Another problem of my M9 , last time my jogging wheel not work until now , this time I shot at day with low ISO during shot I also not enlarge picture to see I did a good focus. when I back home and saw pictures on my computer all pictures have a noise very much the skin tone, sky, subject have its very much. What does it come. Please suggest and comment.

The EXIF data of your image shows ISO 640???

 

Was it on auto ISO, and did you expose manual? In that case if underexposed according to the camera it ramps up the ISO.

Yes, that’s clearly not ISO 80 or 160, but rather ISO 640. The saturation looks like it was cranked up to the max, resulting in unnatural looking colours but also in more chroma noise than necessary.

It looks like the camera exposed for the sky, placing all the skin tones way down the scale. All the skin is well below zone V or VI. So the noise in the skin is because that part of the image is down in the dark parts of the scale.

 

It also looks like the chroma in the parachute also contains blooming or is adjacent to areas of blooming.

 

To me, the problem is that the range of brightnesses is too great for the picture. If you were facing the subjects -- with the sun behind you -- the results would be much more to your liking.

Check the ISO - if it was really shot at ISO 640 there is not much else to say - it can't be used as an example of "low-ISO" noise.

 

If you have a real low-ISO shot to share: was it dng or jpeg originally?

 

Also bear in mind that if you shoot into a bright sky as in this shot with automatic metering, you will likely underexpose 2 stops of so (as mentioned by all the previous posters). So even if the camera was set to ISO 160, by the time you have brightened the picture 2 stops in post-processing, you will have an effective ISO 640 shot - with ISO 640 noise.

If I were guessing I'd say that it was shot as a Jpeg with the saturation turned up and that auto ISO has decided to use ISO 640.

And the camera was probably left to AE - underexposing the important parts of the image. Was it in Snapshot mode with AutoIso turned on?

I'd like to add that except for heavy oversaturation, it's a nice photograph.

according to the EXIF information

more importantly this was taken at ISO 640 and 1/4000 second, the upper limit for the M9, so almost certainly Auto ISO was used

the EXIF lists the lens focal length as 18 mm

this appears to have been taken using jpg capture & the camera settings were listed as high saturation and hard sharpening, all of which were a perfect storm for funky results
