how to lose detail while "simulating hdr" tutorial:
1) save HEAVILY COMPRESSED PHOTO:
2) increase contrast by 25
3) dodge the edges a bit to even out the exposure at the edge
4) layer duplicate
5) increase brightness by a lot, i can't remember, maybe 25-40
6) erase to reveal building
7) desaturate by a bit, tweak hue a little with hue/saturation tool
sorry, my burn/dodge anyhow do, but given a bit more effort i can probably end up with a sharper version still.
so i have no idea what you have done to the picture, seems like a lot of effort to destroy detail that can be done with simple steps as detailed above.
for your future reference, thanks. i rest my case.
