Props + Large Jets

Sun Feb 17, 2008 4:53 pm

Hi, I was wondering about some feedback on these shots, and whether it is more desirable to have propeller movement rather than stopping it all together with a fast shutter speed. Do you think these meet the mark? Thanks

Also, I was taking quite a few pictures of larger aircraft, but found them to be not so sharp, I seem to be struggling a little with the autofocus, though I wonder whether I should stop down from f/4 some, make the IS work for its money, might it sharpen results in circumstances such as the following?

Hi,

the first two are soft and G-GMPB is too low in frame.

The Dragonair Cargo is blurry and much too low in frame. I think there is also some heat distortion visible.
The BA 757 is backlit, blurry and too low in frame again.

The last two are unfortunately not savable.

For gintojr08_1.jpg, it needs slight counterclockwise rotation. And it looks a little bit soft, and the tailfin is a tad blurry.

For gmpjr08_1.jpg, it looks soft in places. Selective sharpening is needed. The plane is a little low in frame, and there is too much space ahead of nose.

dragair_08.jpg is blurry and is affected by heat haze. And I think ba757_08.jpg is also slightly out of focus.

Yeah, I haven't uploaded the last two nor expected to salvage them, rather was wondering about some advice on improving that kind of shot. I rather new to aviation photography, and just looking out for some tips on capturing sharper images across larger jets, specifically using the L lens at the long end, since I'm happy with focusing on the smaller ones but struggling to lock onto the right areas on anything much bigger.

As for the photos I submitted, is it desirable then to place the aircraft as dead centre as possible? In terms of being soft, any particular part, the overall image, etc?

Thanks!

Hi,

had a look at the EXIF data of the Dragon Air shot. Considering your settings (f 4.0, 1/6400), the focal length and your camera and lens the result should have been much better. Beside the heat haze which destroys it partly there are some very blurry parts (eg the tail).

In these light conditions I would set it to f71 in aperture priority.
