How to take pictures

Try not to use short focal length, especially wide angle, when shooting to avoid serious image distortion. Later, PS software was used, although it has the function of automatic jigsaw puzzle, but it is not ideal. It is suggested that manual spelling is better, the operation steps are simple and the effect is much stronger than automation.

Briefly introduce the operation steps:

Open the first picture, click on the image-canvas size-and choose whether the other picture you want to spell is here, right or up and down. If it is found on the left and right, enter twice the width, and if it is up and down, enter the height.

After confirmation, the canvas is expanded. After changing the name, click Save Save, close and reopen, then open the second picture you want to splice, and click Window-Arrange-Tile. After dragging the second picture to another picture with the mobile tool, close the second picture.

Continue to move to the overlapping place, suitable for the back point layer-merge down, smear two pictures together with a history brush, or cover them with a stamp tool. Finally, cut and save.

Acquisition method

The copyright of photographic works can also be registered in the copyright administration departments of the country or provinces, municipalities and municipalities directly under the Central Government, or pre-registered by selecting third-party platforms such as research institutes, especially all kinds of potential copyright resources that need to prove what digital form someone has at a certain moment, including but not limited to digital fingerprinting technology, digital watermarking technology, anti-piracy technology, integrated trusted timestamp technology and so on.

A public copyright protection platform with trusted third-party group technology such as notarized mailbox can independently store certificates, authenticate the storage time of photographic works, and perform multi-latitude intelligent authentication, and its scientific nature can independently verify certificates. In the case of copyright disputes, providing preliminary third-party evidence, judicial authentication institutions when necessary, and improving the validity of legal evidence have been popular in developed countries in Europe for many years, which are a supplement to official manual registration.
