All digital images are made up of grids of small squares (pixels) camera more, with something between 2 and 12 million euros (or 2 to 12 megapixels). When you print the images, the most important thing is that the pixels must be so small that they are invisible to the naked eye. This is not possible, the pressure appears as a pattern of small squares give the dreaded "fuzzy" or "pixel" appearance, but only need to do the small the pixel?
Print resolution measured with pixels orDots per inch (ppi). Depending on the PPI increased, the smaller the individual pixels of the image and less likely you are to see them, and the sharper the pressure.
A 100 ppi has printed 10,000 pixels per square centimeter, which means that it is 100 ppi, 100 ppi, both horizontally and vertically. The consensus is that for true photo quality, you have the pressure to about 200 ppi, which corresponds to 200 x 200 = 40,000 pixels per square inch. This guide is based on viewing printsfrom a distance of about 18 cm - the average distance of visualization. If you are a print hanging on the wall, however, is possible with a resolution much lower, as it will from a distance.
The images were taken with a digital camera, have a fixed maximum number of pixels depending on the chip CCD camera. If the camera has a 5MP (5 million pixels), the model, which can easily determine the maximum size of print with the report:
Print size = numberpixel divided by the print resolution
So for a 5 million pixels at 200ppi (40,000 pixels per square inch), the maximum area of the press is:
5 p = 5,000,000 divided by 40,000 = 125 cm ², which corresponds to about 10 x12 cm.
Similarly, one can calculate other sizes
3MP = 3,000,000 divided by 40,000 = 75 cm ² 10 x 8 inches
4 MP = 4,000,000 divided by 40,000 = 100 cm ² 10 x 10 cm.
6 MP = 6,000,000 divided by 40,000= 150 cm ² or about 10 x 15 cm
8 MP = 8,000,000 divided by 40,000 = 200 cm ² or about 12 x 16 cm.
If you have Adobe Photoshop or Photoshop Elements or a similar program to do everything you can find prepared for you. Click "Image" from the main menu and then click "resize image" and make sure the image "recalculate" option is not selected (click on, if it is selected), and it was suggested The maximum size of print your image.
Many peoplewonder why all of a recommended resolution of 150-300 ppi, when their ink jet printer has a maximum resolution of 2880 dpi or higher prices. The reason is simple. Inkjet printers use tiny dots of ink in three, four, six or more colors, all colors necessary to perform a wide range of colors with a complex "dithering" pattern to reproduce.
These points are incredibly small. Dpi for example, in 2880, there are more than eight million pixels into every square inch of print.However, more than one point must be a single pixel, so print resolution dots per inch display and the print resolution is pixels per inch.
Now that you know how everything works, you will know how you can set the maximum size that you print without running the risk of printing the production of "fuzzy" determined to achieve.
If you leave the situation in the form of large prints also help you decide the value of your next-megapixel camera. So if you regularly produce 12 x 16Inch prints, which can look fabulous, you decide to buy a model with 8 megapixels.
