HDR photography replaces the need for lighting equipment when you need to photograph real estate interiors with window views.
With HDR, you take several exposures -- short exposures for the highlights (windows), and long exposures for the shadows (interior).
You just need a camera (DSLR or compact) and probably a tripod.
The camera can be a DSLR, mirrorless or compact camera.
The most important feature to look at for HDR is AEB (Automatic Exposure Bracketing). With AEB, the camera takes three or more exposures when you press the shutter button.
Most DSLRs include an AEB option, and some compact cameras do also. However the AEB capabilities differ depending on the camera.
For interiors with bright windows, it is best if the AEB settings allow at least 5 shots spaced by 2 EV, or at least 9 shots spaced by 1 EV.
You can check and compare the AEB capabilities of many camera models on the AEB Settings List.
To summarize:
You will need a tripod if:
OR
Note that using a tripod is always better. You will need long exposures for the dark parts of the interior, and these will be blurry if you take them hand held.
The choice of the lens isn't specific to HDR.
A wide-angle lens is a good choice for real estate interiors.
We recommend that you avoid using a lens that is too wide, especially a fish-eye lens, as they require significant post processing to correct for lens distortion.
