Hello @flamer ,thank you for your kind compliment, I am glad to hear that.
I think i agree with your personal opinion, it will blur a lot of detail, especially in the foreground area if I bump up the value. However, it just my rough opinion, i haven't tried to open outside my pc. I guess try to look on the other side, it will enlarge my sight. So I am going to look in a laptop screen/ my smartphone outside my work room, and compare the result.
Currently, I have been working another deadline, so I will back to this one later. I also want to say thank you for your reminder. This original image larger than i have posted here, so the 2048 pixel it would not be big problem.
