Weird DPP behaviour, Raw images get softer as they open fully.

Raw images from a 1D4 and 5D3 opened at 100% take a few seconds to "develop" in DPP 3.11.26 (Mac) they begin sharp and as they develop further they soften considerably. Even when I set Viewing and Saving Images in preferences to "High Speed" it still softens as DPP completes opening the photo. My jpg settings which govern how the images is presented are "Standard" with sharpness at 4 instead of the default 3.

LR 4.1 does exactly the opposite, its initial opening is soft and as it develops the image gets sharper. Default settings.

Anybody else notice this softening?

What version of DPP are you using?

They do not develop. :) [EDIT: They do, in a way, but this is not like watching a print developing in a darkroom.] The software needs some time to render the image. It starts with a pixelated one (DPP) or a blurry one (LR) so that you can still see something, while is computing the preview. Another option would be to display a black frame or just to hang for a second or two, and you would not like it.

I don't think I get your point. Why would the initial image which appears to be the same resolution as the final rendering, be sharper than than the fully rendered image?

On my computer, it is not sharper, it is pixelized (consists of blocks).
 
Is it possible the preview is some sort of sharpened/tone curve adjusted embedded jpg rather than a pixelated photo/black screen?
 
You might be seeing the image update after the software finishes the noise reduction computation. Try setting the noise reduction to zero.

That sound reasonable, but starts soft and within seconds is much sharper than the DPP fully rendered 100% image. In the end they should both fully open with roughly with the same sharpness.

I set default NR at zero on both DPP and LR

It could be that DPP is using a full size embedded JPEG for the preview while rendering. Canon JPEGS use quite strong sharpening and steep contrast curves, which both increase impression of detail. I suppose DPP uses lower sharpening & contrast defaults?

In LR the standard is to have a medium sized (I.e. smaller than original) JPEG which, in 100% view looks soft. When LR is finishing rendering the RAW file, the resulting preview certainly is sharper.

Hope that helps...

I can duplicate your description by setting the NR in DPP. Then when you open the image it displays pixelated for a moment, then sharp, then the NR takes effect and it softens a little.

Even if you have NR default off in the camera, check what DPP is doing.
 
The phenomonen I have described appears to be a Mac only one. The latest version of DPP on my Windows 7 laptop opens as many have suggested (pixilated) then completes rendering and is very sharp. Setting on the Mac DPP and windows DPP are identical.

It's interesting that the MAC DPP initial opening is sharp and not pixilated which morphs into a softened version of the image. Even high sharpening after its fully open is not as sharp as the default opening on either Windows DPP or LR 4.1 on the MAC.

Go figure???

Some of the rendering is done by the GPU, so it may be hardware (and driver) thing as well.
