mmx_2 Posted July 20, 2013 Share #1 Posted July 20, 2013 Advertisement (gone after registration) Well, the picture sort of speaks for it self. This is the jpeg from the camera, but the RAW-file is also terrible. Lens is APO-MACRO Elmarit 100 shoot at f11 (tried also f2.8, same shit), handheld and autoWB. The second picture is the camera jpeg from a Canon G12. Has anyone experienced this before? I tried searching the forum but without result (read the thread about magenta shift with wides though) Canon picture On my flickr you can download the fullsize jpeg: Flickr: joakimlarsson1's Photostream DNG: https://www.dropbox.com/s/88unaefhnhvzhaj/L1005008.DNG Link to post Share on other sites More sharing options...

mjh Posted July 20, 2013 Share #2 Posted July 20, 2013 That’s an easy one: the red channel is overexposed. A negative exposure correction should do the trick. Link to post Share on other sites More sharing options...
thighslapper Posted July 20, 2013 Share #3 Posted July 20, 2013 M240 auto WB is flakey. Correct both WB and overexposure and use an M240 specific dual illuminant colour profile and you get this from the DNG in LR4 (all of 5 seconds work) ....... Using the Adobe Standard profile actually seems to improve things further...... See threads linked to Skin tones and you will see similar issues .... I feel Leica has not got the reds spot on as yet and the issue is compounded by some odd auto WB results as well.... although as Michael says most is a product of over-exposure... I have to say the Canon image still looks better though .... although the exposure is right to start with on this .... Welcome, dear visitor!

jaapv Posted July 20, 2013 Share #4 Posted July 20, 2013 Yep. You simply overexposed, blowing the red channel. If you use the RGB histogram you will pick it up when chimping. Link to post Share on other sites More sharing options...

Ok, funny, I've never had this on my M8, and I've shot these trains (it's our garden railway) hundreds of times (also in very strong sunlight). Never seen it on the Canon either, but you're the pros Link to post Share on other sites More sharing options...
hoppyman Posted July 20, 2013 Share #7 Posted July 20, 2013 Advertisement (gone after registration) Well the title of your post will certainly garner some responses Generally this refers to a "red edge" effect which can occur with some wide angle lenses in some circumstances with some M9 cameras. There are a few preliminary indications that this may also occur to some extent in some circumstances with the new M. As mentioned by others here your shot is not affected by that and was significantly overexposed (more than a stop according to my look at your DNG). I don't know whether Leica Camera will adjust the default JPG processing in future firmware or the embedded profile. That is not uncommon. I would expect that Adobe will likely update their Adobe Standard profile as more experience is gained by customers. Link to post Share on other sites More sharing options...

adan Posted July 21, 2013 Share #10 Posted July 21, 2013 My take-away here is that the M240 - exactly as with the M8 and M9 (and every other digital camera I've used shooting RAW) - requires a good, personalized, custom profiling with a Macbeth/Gretag ColorChecker. Virtually the first frame I shoot with any new camera is of the Macbeth chart under broad daylight, which picture I then open and use to build a color profile, such that the primary colors (r/g/b) on the Macbeth chart are reproduced correctly (as compared with the "standard" rgb values for those colors published various places on the Web.) The "canned" profiling provided by Adobe and/or Leica is never very accurate, so I long ago learned to ignore what comes in the can and do my own. People fussed and fumed that the M9 produced skin tones far too pink - until I did my own profile and showed that the CAMERA produced fine skin tones - once properly profiled. http://www.l-camera-forum.com/leica-forum/leica-m9-forum/102813-m9-skin-tones.html Link to post Share on other sites More sharing options...
k-hawinkler Posted July 21, 2013 Share #11 Posted July 21, 2013 Would it not be better if Leica got it right from the start? I would pay them $5 more for that added value. Link to post Share on other sites More sharing options...
hoppyman Posted July 21, 2013 Share #12 Posted July 21, 2013 However, Karl-Heinz what is "right" in the first place and according to who (cultural/personal preferences)? What the embedded profile produces? What the Adobe Standard profile produces? What looks appealing from the default JPG reproduction? With what raw conversion software and what developing settings? for what application... print, "average" computer screen etc etc? under what lighting conditions and so on and on?

Stealth3kpl Posted July 21, 2013 Share #13 Posted July 21, 2013 This is why God created incident light meters and raw files...and histograms. Is it possible that the meter is less sensitive to red light? This railway looks very nice. Can we see a link to more pictures? What guage is it?

jaapv Posted July 21, 2013 Share #14 Posted July 21, 2013 Would it not be better if Leica got it right from the start?I would pay them $5 more for that added value. There is no objective "right" exposure as it differs for each subject. Each camera maker chooses the compromise. It may even vary by model. We must get to know our camera in order to use it to best effect. In the case of the M there are a spot meter and matrix meter added. If you compare the three methods it can happen that you get three different exposure values. All are "correct" for that subject. It is up to the photographer to know which one works best for his interpretation. Link to post Share on other sites More sharing options...
Ted Lemon Posted July 21, 2013 Share #15 Posted July 21, 2013 Don't own a new M so cannot comment - but being a big kid very envious of a garden railway - how wonderful! Link to post Share on other sites More sharing options...

This railway looks very nice. Can we see a link to more pictures? What guage is it? Pete The gauge is 1:22,5 (G scale), 45mm track width and weather proof (tracks and buildings at least). It was invented by Lehmann (German brand), in 1968 but today a number of manufactures exist, ours is a mix of brands and is modeled after the German 1000mm Harzquerbahn. I can post some more pictures tonight:) Link to post Share on other sites More sharing options...
