Pre-emptive photos as cameras take shots before you even press the shutter and/or taking video before/during/after and allowing you to select is a growing feature in smartphones, most recently shown off in HTC One’s ‘Zoe’ camera functions.
You can sort of get this feature with Burst Camera for Symbian.
Although it’s not as fast (that ‘Processing’ delay) or as slick as on the One, Burst Camera on Symbian is still a very useful facility and has earnt its place on my Nokia 808. Whether it’s snapping someone in a running race or trying to get the perfect shot of a baby or shooting steam trains(!), you can now get just the split second shot you need, provided you’re happy with 2 megapixel resolution.
