The links you sent are for simulating the iris.
not the shutter.

Thanks

Well, we do what we can with the questions as they are parsed.

Back in the olden days, shutters were irises. They were called leaf shutters.

When you depress the release on a single lens reflex, the mirror swings up, the viewfinder goes black, the shutter opens and closes in two steps using two separate shutter curtains, the mirror swings back down and the image returns.
What part of that process do you want to simulate?

Forgive me, you’re the first who didn’t actually want an iris effect. 🙂
So you’re talking about a focal-plane shutter as described by David?

I think this is the part I want

[david bogie] “the viewfinder goes black, the shutter opens and closes in two steps using two separate shutter curtains”

The idea is to see the scene as if the viewer is the one taking the picture, it’s been a long long time since I taken a picture in an SLR camera, and in addition it’s a very fast movement I didn’t get to grasp.

Thanks for the explanation.
And Steve, thanks for the link.

I don’t know what you want exactly, but I made a lens aperture effect you can download for free:

That’s a bit more complicated if you want to simulate the viewfinder itself. You need to build the light meter readouts and focus screen overlays.

If all you want to do is simulate the SLR, move the anchor point to the top of the frame and scale the image quickly on the y axis only to reveal a black layer then reverse the scale. In an SLR, the mirror action is always the same but the time you’re in black, of course, is how long the shutter speed stays open.

Hi,

Go here: https://www.nyc-visual.com/movies_3.html and download the Viewfinder project.

For the mirror effect just do what David suggested or use a rectangular mask on a black solid and animate the Mask Expansion
parameter.

Salut,
Serge

hey,
Quincidently i just finished a project utilizing the same effect. What i did was use a transition ( im not too sure, I think its the “barn doors”). I played around with the transition for a while, adjusting the speed of the transition until it looked right. Then i added a new white layer behind the shutter and set the opacity to 20% or so and timed it with the closing shutter. THe result was the shutter closed with a sound effect then opend again displaying the footage that was playing before, just frozen and with a white layer on top to make it look like a picture taken with a flash. I hope you find this useful. I would post the project file, but i cant figure out how to attacth it to this post.

Good luck!
