... You shouldn't have to re-examine and carefully parse every sentence to understand what someone is posting though, it should be clear on first read...
To be clear on first read, several factors need to converge:
1. One needs to write at an elementary-school reading comprehension level.
Are You Smarter than a 5th Grader?. All bets are off if someone ventures beyond that level
2. One needs to understand what HDR is
3. One needs to be familiar with basics of formal logic (e.g., syllogism):
Major premise: HDR opens (lightens) shadows
Minor premise: Shadows in the OP photo are too dark, blocked (i.e., the opposite of open)
Conclusion: The OP photo is thus not an HDR
I, however, sympathize with your apparent inability to synchronize all three pre-conditions.
