DPP

[Janice]

In Canons Digital Photo Professional, there is a tab for processing RAW files and a tab for processing rgb files.

In a Canon video tutorial I saw, she said you can either process RAWS in the RAW tab or srgb.. but jpgs etc have to be done under the srgb tab.

So if I sharpen under the RAW tab I dont see much difference with the slider full up, but if i go under the srgb tab i can sharpen more.

Is this the wrong thing to be doing with a RAW file and why are we able to process it under either tab.

Id like to use DPP but have never got to grips with that part of it.

The RAW sharpening does look to be less aggressive than the RGB tab, but you need to remember it's not either or, these are added together. If you add sharpen in RAW and the in RGB your adding more to and more sharpness to the image.

I would think they are just different in the algorithms use to produce the sharpening, and cant' see why you should not use either or both. Canon does recommend viewing at 100% when adding sharpening.

Thanks Mark thats what I thought.. but whey are there the same sliders in both tabs, saturation, exposure, contrast etc etc.?


The woman on the tutorial vid definitely says you can use either for RAW files so what would determind your choice?

I must admit that I normally just have the RAW sharpening set at 4 and then sharpen using RGB, what I have noticed is that with the RAW sharpen there looks to be more effect 1 to 5 than 5 to 10

The same with Saturation, the RAW tab just does not seem as aggressive, but the BIG benefit of using the RGB tab is you can see the histogram change on the fly.

There are the same slides in both tab, so you can do the adjustments to a jpeg image. If you shot jpegs the RAW tab will be greyed out.

I've noticed the same thing Janice, and I was wondering this too. The sharpness slider on the raw tab seems to do much less than the one on the RGB tab. I don't really bother with the RAW tab any more, other than to occasionally adjust the exposure if needed, or change the white balance.

I used to use the sliders on the raw tab, but now I head straight for the RGB tab and tweak the curves on the histogram, and add a little sharpness and saturation. I find it works rather well...

Again as above, leave the RAW sharpener at 3 (think this is default for my 40D) the sharpen away as required in the sRGB tab.

I find that the better the lens I use the less sharpening I require (surprise surprise) but max is usually 150.
