AlbertoDeRoma Posted February 12, 2010 Share #1 Posted February 12, 2010 Advertisement (gone after registration) I was reading the recent discussions about bokeh, and read some comments about "contour doubling" or "edge doubling". Is the edge effect in the background in the picture below what people are talking about? I must admit that it's not very attractive, and I have to assume it's a function of the lens and that there isn't much one can do about it ... right? Thanks, Alberto M8, 28mm 'cron Link to post Share on other sites More sharing options...

johnkuo Posted February 12, 2010 Share #2 Posted February 12, 2010 Looks like there's some heavy post processing applied and this can be a by product of settings such as the Clarity slider in LR or the equivalent in other software. Link to post Share on other sites More sharing options...

perb Posted February 12, 2010 Share #6 Posted February 12, 2010 This rings a bell. I have seen other threads recently, but struggle to remember where. Do you use Lightroom? Could it be a bug/feature in some LR release? Just throwing memory fragments around Regards Per Link to post Share on other sites More sharing options...
brianv Posted February 12, 2010 Share #7 Posted February 12, 2010 Advertisement (gone after registration) Does not look like Bokeh to me, but some sort of post-processing artifact. This is the sort of thing that you get from convolution type filters. Sonnar "T" 5cm F1.5 in LTM, wide-open, and at closest focus: The above example is more of the Double Bokeh. Even more over-correction for spherical aberration in this Nikkor-S 5cm F1.4 in S-Mount. Wide open. Link to post Share on other sites More sharing options...
LourensJ Posted February 13, 2010 Share #8 Posted February 13, 2010 Did you use Silver Efex for the processing part? Link to post Share on other sites More sharing options...
Guest WPalank Posted February 13, 2010 Share #9 Posted February 13, 2010 My guess is that he used the plug-in Nik color-Efex Pro, "tonal contrast" somewhere along the way. That can create those sort of edges if you push the contrast to far. Link to post Share on other sites More sharing options...
wstotler Posted February 13, 2010 Share #10 Posted February 13, 2010 Wide open. I just wanted to take a moment and say everytime you post these shots I hate you a little more. This series with the foliage is SO damn good I'm positively green with Shooters' Envy. You're making me work! Thanks --Will Link to post Share on other sites More sharing options...

wstotler Posted February 13, 2010 Share #12 Posted February 13, 2010 Wide open. I just wanted to take a moment and say I hate you for having shot this series. Every time you post a shot from the set it makes me crazy. The moment and lens was exploited so damn well and the photos have such a wonderful look that I'm positively green with envy.

Yes, the fill light function also creates this effect. Link to post Share on other sites More sharing options...
Bo_Lorentzen Posted February 13, 2010 Share #15 Posted February 13, 2010 That happened to me on a couple of portraits when I treated them with SilverFX, its something about the graduation not agreeing with the software, and suddenly there is a sort of halo thing going on. YUP, fantastic series.! . Link to post Share on other sites More sharing options...
thompsonkirk Posted February 16, 2010 Share #16 Posted February 16, 2010 Sharpening tools can also cause that effect. Kirk Link to post Share on other sites More sharing options...
mtomalty Posted February 17, 2010 Share #17 Posted February 17, 2010 That 'artifact' is very easy to create by being a little too heavy-handed with the fill light and recovery sliders in either Lightroom or Camera Raw Mark Mark Tomalty Photography Montreal Canada Travel Landscape Stock FineArt Link to post Share on other sites More sharing options...
