What Megapixel Is Good For Digital Camera

Megapixels - they're not a megaproblem anymore

I've bought a new camera – $10,000-worth.

"Good grief!" gasped my wife. "Are you crazy! How many megapixels exercise you get for $10,000?"

"Er… I'm non sure. X… 12… something like that."

Her jaw dropped. "You lot're not crazy – you're mega-crazy! How can you spend $x,000 on a camera and not know how many mega-pixels it's got!"

Because – low-cal of my life and seat of my desires – "It actually doesn't affair anymore."

What'due south a megapixel?

Digital pictures are made of a grid of coloured dots called pixels. A megapixel is a million pixels – about the same number that makes up the picture on your computer screen. The more finely a picture show is diced into pixels the more megapixels information technology will have, and – all other things being equal – the more particular information technology can show.

Only all other things aren't equal.

Are more megapixels ever amend?

They used to be, simply not at present. Non for near people, anyhow. Back in 1996, the first major newspapers started to go rid of their motion picture cameras for the latest Usa$18,000 "filmless" (digital) ones. These cameras had just 1.three megapixels, and they could be used (at a pinch) to shoot the front end covers for magazines. The quality of these digital cameras really was express by the number of pixels they had. Movie gave better quality. It wasn't until the end of 2003 that National Geographic ran its first full feature shot exclusively with a digital photographic camera - a 5.4 megapixel model.

At present even the cheapest digital cameras have more than enough pixels to make large prints. In that location's even a phone with a 41-megapixel camera. Information technology's other things, non the number of pixels, that decides how good the pictures will await. Expert lenses and good technique are now way more important. More pixels ofttimes just show upwardly these limitations more than conspicuously, and have up more space on your memory cards and computer.

Not all pixels are created equal. Inside the camera, the pixels come from a digital sensor that sits where the movie used to be. The sensor of my $ten,000 camera is 20 times bigger than the sensor in about compact cameras. And then the smaller camera needs 20 times more calorie-free, and a lens 20 times sharper for the picture show to await the same (this is over-simplifying, but bigger sensors really are ameliorate). Without the actress light and a spectacular lens, the pictures on the smaller camera volition exist fuzzier, fifty-fifty if it has the same number of pixels.

This is why digital SLR cameras out-perform compact cameras for shooting indoors, where there is only ane thousandth of the light compared to outside. Take a look at our low-light comparing here. A second-mitt six megapixel digital SLR will consistently out-perform whatever electric current 12 megapixel compact camera indoors – fifty-fifty those costing more. In adept light outside, you lot'd hardly be able to tell any difference betwixt the two – it would come come down to how good their lenses are, and how skilful your technique is.

How many megapixels do I demand?

In my opinion half-dozen megapixels is enough for 98% of uses, and you lot tin can simply make the nearly of that many pixels if y'all have a good lens and use it advisedly. At our photography courses, we pass around an 18"x12" print (45cm 10 30cm) of the picture beneath, made on an old 6 megapixel camera with a good lens.

Anybody agrees that the quality of the impress is fine to put on the wall. If you hold it right up to your nose, y'all can about make out the pixels. Only you can't relish a poster when looking at it from three inches abroad! Bigger pictures are meant to be viewed from further away, so I could blow up this moving picture as big equally I wanted, and it would still look fine at abode on the wall. More megapixels would be a waste for me.

But other types of photography demand as much detail as engineering science can give, and always will. Fine-art and commercial pictures sometimes rely on intricate detail to make the picture work, even when blown up to the size of a billboard. Y'all can't practice that with a meaty digital camera or a digital SLR, no affair how many pixels are crammed into it. Instead, it takes bigger, specialised tools. And for as long equally commercial photographers compete with each other, the development of these tools will never stop. Currently, the cameras for this blazon of work have up to 80 megapixels on a huge sensor, or utilize enormous sheets of motion-picture show that are 5"x4" or even 8"x10". Digital cameras haven't caught upward with film for this market still, and so at that place'due south room for lots more megapixels and even bigger sensors. But the rest of us already have enough megapixels, give thanks you.

What about motion-picture show?

Film has a different "wait" to digital, and reacts differently to light, so information technology's not comparison apples with apples. Digital pictures expect "cleaner" than film, with less speckling, and so digital pictures look improve even when they conduct less detail. But motion-picture show isn't totally dead yet: negative picture (normal film for making prints) tin cope with a broader range of brightness in a single photograph than can well-nigh digital cameras.

But how many "pixels" has film got? I used to scan my slides and negatives at 24 megapixels, until I realised that I was but getting a more than detailed movie of the grain that makes up the motion-picture show. I was using more megapixels than necessary. For practical purposes, I find that half dozen megapixels is virtually the same on negative pic or digital. This is merely a rough number – good quality slide picture is much better than this, inexpensive print film can exist worse – simply it's a starting point.

So why purchase an expensive photographic camera?

Why did I pay $10,000 for a photographic camera? Not for the megapixels. I could have got a stunning camera that takes photos merely as sharp and has more megapixels for one-half that price. I got information technology because it shoots quickly, focuses speedily, it'southward piece of cake to use, and information technology gives excellent quality in low lite, so I don't miss equally many priceless moments. It does very footling that I couldn't practice with a cheap SLR, it just does everything better and faster. When I'1000 shooting unrepeatable events for other people, each photo that I miss while waiting for the camera costs coin.

In Jan 2008, I also bought a v megapixel photographic camera for $100. And I retrieve information technology's got enough megapixels for what I want to do. I've been amazed at the photos it tin can get - here's a gallery of photos I'm taking with it. And it takes videos besides. I don't worry about taking it to the beach. I throw it in the bottom of the pram when nosotros become out with the kids, so it'due south always there. The things that happen in front of its lens are oftentimes more fun and interesting than the things that happen in front of the lens of my expensive camera. And that'due south the key to groovy family pictures that I'll cherish for life.

If you're looking for a new camera, don't get caught up in the megapixel marketing. The days are long gone when it'southward worth paying for extra pixels.

So adjacent time someone asks you how many megapixels your camera has, put on a nonchalent vocalization and but say "Enough".
