[langtitle=nl]W90 used for kite aereal photograpy[/langtitle]

I am using the W90 since a few months for kite aereal photograpy.

If you want to see some pictures of the result; please check B-kites.

Still some work in discovering the correct setting:
- The camera is moving (hanging under the kite) .
- The object is mostly NOT moving (Just the oposite of sport photography)
- Distance between 50 - 100 m above the ground.

Any suggestions for better setting is fine;

Image tone: natural
Recorded Pixels 12m
Quality level ***
White Balance AWB
AF Setting auto focus
AE Metering. Spot meetering
Sensitivity 200
Iso Correction ISO 80 - 200
EV Compensation -0,3
Pixel track sr. On
Blink off
fix 200 iso
Focus: infin
Blink detection Y
Digital Zoom Y

Bert, I took a quick look at your photos on your site, and I can't think of much I'd change. They look great to me!

Thanks for the positive comments. It is quite an adventure to take pictures that way.
You're right, the pictures on the website are +/- OK. But too many of my pictures , which I did not publish, are blured, moved.
So I am looking for the best settings for rapid camera movements, The list of current setting is in my first post.

Hi Bert,
as far a I know you will get a sort of panning shot effect whenever the camera is swinging through a motion.

If it's just vibration, rule of thumb for sports is about 1500/s. and you could check your blurred pics for exposure.

Here is a detailed sketch of a Picavet suspension and I am not sure how you have fixed the camera to the kite. They talk about line vibrations ('singing line') as another source of blurred pictures. Here's another link I found useful.

I want to give KAP a try but so far have not had hands-on experience with it.

I hope there was at least something new in what I said :-)
Best, Georg

Hi Georg,

Thank you so much for your reply.

The german Wikipedia is very complete and I didn't know this web page yet.

Since my hobby is kite making, I think i understand the mechanical part (kite, line, picavet etc...) quite well. The problem is that I do not know that much about photography and more specific all the settings (beside speed and ASA-DIN) you have these days on a camera.

Hi Bert,
I knew I missed something in your webpages (for example the rig :-)

I googled Pixel Sr. and found a link which has some mixed feelings about it,
Pentax Optio P70 Review

As I said you should try checking your EXIF data for ISO, shutter speed and maybe aperture. A nice tool for seeing all EXIF data is ExifTool by Phil Harvey Simply drag your picture file onto the exiftool(-k).exe and see all the data.

You could then take some snaps handheld with intentional shaking/vibrating and test different settings.

Some more thoughts from my side about the settings:

AWB: daylight
AutoFocus setting: infinity or landscape
AutoExosure Metering: matrix/average (should meter the whole pic)
Correction ISO 80 to 200: don't know. Base ISO (best ISO) is 200?
Blink and digital SR: Off

Hey, found another link :-) KAP Discussion Page - Pentax W90 settings


Human KAPing: Paraglider winch towing south of Berlin

Best, Georg
PS: As you have a remote controlled rig you probably have figured out the right moment to release the shutter in a calm moment. Did you test the jolt/twist of your Picavet-suspension when the remote control servo releases the shutter ?
