As you can see there are a fair few improvements to the iPhoneography experience as reported on iPhoneFAQ.com, but the biggest announcement for iPhone photographers was the addition of the volume up shutter release feature.
The placement of the volume up button on the iPhone makes it a perfect shutter release button and should give increased stability when taking photos.
So apart from Volume button shutter release, what else is new in iOS5 for photographers?
Lock screen shortcut – this is extremely useful, when the phone is locked simply double tap the home button and a camera icon appears which if you tap brings you straight to the camera app. If you have a passcode set on your phone this will still work, but no other access is granted, you can only take photos.
Optional gridlines to help you frame the perfect shot using the rule of thirds.
Pinch to zoom – although some may find this handy, I never use a digital zoom – it gives you no advantage as the end result is the same as cropping the photo later.
Auto exposure / auto focus lock – at the moment if you tap to set focus and exposure, your preference is reset when you move the camera around. With this new feature you can lock the focus & exposure by tapping and holding your finger on the screen.
Image editing - will now come native to to the iPhone with features such as one tap enhance, red eye reduction, crop and rotate for making some crucial adjustments to your shots.
Photo management – finally you can maintain your photos directly on the iphone, rearrange the order of your photos and create & edit photo albums.
Photo syncing -you can enable Photo Stream to sync your photos across your devices using iCloud.
Twitter - will be integrated throughout iOS, so you will be able to quickly take a photo and tweet it. Testing on a beta version of iOS5 showed the image was uploaded to Twitter’s own image hosting service so no third party image sharing service is needed.
