hdh Posted March 28, 2018 Share Posted March 28, 2018 I think the image looked at 100% is generally very grainy. There are a few threads with the RX100, about noise and graininess, specially in low light conditions at higher iso and wide open aperture. This could be the case for this image.

spacecadet Posted March 28, 2018 Share Posted March 28, 2018 It has very bad compression artefacts. It's not over-compressed so I'm guessing the reason is uncontrolled noise. I downsize my high-ISO images to the minimum (3250 long side) but I don't think it would have saved this one. Beside noise reduction try switching to RAW if you haven't already.

M.Chapman Posted March 28, 2018 Share Posted March 28, 2018 Looking at the 100% image it looks pretty noisy/mushy to me. Not sure if it's noise or jpg compression artefacts. I note from the EXIF data is says it was shot at 1/80 F/3.5 ISO400. I would expect a better result at ISO400 from Sony RX100. Is this an in camera jpg which appears to have sharpening set to Hard perhaps with too much compression? If so, should get better/cleaner results if you shoot in RAW and process in Lightroom or similar and save as high quality jpg before submitting. 100% crop looks like this.

I have tried to replicate the artifacts with my RX100 and could not get them like in this image. QC is known to be quite strict on smearing and over-sharpening. My guess: it's an out of camera JPG. Or a RAW which has been developed with the exact in-camera settings. (Proprietary raw developers tend to default to that.) wim Link to comment Share on other sites More sharing options...

liverpix Posted April 4, 2018 Author Share Posted April 4, 2018 Thanks for your replies. I normally shoot in jpgs as was this photo, mainly because I tend to take a lot of photos and I never really got my head round RAW. I just had a look at my camera settings. There is a High ISO NR on my RX100; it was set on Normal - I have now changed it to High. Link to comment Share on other sites More sharing options...

The best way to get optimum detail is to shoot RAW. Link to comment Share on other sites More sharing options...
MariaJ Posted April 4, 2018 Share Posted April 4, 2018 I also have the rx100 (mk 1) and I find it there is a lot of noise when I use ISO 400 and up, especially in the dimly lit areas of the image. For passing QC purposes, it may be best to avoid high ISO settings. However it looks to me like there's more than noise in the image. Seems more like jagged artifacts. I'm not sure what step of your processing may have caused them. Did you do much post processing on the jpg image? Link to comment Share on other sites More sharing options...

It's a bit like saying "I ride a bike as I cannot get my head around a steering wheel" as it's fundamental these days. Link to comment Share on other sites More sharing options...
Colin Woods Posted May 10, 2018 Share Posted May 10, 2018 Yes, if you want to avoid these types of problems and get the best from your camera then you have to get into processing your RAW files yourself. There are countless videos and websites on the internet that you can follow, as well as the concentration of skills here on this forum. It seems intimidating at first but its not that bad and you will be astounded by the information you can pull out of the RAW files. You will need to splash the cash a bit as you will need a RAW converter - the big players are Lightroom, DxO (my choice) and Capture 1, with Luminar, Affinity and On1 playing catchup.
