Default In DPP RAW thumbnails appear sharp and JPG are soft. What is that about?

Does DPP apply some kind of sharpening to the RAW images when making the thumbnails?

Also have not found any difference when applying sharpening from the DPP tool. 0 or 500, same image.

Fastfwd - My understanding is that DPP does not really display the RAW file, what it displays is a JPG file that is embedded in the RAW file. Perhaps it looks sharper than the full size JPG because of the size. Smaller will look sharper. Hope this helps

I get a massive difference in DPP between no sharpening and the 500 full monty. It goes from soft to so hard my eyes bleed from looking at the sharpened noise. Not sure why yours would not.

As I understand it, the RAW thumbnails are in fact very low res Jpegs created in camera from the RAW data, and have camera preset preferences applied, with maybe an amount of sharpening applied by default, although I cannot confirm that. The full RAW file will have no sharpening applied, although if you choose to use one of DPP's presets, then various tweaks are applied automatically, including sharpening.

The basic data as captured by the sensor will be a touch soft. Allegedly caused by the anti-aliassing filter covering the sensor, or so I've read. So some sharpening is required just to recover the image to it's natural sharpness. This is normally referred to as capture sharpening and is not to be confused with any subsequent sharpening in post processing. Canon have offered suggestions on what amount is required in the past.

The thumbnails won't change much, the image will.
Not important IMO, since you judge sharpening at 100%. Otherwise resizing for screen will cause inaccurate previewing anyway.

DPP uses what you set in camera as default. I generally find that a setting of "3" in the Raw tab is enough. "500" in the RGB tab makes my eyes bleed.

Two screenshots, not color managed, so the color is off.

Sharpening off:

Actually, DPP uses the embedded jpg at first but as soon as you start pushing the sliders around it redraws the thumbnail just as it redraws the full-sized Edit or Edit Image window. However if you save your edits it will not save an edited thumbnail unless you select 'Add thumbnail to image and save' from the File menu.

Is there a difference in one slider over the other?

The numbers Also, the Raw tab is only available when you edit a CR2.
Effect is the same and additive. Not sure if amount is the same for both sliders if set to max.

Okay, that's what I had figured. I suppose that there's just a measure of redundancy for RAW files...
