1. The L board can help us achieve a quick transition between horizontal and vertical shooting. The transition does not cause the framing screen to shift. 2. First of all, it is a standard quick release board of Yajia. Because of its "L" shape, we usually call it an L board, also called a vertical clapper. 3. There are Yajia standard dovetail grooves in the straight and vertical directions of the L plate. 90 degrees to each other. So it can be installed into the holder (head plate holder) from both sides. 4. When it is necessary to convert the horizontal shot to the vertical shot, there is no need to lower the camera to the vertical shot gap of the gimbal. We only need to pick up the camera and turn it 90 degrees to the left and then reload the clip to take a vertical shot. 5. This not only saves time for re-framing and composition, but also does not change the center of gravity carried by the gimbal. It can also allow the gimbal to retain more angular movement space 6. Before there is no L plate, we generally use the ordinary quick release plate, which we call "flat plate". When using the "tablet", when vertical shooting is required on the gimbal, it is usually necessary to place the camera on the vertical shooting gap of the gimbal. 7. This will cause the overall offset of the original shot, and the horizontal line of the framing will also be lowered. The problem is even more pronounced if the camera has a handle attached. 8. At this point we have to move the tripod to adjust and recompose. This wastes a lot of our time, and may also miss the wonderful moment. Therefore, the appearance of the L board just solves this problem Note: Different lighting and monitors may cause the color of the item in the picture to be slightly different from the actual item.
