I am a Nikon D90 user and fairly new to photography. I am considering purchasing a wired remote shutter release as intervalometer for taking time-lapses. However since I'm also a fan of HDR, it will be a matter of time before I want to experiment with HDR time-lapse.
My question is, will any intervalometer work the same? Or do I need an HDR-specialized intervalometer?
An example intervalometer I had my eyes on that is relatively cheap and has the full features: http://cgi.ebay.com/130338921382
I have also seen expensive ones mentioning they take HDR time lapse: http://www.promotesystems.com/products/Promote-Control.html
Thanks in advance. :)
EDIT:
I was inspired by Philip Bloom's HDR Time-lapse tutorial and it seems like his intervalometer(s) do more than standard interval with auto-bracketing on camera. Instead of "[ev0] [wait] [ev-1] [wait] [ev+1]...", it seems like his intervalometer(s) are doing "[ev0] [ev-1] [ev+1] [wait]...". Is that right??
EDIT2:
After reading John Rappold's article, I think the reason most shutter releases ask you to set to bulb mode is so it can accurately time the shutter open time. Does this mean if I set "hold time" to 2 seconds, use continuous mode and takes 3 brackets of 0.25sec, 0.50sec, 1sec, it will produce the desired result I seek for??
