One RAW File 3 exposure action

Understood!  Perfect explanation.  I will try using the single RAW images from the drone.  I probably should have noted that we are a real estate photography company so we deal with those extremes all the time.  We shoot about 30 properties a day so a good part of it is also easy (high volume) workflow.  Thank you for the explanation, my friend!

I am not being combative but do have a question about that.  If you can do such magic with ONE RAW file, why does anyone use Photomatix for merging at all.  I really am just asking that question.  I use that technique with exposure fusion (not tone mapping) to create my base image.  I then begin the hand edits in Photoshop.

Thanks for the info, guys!  I normally use 3 .jpgs with different exposures for merging into photomatix.  I do this when using my stationary camera.  However, i am trying to do the same thing from a DJI Mavic 2 Pro at dusk.  Therefore, i thought there would be to much movement to get 3 identical .jpgs to merge.  I saw online that doing what i am looking for creates a "faux HDR" and the results i have seen are really good.  However, i have not found an action that will do it.

+1 Dave and Chuck. It makes no sense.

With the current process versions, this can be done with a single ACR instance and appropriate use of the sliders. This is from Lightroom, but ACR works identically:

I would think it would be better to open the RAW file as a Smart Object layer and then create independent smart object copies  using Layer>Smart Objects>New smart Object via Copy.  Abject the RAW conversions in the other smart object layers by changing their RAW settings.   You would have multiple RAW conversions in a single document.  Layers you can mask and blend together to get the conversion you want. Develop Highlight and shadows aeries better

I'm with Dave on this. It doesn't really seem to serve any purpose.

Hi

Your question is clear and JJMack has given you a method but I am puzzled as to what the purpose is.

Normally you would use a series of real exposures each captured as a raw file and then combined into a single HDR file to extend the dynamic range captured well beyond the capability of a single raw file which usually has 14 bits. However by starting out with a single raw file you are not extending the captured range at all and all those 14 bits can be brought into a 16 bit file without multiple passes or use of an HDR file.

That should be east to do with the plug-in  Image Processor Pro.  You have it saver 3 jpeg Images,  The first one you use an action that  a -1 exposure adjustment layer before the scripts saves the jpeg. the second one you use not action just save the normal auto exposure and the third you use an action the add a +1 exposure adjustment layer before the script saves the third  jpeg.  The image Processor Pro plug-in Script is a Free plug-in on the wen.  You will need to record two one step actions to use with the script.  menu File>Automate>Image Processor Pro.   You can also use  it from Bridge  menu Tool>Photoshop>Image Processor Pro...,   

The Script is a plug-in therefore you cams record an Action toe add the two actions automaticly.  To process the same input folder of raw Files or make the Image processor Pro step interactive so you can select the input folder of images
