What parameters of the matrix of a digital camera should be for good pictures of the format A3 ???

- The theory of this case is: from what distance will this A3 be considered? If from 40-50 centimeters, then the number of pixels along the longest line - the diagonal should be at least 2000. If closer, then, appropriately, more. When viewing a photo 10x15 with 25-30 centimeters 1500 points - this is the norm, when the eye ceases to see points, and perceives them as a line. 2000 on the diagonal is 1600x1200 points = 1,9 Mpx. But this is the theoretical minimum. Almost from the 4-hmegapixel matrix, you can already squeeze the 30x40 format and this will be 100 dpi (linear pixels per inch). It is almost better to have the order of 150 dpi. This increase will cause the matrix volume to grow by 2,25 times. The matrix in 9 Mpx is quite sufficient for printing high-quality posters 30x40,

The physical size of the matrix affects the overall quality of the photograph. Small mattresses make more noise when shooting in the regime time (after sunset) when shooting without flashes. All this is due to the fact that each pixel has very small dimensions and a high level of so-called. noise - dirty ugly colored grains, especially noticeable in the dark sections of the frame. The larger the pixel, the more sensitive it is, the better it takes each detail of the future frame. Therefore, the ratio of the size of the matrix / number of pixels tends to increase. But there are reasonable limits. For example, the matrix 1 / 2,5 TODAY should not have more than 6-7 megapixels. All that is more - it makes a lot of noise when shooting with the slow shutter speeds of a house without a flash, in the evening, etc. The 1 / 1,6 matrix is larger than the 1 / 2,5 matrix by an area of 2,44 times. Megapixels on it already theoretically can be and 15-17. But it will be the same quality in quality garbage as 1 / 2,5. Such matrices - 1 / 1,6 today have 10-12 MPX, and already give a much better picture. Best matrix is 2 / 3 (or 1 / 1.5) and 11,1 Megapixels in the Fujifilm S100FS camera. And that e can not be compared with the camera Olympus E420 (it's an amateur DSLR) with a matrix of 4 / 3 and 10 MPX. For good shooting, you really should choose a large matrix - at least 2 / 3 and not more than 10-11 Megapixels. And you will be satisfied.

PS: Superprofessional camera Canon has today 21 Megapixel. But compared to the 10 cameras, these pixel pixels fit along the length or width of the frame only 1,5 times more. That is, if the Super Chamber makes a frame of 1,5 meter per meter, then the other one is a meter at 66 centimeters. Is the difference great for us, amateurs?

Visit the site ... and there compare the test shooting with any two cameras of your choice. And you will understand yourself better than all these prescriptions will be told to you. - With interest I got acquainted with the reasoning of sensible guys! Thank you!
- If from compacts, then the minimum matrix is 1 / 1.8. "Megapixelity does not matter much, usually 6m is enough.

To be non-grit, you must simulate at the minimum ISO.Mirrors for A3 any fit ..

- The basis of a digital camera is a photosensitive matrix, which is characterized by two parameters: the number of photosensitive elements (pixels) and the geometric size of the matrix itself. By the number of pixels of the matrix of the most common models of cameras are from 2 to 8 megapixels. By geometric dimensions (diagonal) from 1 / 2,7 to 3 / 4 in. Separately it is worth noting mirror cameras with a giant size of the matrix 23x15 mm. The more pixels in the matrix, the more detailed the image can be obtained. The larger the geometric size of the photosensitive matrix, the clearer the image is, with a low noise level.
For viewing photos on a computer, sending them over the Internet and printing photos of the postcard format, it's enough to have a camera with an 2 megapixel sensor. The 3 camera or 4 megapixel will print pictures from the post-format to 15x21, see. The middle peers with an 5 matrix or 6 megapixels are free to print good pictures in the format up to A4. Advanced cameras 7 or 8 megapixels can be completely printed on the format A3. All cameras with large-format matrixes allow operation in low resolution modes, saving space in the memory card if large images are not supposed to be printed

- Good!:)))
- The main question is which picture, according to your requests, can be considered "good"?

In addition - the quality of the image depends not only on the matrix, but also in a huge, perhaps decisive, measure on the quality of the lens.

I offer to your attention two pictures, very good for the cameras on which they are made.

shot on an old Canon PoweerShot A-520. Total 4 Mpix. But I am satisfied with the quality that is obtained when printing to the A3 format. (On a good, naturally, printer, on glossy paper). As others - I do not know, the requirements for quality are individual. .

Made on Canon PoweerShot A-720. Here are its characteristics (see: ht tp: // link is blocked by the decision of the administration of the project): 8 Mpiks, the size of the matrix is 1 / 2,5 "(which is certainly not much: in general, the larger the geometric size of the matrix with the same number of pixels, better.) Too cheap compact camera (usually from 6000 to 7500) ... - Mirror with a crochet factor 1,5, 6 Mp is quite enough and + a good lens.
- I can not find anything from the digital cameras, only the DSLR.

The points

1. 6-10 Mp - the more - the more noise

2. The more - the better, Not lower than 2 / 3 "
