EOS 5D Mark IV How to get 9 shots for exposure bracketing

[GregM]

Exposure Bracketing with Multiple Exposures with 5D Mk IV.

What I want to do.....
Take Multiple Exposures and Exposure Bracketing.
I have had some success in this endeavor.
I am working with recommended exposures to capture various instances of eclipse exposures.
Currently I am getting the following exposures....
1/6400
1/3200
1/1600
1/800
1/400
1/200
1/100
I have read that the 5D Mk IV is capable of up to 9 exposures but I can't seem to get to that with my current settings.
I do not want to combine these exposures, I want individual exposures saved.
What I would like is 1/8000 sec on the bottom end. So far the only way I can get to do that is shift the bracket but that would eliminate the 1/100 exposure.
If I can use 9 exposures I could gain the 1/8000 exposure and add to the plus side.

Is it possible to change my 7 shot bracket to 9 shots?

Custom functions in the camera only allow 7-stops at the most for any kind of bracketing. Maybe other software apps used to control the camera can deliver more stops by simply changing the exposure settings to create the sequence, though this is not possible in EOS Utility.

Your settings are set for 1-stop exposure shift for each bracket, with is basically a doubling of the shutter speed. So  the only way to get 1/8000th is to start at 1/125th. Also 1/18000 is only -1/3 EV from 1/6400.

• 1/125
• 1/250
• 1/500
• 1/1000
• 1/2000
• 1/4000
• 1/8000

My center position is set now at 1/800 sec. I can move this to 1/1600 sec but I will sacrifice the 1/100 sec shot.

I am shooting in RAW and probably I can push the 1/6400 sec to get to 1/8000, but pushing an over exposed frame is harder than an under exposed frame. I guess the only  thing to do is change the bracket and sacrifice the 1/100 sec.

Thanks for your reply.

I have a few years until the next eclipse.

Are there plans for new firmware for my camera or is support now over? 

Thanks again.

Perhaps if there is new firmware it will include the 9 shot exposure I am looking for.

In my sequence the center / initial frame would be 1/1000th.

I think it is unlikely to see a firmware update from Canon to extend the functionality of the EOS 5D Mark IV.

Is it possible to edit my C2 settings and then record that edited C2?

Or do I have to start over?

[p4pictures]

Yes you can edit the settings as long as the change is not to change the mode, eg M to Av. 

All other changes, go to the Custom shooting mode menu and then at the last entry Auto update set, make this enabled. Now make sure you are in the C mode you want to change and make the changes. These will be automatically saved to update the saved settings for the custom mode. You can switch off the auto update settings after if you want.

It worked perfectly!
Thank you very much.
