Well, playing with DOF and aperture showed up some great results.
Now it's time to get a hold of the Shutter Speed.

Unlike the aperture, the shutter speed controls the motion blur. It also can greatly affect the long telephoto shot: the rule of thumb here is to select the shutter speed to reverse of the focal length, e.g. if you're shooting at 400mm then you may wanna use the shutter speed at least 1/400th of a sec to avoid the handshake blur.

Now, what do we do for this class?

Just like with the DOF, we're going to submit at least two shots per each entry. One shot should feature the subject "frozen". The other one should show some blurring (and I'm not talking Photoshop!).

Typical blurring subjects: hummers, Hummers, Hummer drivers walking, etc. Running water also usually provides for a steady moving target.

As with DOF, try not to change the focal length or camera position between the shots. Obviously, tripod would help, but if you don't have one handy - that's fine, too (remember - we're casual here:-).

As always, nice looking final images are very welcome, but the most important thing is to fulfill the assignment: get at least two shots of a moving object with two different shutter speed values.

For the educational purposes, please specify the following info:

• With each entry: camera and lens used (so we could figure out the crop factor and such:-). Also, if the lens is not prime, the focal length used (it should stay the same for the entry)
• With each image: the aperture, ISO and shutter speed used

For the rest of the basic rules and index please check out this sticky.

Let's speed that shutter!

PS
Thanks Rutt for discussing the class' subject!

I apologize for the late announcement, our network was down at work...

Well this is different.

Very creative! Awesome entry! Good thinking!

Quite overcast and dark today.

Another creative use of home appliances:-)
Too bad the second shot could not "freeze" the blades.
Do you think you could go ISO 3200 and set the speed to 1/500?

No 3200? I thought you're a Canon boy:-)
Well, if 1/2500 doesn't stop it, I don't know what will:-)

Hi I'm new here :)

My first assignment...
Oh and since I missed a few assignments I've put a Tilt in it ;) (assignment #5)
Shortly after, the neighbour took the laundry down...If I get arrested for being a pervert I'll say it's Nicholai fault.

1/500 f/5.6 ISO 200


1/6 f/32 ISO 200
A bit on the bright side maybe :)

Welcome to the class (and to the Dgrin, since this seems to be one of your first posts:-)!

Very apropos entry!
Yes, the second one it a tad too bright, but, hey, who counts:-)
Shooting the wind is fun, no?

I have stuff and an idea of what I want to shoot... just haven't gottn around to it and I can't find it in this town... Don't want to give it away or spoil..

Watch out, man, we got rules here: no entry - no posting:-)

Curious what you're gonna come with:-)

Cheers!

Shot with the 200mm f/2.8 with a 1.4 TC on a tripod with a remote and mirror lock up.

ISO 640 f/4 1/4000


ISO 100 f/45 1/2 + circular polarizer



1/4000 is really required to stop motion on public fountains; 1/2000 didn't cut it. 1/2 second is really not slow enough to get the nice smooth effect of motion blured water. I used the overcast morning and the polarizer to cut down on the light but it wasn't enough. if I wanted to regularly take feathery water pictures I'd invest in about 6 stops worth of ND filters.

This is a fountain in a duck pond so the water is kinda murky as you can see from the greenish cast at the base of the fountain. I think BW conversions of these shots look better because the water looks cleaner but it didn't seem to be in the spirit of the assignment. Also the second shot could use some more contrast because the motion blur washes out the highlights, but I kept the processing the same to stay on point.

Thank you for a nice entry and a great analysis!

A little late, and there's no photographic quality to these... but it was fun.




All taken with my 20D and 70-200mm f/4L at 200mm (effective 320mm). I was in TV mode, so the aperature was floating to whatever. ISO800 by accident (I always forget to check my ISO!).

1/8000, f/4
1/800, f/11
1/250, f/20
1/125, f/32

Definitely hand-shake evident on the last one, and the copter was drifting slowly in the wind.

LA's finest... (1/1250, f/11)

Thanks!

It shows very clearly that the nice prop blur requires shutter speed around 1/100th of a second. And it also shows that's it's very hard to shoot a moving target at that speed. This was a hovering chopper, imagine WWII fighters...

Cheers!

Rather basic, but it's dark when I get off work... and it's been rather rainy today... so I'm making do with what I have available inside.

Nice entries!

I only wonder what caused the color shift between them?

The flash in combination with the time the shutter was open? It was really bugging me too... the one w/ the faster shutter kept doing the darker colors, I like the longer shutter colors the best. Still getting used to operating this thinger...
