MC will do a default DCRaw conversion. This will probably not match the conversion you'll do. I would pull only finished images into MC.
Reading between the lines, rightly or wrongly, I took this to mean that there wouldn't be a great deal of development time assigned to this.
Do Bridge and the Canon software read each others edits?
I recently bought a Nikon D5000 and shoot exclusively in RAW.
It was with a lot of anticipation that I pointed MC at my first ever RAW photos. The let down was huge.
I say that, because I knew absolutely nothing about RAW files other than that they represent the image data as captured by the sensor. I was kind of hoping MC would 'just work' and I wouldn't need to climb aboard another learning curve.
I found that MC was very very slow in dealing with my RAW files, so I went for a trip into options and found settings for a RAW cache, which I set, but MC appeared not to be using; either that, or something else was causing the slow down.
When an image was eventually displayed, it looked pants and there was an ugly purple band down the right hand edge.
XnView faired no better in this regard.
I needed help,
so I asked, and received some helpful replies.
I posted some of the issues I had experienced in another thread,
"Nikon NEF: Kudos and Feature Request", where DarkPenguin explained that there were no industry standards for processing RAW files....
That is a pretty new camera, right? Might not be supported fully (or correctly) by the version of DCRaw included with MC. I wouldn't pull raw files into MC unless you're using MC to tag them. They just will not look the same in MC as they will in whatever RAW software you're using. This is a limitation of RAW. There is no standard for applying RAW edits. MC will do a default DCRaw conversion. This will probably not match the conversion you'll do. I would pull only finished images into MC.
edit: It should be mentioned that another way of working with RAWs in MC is to do the conversions in another application. Then have MC try to auto stack the files. (Test a few to see if this works.) Then you should have the RAW file available and its preferred incarnation as the stack top.
As an aside I would be really happy if this $%@#$ reflux would settle down so I could go to #%$!#@$ sleep.
So, I grabbed a copy of the Lightroom 3 beta and began playing.
I used a temp jpg file and tagged it with every keyword in my MC library and imported it into Lightroom.
Having tried this for a while, I have decided that for me, keeping the RAW files in a program such as Lightroom is working well.
I export jpg files with keywords applied, from Lightroom to a folder that MC watches, and from there, MC takes over and the exported images can be correctly filed away as per the tags.
I've decided not to use the stacks suggestion as it feels as if it's adding a layer of complexity that I don't really need.
Lightroom looks after the RAW files, and MC looks after the jpgs. Simples!
I have begun lobbying family members to chip together and get me a Lightroom license for my upcoming birthday. Wish me luck
