HDR Problem- Question...

[pointerDixie214]

so tonight I took some night shots of my car for HDR... here is the outcome. WTH is all the blue "noise" in the photo? It's not in any of the originals.

I shot these at ISO 800, I am wondering if I shouldn't go reshoot at ISO 200

I did a screen shot so you could see my setting in Photomatix. I also blew up a portion of the photo and put it in the top right. I did three yesterday at ISO 100 and didn't have this problem, so I am wondering if its noise. But the originals don't look too noisy...

Nope, it got deleted. I blended 4-5 shots though and I would guess (90%) sure it was the noise that caused it. I am going to try again tonight at ISO100 and see if the problem persists...

Since this look like a dark image to begin with, you should use a noise reducing software before processing to HDR, that might help. But without the original files you just have to live with this :D

you should use a noise reducing software before processing to HDR,

agree, +1

Thanks. I will reshoot again tonight or tomorrow...

Doesn't PM 3.1 have a noise reduction feature built in? Are you shooting RAW? You may be better off converting the RAWs to TIFs and then combining (i.e., use a better RAW converter and apply noise reduction rather than PM's).

I'd have to say your settings are all wrong. If there was no noise in the originals, there should not be any in the HDR. All you smoothing sliders are down at the low end.
