You took pictures with your smartphone, everything was contained, you immediately ran home to be able to better observe your shots from your computer but, in doing so, you realized that the final result was not exactly what you expected. I bet you were disappointed with the resolution of the images. Did I guess? Well, then you don't have to worry, there is a remedy for everything. By following the instructions I am about to give you, you should in fact be able to cope with the thing by going to increase the resolution of the photos. Well yes! Believe it or not, by using some special programs (but also online services and apps for smartphones and tablets) it is possible to improve the display of photos by intervening precisely on their resolution.
Before indicating which solutions to use for the purpose in question, however, there is one important thing you need to know: the solutions I am about to show you can be of great help but, keep this in mind, they cannot work miracles: if the basic resolution of the shot is low, you will hardly be able to obtain an excellent final result (as the enlargement of the images in post-production always involves a reduction in their visual quality). A different situation, on the other hand, concerns the modification of the resolution of the photos before they are taken, by acting on the smartphone settings.
Having made this necessary premise, I would suggest not to delay any longer and immediately take action. Therefore, identify the shots on which to go to operate, make yourself comfortable and concentrate on reading everything reported below. Are you ready? Yup? Great! Then let's proceed.
