Re: PESO - (and a question) - Love on the Dancefloor

Frank, I reckon that sometimes the beauty of the captured moment gets 
overshadowed by technical nitpicking.


I should tell you that if you did not write all the story quoted below 
and just shown a picture, I wouldn't have thought about this at all.


It is simply very good picture and frankly, I could care less about the 
amount of noise reduction you applied or specifics of b/w conversion 
that you used.


Sorry, if this is the answer that you did not expect.

I'm fairly certain it will happen in Foveon sensors as well, any digital 
recording device with a grid pattern in fact.  The best way to avoid it 
is to not over expose especially at high ISO values.

Is banding inherent to the Bayer pattern sensors; something to do with 
the algorithm necessary to fill in the blanks?


I wonder if the Foveon sensors Sigma uses have the same problem with 
banding at high ISOs?

My first thought is: ISO 3200, slightly underexposed (perhaps)... when  
you jack the levels up it brings out the subtle noise and such which  
is present on the sensor when you push it to those extremes.


I had occasional noise issues like that with the DS - and I seem to  
recall that there was an issue with the DS (can't speak for the D)  
especially when shooting in fast multi-frame mode and in high ISO  
settings where that horizontal banding would pop up from time to time.


I doubt it's the card or the computer - it's probably whatever came  
from your sensor (unfortunately).


It's a fun picture, in a grainy, grotty, peek-in-the-dark sort of  
way!  The noise doesn't bother me, and actually I think it helps the  
image (except for that horizontal stripy stuff).

Hey, Marnie,

Thanks for the comment.  You likely don't know this because you've
been away for a while, but my computer's been down for a while (needs
a new hard drive and I can't afford a new one right now).  My computer
has Photoshop, but neither my work computer nor my partner's computer
have that, so I've been relegated to processing my pix at work with FS
Image Viewer.  It really doesn't allow much to be done - certainly no
noise reduction.

In PS I'd have certainly been able to reduce the noise a fair bit -
and the resulting loss of detail wouldn't have hurt the photo at all.
So once I get my 'puter up and running and re-loaded with PS, I'll
have this thing rendered so it looks much better.  I think I have the
seed of a decent photo here, but clearly more needs to be done.

As much as anything else I posted it to get opinions as to the
horizontal striping on this, to see if it's something I can avoid in
the future (it appears not).

As for ISO 200 - I think it would have been a bit slow for that dark
dance floor!  ;-)

cheers,
frank

It's a gorgeous shot in spite of the noise. Grain and noise don't

I think the line is just a function of all the noise. It was probably

They appear to be, in part, JPEG artifacts that come and go due to  
aliasing at different on-screen scalings. You can generally minimize  
these sorts of artifacts by using less compression when outputting  
your JPEG files.


They also appear in underexposed digital captures due to how the  
sensor records edge conditions near the noise floor of its operation.  
Underexposure is always to be avoided with digital capture in order to  
obtain the best quality. If I'm working at the noise floor limits of  
the sensor, I add some randomized noise to the image and then soften  
it to minimize/eliminate these kinds of regular patterning.

It's a gorgeous shot in spite of the noise. Grain and noise don't  bother 
me, but I would clone the line out.
I think the line is just a function of all the noise. It was probably  a 
single color before conversion.

Okay, but seriously, I'm happy with this.  Had I processed it in PS
I'd have used plenty of noise reduction which would have helped a lot,
but you can only look at and comment on what's on your screen right
now, I understand that.  I hope you think it's a cool photo, too.  Let
me know.

I do have a question, though.  There appear to be horizontal lines
going across this image, the most obvious one going through the
female's upper eye.  What are these?  I've not noticed them on other
images.  I don't know if it's a problem with the camera, the card or
the computer.  Any ideas?

thanks,
frank

Banding can be a problem with all DSLRs, it usually shows up at higher 
ISOs.  (What a higher ISO is depends on the sensor chip).

 No idea about the mysterious lines, but I love the photo!
 I wouldn't worry about noise reduction; the noise adds to this shot, IMO.
 Sort of a Bob Capa covers the rave scene feel to it  :) 


Is banding inherent to the Bayer pattern sensors; something to do with 
the algorithm necessary to fill in the blanks?


I wonder if the Foveon sensors Sigma uses have the same problem with 
banding at high ISOs?

  Captures the mood, but  pretty noisy. I suspect those are due to   
 high ISO.

 Marnie aka Doe  :-)  I tend to keep  my ISO set at 200, most of the  
 time. It
 covers most   bases.


Marnie -

1/13 of a second at ISO 3200 comes out  to... about 1 second at ISO  
200.  I don't think he could have  gotten the shot that way!

Yeah,  I realize in that situation it wasn't possible.

Marnie aka Doe :-) OTOH,  in that kind of situation, if I take a shot, I 
don't expect much  either.
