[QUOTE="BackdoorArts, post: 371976, member: 9240"] And [I]this[/I] is where you're missing the point. The highlighted sentence is incorrect. What you are getting is what the camera is capable of capturing [B][I]in a single exposure[/I][/B]. Every sensor has a bandwidth called "[U]dynamic range[/U]" which describes the number of stops (EV's) that it's capable of capturing in a single exposure. DxOMark puts the Dynamic Range of the D3300 at about 12EV's. That's pretty damn good, and it's likely enough to capture just about everything you'd want in most average outdoor scenes provided you [I]nail[/I] the exposure. But it is nothing compared to what the human eye can see (~24EV), and nothing compared to what the sun can do shining through a small window in an otherwise perfectly dark room. [I][B]High Dynamic Range (HDR) Photography[/B][/I] allows the photographer to access light information [I]beyond[/I] the capabilities of their camera by capturing multiple exposures bracketed in a way that captures [B][U]all[/U][/B] available light.
