Long-Exposure Tutorial Part 2 - Luwian iPhone Academy of Photography
Let's review two scenarios: one during the day and the other at night. To begin capturing, adjust the frame rate and the number of images to be taken per frame. If you choose to use the countdown timer, you can stop the process at any time by pressing the stop button located next to the shutter button.
When taking neutral-density long-exposure photos during the day, a contrast is needed to make the dramatic view visible.
To achieve this, it is usually best to keep the stack image count lower number, although this depends on factors such as your frame, moving subject count, and environmental conditions.
Here is an example with Shibuya Scramble Crossing: I kept a stack image count of 35 and a frame count of 30 per second. You can set up 1 to 100 stack images per frame for 1 to 30 frames per second.
If you are taking photos of water currents or cityscapes with ocean or crowded areas and you want to make people disappear, consider using a higher number of stacked images setup.
Here is a night scene with traffic flowing. In this scenario, I keep the frame rate at 30 and stack 16 images per frame. I wanted the moving vehicles to flow like ghosts on the road without disappearing.
Let's take a moment and enjoy the final version of long-exposure photos captured using Luwian.
