First, the electronic version of the photo requirements:

1, recent photos, clear photos, complete, background red, blue can be.

2, the photo is JPG format, between the size of 15kb-35kb: The size of the picture is 150 pixels wide, 210 pixels high.

3, photos must be taken by digital camera, camera pixels should not be less than 4 million.

4, Avatar size and Position: Portrait in the picture rectangular box in the horizontal center, the top of the head of the photo to occupy the height of the photograph 2/10, the bottom edge of the photo to just reveal the clavicle or shirt collar point. Two ears to reveal, usually with the eyes of the need to take pictures with eyes.

5, dress code: Clothing should not be similar to the background color, it is recommended to wear dark clothes, men (suits + shirts + ties), ladies (suits + shirts).

Vii. other cases (precise adjustment of dimensions)

It is rare to see whose photo is particularly good-looking, either stiff or lifeless, or seriously shape that he does not know himself. So can you use a digital camera to make a good-looking and meet the requirements of the document photo? Of course! Follow me! The basic steps for making a photo of a digital document are: According to the standard one-inch, two-inch, small two-inch, five-inch, seven-inch and other photo size requirements, the shooting of the head digital photos with a light blue background, and then proportionally reduced to one-inch, two-inch, small two-inch pictures and paste it in five-inch, seven-inch size of the picture, and then to , seven-inch photos, and finally cut into standard one-inch, two-inch, small two-inch and other documents. In this way, you can shoot and handle your own documents as you like, until you make your own satisfactory photo. This is probably any photo studio with a traditional camera can not be achieved, and the key is they will not care about your collar crooked No, the hair is disorderly, no expression done. Moreover, it is very inexpensive to make photographic documents like this.

Next, let's get started.

First step, shoot.

After dressing up neatly, sit on the chair. The light is better, the background is preferably a clean wall for later keying. Digital Camera Photo Specifications can choose "1M" above, shooting people four or five meters away from you, you can zoom in on the lens, so that the Avatar "bigger", so there is close-up effect, cross-shoot can, but do not shake. It is better to take more than one shot, and finally you can choose the most satisfactory.

The second step, keying processing.

Run Photoshop, open the selected digital photos, use the Magic Wand tool to check the character background, and fill the light blue (RGB value of 198, 202, 247), if the face has a major defect (the two days of rotten mouth), can be modified, but do not overdo it, or the document to become art photo, and then save.

Step three, trim.

1, input to the computer, with acdsee (preferably more than 6.0) to open the photo, if this photo size is 1600*1200 pixels. Select the Trim feature under the Modify menu, the software opens a new window, the preview window on the left, and the edit panel on the right. Use the mouse to resize the selection box so that the upper and lower margins of the selection box snap to the head (the top edge on the hair edge, the bottom edge at the edge of the chin), then the editing panel will automatically display the height value, if 540 pixels (head height should not be less than 300 pixels), write down this value. This is to ensure that the head in the photo to occupy a certain proportion of the size. 1.

2, according to the following three formulas, according to the height of the head just noted pixel values, respectively, one inch, two inch, small two-inch photo size, can be rounded.

One inch: Photo height = head height *1.89=540*1.89=1020

Photo width = head height *1.35=540*1.35=729;

Two inch: Photo height = head height *1.89=540*1.89=1020

Photo width = head height *1.25=540*1.25=675;

Small two inch: photo height = head height *1.89=540*1.89=1020

Photo width = head height *1.3=540*1.25=702;

3, take an inch for example, according to the photo height * Photo width =1020*729 cropped photos. Specifically, in the edit panel to enter the height value of 1020 and the width of the value of 729, the left selection box will automatically resize, drag the selection box, so that the cross-coordinate point in the selection box to the person's face tip position, and then click Finish, save the picture as "one inch big" spare. Similarly, if you need a two-inch, small two-inch photo, you can trim it by this method. This is done to make the head of the figure occupy a certain proportion in the photo.

4. Open "one inch large" with ACDSee, select "Modify Size" function under "Modify" menu, enter the photo height to 331, keep the aspect ratio, and the pixel width automatically becomes 237. Similarly, the size of two inch and small two inches are reduced to 501*332 and 454*312 respectively.

Fourth step, make five inch (seven inch) photos.

Run Photoshop, create a new white background image, size 1200*840 (seven inch for 1680*1200), open the picture "one inch small", drag the picture into the new picture, five-inch picture can arrange 9 one inch, seven inches can arrange 16 Zhang. You can save them after you have arranged them neatly. In this way, a five-inch digital photo with 9 photos is completed. The same can be produced with 4 two-inch and small two-inch five-inch digital photos. If you need to take a lot of documents can be made into seven-inch digital photos, a seven-inch photo can be arranged 16 one-inch, 9 two-inch and small two-inch photos.

Fifth step, print cut.

To the image after the printing, with scissors to small photos from five inch (seven inch) photo cut can be, the best way is to use a knife and ruler on the board to cut off small photos, remember to leave the white side oh, see their own production of the face with a smile photo, is not very excited ah! Hurry up and move on!
