Here is simple example when sensor DR and sensor IQ are very useful.If you think the second image is an improvement then we are talking about different things.
+2, the second image is why HDR also stands for Horribly Divergent from Reality.
1. Interesting enough that all who replied did not get to the main point of the post and immediately started to tell how ugly the second image is))). But second one was not main point of the message but just previews of how initial image was pushed in processing and preview was done by windows snipping tool and was not supposed to illustrate anything – just to give idea to which extent initial image was pushed in processing.
Main point of the post was different and was illustrated by 3 image and that was that when sensor has good DR and IQ it would allow to get similar results as multi-shot HDR images without any efforts and time spent and allowing to push hard processing limits without introducing any visual processing artifacts like noise, halos etc. even when image is “overcooked”.
So this was illustrated by 3d image (100% crop of the second image) showing that even when image processed to the limits it does not have noise, halos on extreme contrast transitions and it resolves details up to the every pixel.
2. Example itself was just “Technical example” using image which mostly contains small details with uniform colors across the frame not clearly seen on small image especially on preview done by windows snipping tool.
This is kind of images are most difficult for HDR and could be seen well only with high enough resolution.
Best for HDR are shots with big enough objects of different colors in the frame.
So now I attach better preview of the second image in the first post - directly exported with better resolution.
The same is for 100% crop which is the illustration of the main point of the post explained above- now directly exported from image processor
Also one more image that was not pushed so far and processed to have more realistic look – just compressed DR to fit visual limits – no black or white clipping and a little bit of contrast added in shadows.
Probably most will find that more pleasant for their eyes.
And also 100% crop of it – to illustrate once more that was explained above about absence of visual processing artifacts usually found on muli-shot HDR images
Click on any image to open it and see with better resolution.
In any case all that images should not be considered as final images - that is just first step of processing - DR compression to fit visual range. After that person could adjust it to personal taste by doing selective color editing (contrast/saturation/luminance) differently on highlights, midtones and shadows and doing other kinds of tone mapping processing using most suited tools for that.
Hope all that would clarify what I was trying to say in my previous post
