Because the eye rarely sees a shadow without some detail, I personally opt for trying to pull some detail out of the shadows without to severely flattening the appearance of dynamic range in the photograph. I found (again according to my taste) this image to be too contrasty and oversaturated on my monitor (which is calibrated). I'm posting what I would do with it. Again there is no right or wrong, because anyway it is impossible to get the dynamic range of a photograph to exactly correlate with perceptual DR, so you make adjustments somewhere or other, giving up something for something else you consider more important to the presentation of the image (in the manner you present it).

Hi kymarto - yes, I definitely prefer the hint of detail and color you have enabled in the clump of reeds. Not so sure with the reduced color overall. However, there are monitors and monitors. My printer gives a good rendition of what I see on my laptop, which I appreciate is no measure - my version looking to be brighter and more vibrant, save for the clump of reeds. Stay safe, Del

I have to disagree. I stuffed the pic into LR and there is detail in the area. I'm not saying that it should be done but that it can. Just kick the shadows up depending on how much detail you want but yet still maintain the sidelight. Like food season to taste.


Yes - I see two considerations - importance of the detail and how the deep shadow affects the overall pic.

Attached is a pic I shot a couple of days ago – there is a dark corner (bottom left) would you leave it or PP lighten it?


You could flip a coin, but I'd leave it dark. That's how Nature designed it.

When chatting dynamic range, it is not unusual for someone to say that the human eye has a greater dynamic range than does a camera’s sensor, but surely the truth is not so – a camera’s sensor together with it’s adjustable aperture can have just as great a dynamic range. The eye also has an aperture – which adjusts as the direction of our vision roams over dark and light areas, I have looked at brightly lit areas, conscious that in the corner of my vision are very dark areas. I have also been blinded by sunlight when exiting a darker house (equivalent to blown highlights)? Of course, this effect can be overcome with the help of the latest Ray-Bans.

The Dynamic range of the human eye is something approaching 14 to 15 stops. There are no know current camera's that has shown that range, yet.

A nice photo either way. Go ahead & do the extra post. You can always make a couple of copies & play around with them. If you don't like how the copies come out, just delete them.

My thought is to define your subject before taking the shot and use the light to emphasize the subject. In your example there are two subjects, the fall colors and the water body. Adding detail to the dark lower left corner wouldn’t do much to enhance the subjects. Some judicious cropping might be in order.

Always keep in mind that our eye has an extremely wide range of sensitivity to light. It is a trillion to one ratio. No camera can capture that ratio. This is a driving reason to do post processing to extend the dynamic rage of your image capture.

That said, I also believe that if you are very happy with the image you see up on your computer, then you should do nothing further with it.

Thanks all - great discussion. Nice to know better how we all think.

Correct.
Also the human eye isn't relegated to one image to process...it is constantly updating the image.
If we were looking at the posted image in real time with our eye...that dark corner would be well lit.

Yes - but if I point the camera (set to auto) at the dark corner, I get the detail. If a point at the sun-lit foliage I also get the detail. What the eye gets is a movie. We have cameras for that too - when and if we want them.

The inky thing does not sit comfortably within the rest of the scene.

My own fix would involve reducing its contrast, plus color tinting it to sort of camouflage it vis a vis its surroundings. Might slightly soften its very hard outer edge as well. A more ambitious editing practitioner might even clone over the whole problem.

Edit: I notice kymarto took a similar approach. I would further soften both contrast and detail resolution just a bit more ... but very clearly, “great minds think alike” (lol).

Yes - two solutions - I did wonder about the inky thing - hence this topic.

The human eye still is better than video.
Of course, we are talking here about photography.
There isn't a contest which is better.

I believe the shadow is fine as it is . The reason is acts as a lead in into the composition and creates an effect of spatial distancing .This also leads to an expanded feeling of depth ,as if stepping into the image . On Dynamic range My camera A Nikon D810 is reported to be 14.8 with the newest Sony at 15..The eye reported by most Experts in the field place in the 20's when not accompanied by blinding light .In other words our eyes have more dynamic range when closer to our base normal range I would compare this in my mind as our base ISO same as the camera where our Cameras greatest Dynamic range is at base ISO ....when our eyes have acclimated to the scene . It is the same as why a pirate wore a eye patch at night . When the eye was uncovered he could see better with that eye because it wasn't blinded by lantern light. It is also why red light is used in boats at sea when navigating at night .https://photo.stackexchange.com/questions/21579/how-does-the-dynamic-range-of-the-human-eye-compare-to-that-of-digital-cameras
