I have filed a few bugs. Definitely not missing or inaccessible files, since a repeat attempt often works.

I have tried many things to fix this problem. The only apparently reliable workaround so far is to disable parallel image loading.
I don't believe it's related to disk space or memory.

I am having this problem too, and I think it started with 9.03.

Randomly, stacks fail with "DNG converter exited with 0X1" or sometimes a message about an exception and the code 1000008.

It appears random and intermittent. I don't believe that I'm running out of temporary file space. I'm using ...

Naively, the way that I would like it to work is that when you "save project", it prompts for a destination, then bundles all needed input images (and needed outputs!!) into a .zip file at the destination. Load project would reverse this.

Typically, my input files are still on the memory card, I ...

Helicon is first in my workflow - I stack right off the card (CF-A 900MB/s). Unless Helicon does repeated uncached reads of the same input file, I don't think I have anything to gain by copying to faster media first.

I use Adobe Raw-to-DNG converter to convert the 14-bit compressed RAW files (~24MB ...

I process several hundred GB of image data in Helicon Focus pretty much every day, and I'm really looking to buy a faster - much faster - desktop setup, but I'm having a hard time finding the benchmark data to make a decision.

All I have seen is high end Windows workstations scoring around 2000 ...

I shoot all my macro hand-held at 120fps, often in windy conditions. Helicon does a fantastic job aligning the images as long as they are spaced closely enough in time and space.

What you describe should work, though the higher the magnification the more difficult it will be to make small consistent focus adjustments manually.
It should be fine for landscape photography type focus stacking. For macro you will probably want a focusing rail.

Pardon my jumping in here with a related comment - Some time ago I brought up adding an option to embed the input files into the save file rather than having external file references. I would still love to see this feature.

Forgive me for chiming in without having a definite answer, but I think that if noise is bad from low light it will almost certainly be better to denoise the source images.

For starters, you could denoise the raw files before they are linearized and make use of "raw denoise" type algorithms in LR ...

So has the situation changed since you wrote this earlier in the thread?

"And you don't need a super powerful CPU if you're going to use OpenCL, something with a better balance between multi-threaded and single-threaded performance should improve the total rendering time over the 64-core monster ...

Came across this 5-year old thread and now I have the same question.

Has anything changed? I would be extremely interested in your current thoughts on configuring a PC for maximum performance. Are the below recommendations still completely current? What would be the current processor and graphics ...

That is not the most helpful response. Is the smoothing parameter not in pixels, or is it another unit?
I am talking about something different than how the sharp parts of source images are combined.

And the image I sent you was just a sample to illustrate the issue, no need for condescending ...

If you graphed focus by depth, a single shot would have a ramp up to a peak, followed by a ramp down. Like the peak of a triangle.
A focus stacked image would have a very steep ramp up, followed by an ideally flat plateau, then a steep ramp down.

This can produce an unnatural looking transition ...

To expand on this: out conclusion was that effects with an absolute thresholds create a lot of artifacts. With the stacks we tried, we didn't like the result. If you have a stack where this worked well and can share it with us - we'd like to take a look.


Thank you for your response. It isn't ...

Ok, thank you.

I'll use the opportunity to point out another very minor issue:

In the rendering view source image list, if you mult-select images for removal, the context menu command "Remove image" should be pluralized, otherwise it is not clear that it will perform the intended action.


Also a ...
