Re: Strange pattern in rendered DNG file

Pardon me for jumping in - This seems likely to be due to the X-Trans sensor's unusual 6x6 filter array in the raw image. (A lot of RAW software has this issue. There's a nice entry on Wikipedia.) This explains why your JPG works fine. A 16-bit TIF export might be a better choice to retain the dynam...

Re: How to determine the optimal interval size

You should use the sharpest aperture and let the stack build the DOF you need. For Nikon Z cameras and the Nikon 105mm, the camera's shift setting of 4 work well at 1:1 magnification even wide open. (I did a lot of tests!) Smaller steps for larger magnifications of course. Use the electronic shutter...

Re: .jpg vs .raw workflow question

HF has DNG output if you start with raw files. The only issue I have had is that using RAW, Helicon displays the embedded image data which does not reflect adjustments made in ACR. (These are in the companion XMP files.) However, after the DNG is saved, the XMP adjustments are applied, so the DNG lo...

Re: Shooting the moon: Simple question

Pardon me for jumping in ... since you have not had a reply. Helicon's primary job is stacking for focus depth, not mere stacks. It has a panorama mode under the Edit menu that might work for you. If you use Photoshop, selecting all images in your sequence and opening as layers with create a stack. ...

Used all methods … no problems found! And astonishingly fast, especially after the first run!

New HF version installs old DNG Converter

FYI --- The new version of Helicon Focus is installing Adobe DNG Converter 11.3 replacing Version 11.4 released just a few days go.

Should be possible to check the currently installed version of the DNG Converter, compare that to the version you supply and only install if newer.

Re: Saving as 16bit TIFF

Not sure what your source images are, but in In RAW-to-DNG mode, the stack can be saved as a TIFF which will have 16 bits/channel.

Re: Selecting important focus point in stack

I suspect your focus step width on the D850 is too wide. After a good deal of testing with this camera, a step width of 4 seems to work across a broad range of focal lengths, f/stops and subject distances. It may not be the most efficient in terms of number of frames, but should provide a result wit...

And the Nikon Z 6 and Z 7 have focus stack creation built in.

Re: Odd DNG + retouch + Lighroom behaviour

I notice that too, although in Adobe Camera Raw, not LR. I believe that HF creates an internal JPG for the DNG that comes form one of the original frames. In Bridge the retouched image thumbnail looks unchanged, but once opened in PS, all the changes are there.

Re: image appears to be damaged

I do not use Lightroom or any automated import/export. Even on DNG files that produced the 'Image appears damaged' notice, I was able to edit in ACR and import into PS as a Smart Object without any problems. ACR is clearly doing some king of analysis of the DNG file; wish it had a way to export a hi...

Adobe DNG in new HF version 7.5

Looks like the Adobe DNG Converter installed by the new Helicon Focus v7.5 release is one version behind. The Current version is 11.2, as of Jan 24, 2019. Easy to update … thought you would like to know.

Rendered file name 'bug' ...

With the [params] option, the numeric value of the Smoothing control is not part of the suggested file name using the 'C' method. It is displayed on the caption of the thumbnail at the bottom of the display.
