lepremier Posted June 17, 2007 Share #1 Posted June 17, 2007 Advertisement (gone after registration) I know that this subject, colour caste, has been done to death since the M8 came along but up until now I have not had any problems, mechanical or otherwise,,,apart from when shooting some magenta orchids. However....I have just been shooting some black fabric which has come out as purple. I have tried different WB settings etc but none of them produce a "black" image. I am obviously not an expert in this field but this has taken me a little bit by surprise. The only filter that I have on the lens at the moment is a standard UV Leica one. Still waiting for the promised correction ones.......since long! Would one of you "profis" care to explain please...thanks. Keep it simple!!!!!

chris_tribble Posted June 17, 2007 Share #2 Posted June 17, 2007 Hi - as you say. it's a long list. For simple reliable colour the best solution is to have an appropriate Infra-red cut filter (B+W make these if you can't wait for your Leica one... you should be able to get one from Gope Photo if you're in Sinagpore). Although there are work arounds - check out Jamie Roberts contributions: http://www.l-camera-forum.com/leica-forum/leica-m8-forum/9637-new-m8-profiles-c1-instructions.html - most of us find that this is the best solution for colour work. If you've not received your filter from Leica yet contact M8 Support [M8.Support@leica-camera.com] and check. I've found them to be consistently helpful.

lepremier Posted June 17, 2007 Author Share #3 Posted June 17, 2007 Thanks Chris...I am using LR and not C1 and I understand that the profiles are not set for this?? How do you know Gope's from London? Link to post Share on other sites More sharing options...

chris_tribble Posted June 17, 2007 Share #5 Posted June 17, 2007 Peter - in Lightroom it's tough unless you use the IR filters... The only thing you can do that I'm aware of is to play around with calibration - but it's a kludge. IMHO to get the colour right out of an M8 (especially in LR) is to use the filters. I have no problem with this - apart from the fact that I'm still waiting for an E60 - though I do have the rest on 7 other M lenses.. re Gope, I used to live in Sri Lanka and Dominic Sansoni recommended them... Used to get my Canon stuff from them and they were always good. Hope you get the problem cracked... Best Link to post Share on other sites More sharing options...
luigi bertolotti Posted June 17, 2007 Share #6 Posted June 17, 2007 Yep, magenta cast has struck me too... it seemed to me that was limited to black fabrics, but when I shooted my daughter ina dark blue dress... a terrible violet on the screen! But in the meantime filters have arrived.. Link to post Share on other sites More sharing options...
lepremier Posted June 18, 2007 Author Share #7 Posted June 18, 2007 Advertisement (gone after registration) Lucky you Luigi with the arrival of your filters. I ordered mine back in January and Leica replied today to a recent email advising me that due to shortage of stock they are unable to dispatch. Support in this part of the world sucks..... Chris...better luck with Gope tho', they are on the horizon. Another question tho'....why is C1 such a popular tool? I have tried, given up, tried again and given up again. I find that LR, for example, is much more user friendly to operate, for me anyway. Although the guru at my "local" shop says that C1 is simply a better tool.

Peter, which diameters are You waiting for ? Seeems to me incredible the time you speak of... I ordered my M8 in April, 1,5 months of wait, for I wanted it chrome.. just received the body, sent my request for my two filters (39 & 46) : 15 or 16 days after they arrived at home . And about C1 vs. LR... really it appears about a 50-50 for supporters of one or the other... lot of different views in this forum... I use LR, like it... I'll surely try C1 too...

ho_co Posted June 18, 2007 Share #9 Posted June 18, 2007 ...why is C1 such a popular tool? I have tried, given up, tried again and given up again. I find that LR, for example, is much more user friendly to operate, for me anyway. Peter-- C1 is the choice primarily because Leica has been working directly with Phase One to develop good processing for the M8. There were several posts on the forum in which people reported that the M8's colors turned out better with C1 than with other raw converters. I also don't find the user interface intuitive, but few raw processors are at first glance. Leica USA offered some M8 training seminars at which Scott Geffert did a nice job of demonstrating the program's basics. Justin Stailey of Leica USA is also doing some similar introductions. (I know that doesn't help you, but maybe there's a C1 users group or some such around.) Remember also that the coming update to C1 version 4.0 is supposed to offer a major improvement to the interface. --HC Link to post Share on other sites More sharing options...
Jamie Roberts Posted June 19, 2007 Share #10 Posted June 19, 2007 {snipped}Another question tho'....why is C1 such a popular tool? I have tried, given up, tried again and given up again. I find that LR, for example, is much more user friendly to operate, for me anyway. Although the guru at my "local" shop says that C1 is simply a better tool. IMO... YMMV... C1 is just a better raw converter--that's why it's (still) so popular. Despite it's being a bit weird to use (and it's not that bad, really) the output from it and its level of control is astounding. For one thing, it lets you use an input colour profile and to tweak that to your taste. So if you're a pro who shoots portraits and you want your skin tones to look the same under similar lighting, well, that's a snap in C1 with its integrated profile editor. Or if you want to minimise magenta shift unfiltered with the M8, there are profiles for that too. It also lets you output to a whole range of colour profiles appropriate for the print / output method. Photoshop/ ACR and Lightroom are both rather lightweight in this regard, and personally I think Lightroom's M8 colour rendition is poor (pretty clamped down--even in the primaries. Makes the M8's colour look aenemic to me). Having said that, Lightroom is v1.0 and C1 is nearing its fourth major release. Lightroom will get a lot better in the future; but so will C1. So I'd dig into C1 again and try it. It really does do stuff that a lot of other converters don't. One thing I'll mention that always confuses people... just ignore C1's way of organizing stuff into capture folders and the like, because unless you're shooting tethered (live from a computer) it doesn't make much sense. Instead, dump your shots with a card reader and back them up. Then fire up C1 and navigate to the folder with the shots. Let it build thumbnails. For the M8 (and DMR) this is essential because the JPEG in the DNG is useless. Go have a coffee if you have a lot of files (over a couple of hundred). Look through them quickly, tag the ones you want to keep and delete the rest (you backed them up, remember?). You can use the compare too to look at two at once, even, which I think is great. Then just output the shots you work on. Any setting (or all settings) from an individual shot can be copied to other shots, or any group of other shots. It really is worth the learning, curve, believe me. You'll be happier with your prints in the long run. Ok--you asked Link to post Share on other sites More sharing options...

luigi bertolotti Posted June 19, 2007 Share #12 Posted June 19, 2007 Thanks Jamie... precious advice for me, that, as I said, want to start with C1... the first 10 minutes of work with a Software you don't know are fundamental...and your quick advices can help al lot Link to post Share on other sites More sharing options...
sean_reid Posted June 19, 2007 Share #13 Posted June 19, 2007 The color shifts that are caused by IR are most noticeable in black textiles but they, in fact, can affect the color rendering of many kinds of subject matter (albeit subtly in many cases). Some people do not mind the color shifts but, if one does, the IR-cut filters are the only way to address the problem (more or less) at its source. That's why Leica has put all this effort into sending out filters, designing firmware changes to suit, etc. Jamie's profiles can help a lot but they can't fully correct the root problem. Cheers, Sean Link to post Share on other sites More sharing options...
andit Posted June 19, 2007 Share #14 Posted June 19, 2007 Hi Guys, Here's the proof that this is a universal problem. Just to pick up on what Sean said above, in this shot my brother and his daughter were both wearing synthetic black. They came out two completely different colours. So, even if you think that you don't have any colour shifts, they are sometimes so subtle that you hardly notice. At least since this photo was taken, I have received my IR cut filters, so this should not be problem in future. Andreas Welcome, dear visitor!
