Is it possible to intentionally slow down the continous shooting mode to get a longer burst? I'm going to shoot several sequences and in order to capture everything I need to shoot for about 8 seconds.

I shoot raw.

Oh no, you want to slow it down but make it last longer. Nevermind my suggestion.

My K20D can be set to Hi and Low CS - 3 frames per second up to 38 frames (at 3* JPEG), or 2.3 frames per second until SD card is full (again at 3* JPEG)

You can go to Lo-continous but that is really slow.

With jpg you can make more pictures, but you won't get full 8 seconds on it.

In RAW you can get about 50 shots in one minute. So after filling the buffer in just over 3 seconds with 22-23 images you only get a real low next set. In jpg you can get up to about 80 images in one minute. Processing and storing is just faster.

It is nearly impossible to shoot 8 s in RAW.

* Using Low continuous shooting, you may achieve your needs (8 s in RAW).

* However you are best advised to use JPEG with Hi continuous shooting. I shot sequences longer than 60 s in Hi continuous shooting with 14 Mp [**].


Importantly, do remember:

- to kill off (swtich off) all in-camera post-processing

- to have afast card, preferably Class 10 like a Sandisk Extreme III, and

- to use JPEG.

Hope that the comments will help.

With Interval Shooting, you can fire-off sequences at 1 fps. Is that slow enough?

This is not possible with K-5. Different way of handling data makes it not an option at this time.

Thanks for all the replies!

Well, I'm going to shoot images for documentation and advertisement for my local student pyrotechnics society. So defects in the details will be very visible when you magnify it to A3. As an example, we'll be shooting an ~USD 3.000 fireball some time this winter and there will be very unusual lighting conditions with sharp contrasts between the bright sections of the fireball and the black smoke and I want to catch it all. Gas burns bright, very bright, will these contrasts be a problem when shooting jpeg? (Never really used compressed formats before since I do a lot of post processing.)

About the 100 liter fireball, do you have any idea what ISO, apperture and shutter settings I should have? (In other words, which should be automatic and wich should be manually set to what? I'll be shooting from a distance to get a nice angle, probably about 100-300 yds but we'll see. Yes, I will post pictures.

Sincerely yours.
