Alternative Form of Bracketing

[BoySpot]

One of the things I would like to be able to do is to take a series of shots of aircraft but playing with the shutter speed instead of the aperture. When it is passing I don't have time to change settings but some times varying the shutter speed can be beneficial (prop blur etc). Does this make sense to everyone and is it relatively simple to do?

Thanks

You have plenty of time to change shutter speeds, unless of course the aircraft are at 50ft AGL and doing 500 knots. :)

Put the camera into Tv mode (shutter priority). Take first shot, roll the wheel by your shutter finger to a new shutter speed, shoot again, roll it again etc. You should be able to do all this with the viewfinder to your eye while panning with the aircraft in view.

Sure, it'll take some practice, but you can certainly do it.

I have done quite a few shots of aircraft in motion, and I will second Ian's suggestion. I would also recomend that if you want to have good shots if the aircarft is actually flying dont use sucha high shutter speed as to stop the motion of the prop. I like to stop the forward motion of the aircraft and have the prop blur be a couple times the width of the prop blade so you can tell how many blades there are but still tell that they are moving.

If your in "TV" or Shutter Priority mode,. you change the shutter speed simply by rolling the finger dial above the shutter?

yes
i have been playing with av this way.

Some of the aircraft I am interested in are at just those sort of speeds. I am interested in getting the shots of in very fast order before the image changes signficantly. If that is the only way, never mind. Perhaps it is something else that can be built into future control systems. I would quite value the ability to have a selection of shots with varying ISO and shutter speed. See if the lower speed shot is acceptable and accept the noise if not. Does this make any sense? Maybe it is time to expand the concept of bracketing now wwe have cameras that can change the ISO at will?

How about you go to Av and bracket there?

Aperture is gonna stay the same, but the shutter speed is gonna be bracketed...

Is that gonna do what you want?

I don't believe what I want is possible yet. The sort of situation where this is an issue is when light is not at a premium and the lens is pretty much wide open. What I would like is to be able to get a quick series of shots with the fastest shutter speed possible and increase the ISO to help things. I guess I haven't explained this well before. That way, I can try and get a good shot with the lower speed and less noise and, if that doesn't work, accept the noise for the higher shutter speed conditions. There isn't enough time to try this manually when the aircraft is passing by. If you look at some of the low level fighter shots on airliner.net, you will understand how the shooting conditions can be marginal.

I guess I will have to wait for this sort of functionality. Maybe Canon will read this and add it to the firmware of new models. There is no reason why it can't be done. It just wasn't something that could be done with film so isn't in the present design philosophies.

Ah just shoot it at 1/2000 and motion blur it later in photoshop :) I hardly even see the need for 2 stops of EC either way when shooting RAW. Why bracket 3 shots at a time when you can adjust exposure in the RAW file pretty much the same way (assuming no data loss from under or overexposure of course!)
