If you only want to share photos and don't need iCloud, then Adobe Carousel may be your answer.
Adobe Carousel gives you access to your entire photo collection from your iPad, iPhone or Mac. Adobe Carousel also allows you to enhance them using the same technology as Adobe Photoshop Lightroom. However, to use Adobe Carousel you'll need either a monthly or annual subscription. You can import as many photos as you want for an introductory price of $59.99 a year or $5.99 a month, although this offer expires January 31, 2012. For those that are planning on using iCloud for their Apple sharing needs, this will be a real deterrent.
The photo enhancement tool is somewhat limited compared to Adobe Lightroom but is useful for just simple effects. Most importantly, you can fix exposure, white balance, and saturation. A slider enables you to change contrast, brightness, vibrancy etc. Changes are non-destructive, i.e. they don't affect the original photos. Finally, you can create libraries which friends and family can access via an Adobe Carousel app for iOS via which they can also add photos to albums.
One other factor to bear in mind is that Adobe Carousel is very limited in the formats it supports. At the moment, only JPG images can be uploaded to it.
Adobe Carousel is very polished app and if you're not using iCloud and just want to share photos, then it may be worth a try.
