jaapv Posted March 15, 2007 Share #61 Posted March 15, 2007 Advertisement (gone after registration) Guy, the thread David pointed out has a post that implies that one can tick the "pattern noise" checkbox in the lower righthand corner in C1LE to avoid this effect. It might be worth trying this out. Link to post Share on other sites More sharing options...

guywalder Posted March 15, 2007 Share #62 Posted March 15, 2007 Jamie, I re-processed, this time with noise reduction set to 1/4 (in my origonal it was 0/4). I played around with the banding suppression and pattern noise reduction, but they made no difference to the preview, although I didnt complete processing of those. 1st picture is as before, but with noise suppression set to 1/4 Welcome, dear visitor! As registered member you'd see an image here… Simply register for free here – We are always happy to welcome new members! 2nd & 3rd pictures are a comparison from the LH edge, which shows why I dont want to turn up the noise reduction! It also does horrible things to the tonal graduations in the sky. with nr: and without: Guy Link to post Share on other sites Simply register for free here – We are always happy to welcome new members! 2nd & 3rd pictures are a comparison from the LH edge, which shows why I dont want to turn up the noise reduction!

Jamie Roberts Posted March 15, 2007 Share #63 Posted March 15, 2007 @ Guy--interesting results. I think if I was shooting a sunset, though, I'd use the noise-reduced version, since a lot of those shots are going to be low in fine shadow detail. As for the mush in the blinds and tones in skies, I'd actually play with the profile and the sharpening settings; I'm betting (but it's hard to tell without the DNG) that you could get so close to what you want with NR off that it's not worth it. Personally, I prefer to keep NR at its default but the sharpening reasonably high, because I will sharpen at the end of my workflow (and it will be different for print or screen). And just FYI to those of you who might be new to C1.... The C1 large preview window doesn't show exactly what the develop will look like, no matter how much you zoom. The Focus tab preview actually does show a much closer version to what the final will look like. Of course, your JPEG level / TIFF output and profile will affect all of those things.

guywalder Posted March 15, 2007 Share #64 Posted March 15, 2007 @ Jamie, I am new to C1-LE, although my comments were about the focus preview window (call it beginners luck!). I was rather hoping that the full C1 has better/more subtle NR.... Looking through some other pictures similar to the one I posted, the same phenomenon occurs consistently, but only in a specific colour range. The posted picture is also the worst occurrence. I guess I'll have to knuckle down and start learning about profile optimisation @ Jaap, Our posts crossed.I tried checking the pattern noise box, but saw no change. In the meantime i found a picture from yesterday with some shocking moire, the pattern noise check box has an effect on that. I'm beginning to think that two different cameras / workflows / raw developers is going to cost me my sanity! Guy Link to post Share on other sites More sharing options...
Jamie Roberts Posted March 15, 2007 Share #65 Posted March 15, 2007 @ Guy--for someone new to C1, you're doing very well! The good thing, IMO, about learning C1 is that it truly is a fabulous tool when configured and optimised, and they're about to release a major upgrade that, from the hints I've seen, promises to be really great. The balance between noise and sharpening is subtle. I guess if I had a bright orange, very noisy object and very fine detail in an area of interest, I might, in theory, take care of the orange artifacts in PS and turn down NR. But in practice, I've found playing with sharpening in C1 (not too much, but some) to be more productive in final output. Subtle transitions--in any raw converter--are more affected by input profile than people might realise at first; it's why they're so hard to perfect (especially in things like skin tones and shadow detail). It's also why I like to use a raw converter with selectable input profiles Link to post Share on other sites More sharing options...
hrosell Posted March 15, 2007 Share #66 Posted March 15, 2007 @ Tashley - Sorry for what's going on with your camera. I am still waiting for my own and despite the somehow scary incidents I am still eager to receive it. Can you please confirm that both of your M8s have similar firmware which I guess is 1.092? Keep us posted with the outcome! Regards, Horacio Link to post Share on other sites More sharing options...
guywalder Posted March 15, 2007 Share #67 Posted March 15, 2007 Advertisement (gone after registration) @ Jamie, I've been doing my raw developer learning on Nikon Capture, I am comfortable with it now, as long as I remember to batch process Before captioning.... but NC is completely different to C1. I havnt done anything with the sharpening in C1 so far, I'll get started tomorrow! Guy Link to post Share on other sites More sharing options...

jonoslack Posted March 15, 2007 Share #69 Posted March 15, 2007 HI Tim It's happening in france as well: I can do this too: Here is the photo (underexposed) These are crops - the top one from Lightroom, the bottom from Aperture On the other hand, I shot quite a lot of similar shots, without the issue appearing in any of them: I guess it must be a sensor phenomenon, whether your second camera needs to go back or not I don't know. . . . . . is it black?!

Hello Jono! Come back soon, we miss you! I have returned the new one to Bart for exchange, (it was black) cos I have clarified that my original M8 doesn't do this, ever... sorry to be the bearer of bad tidings but I now understand your specular highlights sparkle thing...

waterlenz Posted March 16, 2007 Share #71 Posted March 16, 2007 So Tom, did you send yours back? And thank you for posting these! Tim No, it is a second wave body that came with 1.09. Tom Link to post Share on other sites More sharing options...
tashley Posted March 16, 2007 Author Share #72 Posted March 16, 2007 Thanks Tom, I just sent mine back because as a second body, I know from the first that not all M8s do this and mine was doing it on most shots with a bright thing in. Maybe firmware 1.1 would have sorted it but by the time that's released I'd have been beyond my return period and into the repair zone, where timescales are somewhat longer!

guywalder Posted March 16, 2007 Share #73 Posted March 16, 2007 I'll be sending mine back as well, some further tests today showed the patterns on traffic cones showing up on the lcd at 100% zoom Playing with exposure shows that it starts to happen as the orange/red starts to blow out I got it less than a week ago, with FW 1.092 ready installed Guy Link to post Share on other sites More sharing options...

guywalder Posted March 17, 2007 Share #75 Posted March 17, 2007 Tim, thanks, I am already convinced by the reduction in size and weight compared to my D2X set-up, and having dragged a few D2X files into C1-LE I am feeling happer with the M8 file quality (it all looked so different to start with, I am used to Capture, but not to C1...). I just need to sort this patterning problem, and build confidence in the reliability. Here's hoping!! Guy Link to post Share on other sites More sharing options...
okram Posted March 17, 2007 Share #76 Posted March 17, 2007 Hey, watch this. You can repeat this any time photographing your LCD. It is ppur aliasing and it happens at any color.

Shoot it at f4 at 1/30s and you won't see them. Those internal squiggle things means, I think, you've got a defective M8, or one that doesn't have the hardware fix but has the newest firmware, or something. Mine doesn't do this. I won't bore you with shots of the computer screen--take my word for it. Link to post Share on other sites More sharing options...
okram Posted March 17, 2007 Share #79 Posted March 17, 2007 Try it. take 1/30 and 5,6 with 50mm and change a few distances, but keep it sharp. It doesnt come up allways. Mine is 15days old and 1.92. Link to post Share on other sites More sharing options...
Micha67 Posted March 18, 2007 Share #80 Posted March 18, 2007 And you really really won't like what you see in the 100% crop. Answers on a postcard please?It´s clearely a sensor issue, which is only seen flanking heavily blown-out highlights. The phenomenon is due to either smearing or to an asymmetrical blooming. Considering the full frame architecture of the KAF-10500, blooming ist the most likely origin of this artifact.see also: CCD artifacts http://www.stsci.edu/instruments/wfpc2/Wfpc2_hand_current/ch4_ccd5.html#442757 Hamamatsu: Education in Digital Imaging - CCD Saturation and Blooming Of course, blown-out highlights at ISO-1250 are not necessarily as bright as blown-out highlights at ISO-100. Therefore, it is easy to explain, why the picture with the halogen bulb taken at ISO-1250 does not show the effect. Link to post Share on other sites More sharing options...
