What Am I Doing Wrong?NOT Related To A.NET Reject

Tue Apr 25, 2006 4:50 am

Good morning , afternoon or night! I have a pure photography question. Not asking you whether it will get accepted by A.NET or not, infact i am not even concerned with that. IMHO, this section of the forum is just full of that and the real photography interest has kind of died. Anyways, i have taken a few shots of a TG 744 today when the sun was setting. As you will see they are shitty and grainy and full of noise.

Please tell me what i am doing wrong. I love this kind of photography of capturing planes at their cruise altitude. HELP!

1/125, 5.6, ISO 400

I have written the settings at which they were taken, maybe it can help understanding my situation. I use the 350D with the 70-300mm IS USM.
Thanks alot

Nitin,
Check your EV compensation on the EXIF data. I've seen most people accidently reduce the EV values.

Quoting Deaphen (Thread starter):
the sun was setting.

Now thats a bad time... Low light, its always tough. And when you adjust your ISO, its bumps up the noise too.

What time (IST) did ya take the pic?

I wouldn't used ISO 100 in the setting sun unless I had a tripod.

Exposure Value. Perhaps a brush up on the manual is necessary?

According to the EXIF data supplied with these images, the EV value on both of the photos is 0.

Capturing contrail shots is difficult at the best of times, unless you have a massive 'L' zoom, with IS  wink . I am guessing that you have cropped these images quite a lot, and they will already have been taken at the 300mm end of your zoom.

I have been successful in the past with a few contrail shots using my old 300D and the previous version of your lens, so it is possible (or it was then). But I think cropping as close as you have will really show up quality issues, so I think you need to think of a wider shot with more of the vapour trail in the image (though why such shots don't get NOA_Distance is another matter!).

Another key factor is that although you have IS, for such a distant, small subject, you really need to have no blur at all. For that reason I think you need a significantly faster shutter speed. As a higher ISO setting will, by definition, increase grain - which you really do not want in a contrail shot as so much of the image is empty blue sky - you are looking at needing bright lighting; not dusk. Also - unfortunately - although I believe your new lens is a step up from the model I have, at the high end of the zoom it is almost impossible for it to produce a really clear, crisp image. So, in editing, you will be needing to beef up the sharpening etc and if this is to stand any chance, all other factors need to be spot on.

In summary, you need clear air, with a shutter speed of at least a 320th plus, I would say, even with the IS on your lens, and a more 'generous' crop.

All the best.
