Thanks to the expanded third-party integration in iOS 8, app developers are able to take advantage of things like extensions for that Photos library. It also allows access to the iPhone's camera settings, and a new piece of software offers another option for sorting just that. Manual, a $1.99 add-on for Apple's handsets, allows you to tweak variables in a similar fashion to how you would with a DSLR. There are options for controlling shutter, ISO, white balance, focus and exposure bracketing. On top of all that, a rule of thirds grid keeps compositions in order, a live monitor eyes exposure and a fill flash mode tackles lighting woes. All of that may sound complicated, but the interface is quite simple, so you should be easily making your tweaks in no time -- as long as you have the latest version of iOS, of course. Other apps, like Camera+, tackle manual controls too, so you'll be able to take your pick when it comes to fine-tuning those photos.
