Hi All

Just looking over my 40D and also looking at my monitor calibration settings and wondered what settings i should have both on?

My 40D has the Option for sRGB or Adobe......What does everyone else use on here and is one better than the other?

Should i also set my Monitor to Adobe RGB????

Your monitor is unlikely to have a wide enough colour gamut to support AdobeRGB so it will end up 'clipping' the extremeties of the colour range, ending up with muddy or unsaturated looking images. In other words, if you are intending them to be on the computer, stick with sRGB. Only put them into AdobeRGB if you are sending them off to a professional printers that support AdobeRGB. :)
 
Your monitor is probably made to be nearest to sRGB as it can, so stick to sRGB or better, calibrate your monitor !

For the pictures, if you shoot RAW it doesn't matter. If you shoot JPEGs it might help a little to squeeze a bit more gamut in, however you will have to covert them to sRGB again for web and sending to your lab for printing, so all in all it's not very useful.

Converting gamut is never free, and in fact it can be quite clostly on aliasing artifacts, unless you use dithering but that's also quite destructive.
 
What software do you use for processing? Lightroom works in sRGB exclusively so it make managing eveything easier.

Personally I use sRGB throughou even though AdobeRGB has a wider Gamut, my monitor will struggle with it.
 
I stick to sRGB since most monitors don't make use of Adobe and I've had the odd problem with getting photos printed when I have used Adobe as well (my own fault each time!). To be honest, the difference in quality really isn't that noticeable unless you are a pro or really picky so better to stick with what the masses use and save yourself any headaches.

Isn't it a bit odd that LR works in sRGB and yet you can chose the colour profile it exports files with. I've only just noticed this. It's not really a problem as I work exclusively in sRGB for screen anyway - anything that goes to print goes CMYK.

I tought LR was using Prophoto, which is the sensible thing to do as it manipulate the RAW file and needs the wider gamut.
 
Sort of.

The Lightroom edit space uses the coordinates of the ProPhoto RGB space for editing, but uses a gamma of 1 rather than 1.8. The viewing space is exactly the same, apart from it uses the sRGB tone response curve.

You're right in what you say about ProPhoto though. It's so large that it can easily cover any colour that a digital camera could capture.

Is this the answer to the above question?

I think I may have had a missunderstanding of the way lightroom works here... Re-reading it seems that LR automatically manages the colour profile for an image with attached profile, an Image with no profile is treated as sRGB (which may be where my missunderstanding came in). The colour workspace is ProPhoto RGB with a gamma of 1.0 (which makes it not proPhoto I suppose).

Is it correct to say that RAW images are Viewed onscreen as sRGB (as the they have no colour profile) and worked on in LR RGB. Printing will then transpose these colour spaces appropriately to the selected output workspace.
