Exposure bracketing

This was touched on in another thread recently. I have been trying a bit of tonemapping/exposure blending using Photomatix recently. I have tried using the bracketing function on my E-3, and also in aperture priority using exposure compensation (up to +/- 4 stops). This takes a while and there is a greater chance of movement in the image.

I know that I am stuck with +/- 3 stops using the in-built bracketing function. But I am unsure that if I stick the camera on high burst mode, will one press of the remote release (the proper wired one) give me the 5 exposures that I require, and then stop, all within a very short space of time (depending upon the shutter speeds that are selected each side of zero compensation)? Or will my E-3 carry on shooting 5 frame bursts at differing exposures?

Hopefully, someone with have an answer as I don't seem to be able to find this info anywhere else. guys!

Re: Exposure bracketing

It stops after the range has been completed. This is how I use it, to save counting or checking that the requisite number of exposures have been taken.

Re: Exposure bracketing

Thanks. I had a feeling that this was the answer but as the camera is so quick I would not be sure of the actual number of images taken.

Re: Exposure bracketing

Yes you can bracket and shoot a burst of 5, been doing it all morning.

Worth checking each time that the bkt has stopped flashing in the viewfinder, otherwise the next sequence will start on an exposure you are not expecting.

Remember dark frame subtraction will not happen in burst mode, can be an issue if shooting inside or in poor light.

Re: Exposure bracketing

Could I ask a few questions to clarify please

If the E3 is set to bracketing mode and continuous shooting mode

1. Just pressing the shutter once will only take one exposure? (unless you hold it down)
2. If using an infrared controller pressing once only takes one exposure
3. If using a wired remote, do you hold it down while the E3 fires off 5 exposures, or press once and the camera continues the take all 5 shots

Nick
What is dark frame extraction?

Thanks Phil

Re: Exposure bracketing

If you select Sequential Shooting to high burst mode and enable Bracketing then by pressing and holding the shutter button the camera will fire off all shots in quick succession. Pressing the shutter button again will rattle off another 5 shots (in your case)

If you don't enable Sequential Shooting then you have to press the shutter button 5 times, watching for the Bkt icon to stop flashing as Nick says.

It is much easier to use with Sequential Shooting enabled as the camera will automatically stop after the shots have been taken. With the manual approach it is very easy to take an extra shot and go into a second sequence.

You have to keep the shutter button pressed until the camera stops. If you press and release quickly and say only two shots are taken, then the camera will take the next 3 on the next press and hold. Pressing the release just once quickly will result in just 1 shot being taken, 4 more will then be taken on subsequent shots.

The remote cable works exactly the same as the camera button but you can also lock the release with the remote cable.

I think that the infra red remote requires 5 separate presses (?)

Yes - it is one 'long press' - which is why I made the point about checking the bkt flash, if you let up the pressure then it will stop short (say at +1 ev) which means the next shot will be at +2.

Dark Frame subtraction is when the camera takes a second picture with the shutter closed - then subtracts that from the image removing any (most) pixel noise. I find it useful in churches as the exposure times at +2ev upwards can be quite long.

It shows up as Noise Reduction (NR on the info screen), and you know it happens because the camera sits there telling you it is 'busy'.
