Ah - that's why. I thought it was to do with 'block size' and addressing within the SDHC cards - but it seems like its down to the 'powers that be' - why we should get clobbered another 4.9%

On the other hand as Yves points out: 'would you watch a 30 min video showing a beetle walking on ice without any cuts?'

Does the ability to read SDXC cards mean that the 25minute max for video will no longer apply?
Andy

It does - however the programme I use does a merge/ blend so each single frame actually lasts more than the 1/25sec frame rate and becomes several frames gardually mergin with those adjacent to it (if you see what I mean!) This way the time can be extended a bit and it will still look as though it flows.

Also - one might want to use intervalometer simply to take a set of stills showing, eg, a flower opening over an hour or two

Andy

I'm intrigued...

Andy

Fair enough!
Andy

But I believe it tops out at 99shots? The one I made just goes on until battery runs out!

Thanks for notification Jules

I built my own one last year (a different design to that linked to) and gives greater range of timing. Having said that I have mainly used it at 10 to 20 seconds timing.

Its been great to take 400-500 shots of a sunset/ tide coming in and then compressing in to a couple of minutes video. Set the K10D to take jpegs at its 2Meg setting and one almost has full HD video piccies and a lot of room on an SD card!

It does rather increase the shutter count rapidly though

Andy

I have done a B setting on my K10D for 90minutes followed by 90 minute dark frame subtraction - and it didn't damage the sensor! (It was powered by mains adapter)

Thanks for the link Kris - some amazing photos there! And a great story. I wonder how the guy who is trying to scan it all in etc normally earns his crust?!
