Taken last night at Patricia Beach on Lake Winnipeg.
something seems weird about the trees. the star trails look good, but the trees... i dont know they look artifacty...
You are correct. The original image was a bit noisy, so I processed it with Neat Image. I'm still learning how to use this software, and the "artifacty" trees are the price I had to pay for my newbieness.
I shot this one at f/4 and exposed it for 10 minutes at ISO 200. Is there anything I should have done differently to achieve better results?
not really anything else i can think of. Some people do short (around 2 minute) exposures. that way you dont get noise build-up from sensor heat. you just merge all the images in photoshop or you can use a dedicated stacking program like registax , but its more complicated to use than PS.
Looks oversharpened and perhaps a bit compressed.
The pic is really interesting otherwise.
It looks as if you had a light source shining from your bottom left...it could have been faint and there the whole time, or perhaps bright and brief, lasting only a second or so. Either way, It's illuminated the trees strangely and given a diffuse orange/red glow to other trees close by. I think the pic would be far better with no light source, just the silhouette and smeared stars.
As to the noise - could you post the pic before you ninja'd it? Would love to see the trees in the original.
GOod job though
The light source is actually a lame attempt by me to lightpaint the trees with a pocket flashlight. I'm not entirely sure why the light doesn't show equally distributed, though. I agree with you, it would have probably looked better without the light painting.
Here's the image before the noise reduction:
Neat! Do you just do a long exposure for that to happen?
Yes, and the earth rotating did the rest
I like the original image before the noise reduction. It might have worked better if more of the trees in front were painted in light. BTW, the stars look great.
That was the intention, but I guess the other trees just refused to absorb the light. I might do it again this week with a stronger flashlight and hopefully the results will be better. Stay tuned...
Sweet. I'm going to have to try that sometime
