lovelyleica Posted January 7, 2008 Share #1 Posted January 7, 2008 Advertisement (gone after registration) Using mainly Lightroom for organizing and postprocessing digital images I could realize how wrong Lightroom is with red tones. After twickling color hue, saturation and luminance cursors I could get much more realistic results. Here is the comparison snapshot from lightroom. The picture was taken with a WATE, no UV-IR filter, Lens detection M8 option “On” Parameters used in LR to compensate and get right side photo : Color correction: RED Hue / Sat / Lum = +27 / -27 / -48 Camera Calibration (for no IR filter, colorchecker used to calibrate): Red -4 / +20 Green -8 / +6 Blue +6 / +19 Comparison picture between LR and C1 after red correction in LR : If you want to know more about calibration go to my web site + choose "blog" link -> Homepage Link to post Share on other sites More sharing options...
Advertisement Posted January 7, 2008 Posted January 7, 2008 Hi lovelyleica, Take a look here M8 red color rendition in Lightroom is wrong - Here are parameters to correct it. I'm sure you'll find what you were looking for!
jaapv Posted January 7, 2008 Share #2 Posted January 7, 2008 Yes - one of the reasons I don't like Lightroom. But in this shot it seems that the red channel on the lady's jacket is quite overexposed, losing all detail, and that doesn't help. Link to post Share on other sites More sharing options...
ho_co Posted January 7, 2008 Share #3 Posted January 7, 2008 Jean-Luc-- Very nice job; thanks for posting. I think part of the reason for the overexposure Jaap mentions may be the lack of UV/IR-cut filter. In a couple instances where I didn't have the filter, I've found that reds tended to overexpose into the same ugly, vulgar, off-color range using CS2. Good that you took the time to work out the improvements and post them! --HC Link to post Share on other sites More sharing options...
johnbuckley Posted January 8, 2008 Share #4 Posted January 8, 2008 Appreciate this. But since I do use UV/IR filters, as well as Lightroom, will the exposure paramaters listed work equally well? JB Link to post Share on other sites More sharing options...
lovelyleica Posted January 9, 2008 Author Share #5 Posted January 9, 2008 LR is not that much better with IR filtered photos. I added a comparison of a UV-IR filtered photo to my blog here : Farines-Photo Blog Blog Archive M8 DNG Lightroom red color correction Link to post Share on other sites More sharing options...
barjohn Posted January 9, 2008 Share #6 Posted January 9, 2008 Lovelyleica, I just downloaded and tried you C14 like adjustment and it is very good. The best I have seen so far. I really like what it does for skin tones. I highly recommend others give it a try and see if it holds true for a range of photos. I have tried it on aroun 5 photos and really liked the results. I haven't tried your other profiles yet. Link to post Share on other sites More sharing options...
lovelyleica Posted January 9, 2008 Author Share #7 Posted January 9, 2008 Advertisement (gone after registration) Thanks John for your compliments. Color management and getting best color rendition out of LR is not an easy task and it needs quite a hard work to get good results with Leica M8 Raw files (IR or Not). There is lot less discrepencies and problems with Nikon or Canon Raw files for example which "develop" much better in LR. Link to post Share on other sites More sharing options...

In front of the Post Office. Aren't you ?! Link to post Share on other sites More sharing options...
lovelyleica Posted January 9, 2008 Author Share #9 Posted January 9, 2008 Yes you are right, I see you know the place. I have been to Locarno for a day with train from Zurich. Very nice journey through gotthard tunnel with the train making loops inside the mountain. Consequence is you can see a church a few times, each time from a different direction and altitude !

sbelyaev Posted January 10, 2008 Share #10 Posted January 10, 2008 I use IR cut filter and found the same problem. Bright red objects have magenta tint. For example the jacket on this picture is supposed to be bright red (almost like bright blood). Unfortunately Lightroom corrects not only bright red colors but all other colors that have red component (like skin). Pain in the neck, but I can live with it. Welcome, dear visitor!

elopezso Posted January 10, 2008 Share #11 Posted January 10, 2008 Sounds great! As you know, LR and ACR have the same develop engine. How would I load your template onto Adobe Camera Raw (CS3 version)? Thanks, Ed Link to post Share on other sites More sharing options...
fotografr Posted January 10, 2008 Share #12 Posted January 10, 2008 How would I load your template onto Adobe Camera Raw (CS3 version)? Thanks, Ed I'm curious about this, too. It would be kind of a PIA to have to remember to make these adjustments for every batch of photos. Link to post Share on other sites More sharing options...
woodyspedden Posted January 10, 2008 Share #13 Posted January 10, 2008 Brent et al Set up ACR 4.3.1 using these settings. Then save them as a preset using an appropriate name. Now each time you open ACR you can click on this preset without having to remember any of the settings. I think this works correctly Woody Link to post Share on other sites More sharing options...

archi4 Posted January 11, 2008 Share #15 Posted January 11, 2008 I have multiple presets in Lightroom for both my M8 and Olympus DSLR RAW files and have added all the above too. Unfortunately, results are not consistent, nor are they really satisfying. I have reverted to using Capture One Pro or v4 -( Pro for when I want to edit profiles.) Printing from LR is excellent and I import the developed files. Color management is perfect from screen view of DNG in Capture One to output from Epson 3800 Maurice Link to post Share on other sites More sharing options...
barjohn Posted January 11, 2008 Share #16 Posted January 11, 2008 Please bear with me for a couple of posts. The first image is a selection of presets for LR. I have taken the same image, shot at ISO 160 at 1/250 using the SF-24d flash and just changing the presets and nothing else created a series of JPGs. I would like the experts on the forum to indicate which preset they think produced the best rendering. The very first image is the LR default with no presets. The wall in the background should be beige but rarely winds up being that color. The cabinets and woodwork are a dark brown like mahogany or dark cherry. Welcome, dear visitor!

sandymc Posted January 11, 2008 Share #19 Posted January 11, 2008 Well, a few comments: Firstly, looking at skin rendition on my (calibrated, professional grade) CRT monitor in Lightroom, I think that the "LovelyLeica" version gives the best skin tones, although that's definitely not what I'd say looking at the posted JPEGs. But I have a problem with the "LovelyLeica" version does to other colors - in a studio lit portrait that I use a lot as a test image, the LovelyLeica version turns pink lipstick into purple. I'm not sure that I'm willing to accept that.... Second comment is that the LovelyLeica version uses both the color controls and and the camera calibration controls. This was actually suggested by Ed Chatlos ("Shootist") in our previous skin tones in LR thread when I was complaining about the lack of a luminosity control in the camera calibration tab, but I never actually did anything about it. I think this is probably the way forward, and something I'll be trying next...... So in summary, I think we're making progress, but I'm not yet happy with any of the solutions.....
