Promote Control 2 of 2 - HDR Capture for Nikon Canon DSLRs

Promote Control HDR capture device. A deeper look into operating the Promote Control and operation using the buttons and LCD. Control your Canon or Nikon DSLR with the Promote Control. Setup large brackets for capturing huge dynamic range scenes without touching your Nikon or Canon DSLR. The Promote Control allows you to go well beyond the auto bracketing settings of even the highest end Nikon and Canon DSLRs and turns their lower end DSLRs into HDR machines.

This is an initial preview of the Promote Control for HDR Capture. A future video series is planned to show best use and tips and tricks while working with the Promote Control for High Dynamic Range Imaging.

Hi,,,, My usual HDR practice is keep decreasing the shutter speed and looking at the histogram until no back tone in the image.

Can I use this Control to just change the shutter speed remotely?

Pls advise..

Thanks in advance :)

@paulhung2000 yes

Ah yes. Had to do the math in my head.

So if the scene base exposure is 1/8 for example

1,1/2,1/4,1/8,1/15,1/30,1/60,1­,125,1/250

And I want 9 shots each with the above exposures then I have to set the camera at 1/15 not 1/8

@qc2e No. You don't set the camera. The promote control ignores the camera. It controls the camera. What you can do is set the camera to Aperture Priority to see where the middle exposure would be so that when you switch the camera to Manual mode you then know what mid value the Promote Control should be set to. Camera has to be in Manual Mode, but the Promote Control does NOT read metering data from the camera itself. Download the manual from their site and read it before you buy.

Can you control the amount of fstops above and below the mid, or does it unfortunately shoot the same amount above and below ?

If so maybe they would do a firmware upgrade.

I sent promote a request ticket.

Hopefull

@qc2e You can't think of it like AEB. The camera has to be set to full manual so there is no "mid" per se like with Aperture Priority. You determine exposure. So you are determining how many shots to take. 3, 5, 7, ...... 33, 35, 37 shots... whatever. It will take an odd number of shots. You determine the range. It starts with fastest shutter speeds first and ends on slowest shutter speeds. The LCD shows you fastest, mid, longest shutter speeds as you change the settings.

Sorry, forgot to be precise. 5 would definitely cover the entire range, but 7 and 9 would be overkill (my camera can do 7 and 9).

Quite often just 3 bracketed images would be enough....

I'm confused....

Why would you need to take 19 or more pictures to capture the full dynamic range of a scene ??

Surely something like 5 would do it ?? Most Dslr's have around 6 stops of dynamic range in them so to take 5 pictures would cover the entire dynamic range of the human eye ??

I can't see why you'd need 19 frames each with a tiny variation on EV between each one ??

Most HDR books tell you this.

What plans do you have to include cameras like the NEX and alpha Sony systems?

This is mostly for canon users nikon don't ne'er this from nikon d200..d300s..d700..d3..d3s..d3­x...they all do that automatically..for me it's a waste of money for canon users..it's a gold mine and add nikon d7000..which I hate that camera for messing out of aeb. And they melted to 3..cheers
