That article describes exactly how "normal HDR" is achieved with a DSLR.
- fulafel 10y agoI don't think "normal HDR" traditionally includes this: "HDR+ addresses [low-light blur/noise] by taking a burst of shots with short exposure times, aligning them algorithmically, and replacing each pixel with the average color at that position across all the shots. Averaging multiple shots reduces noise, and using short exposures reduces blur."
- ynniv 10y agoReducing shutter speed to reduce blur isn't new (https://www.dpreview.com/articles/1528656007/notimagestabilization https://www.dpreview.com/articles/1528656007/notimagestabili...), accumulating sensor exposure is how DSLRs work, and aligning frames is how image stabilization works. It might not be what we call "HDR", but there's nothing new here. The combination in a phone camera sounds nice.
- puzzle 10y agoNormal HDR combines regular, underexposed and overexposed shots. HDR+ does not.
- andybak 10y agoYes but a lot of cameras have low-light mode which takes multiple shots (not bracketed). I'm still not seeing how this isn't a fairly simple combination of existing techniques.
