ISO-Exposure Question
What ISO-exposure settings work best for AP(slight vibration from heli)? Im having trouble with my pictures they are blurry even though I have isolated heli vibrations as much as possible (T-rex). My camera is a Sony Cybershot W-30.

ISO only gives you the choice of film for set light conditions

Hello again cranester,

All I don't know about your camera was just learned by quick scans at:

http://www.dpreview.com and http://www.steves-digicams.com . Both locations have good forums that I have used before. You would likely get better and more specific answers from either one of them.

Your camera does not appear to have directly accessable manual settings for aperature and shutter, but it does look like the "Program mode" will allow for some changes. Generally the best quality images can be achieved by using the lowest ISO setting that suits the lighting conditions. In cameras like yours, the ISO setting can effect what range of shutter speeds are available to the camera. Your camera is reported to do very well at ISO 400.

The W-30 has a aperture range from F2.8 to F5.2 . Many cameras have a 'sweet spot' somewhere in the middle. The smaller the aperature (larger number), the greater depth of field, but this often means needing a slower than ideal shutter speed to compensate, which can let motion blur slip in.

Because you don't have shutter or aperature priority capabilties, you are going to have to learn about the 'program mode' and also 'scene selection.'

For fiddling around purposes in bright outdoor lighting, why don't you select ISO 400 and then do what you can to get a shutter speed of at least 1/250 (or higher). It might be best for you, at this point, to let the aperature sort itself out.

Do you know how to view an images EXIF information?

(don't nobody crucificate me for any accidental or just flat wrong statements - *it happens)

Boidman, Thanks alot for the help I`ll try your suggested settings early tomorrow, I'm kind of scrambling here since I just got the camera today and need to do some AP for my father in law tomorrow noon. All I had time to do today was try out the landscape mode which gave some pretty good but slightly blurred pics (I want perfect!) So I'll do as you said and see.

Thanks for taking the time to help me out.

If you don't know how to view an images EXIF information, you may have problems trying to determine why your blurring is occuring.

Start with the fastest shutter speed your camera can handle and work down from there. This will probably be 1/2000 or 1/000 sec. You will have to open up the iris as well, which will be f2-f5. Set your focus to manual and infinity. These settings are for bright midday sunlight. Do several tests and note the settings. Only change one setting at time.

If you can smooth out the vibrations, you will be able to shoot at slower speeds and with less available daylight.
