I'm a noob with cameras, can I ask with low light shots, do u use flash? What mode do u use? Auto? Hdr? I usually just use auto for everything lol.
HDR is for when there's bright brights and dark darks, like during a really sunny day when you've also got something in shadow. So that wouldn't really be for low light shots.
For low light shooting, I tend to shoot without flash. There's a fantastic new exposure control feature with iOS 8. Lock the AF/AE by tapping and holding on the subject in your photo until the yellow box flashes a couple times. Then you'll notice a little yellow sun indicator next to the yellow box. You can slide your finger up and down the screen to adjust the exposure.
This is an amazing and easy tool which I use all the time. Obviously for a low light shot, you'd slide up a little to increase the brightness.
