I learned that with each setting of seconds you set the frame on Adobe Lightroom App, you have to time yourself and take countless photos in order to get the perfect amount of motion photos and angles. It’s a process to see how motion and photo can be captured and the shapes that are revealed.
There is a clear different between the sharpness of the shutter speed 1/640 and 1/15 sec. Please add the ISOs as well. The ISO is also and important element of exposure.
