Re: [darktable-user] Focus Stacking
Hi All, focus stacking is used a lot by scientists when they use microscopes. There are some open source options that should work fine for normal images. I have used Combine ZP with very good results before for macro images. ImageJ I use for microscope images but have not yet tried on macro shots, but it should work. There is also Picoplay which I have not personally tried but I have read that it give good results. cheers On Tue, 21 Apr 2020 at 05:46, jys wrote: > There's more information about using enfuse here: > > https://patdavid.net/2013/01/focus-stacking-macro-photos-enfuse.html > > > On Mon, Apr 20, 2020, at 03:29, Frank J. wrote: > > > I do focus-stacking with the following workflow: > > > > 1.

Re: [darktable-user] Focus Stacking
If your camera body has the capability to stack images within the firmware, and to output both JPG and RAW images already stacked(as so many currently do), why do you need an additional body of work to be added to the post-processing within darktable or Hugin? I'm curious as to the thinking. -- "You don't take a picture. You ask quietly and humbly to borrow it." - Unknown -- On 4/20/20 10:16 AM, Jason Polak wrote: I think darktable won't work very well for stacking. Someone correct me if I'm wrong but I think dartkable's algorithm does not optimize for contrast in different contrast images like you would get in enfuse/enblend. I also do not think darktable does alignment like hugin, so I believe it is not a good idea to use darktable for this specific purpose. Jason On 2020-04-19 2:48 p.m., J.

The reason I am asking is that the stacked jpg made by the camera is so much clearer than the stacked dng file from darktable. I maybe doing this all wrong I am assuming that focus stacking is a form of HDR and used the Create HDR button. Hallo Paul, I do focus-stacking with the following workflow: 1. Export minimal pre-processed pictures of the stack from darktable into a folder. 2. Align the stack with control-points 3. Compose the final picture from sharp parts 4. copy exif-tags to the result (time, camera) 5. re-import the result into darktable for final processing Examples: 1. You can crop the pictures but all must habe the same size. Use copy history stack for all pictures. You can use 16bit TIFF for better quality. 2. align_image_stack -v -m -a algn 20200420_0001.tif 20200420_0002.tif 20200420_0003.tif Without "-a " the dt-exports are overwritten with aligned versions. With "-p file" a *.pto is created. That is a hugin-Projekt for manual interaction. 3. enfuse "$@" --exposure-weight=0 --saturation-weight=0 \ --contrast-weight=1 --hard-mask --contrast-window-size=5 \ --compression=92 --output=stacked.jpg algn*.tif Hugin can be used as a GUI to manually define some inclusion-/exclusion-masks for step 3. But most stacking is well done without hugin. Step 3 can be done from hugin-gui. There is a LUA-Script "enfuse professional" to assist you in this workflow. It can be found at: https://www.multimedia4linux.de/index.php/bildbearbeitung/darktable/darktable-plugin-enfuse-professional But this LUA-Script will not work for a stack from your "Olympus OM-D E-M5 Mk.III" in some cases. The reason is: Olymus has two modes for focus-stacking A. Focus-BKT ON, but Focus-Stacking OFF B. Focus-BKT ON, and Focus-Stacking ON Mode A will take a set auf RAW-Pictures. Beginning with the focussed point, moving to the background. This will work with LUA "enfuse professional". Mode B will take a set of RAW and JPG and will process the stacked picture in the camera as JPG, as you described. The first picture will be taken at the focussed point. Then the focus jumps nearer and then stepwise to the back. Before processing this stack with "align_image_stack" in step 3 you have to *sort this pictures by focus-point*. "align_image_stack" compares the pictures pair-wise in the given order to find the control-points. The first taken picture will not match with the second (nearest). The position of the first picture will be skipped. It is possible that the two pictures before and after this position don't have overlapping sharp areas when this area is very small. When using the LUA-Script "enfuse professional" you have no chance to manually sort the pictures by "fucus-point" without renaming the pictures. Therefore I dont use "enfuse professional" but small shell-scripts (*.sh) on my Linux-System. A correction with hugin is not possible when using "enfuse professional". The aligned files are in /tmp and will be deletet. No chance for taking them for a hugin-project. Take care not to use lens-correction twice, in darktable and in the LUA-Script. The results auf "align_image_stack" + "enfuse" are better then the internal stacking of the camera. I got some results on stacks where the camera fails to stack. Good luck.

No, focus stacking is not a form of HDR (and darktable doesn't do focus stacking). In the first case you take the best focused parts of each image, in the second case you take the best exposed parts (roughly speaking). The algorithms involved in both cases are very different.
