gogopix Posted February 22, 2007 Share #1  Posted February 22, 2007 Advertisement (gone after registration) In taking several thousand sof images, and yes I have seen some magenta, and no, I dont do weddings, Ihave stumbled on an interesting pair of images  The first shows the magenta problem in the DMR (very slight, but there!). See tyhe RGB. This was a BLACK coat Interesting the sweater, WAS a bit dark magenta, and its RGB was LOWER percentage red even with this DMR.  the second shows how really great a 15mm image can be without any filter (OK its the R 15mm 2.8, and on the "M" it is just super as I think you will agree.  So bottom line, why go thru all the agony with filters? The vignetting in the 15mm on M is minimal, and with a small correction or Jamies prifiles MUCH less grief in getting a solid image WITHOUT A FILTER!

ken_tanaka Posted February 22, 2007 Share #2 Â Posted February 22, 2007 "Agony" seems an awfully extreme portrayal for filter usage. Â As you've discovered you won't need to use an IR filter at all times if you choose not to do so. But you will find that excessive infrared will alter the colors on many images, not just tungsten lit scenes. Normalizing these effects is not a one-size-fits-all process and is generally not possible throughout the gamut of most images. Â So if you do not need to do color-accurate work continue to eschew filters and try to use some form of color modification profiling when necessary. But these clear little filters are not exactly what I'd call "agony" to use. Inconvenient yes, agonizing no. Link to post Share on other sites More sharing options...
gogopix Posted February 22, 2007 Author Share #3 Â Posted February 22, 2007 The agony I was referring to is the post processing issues, cyan (note how clean and uniform the sky is on the 15mm image. It is really wonderfully clean in the original.) The coding doesnt seem to fix completely, the mix with vignetting confuses the algorithms - I'm just reflecting what I have read in many of these threads. Â The point to me was that being 'approximately right" and living with a little magenta/purple is better than 'precisely wrong' with excessively post processed anti-vignet, anti color skew, color balance etc. Â Take a filter image of a roadway, and getting the cyan edge casrt out seems much harder than taking out a few isolated polyester coats.

Â Good points. I have over 5000 pix thus far with my M8 and am going filterless except for the 75/2 which uses an easy to get filter size (49mm). I have a 55mm 486 for my 24/2.8, but the cyan corner is a bigger problem than the IR. However, and this is a big however, like many, I have been shooting it in winter; I suspect IR filtering will become useful once the leaves sprout (May up here in AK).

caloso Posted February 24, 2007 Share #5 Â Posted February 24, 2007 Somebody please ship me my filters. bought my m8 in december and have only shot 20pics with noctilux...I have been very busy. I went to the SF Symphony and put on my trusty 35 summicron to save weight. I got some good shots but knowing which performers wear synthetics is too much.

rvaubel Posted February 25, 2007 Share #7 Â Posted February 25, 2007 Advertisement (gone after registration) LOL! Willkommen bei Foto Huppert ? Â Yes its true, they have almost all the filters in stock... I even had all the filters I needed in my shopping basket. But when I went to check out, the fact that I don't speak German was an barrier that I could not cross. He could sell a lot of filters if his purchase/credit card instructions were in English. Â I know a women who speaks German...my only hope for filters before the next decade. Â Rex Link to post Share on other sites More sharing options...

Riley Posted February 25, 2007 Share #9 Â Posted February 25, 2007 just a note generally the peoples of Germany, Austria, Holland, Belgium and France speak 4 languages including English the lowlands of the Sudeten, Czechoslovakia, Poland, Romania, Hungary rather less so Link to post Share on other sites More sharing options...
rvaubel Posted February 25, 2007 Share #10  Posted February 25, 2007 What you need translated Rex? Peter  Actually navigating the site and finding the right filters was not hard. It is the filling out of all the customer and credit information that is a challenge. But I understand if I call I will someone will be able to help me in English . I'm so used to ordering stuff without talking to a human being that I find the prospects a little intimidation. Link to post Share on other sites More sharing options...

farnz Posted February 25, 2007 Share #13 Â Posted February 25, 2007 Rex, perhaps you should sign-up for that evening class, "German for internet shoppers". LOL. How long before someone invents 'Internet' as a common language? (Of course in the north of England that would be t'Internet. ) Â I believe they've already invented 'Teen' as a separate language: I certainly can't understand 'em! (Nomesayin?) Â Pete.

marknorton Posted February 25, 2007 Share #14 Â Posted February 25, 2007 I've just ordered a 43 for my old 50/1.4 - not in the range of Leica filter sizes - and a 52 which I hope will yield the right size filter glass for my WATE hood project. Â To be fair, I can see that if you speak no German at all, it might be a bit confusing. I can tell you though that "Telefon" is German for "Telephone"...
