Quick and easy online photo retrieval
More and more people are completely satisfied with the pictures on the screen of a mobile phone or personal computer. Photos in paper form, which we can hide in our wallet or put in a frame on the chest of drawers is a completely different matter. Today you can order them comfortably on the Internet, although you need to know how to do it to make it work perfectly. In this text we will explain how to do it step by step.
You don't need a professional or professional equipment to take a good picture. No reagents are required to develop the images. Let's get down to it and pick up our photos from the courier.
In the past, we produced prints by giving the photographer a film, which he treated with appropriate chemical reagents. There is no reason to go into details here, but the procedure was to create a negative, which was then recorded on photosensitive paper. It was even a magical process, because soaking the paper in reagents and then exposing it caused a beautiful image to emerge. Today we mainly limit ourselves to simple printing.
Printing and calling
Modern cameras save photos in digital form. This is a graphic file that can be applied to paper using a specific printing method. This is called a dry photo call. Wet calling is similar to the classic procedure described above, but instead of chemical baths there are special machines that do everything for us.
Before ordering prints you need to familiarize yourself with a few basic issues that will allow us to get the right effect.
To put it simply, the resolution of images is the number of dots (pixels) that enter one image. Again, to put it simply, the more pixels, the better the image. Cameras are usually described by megapixels (written as MP or MPix), i.e. millions of pixels per photo. For a good image of 10x15 centimeters you usually need about 2MPix. If you try to take a print from a lower resolution photo, you will end up with a blurred image.
DPI is a measure similar to resolution, but it is used in printing. This indicates the number of points per square inch of printout. The higher the density of the points, the better the quality of the image when viewed from a shorter distance. Typical printing is done in 300DPI resolution, which means that if our file has a smaller DPI, which really rarely happens, the print quality will be very low.
Print Format - Framing
A typical photo printout has a rectangular format with sides of 15 and 10 centimetres. With this format, 3:2 format, most photos are taken today, so there is no problem with it. Old photos and some cameras still have a 4:3 format and you can often set it yourself. If this happens, it is necessary to crop the photo or it will be stretched or shrunk ugly.
