Canon EOS 30D RAW, Adobe Photoshop Lightroom, Canon Digital Photo Professional
Written on June 8, 2009 by CincauHangus
I’m having this problems with my 30D’s RAW files when I import them into Lightroom for editing. Then I had the opportunity to know some Lightroom gurus at ShootFest yesterday and I asked a few questions regarding them.
Firstly, was the oversaturated colours I get after importing. An example would be like a concert stage is being lit up with a light purple spotlight (seen on the naked eye, it was a very light purple). Upon importing, the light purple became solid purple, making the whole photo unusable unless you desaturate that particular colour, which in the end I made it b/w.
Someone at Shootfest suggested that the RAW file details were stripped off upon import and thus losing the some photo data. Markleo also suggested to use Canon’s RAW editor (Canon Digital Photo Professional) to edit before hand, so raw details could be preserved. I tried it out and I could see a difference between LR and DPP. Following are some comparison of LR and DPP:
As you can see, LR saturates the photo making the colours even more darker. (all photos were not edited) *SOME* became over over over saturated till no matter how I try to desaturate them, it’s still unrecoverable. 
Also another problem (may be related) is that upon LR export, *SOME* photos turn out to be desaturated when compared to the same photo in LR. If it’s related, then it makes some sense, but it gives me another problem. I cannot judge the right saturation for all my photos in LR.
So how now?
I found a suggestion on a Flickr regarding the use of Adobe DNG to preserve the RAW details (somewhere in the comments). I’ve yet to try this out, but would like to know whether there are any photographers out there that have tried DNG before.+
Update:
Here’s a sample photo generated from DPP v3.5, LR v2.2 and ACDSee v2.5 as well as a jpg extracted from the RAW file. All the images generated were not edited. Notice the difference of the purple spotlight.
