5DIII pattern noise.

I do not want to start a fight but I have always thought my shadows we rubbish, lets say I need to expose for a waterfall and therefore get dark shads. I should take 3 exposures and blend but that is not always appropriate. This to say with an increase of maybe 1.5 stops in an image with dark but not quite clipped shadows should I expect pattern noise?
I now ask as a professional photographer friend of mine has looked at one particular image and tells me he has used a few of his clients 5DIII files and never seen pattern noise as bad as on mine?

Which starts you thinking.... bad thoughts...

Your pics look good.

Any particular pic?

you will always get pattern noise in the shadows - nothing that can be done about it.

Your shots are lovely btw.

Thanks. Once I am home I will add a picture.

What bothers me is a very respected friend, and pro, had a guy on a workshop with a 5DIII who did not have similar pattern noise. It is better than my old 5DII but can it be that some bodies are worse than others?

yes.

1.5 stops is a lot to ask.

are you familiar with the idea of ETTR (expose to the right)?

I won't be surprised. Just like lenses vary from copy to copy.

However, when I look at your pics, I wouldn't say you have a bad copy 5D.

you can sell the Canon and get a different camera.

I am thinking about it, seriously, that sensor with a T&S lens = sharp, no diffraction and nice huge files for printing....

=he's gone;16593482]yes.

Don't get me started, normally i shoot as far as I can but faced with bright (waterfall) and shadows one either has to shoot 3 exposures or compromise (if the missus is behind me looking at her watch for example).

To be honest i do not think 1.5 stops is too much now, look at the sony sensors, yes age old moan since the D800 arrived but still stands.

Anyway i am stuck with it for now or until I have enough for an A7r...

Have you seen this other togs pictures? Was he taking the same sort of images you are so it was a valid comparison. Did your friend see all this togs work in order to make a valid comparison or did he just see a few of the togs best pieces. Very hard to compare via hearsay. You would really need to post images taken in similar situations to do any sort of comparison.

Well I do not have his images he is in the UK. I guess for now I wil be happy knowing everyone except has that problem kind of keeps me happy....

even Olympus MFT doesn't have that pattern problem like canon.

There is deep shadow noise if you really look for it. 1DX is a lot better if you can spend that money for waterfall shots

Expose to the right and clean in lightroom. Normally that does the trick, and worked a treat just as well with 1DSII

just...wow, i read somewhere, the best sensor is in the A7/7R...is that a testament?

Serious photography leave the wife/gf at home unless she is into it.
