I didn't like HDR. So I'm not gonna write much. Maybe I just wasn't in the mood for it. Maybe it will turn out to be my next frenzy. After all, I hated joiners to begin with. Argh, no, I hate HDR. It's boring, and since when has the sky ever been green? Seriously it looks stupid and OTT.
Basically you take 3 photos (or however many you want to). One is correctly exposed, one is slightly under exposed, and yep you guess it one is slightly over exposed. You also have to use a tripod unless you want an even more stupid image. You put them all together and you get a really silly photograph. Nice one.
Thanks though Esme for standing out in the rain for me ;)
