ISO 5000 SD1m SDQ-H

[Roger]

Greetings

Here a few more high ISO just for fun





















It's been very hot here and even with water my plants a taking a beating

Hey Roger, are these OOC jpegs or what? It seems that the latest versions of SPP do a pretty good job on high-ISO raw files from Quattro cameras these days. I haven't tried really high-ISO shots, but I did try some medium ISO shots, and it went pretty well. I guess I should do a comparison between what I can get with my SD Quattro H files fom SPP and some other program, using exported 16 bit TIFF files and the OOC jpegs, just as an interesting blog post for SigmaPhotoPro.com. I could call it "Processing High ISO Files With SPP."

Do you use any special denoisers, like Neat Image or a special plug-in for Photoshop or Lightroom?

The colors from the S/D qh look nicer.

"S/D qh" Ted?!? lol

Hi, Scott, "if you can't beat 'em, join 'em!", eh?

Notice also the delightful vagueness of "look nicer" ...

... time to shoot the s/d-9 at some shrubbery and rolling hills ... ;-)

I don't find either of them particularly useful in color, but Merrill works better for high-ISO monochrome since it doesn't have (variable) AFE banding.

Yes I noticed it too. Almost like scan lines on a CRT!

The SD1 does not have this.

Just to put it into perspective. I am not saying that the sd Quattro can't take very beautiful pictures, even at higher ISO. But a bit of reality check: what a FF modern Bayer can do with high ISO leaves the Foveon in the rain. And I say it again, I love the image quality from the Foveon (especially the 1:1:1) at lower ISO. I will run for the 20MP FF Foveon whenever it may hit the market.

In both cases, I set ISO to 5000 and let the camera decicde upon aperture and shutter speed. Both imported into SPP6.8 and processed wth all settings in the zero position. Also NR was set to zero.

The lens on the sd Quattro H was the Sigma 24-105 set to 24mm and on the fp I used the Leica 24-90 set to about 35 to match the field of view. I was to lazy to exchange the lenses but I think it has no influence on the noise performance.

I show them in full resolution (sorry to the guys with slow data rates). You definitely have to view it in full resolution to appreciate the difference.

Here are 1:1 crops to make it easier for the ones who don't like to download the big images.

Why did you expose the SD Quattro H image 1 stop less? I think there would still be a big difference, but maybe no so alarmingly bad, if you had exposed the photos the same amount. In fact, why not just expose both at f5.6 for the same amount of time at the same ISO setting?

All that said, I'm amazed how clean the fp image looks with no noise reduction at ISO 5000. I wonder how the fp-L would fare in comparison.

"In both cases, I set ISO to 5000 and let the camera decide upon aperture and shutter speed."

Frank did not set the exposure, the cameras did, via auto exposure.

[re-edit] For some reason, the metering was 1EV different.

I think there would still be a big difference, but maybe no so alarmingly bad, if you had exposed the photos the same amount. In fact, why not just expose both at [the same f-number] for the same amount of time at the same ISO setting?

You are right. As I said, I let the cameras decide.

Hello Scott

Hey Roger, are these OOC jpegs or what? I

Theses a Raw then saved in JPEG using SPP only. No Noise Reduction applied

t seems that the latest versions of SPP do a pretty good job on high-ISO raw files from Quattro cameras these days.

Yes it does

I haven't tried really high-ISO shots, but I did try some medium ISO shots, and it went pretty well. I guess I should do a comparison between what I can get with my SD Quattro H files fom SPP and some other program, using exported 16 bit TIFF files and the OOC jpegs, just as an interesting blog post for SigmaPhotoPro.com.

Good idea

I could call it "Processing High ISO Files With SPP."

Excellent

No I do not. PhotoScape X reads my XF3 files up to the SD1 but I like SPP better although both programs are free.

Thanks

They seem to be.

The FP-L has more MP but also has a AA filter where the FP has less MP but does not have an AA filter. To me the FP is cleaner, sharper.

Although for me I'll take the Foveon at a lower ISO over a Bayer sensor. I can get excellent results at 400 to 1600 so I'm good. There are a lot of Bayer sensor cameras out there but only one Foveon.
