Transitions for Successive Blurring of Images

[weiphoto]

Has there been any previous posts on doing smooth transitions when you want to do a set of, say 5-6 images, all the same, except that they are progressively blurred. In other words, the first slide would be 90% blurred (PS Lens Blur, for example), the next would be 75%, and finally the last would be 0% blur (totally sharp). I'm trying to mimic a film animation when you twist your lens to make the final image sharp.

I've tried to have 6 slides play at short intervals, but the look is that of 6 slides changing. Not the smooth gradations. I've played with making the slides parent-child, but haven't mastered making the successive slides appear/disappear naturally.

Any ideas or previous posts that you can point me to?

Hopefully, this is what you are trying to achieve.....

You really don't need five or six photos, only two. The first one should be blurred as you like for the start and the second one should be very sharp for contrast.

Place the first slide into the slide list and set a very short display time such as two seconds with a one second fade-in, fade-out transition. Duplicate this slide as the second slide with a much longer display time such as seven seconds with perhaps a six second fade-in, fade-out. Place the second slide on the slide list (the sharp one) with the display time you wish and set the transition to fade-in, fade out.

Here are two zipped files. The first is a zipped executable to demo the process, the second is the PTE and image zipped so you can see this in PTE and get a feel for the set-up. You can adjust the timings to suit but the essence is that you are fading out the blurred file while fading in the sharp one.

Following Lin's example, I think you can enhance your desired effect by zooming about 1- 2% and then back out. Do this just on the divide line of the two slides such that the magnification takes place in end of blur-slide, and contracts in transition of clear-slide. This effect can be varied depending on if you are imitating manual or auto focus.

Thank you kindly, Lin. And I will try the slight zooming in, Lumenlux.

It will take me a while to absorb what you're saying, and I have to play with the transition times. But you amply demonstrated it can be done, and as a bonus much simpler than what I thought had to be done.

Will be back to let you see what I came up with.

Again, thanks for your time and effort to provide us fellow users with your expertise.

Before I had seen Lin's reply to your query I tried an experiment with Masks to see if that would acheive your desired effeect. It seems to do the trick OK by adding a mask of the blurred image and then setting the opacity to zero at the beginning of the slide rising to 100% during the progression of the slide. I then tried it with a selective mask and zoom. This can be seen in the two files listed below. A zipof the exe and a zip of the PTE project.

Hi Alan,

I would love to see your rendition of the transition from blur to sharp. However, when I go to the links, I get the response that I need to LOG-IN or get an acceptable browser. I used IE as well as Mozilla Firefox. Is there something else I need to do to download or run the zips?

Thanks in Advance,

Wei
