into digital photos—by scanning them. A scanner is a piece of computer equipment that looks like a small photocopier but works like a digital camera. When you put your photos in a scanner, a light scans across them, turning them into strings of pixels and thus into digital images you can see on your computer. Inside a digital camera Ever wondered what's inside a digital camera?
What takes the photo? Where's it stored? What makes the flash work? And how do all these bits connect together? When you take electronic gadgets apart, they're much harder to understand than ordinary machines things that work through a clear physical mechanism : you can't always see which part does which job or how.
Even so, it can be quite illuminating to peer into your favorite gadgets to see what's hiding inside. I don't recommend you try this at home: opening things up is the quickest way to invalidate your warranty; it's also a good way to ensure they'll never work again!
The main parts of a digital camera Photo: The parts in a basic digital camera. Were it not for the LCD screen and batteries the two biggest components , you could probably make a camera like this as small as a postage stamp!
I've opened up the camera in our top photo—and these are the parts I've found inside: Battery compartment: This camera takes two 1. Flash capacitor: The capacitor charges up for several seconds to store enough energy to fire the flash. Flash lamp: Operated by the capacitor.
It takes a fair bit of energy to fire a xenon flash like this, which is why a lot of indoor flash photography quickly uses up your batteries. LED: A small red LED light-emitting diode indicates when the self-timer is operating, so you can take photos of yourself more easily.
Lens: The lens catches light from the object you're photographing and focuses it on the CCD.
Focusing mechanism: This camera has a simple switch-operated focus that toggles the lens between two positions for taking either close-ups or distant shots. You can't actually see the chip in this photo, because it's directly underneath the lens.
But you can see what it looks like in our article on webcams. To your computer, your camera looks like just another memory device like a hard drive. SD secure digital card slot: You can slide a flash memory card in here for storing more photos. The camera has a very small internal memory that will store photos too.
Processor chip: The camera's main digital "brain". This controls all the camera's functions. It's an example of an integrated circuit. Wrist connector: The strap that keeps the camera securely tied to your wrist attaches here. Top case: Simply screws on top of the bottom case shown here.
Another important part, not shown here, is the LCD display that shows you the photos you've taken. It's mounted on the back of the electronic circuit board so you can't see it in this photo. How do digital cameras compare with smartphone cameras?
From what I've said so far, you can see that digital cameras are great things—if you're comparing them to old-style film cameras, that is. Thanks to their superb, cutting-edge image sensors, there's really no good reason other than a nostalgic preference for analog technology to use film. You might be forgiven for thinking sales of digital cameras would be rocketing as a result, but you'd be wrong.
Over the last few years, digital cameras have seen double-digit falls in sales in parallel with the massive rise of smartphones and tablets which now sell more than a 1.
Check out a photo-sharing site like Flickr and you'll find the most popular "cameras" are actually phones: in June , at the time I'm writing this, Flickr's top five cameras are all iPhones. Is there a good reason to own a standalone digital camera anymore or can you now do everything with a camera phone?
Photo: The pros and cons of digital cameras and smartphones summarized in three photos. Even point-and-shoot digital cameras like my old Canon Ixus have bigger, better, telescopic lenses top and sensors compared to the ones in the best smartphone cameras, like my new LG middle.
But smartphones undoubtedly score on connectivity and they have bigger, better, and clearer screens bottom. Here you can see my smartphone's huge screen pictured in a preview photo on the Canon's tiny screen.
Sensors and screens Step back a decade and there was no comparison at all between the rough and clunky snapshot cameras on cellphones and even the most mediocre compact digital cameras. While the digitals were boasting ever-increasing numbers of megapixels, cellphones took crude snaps little better than the ones you could get from a basic webcam 1 megapixel or less was common. Now all that's changed.
My new LG smartphone comes in at 13 megapixels, which theoretically, at least sounds like it must be twice as good. But wait!You can read more about how an image sensor produces a digital picture in our article on webcams.
If you are just reading it in your office, or a restaurant, or a coffee shop, then no matter what, you will never learn it.
Imagine that you are looking through a small round hole in a fence. When you half-press the shutter, focus will be acquired and locked on to a given subject.
The Ultimate Guide to Learning how to use Your first DSLR
The more sensitive the sensor becomes, the more image noise it creates. The lion is in focus, the bear behind is out of focus. Practically Speaking: A lens that encompasses a range of focal lengths is a zoom lens. I am now probably risking to get a negative evaluation of my physics knowledge, which would unfortunately be quite fair The ISO sensitivity control is usually useful with insufficient light.
