Birds in flight and dancers
« on: July 06, 2009, 11:46:13 PM »
I think I already know the answer to this (wrong setting)  I have had next to no success in capturing birds in flight or people moving / dancing, I have noticed that even though the camera is on af-c I left it on Appeture - is that the problem?

Bird example - a700 70-300G 70mm iso200, f/6.3, 1/320, Aperture


a700 70-300G 250mm iso200, f/6.3, 1/320, Aperture


Dancer example first shot in Programme with the CZ16-80 2nd with 70-300G in Appeture

a700 CZ16-80 60mm iso200, f/7.1, 1/250, normal mode


a700 70-300G 70mm iso200, f/16.0, 1/60, Aperture


Thanks yet again (you must be getting board with my questions / problems by now)

.DAVID.

There is no Exif info on these images so I cannot see what settings have been used, or what focal lengths you are using within the lens ranges, but I think you should try upping your ISO to allow a smaller aperture (better DoF for miss focusing) and higher shutter speeds (so that camera shake is not a problem and to freeze any movement blur). Try starting at about iso 1600 and take it from there depending upon conditions/results.

I think I already know the answer to this (wrong setting)

Its technique rather than settings IMO.
Panning requires skill, and can only be learnt through practice. In the first pic the birds feet look like they are reasonably sharp, which indicates that the focus point and this is down to panning.

Difficult to pinpoint the focus point on the second shot, but is either misfocussed or camera shake.

The third shot is definately misfocussed as the people in the background are in focus.

And the fourth is like the second.

Clive will be the best person to answer, but im sure its more down to technique rather than settings, though as harveyzone mentions, you want the fastest shutter speed possible, 1/300 sec min at 300mm if not 1/500 or faster.

Thought I had the panning sorted, on race cars n bikes but not on birds it seems.

Have added the Exif details - looks like I was all over the place, must have been the sun stroke ;)

Thank you all again

Just one thing that has sprung to mind, were you using spot focus ???
If not then that would certainly make a huge difference.

As i said i could be wrong, so better off waiting for someone with proper bird in flight credentials than me. Having looked at the shutter speeds, i would have certainly been shooting wide open, espescially on the 70-300G

My opinion (so take with a pinch of salt), given this additional information...
1) The birds body looks pretty sharp, suggesting the focus and panning are fine. Wing blur is probably subject movement. Increase ISO or open aperture for faster shutter.

2) This one I don't think is in focus. Write it off and keep shooting.

3) As Rob says, this one has focused on the crowd. Possibly need to select the central focus point to ensure that the camera is not picking up the wrong subject.

4) This one is probably in focus, although there may be some camera shake (hard to tell), but f/16 @ 1/60 is no good for a fast moving subject, and that is a fairly small aperture. Open the aperture up for a better shutter speed. You could be at around f/5.6 @ 1/500.

I would still go to perhaps ISO800, possibly for all of them, to allow faster shutter speeds, and maybe more DoF.

Hi David. Thanks to harveyzone and Rob for comments.

General comments about flying birds ... mostly just reiterating the others.
- speeds have to be up there..minimum of about 1/500 and preferably 1/1,000 and faster. Some shutter speed discussion here....
http://www.dynaxdigital.com/index.php/topic,5064.msg37284.html#msg37284

- sun is great but causes issues with under wing shadows...reflections up from the water can aleviate that
- birds flying straight at you are difficult... the 70300G won't focus well on objects coming straight on..great of quartering or sideways.
- spot focus is good
- spot metering usually works best...
- close close close ... is the way to go....means less cropping...and focusing is usually easier although panning is harder.
- try to figure out places where you are able to get closer or figure out bird flying habits...
- shot and shoot and shoot...I have a cool series of one flying goose that is in my bird power point show. I took nine shots and only one is good..it is all to do with the position of the wings for appearance AND relative to the light ... geese are "easy" but only about one in one hundred shots is good.
- my camera is almost always on ISO 400 .. I will set it to 640 or 800 if necessary, but prefer to come back another time with better light. (We tend to get a lot of sunshine here so that's probably easier for me than many people.)

Underwing lighting here..

David .. here are some flying geese pix...
http://clives.shawwebspace.ca/photos/view/flying_geese_/
Very few are shot looking up..most are level or even below me...some that are low to the water have nice underwing lighting. Have a look at them and see if there are clues...

Ask away.

Cheers and good luck

Clive
PS: I will be away for a few days so may not be replying often...

I shoot a lot of birds David.  I agree with the others, spot focus only OR even better manual focus and wait for the moment as it stops the lens hunting.
In your shots of the sporting activities it looks like you could have preset the focus as the people looked to be mostly moving sideways.  Once you do not have to worry about focus just shoot when you think the action is right.

Birds are more difficult and In flight shots are easier if you start with the bird perched.  I know that this is not always possible but I will take a few shots from the distance so I have something, and then keep moving towards the target taking shots every few steps.  When I sense that the bird is going to take flight, I will focus and hope to get a series of shots as it goes.  I agree with Clive too, put it on continuous frames and keep the button down until it slows up and then delete the unwanted ones....john

probably the least technical advice but when I am doing stuff and it doesn't look right I pick the nearest auto setting  take a couple of shots look at the exif and tweak from there so for the shots you were taking I would go to sports setting and then go on from there as I tend to keep trying a bit more here and there and get further away from the settings I need its sort of a reset for me and nine times out of ten it works hope this helps
