- Price: $79 (iLife Suite) unless you just bought a mac.
- Editing Tools: Auto/manual red-eye correction, retouch tool, contrast and color options.
- Organizational Tools: iPhoto allows you organize your photos with face recognition. Thus, you can assign a name to someone's photo and then find all photos with that person (pretty cool). You can also organize your photos by event and place (also very handy).
- Online sharing: iPhoto allows you to upload to three places: facebook, mobileme, and flickr.
- Operating Systems: Mac OS X only
- Price: Free.
- Editing Tools: Auto/manual red-eye correction, retouch tool, contrast and color options, B&W focal point, soft focus point, and much more.
- Organizational Tools: Picasa automagically finds all photos on your system when you first start it. You can organize by album or by folder. Either way, you have to assign new folders to photos that you import. Picasa does have face recognition, but it doesn't allow you to assign faces to names like iPhoto.
- Online sharing: You can blog right from Picasa. Thus, you just click on the images you want to upload to your blog and you click Blog This. You can also upload to your gmail Picasa account online. In addition, when you click on the Shop button, you can upload your photos to a whole bundle of different printing shops (this feature is extremely easy to use). Some of them include winkflash.com, shutterfly.com, walmart.com, and snapfish.com.
- Operating Systems: Linux, Mac, Windows
So, who takes the cake? That's for you to decide. I love the fact Picasa is free. I also love its ease of use when ordering prints. It is much easier to upload photos from Picasa than from any other web interface. In addition, when blogging with photos, Picasa is a must-have. It makes blogging extremely easy. Will I use Picasa on my mac? Maybe, for now I will still use iPhoto. However, most of my photos are on my Linux machine anyhow and that is where I use Picasa. If you don't use a mac, Picasa takes the cake, obviously.
Good luck deciding. If you are curious about Picasa, give it a try. It's free and it won't hurt to try it.
Try Google's Picasa!
