Hi everyone,
The following are some very early images from our recent Lake District vacation. All taken with an a99i and, most likely, a Sigma 24-70/2.8 EX DG HSM lens. The question is fairly straightforward I hope - do you see white 'fringing' on the B&W (especially on the hill tops) and on the colour versions as well? I suspect I have overcooked the Clarity slider in LR but other views would be useful. That's about the only difference I have made in processing these compared to other files from other (non holiday) locations, so I'm assuming that's where the 'fault' (if there is one) lies? Basic processing is performed in LR initially and a 'TIFF' file saved; this is then further refined (very minor adjustments and sharpening for end use - Sharpening is very, very slight in terms of settings applied) performed in PS Classic (CC version on-line). I've never been aware of this before and I am looking at these on my works monitor which is clearly not the one I do my work on, so perhaps this is where this is arising from. Files for the forum are also stored on Flickr - I have sen that this can also introduce some artifact elements as well? Feedback/suggestions/commiseration all thankfully received.... ![]() ![]() ![]() ![]() Thanks for the attention and best regards, Neil. |

Neil, to answer your question, yes I can clearly see the white fringing. To see if it's caused by "overcooking" or just exxagerated by normal processing it might be useful to post "unprocessed" as comparison (if you still have those).
Btw, love the light in the first shot! Edited by pegelli - 13 August 2019 at 17:28 |

Hi Peter,
This is exactly how the RAW file starts out: ![]() The RAW files are quite 'thin' and do need some management to bring out the depth seen on the day - suspect I've overcooked it.... Still - that;s the beauty of RAW files! Thanks and best regards, Neil. |

Hi Neil, I'm seeing some fringing in the raw file too, especially where the ridge drops below the cloud on the left, I've found that flickr does tend to introduce artifacts so I'm not sure if this is from that or whether its on the original file.
Beautiful photos btw |

Hi Neil, even in that unprocessed raw one I see a little white fringe and blowing it up (600%) confirms it:
![]() It seems the sharpening (increase of acutance) of the edge is quite strong and as soon as that's happening my idea would be that any further "cooking" will just enhance it to the point you find it a bit disturbing. So maybe the way to avoid it is dial down the (default) sharpening that's happening to the file early on in the process and in that way avoid exaggerating the fringe as you process the file further. Hope this helps. |

Hi Neil. The RAW file is imported into Lightroom with default settings and may not be neutral. Then in the export to jpeg the file receives various treatments depending on setting (output sharpening, resizing, compression). In short, I don't think you can judge a RAW file from jpeg output.
I do know that from your 'neutral' jpeg to the 1st 2 images you posted is a big leap in contrast. Perhaps clarity is the wrong way to go, I don't like the clarity slider and don't use it. I use NIK Vivenza quite a lot, it allows dodging and burning in a very pleasant way, but also that can be used to overcook. But processing is a personal thing and what works for one does not necessarily work for everybody else (is that why there is so much software on the market?). The proof of the pudding is in the eating Neil. Try to get the desired contrast without clarity perhaps? Success, Paul. By the way, really like the 1st one! |

Thanks, folks - I think this really helps me go back and rejudge what to do to get the most from these.
Rather irritatingly, the 'look' in the first B&W image is exactly what I was looking for for the final file so the fringing has rather 'upset the apple cart' in that respect. Paul - there are a few more like this to come once I master this issue! Interestingly, I do not see this level of 'fringing', even on the final file, on my MacBook with Retina display - it seems to be further exaggerated once it get's out into the big bad world. However, one other aspect that, perhaps, disturbs me more than this, and it's that I have recently had some major bouts of laser eye treatment ('Non-proliferative peripheral Diabetic retinopathy') and, whilst it has been very successful, I am currently more aware of small issues with my sight and, perhaps, I need to think more about what screen etc. I do this processing on so I can perhaps judge these types of effects more clearly. Too much to think about perhaps but the advice has, indeed, been very useful and positive and thanks for all your advice and thoughts - it's what makes this such a special place. Best regards, Neil. |

Not quite sure what's been done by you or by the various bits of software in the process, but if contrast and edge acutance / sharpness have both been increased then artefacts like those in Pegelli's image are quite likely to occur. Jpeg conversion also seem to add something. Have you tried dialling down the sharpness?

Neil, You asked for
"Feedback/suggestions/commiseration all thankfully received...." Sorry, but the best I can offer is commiserations... I went through a mountain of grief with basically the same problem. I eventually concluded that a version upgrade had made my sharpening defaults problematic. (However I use DxO so I wouldn't expect that your problem is identical.) The infuriating thing was that it only became obvious towards the end of my workflow when some Nik Colour FX tools (microcontrast?) made it much, much worse. In summary, commiserations & best of luck. ![]() |

Neil,
I really can't help as the PP software you use is all foreign to me. I've used Apple Aperture for decades, but with its pending demise when Mac OS Catalina updates next month, I've decided to freeze my old iMac in aspic running the present OS Mojave with all my Aperture libraries and vaults running off it. My new iMac will update to Catalina, and I've decided to simply use the native Apple Photos for post processing. That's plenty good enough for my minimalist approach to PP. Anyway, one thing that the Apple PP programs do is preserve the unmodified original file regardless of what you subsequently do to it. So if your original RAW files are still preserved, might an option be to start over again, this time being a little less aggressive with some of the tweaks? Just a thought.... |

Here's a good tutorial about getting rid of halos and fringing like this.

Thanks, Rob - there's a lot in there that I need to get my head around!
I think it does point to one definite thing though - I need to get some 'proper' PS skills in my life!! ![]() ![]() I'm running through some revised images from LR and into PS with less aggressive settings applied and I think it's improving matters - will share at some point. Thanks again to everyone that has contributed - very much appreciated. Best regards, Neil. |

Hi, I like your pictures!
If you plan to print them larger as 100cm poster you should worry about this 'problem' of fringe. If used digital or for smaller print, I think it is not a worry at all! |

Such nice shots! Here's my 0.02: -- The crest of the hill is very sharp naturally and seems to be highlighted by the ambient light. Your Clarity slider may have amplified this. I think it might be helpful to have an inexpensive print made. I'm not sure how large you anticipate displaying these, but you will get a better idea if there is a serious problem.
I would like to see your final images. |
