Hi All

I own the Canon 50D camera.

When using the superb Canon DPP software and saving the edited image as a 24bit JPG (full quality) they appear soft...

When I compare the saved jpg against the edited image in DPP, there is a stark difference.

Is this because I am looking at a RAW/CR2 file in the edit window which holds more data bits in the image?

I have tried all the image viewing software under the sun and the images are still soft. Although, when seen in DPPViewer Module they look a little bit sharper.

I have tried several professional image editing packages and DPP wins hands down for me as I assume the software is tweaked to work well with the Canon RAW file hence the better quality? But the exported jpg files are a dissapointment. Why can't we use RAW or TIFF files in web pages LOL :-)

Hi dfk,

Have you tried adjusting the Sharpness setting under the Tool Palette RGB tab? This is a separate adjustment to the one found under the RAW tab. Unfortunately I haven't spent too much time using these adjustments as I prefer to let DPP do the RAW conversion and vignetting and lens corrections and then work the exported TIFFs using Photoshop but if you want to adjust the sharpness of JPEGs I think the RGB tab is where you need to be.

Bob.

Can you upload these soft images somewhere for us to see? A picture is worth a thousand words, as they say.

Are you looking at them at 100%? Otherwise you are just comparing downscaling ;)

When I save 16 bit PNG from DPPP it looks great nearly as good as the RAW file but JPG's are still a dissapointment.

Can the downscaling make the image look good at 100% but soft at screen size?

Indeed.

Say, your image is 4000x3000, but your screen is 1280x1024. If you look at the image, the system will have to drop pixels. Some systems are better than others at this, but the essence remains that you can't judge sharpness in a picture unless you are looking at it at 100% :)
