Preprocessing: Manual Expoosure Bracketing This is the bare bones, free standby When all else fails, set the exposure one image at a time MUST use a tripod! Remote shutter cable or 2 second delay for long exposures
Manual Exposure Bracketing Put your camera into A mode (aperture priority mode). You will do the actual shoot in M mode, but the A mode allows you to easily measure the right shutter speeds for your scene. Choose the right aperture. This depends on the lighting of the scene and on the depth of field you are trying to accomplish. Choose the lowest possible ISO sensitivity to avoid noise in your photos. Put your camera into single-point focus mode. This lets you manually select the point that your camera should use to focus and to measure the exposure. Set your focus. You can use the autofocus to get your main subject in focus. Switch the AF off once that s done. Otherwise, your camera may decide to change the focus in the middle of the MEB series which would require you to start from scratch. Put your camera into spot metering mode. In this mode, only a small region around the active focus point is used to measure the exposure. Spot meter the highlights then the shadows. This will set the range
In-camera Automatic Exposure Bracketing (AEB) Much faster for supported brackets (3, 5, 7, 9, or 11 brackets) Easily hand held for high speed daylight images Falls back to semi-manual for Very High Dynamic Range images when multiple sets of exposures are required. A tripod is required for multiple sets
Link to Original In-camera AEB
In-camera AEB - Notes The above chart assumes a f / 5.6 lens which everyone has and 30 seconds or less exposure so we don t go into the dreaded Bulb Mode. The 30 second shadows dictate ISO 1600. Lower ISO solutions: Fast Glass or Darker Shadows F / 2.8 lens is 2 EV (stops) faster. That s ISO 400 or 7.5 seconds On the other hand, go deeper into the shadows with ISO 400 At Deerfield a lens in 16-35mm FF or 10-22mm APS-c is ideal. The f / 1.4 lenses have a 4 EV (stop) improvement. That s down to ISO 100 with reasonable shadow details There are several > $500 24mm & 35mm prime lenses available

Postprocessing: Lightroom HDR Photo merge Adobe Photography for $9.99 / Mo Now three plans: Lightroom CC plan with 1 TB of cloud storage for serious phone photography Photography plan with LF Classic, LR CC, and Photoshop with 20GB cloud storage Photography plan with t TB of cloud storage for $19.99 / mo The plain old Photography plan is the one I have. The HDR is OKay for plain daytime images, not so good for complicated images Output is a DNG Raw file. The deghosting scheme works but touchup may be required. No Batch capability
Photoshop High Dynamic Range Images Included in the Photoshop plan Good to create 32 bit files tone mapping is improved but not great deghosting can be a challenge No batch capability Can edit and use 32bit files created in any application! Layers and many of the blend modes, filters. And tools can be used to edit 32bit files for subsequent tone mapping in photoshop or other tone mapping applications
Nik HDR EfexPro One of the best, still free from DXO The NIK upoint technology works on the 32bit image to enhance all the image! Can make 32bit files from Bridge, Lightroom, or use 32 bit files in Photoshop The deghosting scheme is pretty effective The Nik collection is a steal that should be added to everyone s toolset.
