Now many photography studios in Chongqing have wedding follow-up business, which is no longer the pre-naval era. However, due to the rapid changes in the scene and changeable lighting, some wedding photographers in Chongqing are not familiar with the scene for a long time. At this time, I suggest that after you arrive at a place, you should first browse the various environments and have a general understanding of the scene. The follow-up of the wedding in Chongqing is mainly divided into several parts, the new family, and then moved to the location. Step 2, put the white cards you have prepared in your scene, with the white cards as the main body (remember to let the white cards occupy the whole picture here). Step 3, aim at the white card and adjust the white balance of the camera to a custom white balance. Step 4, press the OK key to record the white balance data just now, and then lock the white balance. Of course, you can't handle all the scenes after setting the white balance once. When you shoot more times, the original white balance is invalid, that is, it is no longer so accurate. At this time, you only need to reset the white balance once, repeat the above steps, and proofread the white balance for dozens of seconds.
