Print a photograph (I) Print a picture is not as simple as it seems, must take into account several apectos, apart from pressing the print button.
Everything depends on the resolution of our image , simple cameras, the very cheap or many of the compact, have a resolution of between 72 and 96 ppi (pixels per inch ), ie a 72 dpi image of 72 pixels is divided proportionally to 1 inch (1 inch = 2.54 cm) . The lower the number of pixels per inch, lower resolution will have a picture (it is when we find some color pictures in our photo). However, if the picture is a lot of resolution, say 300 dpi, in 1 inch shall be allocated proportionately 300 pixels, see the picture sharper and almost did not see those pictures of color, because they are very small.
PROPER RESOLUTION - To view photos on a monitor computer, more than 72 pixels is not necessary, because the monitor does not support higher resolution, so most sites are optimized your images at 72 dpi, saving size and facilitating loading screen, the disadvantage is that You can print quality, but the end of these images is seen on screen, not on paper. This does not mean that you can not print photos of our little compact, but we can not make big enlargements.
- The ideal for home printing of a certain quality and even increases to a certain size, would be a resolution between 150 and 200 dpi. This resolution have limited the compact, some bridge and many SLRs.
- To trade or quality resolutions professional, at least 300 dpi. Only available in professional SLR.
Finally, to say that not to be confused; pixels per inch, dots per inch (printers).
