The mysteries of digital photo Printing

The new issue "Friends of photography" has arrived again, and I will get it soon after work. When I came back, I went through a Kodak digital printing store (located at the Changning junction of Dingxi road near "Paris Spring"). The glass window at the door said: 6 Inch photo, gold card member 0.7/ Zhang, Platinum Member 0.6/ Zhang, I think there are still a lot of photos on hand, so I went in and asked. The boss said: one-time payment 500 RMB can be used for gold card members and platinum members 1000 RMB. I took a look at the printed photos in the store, Kodak royal photo and paper. I used to go to a COICA printing store all the time. The effect was very good, that is, the road was too far away and I was planning to change one. Think about it 6 Mao Yi is really cheap, just take out 1000 Yuan to prepare "platinum members ". At this moment, there were several people taking photos at the door, and I remembered my MP3 There are still a few photos, I want to print them out first to see the effect. So I went straight into the room.

The room was very small. Two staff members in front of the two computers were adjusting their photos. I was about to speak and rushed into a middle-aged man with a shout in his mouth: How did you print this photo? It's almost time to cut your head! At a glance, the man was holding a large pile of photos in his hand, and there was a group photo of a dozen people on the face. Everyone looked very good, however, we can see that the top of the photo is close to the edge of the photo, and the sky on the top of the photo is almost invisible. It was originally a good collection photo. Now, because everyone is "full" of photos, suddenly no beauty. When the man saw that I was watching the photo, he said to me, "You see, how can I send such a photo ?" At this moment, the staff said, "This is a bad shot. We won't have any problems here !" Then He said to me, "Do you want to take a picture ?" I think this Chinese-Indian store may have problems. I just said, "Let me take a look ". The man went on to ask the staff: "I don't have a problem taking a photo. Besides, this is the case with so many photos. How can this happen? Do you have any original photos here ?" "Yes !" The staff member immediately called out the original materials and checked out that there was no problem with the photos taken by the man. The figure was very beautiful, the character size was moderate, and there was about 1/3 blue sky on the top of the head. It is no wonder that such a film will become so dissatisfied. At this moment, the staff pointed to a sign next to them and said: This is a problem with your camera. There is no way. Let's take a look at this. When I look at the sign, it says," To adapt the printing to the standard size of photo paper, the printing output will be cropped according to the screen conditions. , After the image is enlarged, the part on the edge that exceeds the photo area will be cropped. However, if you want to preserve the image content and restrict the image to the standard photo area, Some white edges may be left at both ends of the photo. Please select it by yourself ." This means that the aspect ratio of the photo paper and the aspect ratio of the original image taken by the camera (should be CCD Or CMOS The aspect ratio) is different, so either cut a part or leave the white side. This explanation seems quite reasonable, but in the past two years, I have printed at least one or two thousand digital photos in other digital printing shops, and they were taken with different digital cameras, but never encountered such a problem. I have seen white edges around the photo a long time ago. I already think it's ugly. Isn't it ugly to leave two white edges on the left or right? If I make a cut and cut it like a gentleman's photo, what kind of face should I say that I am a photography enthusiast "?? I don't know 6 The actual size of the inch photo paper is large, but I can conclude that the size of the photo paper in this printing shop is different from that of the original photo paper! (Similarly," 6 And most of the digital cameras on the market use Sony Of CCD , The aspect ratio is 4 : 3 It should also be standard! For example, the general computer screen is 1024*768 . A picture is displayed on full screen. The gentleman used Olympus Camera, mine is Canon , All 4 : 3 The photos I rushed out before were definitely not cut down, and this store ...... Why are there different sizes in the same six-inch format? In addition, the photo size of the store is smaller than that of the original one. No wonder it's so cheap. It turns out that the mystery is here !!

Naturally, I didn't run the "Platinum Card". I also reminded my friends who need to print digital photos in this article that we generally don't pay attention to these issues. It is best to ask them clearly before printing to avoid being fooled!
