EOS R7 Auto Exposure Bracketing and High-Speed Continuous Shooting Together

[mrhengy]

Hi,

I like to do a lot of wildlife photography, about 2/3rds being birds, and I have settled on my preferred settings for my Canon R7, based on my skills, what feels comfortable, and what I feels gives me the best photos.

Except for one thing: Using AEB and High-speed Continuous Shooting (+ or non+) together. I like to bracket, because I find that with fast moving subjects, I can't react fast enough to change exposure compensation manually. I find that a +/- 1 stop both ways gives me the safety I want. High-speed Continuous Shooting should be obvious.

However, when used together, the camera will only shoot 3 frames, and then I have to release the shutter button, and press it again for another 3 frames. (AEB is set to 3 frames). Now, most of the time this is fine - it gives me time to recompose, track my subject, etc. But every now and again, I'd like to just hold the shutter and roll off more than 3 frames. I have been up and down the camera menu and manual, and I can't find a setting to change this behavior.

Does anyone know of a way to change this?

I come here with a perfectly valid question, only to get told I'm not using my camera right, no one should ever need to do that, or the two were never intended to be used together and I'm absurd for even trying. If there is no option to do what I want, a simple "no" would have sufficed.

Thanks everyone.

A simple “no” is th wrong answer.

You cannot change the behavior because the two features are mutually exclusive.  You have been provided with a work around.  Use the 2-second timer.  Good Luck.

I have exactly the same need as this gentleman.  I am not shooting birds. I am shooting the solar corona during the upcoming total eclipse of April 8, 2024.  The sun's inner and outer corona's are very different in brightness.  I need to bracket 5 exposures every time I shoot to maximize detail.  I will combine these later into a HDR image. But I want to do this all though the 4 minutes of totality. I'd like to shoot a bracketed sequence one every second or two. Haven't figured out how, yet. Maybe I should use digicamcontrol...

dduncan,

I have a T8i. I tested this out this afternoon. My camera will only take three bracketed shots: one underexposed, one overexposed, and one regular; each shot, one or two or three stops or whatever under or over exposed.

If I set up the bracketing sequence, and then go into my shooting mode and select the continuous mode (it's the one on the extreme right marked with the letter "C"), I can  choose to take 2 sets or 3 sets or 4 sets of bracketed shots. You can go all the way up to 10 sets, for a total of 30 shots.

There is a 10 second delay before the shooting starts, but there is no delay between each set of 3 bracketed shots. You can't pause it for 1 or 2 seconds between set as you were asking for.

But, I did have a thought. I did not test this, so I don't know if it will work...

Could you do a time-lapse movie of bracketed shots instead of single shots?

If you are able to take bracketed shots, you'd have allow enough time between each set for the camera to process those.

I know there are software programs out there that will convert videos to individual jpgs. They extract each frame.

Of course, if you're shooting at 30 frames per second X the 4 minutes of shooting, you're looking at 7,200 frames. If you set up a 10 second interval between each set, you're looking at 720 individual frames.

M8ght that work?

dduncan833,

Another option...

My camera has a Special Scene Mode called HDR Backlight Control.

It takes a series of 3 shots and merges them into a single image. If you combine that with an intervalometer, and take a series of shots every 10 seconds or so, that might work.

I figured it out.  Set bracketing to 5 exposures.  Set the interval timer to one second, and 20 repetitions. My R6 took 100 exposures just like I needed.  I think that I also read that if you set the interval to 0, the camera will work as fast as it can.
