The Optimal Resolution Photos for Printing

Pixels are the smallest unit that can be represented or controlled in a digital image. More pixels mean higher resolution, resulting in a more detailed picture quality. One megapixel equals one million pixels. Modern cameras have a pixel sensor is much that is between 10 megapixels to 24 megapixels. In general, the print size is determined by how many megapixels you have, which is determined by several different factors, including the camera sensor, camera settings (resolution and image quality), and print settings (resolution).

Camera settings

Resolution of a sensor is a major concern in digital photography. Higher resolution allows for printing larger. For example, a camera that has a 18 megapixel sensor (5184 x 3456) can be used to print the image size of 16 x 24 inches with no loss of quality and sharpness. A modern DSLR camera with full frame sensor able to provide the maximum file size of about 26MB RAW, for image size 5616 x 3744 pixels. But if you save images in JPEG format, the file size will be about 6MB. So with the same camera, image file size may vary based on file format, subject, ISO speed, picture style, as well as other variables.

Print settings

In the printing business, the term means the resolution of the density of dots per inch (PPI, some people call DPI). Print resolution has strong links with visibility photograph, because the image is printed with a large size so our visibility to the photo should also farther away. For example, a 3000 x 2000 pixel image to be printed 4R size to a resolution of 200 or even 300 PPI, but when will print billboard size 6 x 20 meters then 12 or even 9 PPI PPI is enough. This is because the 4R photos are generally viewed from a short distance so it needs to have good quality, while the billboard ads do not need a high quality as seen from a distance. You can also increase the image size by interpolation techniques to allow for greater printing. Some applications such as Genuine Fractals Photoshop plugin allows you to increase the size of images using fractal based interpolation algorithms - without losing sharpness or detail that you see in the image of the sample.

So to be optimal in photo printing, make sure in advance how your camera sensor resolution, and if we know will print large size images with the image size to avoid selecting a lower resolution sensor kamera.Setelah also note the PPI or the print resolution, an image printed with PPI is low, the result will be broken, not sharp and not suitable for small sized photo (below 10R). But if you want to print very large, we can increase the image resolution (image size) with interpolation techniques or his lower PPI. Keep in mind that the quality of the image on the monitor screen still looks high-resolution photos have a smooth transition, especially in shadow areas and in areas where the dark areas should be maintained without becoming black. So although there are techniques and applications for manipulating images, but keep in mind that there are no software applications can add an image resolution that does not have sufficient resolution.
