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:

ScreenShot-572

ScreenShot-573

ScreenShot-574

ScreenShot-575

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.

ScreenShot-577

    The only one I can see the difference is on the 2nd image.

    LR is purple. DPP is blue.

    which one is the actual?

    then try LR save to JPG and DPP save to JPG, what’s the outcome?

    Yup you got it right. If you notice all the blue colours in all 4 photos, they are different from DPP and LR. Notice the blue spotlight in the 3rd photo (a single dot, the one beside the ‘white halo’ on top of the girl in white). in LR it’s purple at the edges.

    I’ll try that tomorrow. will try converting to DNG as well to see the difference..

    now i see carefully la. 1st pic can see the difference (damn, after 1 soda even my super-duper-hyper-CMOS (SDHC) also improved!).

    3rd pic very little difference, but like what you said – most noticable is that blue light near the head of the girl in white.

    4th pic yes, the blue and purple, lower portion of the artsy thing.

    *btw, next time put images same size leh.

    *and it’s the same image size. =p
