Problem with stacking using the BKT function in my XT-4

[XTymonFX]

Hi 

I take a series of photos on my XT-4 or XT-3 using the BKT function. Editing in PhotoShop (stacking), unfortunately, often blurry areas appear in the resulting photo. Is it a PhotoShop problem, lack of Fuji plugs or a problem of BKT settings in XT-3 / XT-4 series cameras. I used KIT 18-55 lens or Macro 80mm lens? Below are the BKT function settings in my XT-4 and a sample stacking photo.

 

Samples are here in my google clouds disk: https://drive.google.com/drive/folders/1hKmuaOZGjJxtKQn8Sspl96JRaHaAWqW1?usp=sharing

Do you have samples from the original images used in the stacking? If you post those, it will be easier to see where / when the issues pop up.

Maybe post the problem section from one image and from the images used to make the stacked final image.

I downloaded folder one and ran it through Affinty Photo's Focus Merge -- their name for their version of automated focus stacking and using the very basic instructions found here:

https://digital-photography-school.com/how-to-focus-stack-in-affinity-photo/

I came up with this:

Welcome, dear visitor! As registered member you'd see an image here…

Other than doing that and resizing it for uploading here, I did no editing such as exposure changes etc.

From what I can see, the files are okay, though a couple of them are very soft in all regions, so if you toss those out before trying to stack, you may have better results. -- Using blurry photos in stacking, results in blurry final images. Essentially just use images that have a region in focus.

(Note: I used Affinity Photo version 1, and of course Serif released version 2 today, so folks will have to get that one now as version 1 is apparently no longer for sale.)

I think the author is saying in that article a couple of things, use good files from the start and secondly, these automated processes are not completely foolproof, sometimes the result is not perfect and you just need to be able to fix the problem spots.

Quite possibly, Lightroom has a way to allow you to fix any problems you encounter similar to how Affinity Photo give you the option.

Use auto stack in Fuji xt4 and delete out of fokus frame.

Does PhotoShop give you a way to fix those glitches?

I guess you have to manually.

I can't understand it .

I found several tutorials like these

https://www.photoshopessentials.com/photo-editing/focus-stack-images-photoshop/

https://photoshopcafe.com/focus-stacking-photoshop-tutorial/

which give you a more step by step approach. These create layer masks for each file being used — this approach is still mostly automatic, but you have more control over everything. Because you have access to the layer masks, you can use the usual edit masks stuff to get rid of any bad areas.

p.s. Your files are fine, once the merging is nailed down your final images should also be fine.

Okay, now you can edit the layers’ mask to fix the bad areas. Here is a quick reminder of how to do that.

In essence, you find the layer that has the stuff you want to keep and paint that layer’s mask white — only in those areas you want to keep —- and make sure the layers above that one have their layer masks painted black in those bad areas to let the correct lower layer to show the fixed part.

This part is basic layer masking and editing. You may need to refer to some tutorials to help you along.

I don't know how to edit the masks 

Do you have a simple video tutorial on it?

Give the instructions in that link a try and see how they work for you.

I have some confidence you can get it working, after all, you have the ability to record, edit and post a video listing your efforts so far, that is far more difficult than clicking on a layer mask and painting in an area.
