Interesting, because the halo does not show up at all in the original image you posted, so it must have been introduced through some of the processing applied. As Armadillo said usually through overdoing the tone mapping.


This is the original raw normal exposure with no alterations at all taken into Photoshop and a High Pass Filter added at 149 pixels. There is the mystery halo on the original image. No idea why or how. Any ideas my friend? I am baffled I have to admit.

It seems the High Pass Filter is just doing exactly what the tone mapping presets in Photomatix do which is to exacerbate the areas where you have light to dark transitions, which creates the halos. The only way to avoid the halos that I know of is to completely avoid the tone mapping and to be really careful how you process such images. Once the halos are produced it is extremely difficult to get rid of them.

I was never really convinced this image was a candidate for HDR so should have followed my first thoughts.
I am stubborn by nature and will no doubt not rest until I find a way to eradicate them Using luminance layers and the channels pallet may work I think. Its been a long time since I did any so if Im not around for a few weeks you know what Im doing lol

Sounds like you know your way round Photoshop better than me … I'm still learning, in fact just ordered a book that will have some of that stuff in it, so I might be busy too.

Just a sign of a misspent youth my man!!! Luminance layers is a way of producing HDR without the software like Photomatix etc. You basically lighten areas of the dark image and darken areas of the light image and merge them with the normal image. Sounds easy huh. Do not believe it!!!
Interesting but damned hard to get right. So I may have a play but do not fear Photomatix will be back in action real soon.

There are aspects of the HDR photo that blow the unprocessed photo away. The detail in the clouds, for example. And I like the HDR 'texture' in the foreground subjects. The ONLY thing that bothers me is the haloing.
That said, I'd try exposure fusion rather than tonemapping because the latter tends to bring these haloing artifacts in.

The halo is in the original photo so even though it was accentuated by tone mapping what ever one does its going to be around. Normal (non HDR) PP hides it so its just not an ideal candidate for HDR. I tried fusion
and contrast optimising and hey presto I got my halo!!
Put this one in the "crap happens" folder I reckon.
Thanks for dropping by and commenting my man I appreciate your interest

You're welcome. BTW, what was the make and model of the camera body?

I am a leper in the photography world, an outcast, ridiculed at Camera Clubs, looked upon with pity by many and used to Nikon and Canon men unable to look me in the eye without a sympathetic smile.

I carry a Pentax K20d my man. Its been dropped on hard floors 3 times then totally immersed in water when a wave at the beach hit us. Its a tad battered and scratched but every day it works.

I never heard anything about Pentaxes doing weird manipulations to produce RAW files. But I'd be inclined to forgive a camera that survived three drops and a dunking (salt water?) a whole lot.

I briefly skimmed this thread, and I can show you how to easily fix that halo problem in post. I used to do daily blog posts and have a good archive of tuts. Here is what I consider to be a good one for your problem here.

Have a good one, Tom

It is contrast/sharpening in post.. I know you say its a raw file however an algorithm is applied to the image for you to even view it. This is why images look different in Lightroom, Eos Utility, NIK, Capture One.

I find that using the OEM software to process the initial development of your images yields a far better result because the OEM processing software uses the same algorithm as the camera. I.E. there is no interpolation.

If I am working on a photo that has to be perfect I process in OEM software first (raw conversion) because I find there is less artifacting than the aftermarket software. What I am saying is the image looks most like it did in camera, because again its the same algorithm on the computer that is used to show you the raw on the LCD scree in your camera.

If I have to get creative, I further process the the converted Raw in Photoshop. Mostly I just use LR to process everything, but if its critical I use OEM.

Your first picture is Great! To me anyway. I have been bouncing between HDR and some effects I can add in Lightroom. I took your first picture and manipulated it in Lightroom. Has a different results but like it equally as well. Could not make the clouds in Lightroom with as much contrast as yours. I tried this to see if Lightroom would get the halo effect as well. Lightroom did try to add the halo around the trees as well. I think it has to do with the way the sun is coming through from the back. Could have had different results using your original Raw file. Thanks for posting.

The halo is also on the original jpeg. I shoot Raw+Jpeg. So that was processed in the camera. I think its light playing tricks shining through the trees.
Im not a LR fan at all I must admit. I do not feel the need for tags flags and cataloging and I find it very limited compared to PS for serious PP work. Not having layers is like riding a pedal bike with one leg.
I certainly could not do what I do with just LR but I admit i do heavily process my work.

Hya my man. If you have Photoshop and can use layers you can get same effect on the clouds. PM me if you want to know more about how to do it. You outlined here why I do not use LR. Gets you so far and then you cant do what you want due to its limitations.
