Dear all:

I am trying to use Photoshop to create a special effect for a presentation.

The effect I am trying to duplicate is the one created one a selection
window is drawn across the desktop on the Mac's OS X. When the cursor is
placed at a point of the screen, the mouse button is kept pressed and then
the cursor is dragged across in a diagonal motion, a whitish-translucent
window is created covering the objects within this window.

My need is to create this effect to mask items o a slide during a
presentation only leaving the items that I wish to focus on while all the
others appear translucent or masked.

How can such an effect be created over an image in Photoshop ?

After the image is transformed with this effect I will then transfer it to
Apple's Keynote for my presentation. In case the information helps, I wish
to have this mask used as a transition from one slide displaying all items
to the next where most items will be masked and only the one in evidence
will be fully clear and visible.

Thank you in advance for your help.

Best regards,

Joseph Chamberlain

One way is to first increase your canvas size (this is temporary) by perhaps
300%. Then create a new empty layer above the background. Press D then X
and select the Gradient tool (main pallet) with white and transparency. Now
with the gradient tool, drag from upper left corner to lower right. There is
your transition feature. You can then move it to the lower right in steps to
reveal more and more of the background. Crop the image to your final when
done. I can post an example if you like.

Something like this? (Imagine the iterations as being manually controlled
instead of animated in the example.) Shows four times.

Thank you very much for the feedback, Lorem.

I am definitively going to give it a try. I thought about creating a second
image with everything masked and only the area of focus exposed. Then create
some kind of transition from the slide without the mask to the slide with
the mask using either flash or another file type that allowed animation and
could be imported into my presentation application (Apple's Keynote).

I actually like your approach as it is probably simpler than what I had
originally planned. I am going to try it and see if it works for me.

Thank you again,

Joseph
