5d2 shadow noise and how I eliminate it...
« on: February 04, 2013, 09:53:51 AM »
I have discovered over the years that the best way to get super clean shadows with the 5d2 is to overexpose the image. I have not really tried it much with portraiture but in industrial, landscapes and architecture and interiors it works very well. I am quite surprised how much detail there are still left in what appears to be 'overexposed' highlights and because the shadows are 'overexposed'  they are clean when I 'pull' them in post processing. More images and some thoughts why I think my 5d2 is still good enough for most applications here at..http://www.ivanmuller.co.za/blog-item/expose-right

It certainly can be good enough for a lot of things, and some technique can extend that for sure.
BUt, I got rid of mine tho, as I'd purchased it for landscape when it came out and it was the most disappointing camera I've owned.
Just did some extra test shots before I sold it recently; flat shade target, shot at 1 EV intervals from -5 to +3 as metered.
Histogram peaks line up perfectly on the grid in DPP at those levels.
Then pushed them a little in post using ACR or DPP.  Don't even need to go +2 stops before I saw pattern noise on not only the -5 EV shot, but the -4 and the -3 EV shot would show FPN with as little as +1 EV push!
That, to me, is a camera with severely limited dynamic range if the appearance of any FPN is the criteria.
That was a deal-breaker for me, should have got rid of it long ago.
I did get some great shots with it, but it just didn't work the way I needed/wanted/expected it to.

I'd like to know if other 5d2s fare as poorly with the same kind of test or if mine was just a complete lemon.

6D seems considerably better, not sure if enough to appease me yet.

The "exposure to the right" technique is nothing new. But its always nice to discover these things personally  ;)

Not good enough for landscapes?
Well, I am.
And pushing shadows is always a bad idea.....
Especially in making landscapes we have all the time to fix all adjustments to optimum.

My 2 Eurocents.
1D MKIV, 5DMk III, lot of lenses, flashes etc
Fuji X100s, Sony RX100 III

The problem is that expose to the right , in my experience doesn't always work...My Leica X1 loses highlight details very quickly and my Mamiya Zd has got a lot of leeway in the shadows and it can be pushed without the noise and banding associated with the Canon...my experience so far with the Mamiya is that it it can handle less overexposure than the 5d2 but its not really a problem pushing the shadows...so one has to find out these things for oneself for each camera because they all behave differently.... :)
