Faking a Long Exposure

There is a lot of computing power in an iPhone. One of Sue's tasks was to shoot motion or blur in a long exposure. Well, an iPhone doesn't do a long exposure per se, but it does have a work-around to create the effect, at least in some situations.

With her iPhone 13, she can use Live View, which will, in effect, take pictures/video for a few seconds with one press. You can then tell it to do several things, and one is to mimic a long exposure.

Once again, I was the faithful subject, this time on my bike in the park.

From Sue taking a single Live View exposure, I am able to upload three results: two photos and one video. Here, in order, are the freeze-frame, the blended long exposure effect, and the video. It turned out that a bicycle goes a little too fast for a good long exposure. Someone slowly walking a dog should work better.



Here's another series.




You can create something similar in Photoshop. I have experimented with the effect a few times when I have been unable to take a normal long exposure but desired a silky water effect. For this ↓ photo from 2017, I took 22 hand-held photos and then blended them in Photoshop. I think that I have another, better example somewhere, but this one is good enough for demonstration purposes.

  5. Great photos! (and excellent subject) I love how much Sue is learning about her phone. I should do the same.

  6. The Photoshop version works well.
    The phone version doesn't.

  7. I am in awe of what you did with “Live”. I have had it OFF because it was annoying me in my just run-of-the-mill static shots.

  10. Interesting. I mostly used long exposure for dark situations and still subjects.

  11. And now I learned something new that I didn't know before! I liked the show of the disappearing AC.

  12. Wonderful lesson. Back in the day I took lots of blurred photos of gymnastic's moves, some of them even on purpose.
    That tecnique would be wonderful with a canoe and some rapids.
    Nice shirt.
