Help with high speed

February 1st, 2012
I am working on high speed captures and am just a lot lost. Here is my first attempt, I was trying to "freeze" the motion of the jelly flying out on impact. I cranked up the ISO & shutterspeed and set f-stop to 16 as I was outside. The high speed shutter was too dark, so I took this one on a lower speed. Not the look I was after. Any tips?

Hi :) if you want stop motion, you need a lower # on your aperture ring and a higher denominator on your shutter speed. 1/320 is fast enough to stop motion, but if you opened your aperture up to more like f/9, you could proportionately increase your shutter speed to 1/1000. I think ISO800 is a little too high to begin with if you're outside in daylight - you should be using ISO200 or ISO400. Just remember if you change your shutter speed, you have to change your aperture proportionately or the exposure will be off.

Thanks so much for your help @sdpace. I am still struggling with the "golden triangle" of iso, apeture and shutter speed. But I guess that's what this project is all about :)

@sdpace
thanks from me too. I'm such an auto shooter...but am learning a lot from this site. I copy and paste a lot of the replies to peoples questions and have the folder in with my photo folder...just added this one. Don't understand it all exactly yet, but i will in time

There are really two ways to capture high speed action. 1) using your shutter speed 2) strobes.

Here you just need to worry about number 1.

You had you shutter speed at 1/320 crank that puppy up to 1/4000 and I bet that will stop the jelly. :)

The problem you will have is that the image will get dark, but let the camera sort that out by putting it on TV mode.

@onie @staceymoo no problem :) this has a pretty easy visual to understand, and once you get it you can make your own to keep handy if you need to :)

Oh sweet @agima. I just worked out how to find the exif info after reading your post. What a newb! Thanks for your help, I have never used the TV mode, am too busy being a smarty pants and trying to do everything in full manual ;)

@staceymoo practice. NOT being insulting, but it is clear you are working on it. even with the golden triangle, each shot can be different. 320 for stop motion can still be slow depending on what you are shooting, BUT the fact that you are learning is more important than the shot. a suggestion... try the same shot 6 months from now, while keeping up the studies and learning, you will be amazed at the difference - beyond just the shutter speed. PLEASE understand i am not meaning anything insulting by that, in any way shape or form. happy shooting!

@cchambers that's not insulting at all :) I joined the project to get better with each month, learn new things, and get some wonderful advice from people like yourself. I will definitely revisit this one in time. I'm looking forward to spending some time next year looking back over how my photography has changed. Thanks for taking the time to reply.

If you really want high speed shots, use a flash. If you use a low powered flash, the flash duration is often 1/10,000 second or less. This is much faster than your shutter will go, and you won't have to crank the ISO all that much.


This image of a water drop had a 4 second shutter speed. I had to make sure the ambient light was dark enough to not make a significant impact on the frame with such a long shutter, but you can clearly see there is no motion blur at all.
