What are the two main file formats for saving digital pictures in a digital camera?

JPG and a native (proprietary) RAW format. TIF used to be common, but no more. JPG is a "lossy" compressed format, limited to 8 bits of information per RGB chanel, per pixel. The term "lossy" means that the data isn't completely (1-for-1) restored when it's saved. RAW formats vary, and are highly dependent on the sensor in the camera. Instead of using the firmware in the camera to render the image, you use software in your computer to render the image. The file typically caries 10 bits of information per RGB channel per pixel, or more. This can give you more options for dynamic range (ratio of lightest part of the photo to the darkest), and finer graduation between the colors.

∙ 8y agoMost digital cameras record in the JPEG format, a standardized compressed format that is in broad use across operating systems and manufacturers. Because it is compressed, it allows more and larger images to be stored in the memory. Most cameras allow you to select the level of compression you want, trading space on the memory chip for detail in the image -- lower compression level, more detail.
More expensive cameras record in both JPEG and RAW. RAW is uncompressed, unaltered storage of data from the camera's image processor. It allows almost unlimited manipulation of images in post processing, because everything that the camera captures is saved intact.
There are two disadvantages to RAW files. Most obvious is that they are HUGE compared to JPEG, several times as large. That, and the fact that most amateur photographers would never use them, is why they are not made available in consumer grade cameras. Another is that since different camera processors produce slightly different data, not all RAW files are the same. Fortunately, the best examples of post processing software are set up to accommodate RAW files from all the major processor manufacturers, so this is not an issue in the vast majority of cases.

What is the difference between a video camera and a digital still camera?
Conventional/traditional photography is the use of film to capture images in a camera. The film then must be developed, resulting in negatives (negative images) of the images. These negatives are then enlarged using special equipment and paper and then printed and developed chemicals. Digital cameras capture images using sensors on a memory card, which are then transferred to a computer for printing on specialized printers. The benefits of traditional darkroom photography is the amazing quality of the photographs. Only in recent years has digital photography even began to compare to the quality of traditional film, but it is increasing in both quality and popularity. In the near future it is projected to be equal to and even surpass traditional photography. The benefits of digital photography are the ease of use and convenience. Images can be viewed and deleted instantly, instead of shooting through multiple rolls without knowing if you have a successful image.
What are the Disadvantages of camera phones?
The main advantage to a camera phone is most people always have their phones with them and can instantly upload the pictures. The disadvantages are running out of space and the quality is not professional.
Why was the digital camera created?
Originally the camera was made to capture a moment in time quickly and exactly. Paintings often reflected the opinion of the painter in their art, however, photos show exactly what was happening. Photos can be biased but nonetheless they are real. Photography started becoming pretty well known around the civil war and that's where the first "imbedded" journalists began.The first use of a lens that projected light onto a wall was the camera obscura (dark chamber)- this is where the name 'camera' comes from. The concept of 'light paintings' was created long before a method of permanently recording the image. The merging of physics and chemistry was required to allow this and resulted in the discovery of silver elements that turned black when exposed to light.The main reason for its invention was to help artists in drawing difficult subjects. However, since the physics behind the camera were discovered by many different people across the world, they were subsequently used for different reasons.

What is the advantage of digital cameras over film cameras?
These days everyone seems to have a digital camera. Is it really better than film? Digital cameras have many benefits over film:No expensive film to buy and develop.Preview your pictures instantly; delete at your leisure.Upload pictures quickly to your computer for viewing.Manipulate and fix pictures using photo manipulation software installed on your computer. No need to visit a photo lab or consult a professional.Higher resolution on some cameras, which allows for higher quality images.Ability to print pictures from your computer. No need to visit a lab for printing or development.Yeah, and nobody gets to see the sleezy pictures you take with your girlfriend!Devils Advocate...No expensive film to buy and develop. -> Replace that with very expensive inks, expensive paper, photo inkjet, software, batteries and spare batteries, and a camera that costs 2 to 3 times as much as a comparable film camera, and one that will be obsolete within a year. Film "expensive"? Prices have dropped substantially to a couple bucks, or less, a roll for 35mm.Preview your pictures instantly; delete at your leisure. -> Yes, advantage digital. However, you don't get a negative. Ever have a hard-drive crash, or a CDR become unreadable? It's not a matter of "if" it's a matter of when. Make sure you make multiple back-ups of your memories (and don't lose them, and label your CDRs...) Otherwise, rots-a-ruk. See those three years and hundreds/thousands of photos. Wave bye-byes.Upload pictures quickly to your computer for viewing. -> You can scan film with a cheap scanner or get a photo CD from a lab and do the same thing.Manipulate and fix pictures using photo manipulation software installed on your computer. No need to visit a photo lab or consult a professional. - "Consult a professional"? Huh? If you don't own a printer, or computer, or don't want to spend hours learning digital editing software you will still be making trips to the photo lab to make your digital prints. And isn't it nice to just drop off your film, wait a couple days, and have everything ready, already printed without sitting in from of a PC, fooling with software, or wrestling with a printer, and watching your expensive ink get used up?Higher resolution on some cameras, - That's just flat out false. A 35mm camera has the equivalent resolution of a 20 megapixel digital camera. The "some" cameras you must be talking about are digital 20 megapixel medium format "backs" used by pros that cost $10,000. Most consumer digital cameras - even DSLRs, have 3,4,5,6 megapixels. Less than half the resolution. That's why ONLY film can be used for big enlargements.- which allows for higher quality images. Sometimes yes, sometimes no. All digitals have great difficulty with bright conditions and have a much lower latitude than film. It is very easy to over-expose, and you will get washed out or "blown out" highlights. They also have a lower dynamic range, and - excluding expensive DSLRs, have a wide depth of field - everything in sharp focus. Not something you /always/ want, expecially with portraits. With the digicams most consumers use, you're limited to iso 200 speed, othewise you get unacceptable digital noise (far more distracting than grain) but I /always/ use 400 speed film and not think about it.Ability to print pictures from your computer. No need to visit a lab for printing or development.- Again, that's not all it's cracked up to be. Inkjet printers are notoriously finiky. Hard drives containing /all/ your pictures may crash. Photo-editing software can cost hundreds of dollars, ink prices are outrageous, and photos use /a lot/ of ink. Good injet paper is also pricey.I started using a digital camera, used it for a year, went back to film... Film is also more fun imo, and my film SLR is 15 years old. No need to charge batteries or carry spares, or for it to "boot up". It's ready to go as soon as I pick it up.Will you still have that expensive digital camera in 15 years? Our will you have purchased 2,3,4 in that amout of time?Digital is good for pros who shoot thousands of pics a week, where film costs DO become an issue. It's also good for camera companies, since like computers used to be, they're obsolete the minute you buy them.Besides, film is just more fun...How digital is better? It is worse in every aspect! 1. First of all film is much more fun. 2. Quality of 35mm film is better than some $10.000 digital. 3. Film is MUCH CHEAPER to shoot and to develop: SnapFish.com develop whole role for $3. The whole role of slide film to developed and mounted $4 with Fuji mailer.. 4. Film lasts for as long as we need and digital requires backup and how doing you know it will be readable in let say 10 years? Can you read the 8 inch diskettes now? 5. Film make you better photographer and offers HUGE variety of different films to try and to experiment: any ISO is available. 6. Film is getting better every year, but not your digital camera sensor is growing. 7. With 35mm I have a REAL WIDE ANGLE shots. 8. I don't have to keep half of pocket of batteries with me. 9. The camera from some $150 will do better than digital of $2000. 10. I can have the real high quality slide show, not that crappy and dull multimedia projection. 11. After all I can have my slides and negatives be scanned and have a "digital" if you whish. 12. I have the whole bunch of photos after vacation developed by the same SnapFish, scanned and put on CD for less than half of your ink jet paper cost.AND AGAIN FILM IS FUN, ENDLESS FUN. Photography it is about imagination it is not what you can see in the LCD.Agree with everything in the last two posts. Film is just more fun, and it's less expensive. I like to experiment with different lenses and different types of films. The $100 SLR I bought a decade ago, still going strong. Tried digital, it's "okay"... imo, more hype than anything. Okay if you want to post pics on a web. Get a cheap one.Disadvantages of digital point and shoot:1. Limited to 200 iso. 400 iso downright ugly due to noise. Grain is not as obtrusive.2. Wide angle lenses! Love'em. Forget it with digital. 35mm best you can do without expensive, ridiculous teleconverters and "the widest" you'll get is 24mm, with a huge, heavy WCON on Raynox teleconverter hanging off your camera. I can get a 19mm, 20mm, 21mm fixed wide angles that are small.3. Price/Quality. The average price for these things is $400 to $500 for a camera that is obsolete at purchase, with a fixed lens.4. EVF or LCD screen... bleh. Hard to see, wash out in bright light, go dark in not so low light. Keep'em.Why spend this kind of dough, for a fixed lens camera that limits you to iso 200, when you can get a good new SLR with a prime lens for $150, that simply takes better pics.If you want a digital, get a cheap $100 Kodak for quick snaps to post on the web. Don't worry about megapixels. Even the cheapest has suffient for okay snap-shots.DSLRs Good cameras, can't argue with that. But a DSLR kit will set you back $800 min. for just a body. Lenses are outrageous. Figure on parting with $1500 min for a body and a couple lenses.- Battery eaters - "Start-up" time - Dirt on CCD nightmare - VERY expensive - Just not as much fun - Blown out highlights - Moire patterns - Durability - Fragile --- extreme temp damage --- moisture (don't get caught in the rain or humid contitions) --- static electricity --- overall build qualityDigitals require expensive software, printers, inks, and papers to make prints, and good luck with that storage media. Years from now, will it work when you want it to? Will it still be used? Can you find it?Digitals produce "high resolution digital images". They don't look like film. That's why films are still shot with film on film cameras, even though it's less expensive to shoot on digital and transfer to film. Even TV dramas are still shot on film.The only thing the "so called" digital revolution did was sold a lot of crappy overpriced cameras to people. Due to planned obsolence, people are buying expensive new cameras with more megapixels every couple years. Whereas, a film camera will last decades. The only people who benefited from the "digital revolution" were consumer electronics companies and commercial photographers, who spend tens of thousands of dollars on film and processing a month. For the average shooter or hobbiest, the -'s of digital outweigh the plusses.Digital. This is progress? No thanks, I'll stick with film.9-07-2006I'll use digital from now on probably. If only for one's personal use and looking at, why take all the time? If you have time, and someone is buying your work, or you are having it shown in a gallery, film is nice. I have been using digital now for several months, and now I have grown so old that I now get a kick out of just looking at the 2.5 inch LCD on the back of my camera!! Film or Digital, I LOVE PHOTOGRAPHY!One thing I didn't see mentioned is that film will degrade over time, unless kept in pristine conditions. Digital media will not. You can reprint your pictures with the same quality as the first time. Try that with film. Now given, if you are the photographic equivalent of an audiophile, go with the film by all means. But if you are just a novice photographer like myself who might like 10 of the 96 pictures you snapped, go with the digital.A novice photographer doesn't have the experience or authority to judge this. I hope you have your files backed up.My grandmother can use a digital camera, but that doesn't make her a photographer. Digital cameras make for lazy photographers. You don't have to take the time to get the lighting or the shot exactly right because you can just take it to Photoshop later and alter it.They aren't.They are different and neither one is better than the other.Digital makes for lazy photographers is BS. Lazy photographers make for lazy photographers. On a good dSLR you can have complete manual control, but most professional (make their living with it) photographers stick with Aperture priority (Av) or Shutter Priority (TV) .. this is the same from 30 years ago: look at the auto film cameras fom 70's on, they were set like this. No pro I've ever met use 'auto' for most of their pictures, they knew what settings worked for the environment and used them. Auto (your complaint) is meant for grandma, not artist Suzie or photo-journalist Bob.Any work done by pros on photographs (NOT images) is meant only to correct what they camera can't show, not to produce new graphics. If you can't take the picture in-camera, you're not a photographer.The newer dSLRs are as good or better in a lot of cases than a 35mm SLR: 5-18MP, ISO that's good to 800, even 1000 with light grain, batteries that last 1500 to 2000 images, and better capture software arrives ever day.Film is good for enlarging: 10MP or more 3/4 sensor sized images are a minimum for poster sized enlargements, 20MP and full size sensors are needed for 4 foot and bigger prints. How many people do that?I still take pictures with film. In fact I prefer film over digital but the wait for results is less important with my landscapes than my people pictures, so I often use digital. My camera bag has 2 Nikon dSLRS, a point and shoot Canon (goes everywhere the Nikons can't go), 2 auto 35mms (Canon and Nikon), 2 manual 35mms (Canon and Nikon): The autos are for sharing with others, the digitals are for when I'm taking lots of pictures or I have a real weird environment, but for permanent and professional looks it's the manual 35s. The lenses are better, the consistency is better and they work in any condition (blazing hot, freezing cold, wet, snow, hail, dirty or... well whatever!)Want to learn how to make photographs? Get an old 35mm film camera and practice, practice, practice. Photoshop can't fix bad photography; if you didn't catch the subject in focus and focus was on another subject, nothing in PS can fix that. That's why some people still make 100's of thousands of dollars as photographers; they can do what photoshop can't.There are so many things involved here. The main question asked by the respondents should be: what are you using the camera for?If you want pics to look at on your computer monitor (eBay, kijiji, pics for facebook) use any digital camera, a monitor only resolves at around 75 dpi anyway.If you want to produce art and print it on paper at poster size or greater use film, especially if you want it in black and white.I have been doing this for over 30 years and I use both digital and film, it depends upon the requirements of the job.Decide what you want to use the camera for and buy accordingly.- - - - -I always love the "higher resolution" comment about digital cameras. Let's play.A popular digital camera has 12 megapixels. (There are a bunch of these out there.) That will give you a file approximately 4000 pixels wide x 3000 pixels high.If you take your pictures to a photofinisher to have them printed, their machine runs at 300 dpi...so for the highest quality out of this file, the biggest picture you can print is 10 x 13.Now, a 10 x 13 is a nice size picture, but you look over there and see "Poster Size Prints Available Here" on a sign. And they have 24 x 36 prints available. You will need a file that's 7200 x 10800 pixels, or 74 megapixels, if you want to print that at 300 dpi. An $18,000 Better Light back for your view camera can do that, but most people would rather spend $18,000 on a new car than on a part for a camera. (You have to supply a view camera separately and they are expensive.) On the other hand, you can buy a $350 Plustek film scanner and crank out files this big from 35mm negs all day long.And this is the most important thing to realize about digital camera files: they can never get any larger without damaging them. If you take a picture on a 12 megapixel camera, and a year later buy an 18 megapixel or a 22 megapixel camera, all the work you shot on your 12 megapixel camera will remain 12 megapixels. If you enlarge them in Photoshop, they get ugly quick. If I scan a negative this week and need it larger next week, I just need to put it back in a scanner and make it larger.

What are the differences between digital and filmed camera?
A film camera records a photo onto a strip of film, which then needs to be taken to a photo clinic to be processed. The quality is about 25 megapixels. A digital camera records a photo onto a memory card, which can be reviewed on the camera's screen instantly, and you have the option of deleting or saving it. The quality can range from 8-12 megapixels, which is considerably lower than a film camera.
How do scanners and digital cameras operate?

Digital Cameras Make Picture Taking Easy?
Not long ago, picture taking was a tedious process. You had to take the pictures, rewind the film, take it to the store, pay for developing and then wait for your pictures. It was also an expensive process. But with a digital camera, picture taking is, literally, a snap. Owning one can make keeping track of life's adventures so much easier.No More Wasted FilmWhen you had to purchase film, you also had to worry about wasting pictures. Letting the kids take a picture was out of the question. But with a digital camera, if you make a mistake, you can simply delete it and try again. You will recoup the purchase price of the camera easily by saving on film development. Not to mention, you have your pictures instantly - no more waiting for your pictures to come in to the store.Unlimited PicturesToday's digital cameras are also made to use a storage card. You can get cards that hold several gigabytes of pictures. This allows for nearly unlimited picture taking. If your card fills up, just remove it and add another. Or better yet, download your pictures to your computer, erase the card and start filling it up all over again.Get Ready to PrintYou can print your digital pictures directly from your computer. They even make printers specifically for that purpose. You can also take your storage cards or CD to retail stores and have them printed there. Another fantastic advantage of digital pictures is the ability to make scrapbook pages on the computer and print them. You can crop images, add other images or apply other special effects.Very AffordableDigital cameras have come a long way in the past few years. They are not only a great thing to have, but have become affordable. You can purchase a nice, easy to use camera for under $100.00, which is perfect for just about anyone's budget. Purchasers can buy extra lenses and other equipment to take your photography up to a professional level. The quality of pictures taken and the compact size of digital cameras makes them one of the best tools a family can own.
