pushing shadows with the 5D MK3 vs. D800

May 2, 2012 3:10 AM

maybe some of you have read the fredmiranda article:


and be suprised how much better the D800 is when pushing shadows.

the D800 produces much cleaner images then the 5D MK3 when the shadows are pushed (the D800 shadow areas look some magnitude better in these examples).


now some suggest part of it is because of an "issue" with lightroom:



maybe some at adobe can have a look at it and give us some infos.



"ACR does not do a good job with Canon RAW files. This is primarily because they don't use optimal coefficient for individual color channels during demosaic. This causes the unusually high color noise in the output. The grain is also too large and intrusive in subsequent processing.

The FPN comes from the sensor itself however its amplitude is exaggerated by ACR kernel. Here is an examples....


i do have some issues with the grain from LR myself (canon 5D MK2, 50D, 550D).

not color noise so much (i mostly shoot at iso 100-400) but i often think the grain is to big.
DPP looks different and often more pleasing to my eye.... unfortunately DPP lacks in workflow.

    I use DPP for raw conversion of my images taken with Canon camera/lens. I use Lightroom starting after the conversion.  DPP is much better at raw conversion than it used to be.


    I do support your hope that LR conversion be improved.

    I cannot see nothing wrong with Lightroom's conversion. DPP just wiped out the noise. So can do Lightroom if pushed further.

    Both. FM and Canon rumours too.

    There is only one problem in all this comparisons.

    When noise reduction is set to zero in LR - there is no noise reduction at all, but DPP applies noise reduction even at zero setting - you can not turn it off completely.


    Speaking about cameras: D800 has better shadow performance at low ISO (cleaner shadows), 5DMkIII has better low light performance (lower noise at high ISO).

    And camera manufacturers always have to choose, they just can't give you both.
