Heggie Posted August 29, 2011 Share #1 Posted August 29, 2011 Advertisement (gone after registration) I've got a separate post going on concerning ghosting/doubling towards edges of frame with the Elmarit. I've also discovered another quirk in that highlights and detailed areas quite often display rainbow colours/moiré. I know extreme contrasts can produce this but I've also noticed it in fairly 'flat' areas of pics. Is this the price for having no AI filter? It shall be a time consuming process having to fix on most images. Unless I just stick to B&W. I've attached crops: Aperture 2.8 on trees pic, 4 on windows pic. 320 iso. Welcome, dear visitor!

Advertisement Posted August 29, 2011 Posted August 29, 2011 Hi Heggie, Take a look here I can see a rainbow... 28mm Elmarit ASPH. I'm sure you'll find what you were looking for!
jaapv Posted August 29, 2011 Share #2 Posted August 29, 2011 Yes - use Capture One as raw converter. Moire and purple fringing. Link to post Share on other sites More sharing options...
Heggie Posted August 29, 2011 Author Share #3 Posted August 29, 2011 Thanks for that. I just quit firefox before I sent this message so here goes again! (abridged version) I was/am reluctant to buy more software without exploring LR3 more. However I did download the C1 demo for a look. In LR3 I found changing the process under Camera Calibration from the default '2010' to '2003' seemed to improve things greatly. Moire was pretty much eliminated/desaturated, however, in the pic detail of the Georgian windows rainbow effect I had to go in manually with the brush. Although a rough experiment, it didn't take too long to desaturate/adjust exposure and pretty much improve things in the effected areas. I also toggled between embedded and adobe profile, and combined it with the defringe edge option which helped with some cyan highlights. This may be historic news to users here (and elsewhere) so apologies if this all makes for an uninsightful read. Welcome, dear visitor!

rscheffler Posted August 29, 2011 Share #4 Posted August 29, 2011 One side effect of LR3's defringe edges setting is that it can affect (lower) overall image saturation if there are a lot of edge transitions in a given image. Naturally, you can boost saturation again with the saturation and/or vibrancy slider. Another 'trick' can be to move the saturation slider for the offending colour to -100 if none of the subject content contains that or a related colour. This works better with purple fringing, such as tree branches/leaves against a bright sky, than it does for moire problems. Link to post Share on other sites More sharing options...
