FYI – I think there might be a slight (10x) error in your calculations above – you say that 1/60th is a 166ms exposure – I believe it’s a 16.6ms exposure – so I think the speeds you should probably be aiming for are around the 1/8th for the example and then perhaps 1/2 a second for a level of reliability
I think the paragraph quoted below is supposed to read “the third photo will be TWICE your middle exposure”
If they’re both half your middle exposure that’s just no good.
“If you choose EV 1, there will be 1 stop between each exposure (that means that in a 3-exposure HDR set with EV1, the first exposure will be half your middle exposure, and the third photo will be half your middle exposure. For more about ‘stops’, check out this handy Wikipedia article).”
I am new to HDR, so pardon my ignorance. Regarding Rodney’s post, if Triggertrap works best at shutter speeds of 1/8 second or slower, isn’t that too slow for most daytime HDR photos?
That’s why we specify that it’s Long Exposure HDR. It takes some playing around with your camera settings, but you can still get some wonderful daytime shots. Have a look through our flickr group for examples of what people have achieved: e.g. this, this and this.
Yes it is too long for Daytime, but you can compensate it for many sItuations using high apertures or nd-filters. for fast shutter speeds you need a notebook and a App like “sofortbild” (mac). I use Triggertrap as a low weight variant of my macbook, and shoot my most HDRs at night, it´s nearly perfect for that.

Great catch, and I’ve updated this. Thank you!
Ken – you actually mean that the -1ev exposure will be half the middle exposure and that the +1ev exposure will be twice the middle exposure.

Is there a way to incorporate taking HDR exposures with “mirror up” mode? A workaround or perhaps a future upgrade release
