Multiple Time-lapse time!
So I showed a little teaser in my last post about buying 8 little cameras.
These little beauties (GoPro HD) are usually used for extreme sports – Skydiving, snowboarding, surfing and the like as they’re very small, come in waterproof casings have a fisheye lens and are capable of HD. But we’re going to use them for a very different purpose.
As well as HD video they can also take 5Mpx pictures and are able to do timelapse internally – they can take a picture every 1, 5, 10 30 and 60 seconds. And as such they’re suitable for timelapse photography without a controlling computer. we already have timelapse setups using SLRs and a laptop – but the problem there is both the size and the cost. The issue with compacts is that none really (that I could find) have a suitable wide angle lenses. Most seem to end about 28 or at the extreme 24mm lenses. It’s possible to get adapters for some but that’s just another thing to go wrong. In addition the most likely candidate – the Canon G range has an issue – previously – up to the G10 you could control these via remote connection from a laptop – but for some reason – Canon decided to withdraw this in the G11 – strange.
Anyway – back to the point – we’re using them to take time-lapse photography of office installation from bare to fully kitted head office in 14 weeks.
So on Tuesday I set up 7 of these little fellas (will be 8 eventually) at the office development in Central London.
Here are a few examples:
Of course – these being fisheye lenses things are a bit distorted – but eventually we’ll correct this, including doing some cropping so that the picture fits into a standard video screen ratio.
At the moment these are are at their max time-span – taking a picture every minute.
So per day each camera will take : 1 (per min) x 60 (min in an hour) x 24 = 1,440 photos a day!
Over the total 14 week period this will mean 141,120 photos per camera!
Ok – now times that by x8 cameras!
We’ll have rather a few photos! But thankfully since we’re not really interested in night time pictures – we’ll likely delete those. Also to minimise visits to the camera (since they’re not offloading images to a laptop) we’ve maxed out the cards in each camera – to 32Gb – so doing calculations on average file size I’ll have to visit the cameras approx every 10 days. In testing night/dark shots were much smaller file sizes (~800k rather than 2.5Mb) but since this is a central London location with no curtains/blinds – there will be a fair amount of light-bleed into the building which will mean decent sized files.
So that’s what I was a bit stressed about last week – getting all the kit – cameras, special housings, chargers, various different mounts etc.
Glad it’s up and running.
Will post a bit more about the specific kit used a bit later on.
BTW If anybody does know of an ultra wide-angle compact capable of interval shooting – please get in touch. Because SLR’s have a physical shutter we’ve been killing them off like no business! Again – another post for another time 😉
