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
