Just to add to Ricks excellent tute, Using CS3 if you hold the alt key while adjusting the black/white sliders your photo will go either black or white and you can see the detail beginning to appear as you move the sliders.....cool

I just tried this and I'm amazed. You can see exactly when you are starting to blow the highlights. Great tip.

Couldn't find an answer to this one in the thread, so forgive me if someone has already answered this, but...
Doing the RAW work (in my case in Canon DPP) obviously alters the histogram when one comes to look at it in the RGB. What are the advantages/disadvantages of manipulating the images in the two different ways?
Any info appreciated..

Any alteration to your photo is going to adjust the histogram. I am not sure what you mean by the two different ways?

thanks for reply..

I may have misunderstood something here as I think(???) the histogram I'm seeing in the DPP raw tab might actually be a luminance histogram, not a levels one. I guess (?) this would make sense as this histogram can be used to manipulate over/underexposure by shifting the whole curve (+/- 2 EVs), not sliding the dark or light levels as in your tute (which I incidentally found very useful).

I'm not explaining this very well, I clearly don't understand it well enough yet.

Thanks
