Thanks for your help Stephen I was beginning to think I would have to have +1 set in the camera permanently and ignore the in camera Histogram, I wouldn't have been able to accurately chimp anymore LOL!

:D To be honest Christine those defaults can be a pain sometimes. I have just done a load of shots this morning, all in Raw with different exposures to compensate for light and shadow areas. When you look at the thumbnails in Bridge they all look to have the same exposure, cos ACR has applied those defaults. Sometimes wonder why I bother to give compensation LOL

Glad it was not the new camera :)

Before 1 bought my 20D I remembe reading someting about a tendency to slightly underexpose. I find that it underexposes typically by ~1/3 stop. It look like something Canon have built in to try and help us avoid blown highlights. I find the "blinking" pixels wanring very useful and, except in contrastty situations dial in + 1/3 exposure compensation.

As far as the ACR default setting go I never use them - most of us wouldn't use full auto on our camera so why give up control when you get the image into your software :D I find the best way of judging the exposure for the highlights & shaddows is to hold down the Alt key and then when you click & drag the relevant slider it will show the blown/blocked up pixels & even which RBG channel. I can recommend "Real World Camera RAW" by Bruce Frazer as a good book for getting the best out of your RAW images

Thanks everyone,
I am glad its only a software fault and not the camera but I will miss the ease of doing my workflow in capture one. I can now chimp to my hearts content.:D
