I got it to run but waiting for it to finish. (957 files)
Using:
createStackedDngs('/Volumes/NVMe/mean', 'partialstacks', '1/4, 1/2, 1')

I think the issue is that I don't have enough space in my internal drive. Only 102GB and averaging 957 RAWs require more.

Is there a way to save the temp files in another volume?


'tempdir', 'path', for example: createStackedDngs('/Volumes/NVMe/mean', 'partialstacks', '1/4, 1/2, 1', 'tempdir', '/Volumes/MyVolume')

Hmm, the "Error while converting file: /Users/fredmiranda/Desktop/raw-files/_FM92436.ARW" message is from the DNG converter itself. Try converting that directory using the GUI version of the DNG converter and see if it successfully generates a DNG for that file.


I believe that error went away after updating DNG converter to 13.2.
I am running fine with Olympus M1m3 files, but get an error with ILCE-1 files:

error: 'sortedIndxes' undefined near line 527, column 527

Thanks, just checked in the fix. It wasn't specific to the A1 but whenever it found a file whose date excluded it from the stack currently being constructed.

That fixed the crash, but no output is generated for A1 files. Why is there a date issue? All 8 files are created within 1 minute.

From the readme:

'maxtimedelta', value - Sets the maximum EXIF CreateDate tag time delta in seconds between images to be considered part of the same sequence/stack. Default is 2.0. Specify a value of 0 to disable the time delta check - all files will be considered part of a single stack.

So you would add 'maxtimedelta', 0 to your list of parameters.

Thanks, that works. Great tool!

Interesting file sizes:
Sony ARW (lossless compressed): 61MB
Stacked Output DNG: 107MB
Stack Output DNG, compressed in LrC: 38MB
Sony ARW converted to DNG (and compressed): 44MB

I assume the stacked output is less noisy and therefore compresses better.

Right, in theory that should be why. The intermediate DNGs I create during the conversion are uncompressed, and as you've seen, the final stacked output is uncompressed as well. This is necessary to accommodate the method I'm using to access the raw data. A future option I'm considering is running the stacked output DNG through the DNG converter to losslessly compress them, as you just did manually.

Everything worked great Adam!

I've updated Exiftool and DNG converter (13.2) and run this line:
createStackedDngs('/Volumes/Untitled/DCIM/100MSDCF', 'partialstacks', '1/16, 1/8, 1/4, 1/2, 1', 'tempdir', '/Volumes/NVme')

Here is the result:

Running exiftool to retrieve EXIF data on files in "/Volumes/NVme/OctaveRawTools-Temp-161921273681"...

______________________

So, from 956 files, I ended up with 5 DNG files with different "ND strengths": (59, 119, 239, 478 and 956)

Wow, averaging almost 1000 RAWs has never been so easy (or even possible). I did it from the memory card itself and only brought the resulting DNGs into Lightroom.

Question: Would the script know there are different sequences of files and therefore distinct scenes to be averaged just by giving the location of all files in the memory card? If so, could I still use the 'partialstacks' for the difference scenes in the card?

Thanks for the feedback Fred. Btw, you can also specify the output path where the generated stacked files go via the 'outputdir', '<path>' option - that way they wont be written back to your media card when you're ingest directly from it.

Absolutely, in fact that was the primary scenario I designed it for. I wanted to be able to shoot an arbitrary number of different photo sequences to stack separately on a given outing, dump them all into a single folder, then have the script automatically find each set by using the EXIF CreateDate tag. By default it'll consider files part of the same set when the CreateDate value for each is within 2 seconds of the previous image (configurable via the 'maxtimedelta' option).

It's overcast and no wind so not much ND effect. But here is a difference between 16 stack and 256 stack compared to no stack:

What's nice about the mean stacked images is that we can sharpen the files much more without artifacts being introduced, so at the end, not only we get the ND effect, very low noise but we also get sharper images.

The file the Adobe DNG converter is complaining about appears to be prepended with a period: /.__FM94694.ARW

Is that the actual name on the card? Is it a valid raw file?

That's the name of that file but it does not have a period. I came straight from my camera, so yes, it's a valid RAW file.

I made sure the directories are correct and even restarted the machine to make sure. Somehow I'm getting this error even with the very simple script.

I've moved the RAW files from the card to my Desktop and it now works. Somehow it does not work all the time straight from the SD card.

I used the command-line below and it's running now. (1500 images!!! ;-))

createStackedDngs('/Users/fredmiranda/Desktop/RAWS', 'outputdir', '/Users/fredmiranda/Desktop/Stacked' ,'partialstacks', '1/16, 1/8, 1/4, 1/2, 1', 'tempdir', '/Volumes/NVme')

Thanks. My script scans the source directory and invokes the DNG converter with up to 32 files at a time, repeating that until all files are converted. It sounds like a process might be running on your system that's temporarily creating a file with that prepended period.

All I know is that it has to do with the source DIR (SD card). Once I moved the ARWs to my desktop, it worked. It's odd because restarting the computer and removing / reinserting the SD card didn't do the trick. It would always give me the error even though the script was correct.

It's interesting that the resulting stacks are all 122.8 MB for me regardless of how many images were in the stack.

My scripts generate an uncompressed DNG as the stacked output so the size will always be fixed for a given camera model.

It's interesting that the resulting stacks are all 122.8 MB for me regardless of how many images were in the stack.


The size of the output file should not increase with the number of images merged. The output file is of the same resolution as each input file.

Note that with frame averaging "The amount of noise reduction is the square root of the number of captures. If you have 2 captures, you have 0.707 times as much noise. Four captures, half the noise. 16 captures give you one quarter the noise, and 64 captures get you to one eighth." (Jim Kasson)
