Long-Exposure Tutorial Part 1 - Luwian iPhone Academy of Photography
Photographers use neutral-density filters, also known as ND filters, to reduce the amount of light entering the lens. This is particularly useful when taking long-exposure photographs in daylight. In Luwian, we accomplish this by utilizing an algorithm and the power of the Graphic Processor Unit. This allows you to take and store high-resolution final images.
The camera's frame rate is controlled by two ND adjustment rulers. The upper ruler decides the number of frames to stack in a one-second frame rate loop, while the second ruler controls the actual camera frame rate. The camera frame rate can range from 1 to 30 frames per second. Additionally, you can adjust the shutter speed up to a 1-second delay to achieve different results.
After making the necessary adjustments, press the shutter button and a sub-menu containing four options will appear. If you select "BULB," then Luwian will require you to press the shutter button whenever it's convenient for you. However, if you choose the 5, 15, or 30-second timer, then Luwian will automatically trigger the shutter button.
