iPhoto 5's dissolve feature is flawed. It does not transition smoothly. Instead, it darkens about 25% between images.

Unacceptable.

How is it "unacceptable"?!? It's probably using a nice logarithmic scale, which means that full brightness (i.e. when fading from a full-white image to another) would only be found at the beginning and end of the transition.

I don't see the problem -- they chose a very visually appealing transition.

I haven't used iPhoto 5 yet but I think I know what you mean-- they're crossfading the alpha of both pics instead of leaving the old one constant and fading in the new one.

Log a bug on it so they fix it in 5.0.2.

When the intensity of both images added together, you should get equilibrium. Without equilibrium, it does not qualify as dissolve.

define "nice logarithmic scale". Cut that jargon most people don't understand. If you have seen a multiple-projector slide presentation with computer-controlled dissolving unit, you would understand what I mean. If the multi-projector Hasselblad slides operated with visible dimming in the transition, owners would have thrown those $5,000 projectors back at Hasselblad.

You may want to have your eyes checked. It's not appealing at all compared to version 1-4. AFI (American Film Institute) uses this feature to chain storyboard frames together so the transition is seamless. Now version 5 dims before the next dimmed image comes up, so it's not seamless any more.

I have already spoken to Apple and we are in agreement that the dissolve transition needs work, so it will be fixed.

Kiss good-bye to your "nice logarithmic scale" and "appealing" dissolve transition, because it will be fixed.

I just want people to know this flaw before they install iPhoto 05/iLife. At least take a look. Before rushing to an opthalmologist, just do a side-by-side comparison if the difference is not abundantly clear to you.

We're not at home to Mr. Grumpy.

You are a typical Apple-apologist.

An aploogist already responded by saying:

It's a nice effect.
I don't see the problem.
I don't think it's a problem.

I am only hopeful that it will be fixed, but I am not holding my breath. After all, there are plenty of shareware applications that can do it much better than iPhoto.
