Adobe Carousel is a Photo Hound's Dream
Well, Adobe's gone and made a reasonable solution to the issue: Adobe Carousel.
For all intents and purposes, it's basically cloud photo storage. All images will be kept in one spot and will be available on any iOS device with an internet connection. Tweaking a photo from one (i.e. adjusting hues and the like) no longer requires syncing or transferring between systems; the updated image will be viewable by all instantly. Oh, and said editing can be done from inside Adobe Carousel, similar to Photoshop Lightroom. It certainly seems like something the photo-happy iOS user could get a lot of use out of.
Granted, all this convenience and freedom from restrictive storage capacities does have a price. A very literal price. Adobe Carousel will require a subscription which can be either monthly ($5.99) or yearly ($59.99), depending on the user's preference. Granted this isn't all that substantial when compared to various other subscription fees, and it has no restrictions so users can import, edit and browse as much as they want.
There doesn't appear to be a specific release date yet, but according to Adobe's website it should be out "soon." Likewise there's no official word on cost, free or otherwise, aside from the subscription fee. Still, this is an app shutterbugs should keep an eye out for.
