Hi,

I've just started using DPP just to see what it can do as I normally just use Aperture, and have a quick question for you. I usually just shoot in RAW but noticed a RAW setting in DPP that allows you to change the picture setting to lansdscape, portrait etc. I leave my picture setting as neutral on the camera, but in DPP if you change it to landscape it adds sharpness and boosts the colour. That's what I don't understand: the on-camera setting of landscape just adds 4 points of sharpness, but on DPP the colour is also boosted even though I can't see any of the other setting sliders change. Does anyone know how DPP is improving the colour as I can't see any settings other than sharpness changing?

If you shoot raw, I think the picture style settings are doing the same thing - regardless of whether you set from camera or use DPP to change them.

Canon also has a 'picture style editor' that may let you see more details.

I'll have to give the Picture Style Editor a go to see if it sheds more light on it. The colour is a little flat when I open up the Neutral image in DPP, but as soon as I select Landscape in the picture styles the colour becomes more saturated as well as the sharpness being added.

The picture styles in DPP and on camera are not in sync. You can adjust the camera files to match the DPP ones, or the DPP ones to match the camera.

If you shoot raw, it does not matter what you set on camera, if you shoot jpeg your stuck with the results of the on camera settings.

Thats interesting.
I always assumed the DPP/Picture style jpeg conversion would be pretty much the same as the in-camera (unless I adjusted something).

Always learning something here ...

Jimmy DPP pictures styles are set up to do lots of different things to you shots other than what the camera is set to do. Don't know why they did it that way. On page 25 of the DPP manual it tells you what each does.

Yes I notice in the manual that the blues and greens will be boosted a little in the Landscape setting. I was just wondering why none of the other sliders moved to show this colour boost. After closer look though I've noticed the red and green 'peeks' in the histogram on the 'RGB' tab do look longer when this puicture style is selected. So I guess it is making changes under the hood.

Canon doesn't reveal much the interior workflow of DPP, but my guess is that the Picture Styles are done in the tone curve / gamma correction stage by applying separate curves to each channel and varying them slightly to emphasize different colors. The additional changes you call for with the sliders would be a later stage.

The standard, portrait and landscape picture styles use a more contrasty tone curve. The landscape mode also boosts the blue and green color channels. The neutral and faithful picture styles use a flatter tone curve with less contrast and less color saturation across color channels.
