Luminosity masking is a powerful approach to compositing exposures for sure. One of the major issues with it is the lack of physical reality it often introduces into the tones of the composite image. Usually, the artist will decide that the sky from one exposure will look good with the foreground from another exposure, etc. and mask the one into the other to get pleasing exposures for each element. However, while this may produce technically noise free and pleasing color for each part of the composite, the relative exposures may not be realistically or visually compatible compared to how our visual system would interpret the scene.

This is obviously an artistic choice, but I often look at images that have been produced with luminosity masking and get an impression of the scene that is "not quite right" visually. Again, just an observation.

HDR merging adds light linearly, in a physically correct way, to produce the reference 32bit file. Various tone mappers try to compress the tonal range while preserving the perceptual contrast of our visual system. Sometimes I will tone map an HDR dataset to get an impression of the relative exposures of various areas or features in an HDR scene and then use that result as a guide to a luminosity mask composite, where I can manually do a better job of deghosting or compositing than the more automated HDR merger.

Learning the concepts behind Adams' zone system and trying to establish a visual impression of various zones in a scene will also help in the preparation of the composite image when using luminosity masks. While observing the scene, the photographer can make some notes about their impression of the relative exposure of the sky versus the foreground, etc. and then attempt to preserve this relationship in the luminosity masked composite.

Nice!
Where?

Looks like Adirondack guide boats.

You can hire these rowing boats and go for an excursion around the lake or alternatively you can be guided in one of the tourist boats

I'm not answering for Woolly, but I think he's from Scotland.. So they may be from there.


I was admiring the boats also. However, I do enjoy the Adirondacks, spend lots of time in those Mts.


**Edit** I see Woolly has replied

Thanks for your reply.
My father has an affinity for the mentioned guide boats, i will be pointing him towards your image. i wonder if he knows from whence they derived their design. (assuming the old world had them first ;) )
The local boats were lighter, and have a taller bow then your boats, but truly do look similar in construction.

There is no comparison IMHO between this technique and the others you posted a couple days. Very natural and a great image! (watch the slit halo on the top of the big rock)

Thanks Blake you are on point about the slight Halo, I was on my early learning process into the world of Luminosity masks at the time. Since then I have learned how to easily remove them, using a couple different methods.


ejenner wrote in post #18429771 (external link)
Agree. When you use Lum Masks, you sometimes will still bleed into other areas (assuming you are brushing in the effect). You can either amend the mask, or remove the halo afterwards. Either way you will need something else to select on. In this case (and most cases in landscapes) the magic wand will do the job. For instance the sky around the rock is a distinctive hue. Using the MW with a small tolerance to build up a selection and then with the black brush erase the lightening you used for the rock in the sky.

If the halo is due to the HDR itself, then you will need to use a light mask, maybe adjust it with a curves adjustment and then darken carefully around the rock to reduce the halo.

The very upper edge of the rock looks like possibly a sharpening aritfact. There are two options here, either don't apply sharpening, or reduce it significantly on that edge, or go over it carefully with a clone tool.

I think this image is worth the extra effort to get it 'perfect'. It's actually pretty quick with this image. This took me just a few mins.

Thanks ejenner for also shinning in, agree, and you are on point like Blake.. See the comment I left for him

Thank you so much :-)

Yeas, the clean air (and plenty of exercise) has a lot to do with it - but I could do with quite a few spare body parts now :rolleyes:

Yes clean air is definitely one of the components, also the higher in elevation the better. Exercise most important as well.. I thinks in years to come science will progress to the point the body parts factor wont even be in the equation, unfortunately not in yours or my time on the planet.

Good point, to have in your arsenal first, a tone mapped image before creating the luminosity masks.

Will look into it deeper any glitches using ML?
I have used ML for around 3 years or more, started on the 600D, to date never had a problem, I think people worry to much about ML but on a user ratio basis I would think only 1% have had big problems. I only use it for stills photography as have no interest in video, Dual ISO with moving subjects is good as is the fact that you can extend the Canons option of only 3 bracketed shots on a lot of cameras, Focus stacking again I have used with good results but my advice would be as it is free try it on the 7D if you don't like it there is an option to remove it from the sd card and revert back to Canon only options.

Many Thanks,
Russell.

That Panasonic was my first try at a 'better' camera. In good light it produced quite nice pics.

Hi Ian :-)

It was my second Panasonic bridge camera, I started with the FZ5 - superb but no RAW. The FZ28 did not take such good shots, the resolution at infinity was poor -?
