Default Requesting assistance on this one

I got a horizon unlevel rejection for this photo. Which way should I go?

From my stand point, I leveled it by the station platform in the distance.

Not to be a naysayer, but the grain/noise in the lower left hand corner may get you dinged no matter what rotation you give it. Can you clean that up?

I agree with Charles, the noise is really noticeable...almost a distraction.

I'll rotate it along with cleaning up the noise and put it back in the queue back.

Thanks guys!

Hahaha, awesome.

He forgot to photoshop the moon into the corner. Once he adds the missing piece, he'll be good to go.

I think that if he converted it to B&W and increased the contrast a tad that the noise would be less noticeable or at least more "acceptable" as a lot of people seem to not mind noise/grain when its B&W.

You broke it, how do you get the noise at 100 ISO to look like final fantasy?

Not trying to defend chase here but cameras do build up noise during long exposures. Though his was only 20 seconds. If he had happened to do several before this shot that may be an explanation.


That or somebody used the shadow/highlight tool quite a bit, curves, or shot RAW and used the raw processor to bring up the exposure on the end of the car. Or a combination of all 3.

I never knew that. How long do you need to let the camera rest between exposures to get rid of that?

Never experienced noise build up before, and considering the amount of long exposures I shoot, I would have.

The number one culprit that causes noise in long exposure shots is underexposing, and having to boost post process.

Or using too high ISO

HDR programs will also add noise in weird places and in the shadows.

I've got several night shots that were taken using ISO 1600. If you don't fiddle with the exposure, they are quite fine for RP size shots with some slight noise removal.

The key is nailing the exposure. Higher ISO usage is a distant second place in my book.

Question: is this related to the function on my 20D where one takes a long exposure and then the camera closes the shutter and takes a second long exposure of sorts, of darkness, and then uses information about individual pixels to adjust the main exposure? (Obviously I am not an experienced night shooter!)
