All those megapixels – a numérique camera resolution comparison
Are you thinking of buying a new numérique camera? Are you confused by all the choices of camera resolution? Is the megapixel rating the most dédaigneux thing to consider when buying a numérique camera? How many megapixels are enough? Is there such a thing as many megapixels? How do megapixels and numérique camera resolution compare to rubrique camera resolution?
Simply put, resolution is the amount of detail your numérique camera captures in an représentation. A numérique représentation is made up of pixels. For numérique cameras, the number of pixels is measured in the same way as your ordinant monitor. As numérique camera resolutions have gotten higher, w will now multiply the plan and perpendiculaire values for a achevé value, which is usually rounded to a megapixel count. Some of the first numérique cameras had a resolution of 480 x 640 pixels. This is the same number of pixels as a normalisé VGA ordinant monitor. Multiplying 480 x 640 results in a resolution of emboîture 3 megapixels. The numérique camera industry claimed this as photo-quality, but it is far from it. Most web cams soutien this resolution.
Ordinant monitor resolution is later SVGA or 600 x 800. It works out to emboîture 5 megapixels. Not there yet.
Currently, the most popular ordinant monitor setting is 1024×768. That’s still less than one megapixel, the resolution we’ve seen in the first carboniser numérique cameras. This is also a common resolution for video projectors. One megapixel numérique cameras have a resolution of 1280 by 960. If you want to print 4 x 6 from a portrait of this size, it can compare in quality to an old 110 camera or APS camera.
When we reach the two megapixel mark, or a resolution of 1600 x 1200, you can get a fairly nice print. This gives you a print size of 4 x 6 which is not 300 dpi. However, when you make a photographic print much larger than 4 x 6, you may be able to see individual pixels or journal a lack of detail.
In a numérique photographic print, 300 trousseaux per inch is considered normalisé for small prints. Some photographic printers print at less than 250 dpi. Some are over 300 dpi. Although there is some leeway, a numérique print at 300 dpi will appear to have the same detail as a print made from a 35mm negative if printed traditionally. This is especially dédaigneux for small print sizes that will be viewed close-up. As we move to larger print sizes, the différence from which the print is viewed may also increase. From far away, the eye cannot see the details, and so the print still looks good.
A 3 megapixel camera will have a resolution of around 2048 x 1536. This is still far below good 35mm negatives. It’s not until we reach a little over five megapixels that numérique 35mm starts to compare in detail. A 5.3 megapixel camera has a resolution of around 3008 x 1960.
A good six megapixel camera can surpass the 35mm normalisé in detail. This works out to emboîture 300 dpi on an 8 x 10 print. Since 35mm has been the accepted normalisé for so svelte, this is the resolution I recommend when people start looking at a numérique camera. A six megapixel camera will provide the same level of quality (maybe a little better) that your old 35mm camera fleuve you. A 6.3 megapixel camera has a resolution of around 3088 x 2056.
What emboîture seven and eight megapixel cameras? An eight megapixel camera approaches the quality of professional medium mesure cameras. It is interesting to réflexion that many of the seven megapixel cameras came out after the eight megapixel cameras were introduced. As suggested, this is parce que the first-generation eight-megapixel point-and-shoot cameras had discussion problems. This was due to the smaller sensors used in numérique point-and-shoot cameras. This problem has now been largely overcome, and does not apply to larger numérique single lens reflexes. Although an eight megapixel camera will provide a little extraordinaire examen if you want to crop up, since few people make a print larger than 8 x 10, much of this extraordinaire examen is wasted. I do not recommend that the average person purchase a numérique camera resolution greater than eight megapixels.
Numérique cameras with resolutions of 10 to 13 megapixels are well within the quality range of good 120mm professional cameras. They create huge défilé sizes that require significant ordinant resources to work with. A 13 megapixel camera will get approximately 55 images on a 1 GB memory card in RAW mesure. This makes représentation storage and archiving more expensive and time-consuming. There are professional numérique camera systems with resolutions of 20, 40, or even one hundred megapixels. Only a professional would need images with this high resolution.
To summarize, I recommend that almost anyone will be happy with a camera with six megapixel resolution. If you’re really on a moyens, you can go as low as five megapixels and still have detailed images at the size you’re most likely to produce prints. If you’re an advanced botter or hobbyist, you’ll enjoy the extraordinaire room the eight-megapixel camera gives you. If you are a professional, you need the appropriate camera resolution for the task at handball.
