HDR Halos
Hi Can you help please with this problem, I shoot a lot in HDR then fiddle in Topaz and other third party images. Halos are a concern but I try to use them as a feature but in the case of trees they are a nuisance. I've tried adjusting with other methods but it makes little to no difference. I just need to plant some more colour behind and blend behind the leaves. If you look at the attachment where the top right tree line extends into the sky this is a classic problem and really need a PS CS4 fix. Any suggestions would be very welcomed. Thank you.  |

Re: HDR Halos
Halos are usually caused by over sharpening. Have you tried reducing the sharpening in Topaz? |

Re: HDR Halos
Removing halos are a problem preventing them is easy - When you apply Sharpening straight after use Image> Fade Filter set to Luminance. It's a lovely picture nonetheless. |

Re: HDR Halos
I would suggest that you always sharpen on a duplicate of the layer and create a layer mask, so that you can add sharpness selectively. However, I would keep sharpenening down to a minimum, i.e. amount 100 Radius <1px and Threshold 2. Much will depend on the image sizethough. I see so many pics ruined by liberal use of the filter and if people really want sharper pics, then invest in top quality glass (L series for Canon etc). Try the High Pass filter on a duplicate layer set to soft light as an alternative to unsharp mask. Nick |

Re: HDR Halos
Additional comment, not sure if it helps, but a few sometimes I get fringes. Using the lens correction defringe option in Camera RAW seems to do quite a good job of getting rid of them around tree twigs/leaves against a bright sky on the outer limits of edge of the EOS image sensor when in wideangle.

Re: HDR Halos
Many thanks for all your comments. The sharpening was the effect of Lucis and I do not get much of an option to constrain the effects. I am wondering if it is possible to overlay this area with another part of the sky then blend it in some way with the leaves etc. |

Re: HDR Halos
You could try taking the original uncoverted image and placing in a layer below this sharpened layer and change the blending mode of this sharpened layer to Darken. Not sure if that would work but you could try with different Blending Modes see what works, and play with the Opacity settings of the above layer. 
This example I took your picture made a copy and blurred it by 1 px dropped it below the original and set the top layer to Darken at 25% opacity made 3 copies of this layer with the same settings and another layer set to Luminance 25% opacity. It has helped clear up a lot of the halo and of course I'm working on this low resolution version so you will be able to get a much better image and with some careful masking you could make a near perfect job. |
