Very straight forward to use but with a lot of control. These are some of my fav:
Integration with Apple software
One great thing, specially for those who use Aperture, is the full integration with iphoto and Aperture. If you are using LR you will have to export your images to a folder which you will have access from inside Fotomagico, but if you are using Aperture you will able to see the Aperture Library. This means that you can create a smart folder in Aperture where you will direct all the images you want for the slide show so you can see that album from within Aperture withou having to create (export) jpgs. This feature alone will help save disk space.
It also integrates with idvd for menu creation and DVD burning
Control
Fotomagico provides professional transitions and motion effects. You have full control over how they are implemented in your show or you also have the option to let Fotomagico create the slide show for you without the infamous cutting of heads of Iphoto.
Synch the transitions to the beat
You can create markers in the music track much like you do in SIW. Then you can tell the slides to change when the reach each marker.
Output choices
This is the one that got me... you can output your slide show for the web (quicktime); for TV (4:3 or letterbox); HD; for digital projectors; it integrates with Idvd; for computer presentations and for ipods. So it has a great gamma of out "expressions".
Titles
You can create titles and animate them, fade them in and out, etc. You can also insert blank slides.
And only $129.00!!!! If you have something more complex you have to go to Final Cut Express.
I owned both SIW and Fotomagico. Both are excellent in what they do and were intended for. SIW is great for creating flash slide shows for the web and I will keep using it for that purpose. But I was looking a program that would allow me similar results but that I could easily burn into DVD and do ipod too. While I respect the direction SIW took on providing that service for those who wants them (I offer it to those clients who want to purchase the SIW slide show. They can use that choice if they want) I wanted something with a quick turnaround on DVD and ipod production that would be better than iphoto and that would not create additional workflow for me. Fotomagico it is that solution. It integrates flwalessly with Aperture and iDVD.
So, for those that are looking into slide show production tools for a MAC I suggest to take a good look at Fotomagico. If you have any questions, feel free to PM me.
PS. I don't work or have any association with the people of Fotomagico other than being a very satisfied customer that want to give a kuddo to a great solution.
