To revisit , ahigh dynamic orbit photocombines multiple photos taken at dissimilar exposures to produce a individual picture that looks more like what your eyeballs are able to discover than a standard digital pic . ( dynamical kitchen range is basically the range between the darkest and lightest parts of an paradigm . chink outAnsel Adam ’s Zone Systemfor more on this . )

HDR photos lick two trouble in the iPhone 4 : Most digital cameras tend to not have fantastic dynamical range , and the iPhone 4 also miss manual control for adjusting exposure beyond tap the area of the image you require to expose for . This can have problem in bright outdoor scenery , forcing you to choose between blown out sky or shadowy human body ( see above ) . With an HDR photo , theoretically you ’ll be able to fascinate and correctly expose the whole picture , just the way you escort it before you frame it with your iPhone . ( Sadly , this is only available for the iPhone 4 , not other iOS devices . )
Freeze, sucker
In HDR mode , the iPhone 4 conquer three exposures to mix into an HDR pic : underexposed , normal , and overexposed . Even though it ’s shoot those sequence of pictures pretty fast , it ’s not instantaneous . So , if you move the telephone , or if your subject is on the running , you ’re conk to wind up with some mutant admirer with three arm or whispy specter when the phone assay to mix all the photos together . As you may see in the picture above , taken while walking , we ’ve got phantom cable car , mutant trees and weird road markings .
Focus, focus, focus
Having your matter in focusing is key to making it look aright when the iPhone 4 combine everything into a individual icon — in part , so it ’s easier for the software program to do its job mixing all of the photos together without scrambling them into a fuzzy , weird mess .
Is it an HDR-worthy photo?
The winder is to check that you have a muckle of dynamical range to capture in the first place . In other words , something with a decent range of light and dark areas . Photos that are comparatively compressed ( likein low light ) , at estimable , show no improvement or at worst , suffer when you slap HDR on ’em .

chip in the iPhone 4 ’s basic HDR capabilities , you ’ll get the unspoiled outcome with photos where you ’re seek to do basic things like properly peril somebody ’s face against a bright outdoor aspect . A pic of planks on a boardwalk that ’s already properly peril , not so much . ( When it ’s not clear what it should do , the iPhone incline to be given toward an overexposed or wash out facial expression . And with HDR in ecumenical , you definitely lose the iPhone ’s tendency toward pumped contrast and intensity , which I commonly opt . )
Play Around
The great thing about the iPhone 4 ’s HDR feature of speech is that it preserves the original photo along with the hopefully new - and - improved edition , so it does n’t cost you anything to experimentation . If you hate the result , just edit it .
The iPhone 4 ’s photographic camera wasalready awesome . While its new HDR feature article does n’t produce miracles , it does make our favorite phone photographic camera even considerably , so it ’s hard to complain too much .
