One of the main features touted by Apple as being improved at the Keynote event was the addition of Photo Stream sharing in iOS 6. As part of this “Inside iOS 6″ series, I’ll be taking a look at the Photos app, including sharing and Photo Stream.

In case you missed any of the previous articles, so far I’ve covered Facebook Integration, Maps, and the App Store.

The overall user interface of Photos in iOS is very familiar. Not a lot has changed on that front. However, instead of having Photo Stream in the list of picture albums, it has its own section at the bottom in the black bar. To access the new Photo Stream sharing feature, first access the iCloud stored photos, then hit the share button.

Once you’ve selected the photos you want to share, hit “Share” and select “Photo Stream”. You then get switched through to some options. You select who you want to share them with, what you’d like to call the album, and whether or not to make it public. You then get an onscreen post update, which looks identical to the Facebook/Twitter update UI. Once shared, it shows up as a separate album in your Photo Stream. Simple.

If you don’t use Photo Stream, you do have the ability to share photos via the usual routes: Messages, Facebook, Twitter, Mail etc. You can even print them straight from your iPhone/iPad. You can also view where all your photos were snapped, using the “Places” section of the Photos app.

The biggest update is the UI of the share menu. As you can see from the image at the top center, instead of having a menu list, you get a more iOS flavored grid of icons. This ensures that more options can be fitted in without needing to scroll up and down constantly. It’s a much needed, and very pleasing update.
