I wouldn't mind doing this one again. Motion Panning

The offroad photo thread (offroad photos, how did I do?) made me think of it.

I know we had Motion Blur this summer, but blur (intentional blurring of subject to enhance) is different than panning (blurring the background, yet keeping the subject mostly sharp).

Just a thought.

It'd be good to do a series of challenges.

Panning
Dragging the shutter
Stop motion
Blur
Shallow Depth of Field

what is dragging the shutter?

Mixing ambient light and flash in one exposure. Basically shooting with a slowish shutter speed and flash at the same time, to stop motion, but also get some motion blur around the frozen result.

Often combined with second curtain flash sync and moving subjects, to get a trail then crisp shot. Very common in wedding photography. Doesn't have to be used for motion blur though - can be used just to mix ambient and flash, to light a foreground but bring in some of the background/ambient light.

this site with some examples

To see a good example of shutterdrag, take a tlook at my headwear entry. I used this to capture many of the shots I did. Also look in just about any National Geographic, most of the photogs will shoot some this way in order to show some motion and atmosphere.

Another example of dragging the shutter.

Flash stops the motion, ambient fills in the blur and background that isn't lit by flash

For the motion panning;
When you want to see a lot of sports action it is best to do it after March. By that time all the international and local motorsports series have started again. There is not much happening at the European tracks right now.
If for some reason the challenge coincides with the Rally of Sweden (feb 9-11) I suddenly have a good excuse to go there. Cars sliding and jumping in the snow, ahhhhhhh.....

Oh yeah, my profile image is an example of a dragged shutter...well, kinda-sorta.

I really wish there were more challenges along the lines of these, and I think it would be good to repeat them or even make them for a longer period of time (like a returning assignment of sorts for a while).

Its a shame there isn't anyone on the site council reading this thread. Perhaps then they could do something. Oh...

Yeah, it would be good if one of those guys would read this. :)

Maybe we should email it to one of them.

Gordon. This would be a good subject for a separate tutorial/info type thread, kind of like how Robert (bear_music) did the Landscape learning thread.

I've heard of dragging the shutter and was not aware of how it worked exactly. Would be interesting to try it, post some pics, get feedback, etc...

Hmmm...guess I could do that in any Individual Photo thread as well, after all this is a photography site isn't it? :D

Thanks for the links and example photo's you've posted here.

It helps to have a camera with some level of manual shutter control. Either that or a camera with a 'night portrait' mode, that tends to do the same thing - fire the flash but keep the shutter open to record the ambient light in the scene as well.

It is also required to have some ambient light. Might be obvious but I've tried before to do this with either really low available light or too much of a stopped down aperture and got nothing other than the flash exposure.

The real key factor to realise is the aperture/ power output controls the flash exposure and the shutter speed / aperture controls the ambient exposure. It doesn't matter how slow the shutter speed is (beyond the flash sync speed) you'll always get the same flash exposure.

Great points. Thanks! I've just recently tried the "night portrait" mode for a halloween shot (kids in front of their carved pumpkins). Wasn't quite the right setting for an antsy group of kids. :D

Certainly need to experiment some with this. Sounds like a fun technique for certain situations.
