Where halos come from

Please look at the picture full size on a grey background.

I was chatting with a friend about Lr4 and the myth that halos had been eradicated.

So I thought other people might like to be aware of all the controls that can provide an unwanted halos at an edge with greatly differing tonal values. This is largely a problem for black & white users of Lr. Colour photographers generally do not require the same high contrast as the senior service.

The over enthusiastic use of the following controls can give halos

  • Clarity
  • Colour mix
  • Over sharpening
  • Adjustment Brush Auto mask
  • Plugins – Silver Efex Pro 2
  • A combination of all of theme

So these are the places to look and retrace your steps.

The picture above “Deserted Farm Wales” IR capture, Gold and Sepia split toning.

A big hello to all the new followers of my little blog.

    With your using IR for the capture, I can’t tell if there is snow on the ground or not. If not, why are you using bluish tones? Seems inappropriate if the scene is summery.

      Hi Ed thanks for the comment. For me black and white is a medium of abstraction and extension without the need to replicate the tonality or tone of scene in nature. You pays your money and makes your choice. Just to confuse you a little more these where taken in October and no snow. Andy

    Hi Andy,
    Please put me out of my misery and tell me where Adobe have said they have eradicated haloing. Try as I might I can only find claims that LR4 has . . improved it . . reduced the problem . . and the like.

    I can mess up ANY image in LR4 and PS5 too, just give me 30 seconds and I would disprove the claim πŸ™‚

    But seriously, In my view, and that’s the key, I find LR4 a much better tool then LR3 was/is. The Clarity slider, for me, helps greatly to improve mid-tone contrast, but push it too far and OHHH!

      Hi Frank I was heavily paraphrasing Julianne Kost the Photoshop evangelist in a Lr4 beta video on YouTube. Perhaps I over did it a little, my apologies for your misery. Hear hear to all you say about Lr4. Regards Andy

    First off, sweet shot.

    And yeah, you’re right. I did a few tests with it to see how much it was improved. Vastly IMO, but it’s not perfect that’s for sure. I don’t think we cn expect it to be for a while now, but this is much better than what LR3 had, especially in the clarity slider!
