Jamie Roberts Posted March 7, 2007 Share #21 Posted March 7, 2007 Advertisement (gone after registration) @ Jaap--well, let's say superior head-scratching over this. This purple fringing gets pretty wild on some systems (and not the M8, BTW). @ Georg--good luck! C1 should let you control this very well, and you need to watch the highlights; easier to pull stuff out of the shadows than recreate the blown mid-highlights here, but the DNG should be lots better. BTW--if any of you have critical shots that have these artifacts, Shay Stevens has a great, and cheap, PS action that completely removes (grays out) the fringe. Very nice (and not developed for the M8!) Link to post Share on other sites More sharing options...

sps Posted March 7, 2007 Share #22 Posted March 7, 2007 I've seen this in JPG's where I have the sharpening turned on. Make sure sharpening is turned off in your menu. I don't know if the color space setting would affect this, but fwiw I am using the AdobeRGB setting. My JPG's have been exceptional using these settings and manual white balance.

Jamie - I will permit myself one last grumble before bowing finally. I still believe that IR can and will create OOF secondary images around IR-active highlights. But as I said - there are heavyweight experts on this forum. Link to post Share on other sites More sharing options...
lmf Posted March 7, 2007 Share #24 Posted March 7, 2007 Wow, thanks for the tips here. I have dozens of nightshots with red-magenta haloes everywhere. I always thought they were ruined by IR oof (not having filters until recently) and now developing them with bibblepro the are suddenly all ok. Never thought the jpeg engine in the camera was that... bad. Link to post Share on other sites More sharing options...
sergiolov Posted March 7, 2007 Share #25 Posted March 7, 2007 This fenomenon, that you so lucky people see very seldom, is the terror of aerial photographers. I am fighting it for many years. It s relatively marginal with the m8, was terrible with the kodak 14n, and practically absent from the d2x and 1dsII. It is called magenta specular higlights, is one of the consequences of the lack of an antialiasing filter, and you can find a lot of threads on it on the Kodak srl forum on DPreview . Only solution (it is not jpg related) but not always working is to select the magenta in PS and desaturate. It clearly appeared on one of the first dngs published from the m8, the first test of Uwe. If you think it is a problem with the m8, try a Kodak..... A few examples. Sergio Welcome, dear visitor!

jaapv Posted March 7, 2007 Share #26 Posted March 7, 2007 The roofs show some very fine aliasing too. Link to post Share on other sites More sharing options...
GMB Posted March 7, 2007 Author Share #27 Posted March 7, 2007 Advertisement (gone after registration) Ok. As promised here is the 100% crop from the raw file, developed in C1 (with Jamie's come file). No sharpening at all, no manipulation in PS. Guess I have to live with this. Welcome, dear visitor!

GMB Posted March 7, 2007 Author Share #28 Posted March 7, 2007 Just see that the 100% crop is too small. So here it is again. Raw is of course a huge improvement over JPEG. I should also thank Jamie for his profiles which are fantastic. Welcome, dear visitor!

I developed again the same aerial with C1 and your profiles, and most of the magenta is gone, whitened and not grayed in this case. Sergio Link to post Share on other sites More sharing options...
