TRY AUTO- BLEND L AYERS
Photoshop can focus stack images for you, but it sometimes masks the different images poorly to show strange areas of blur where they should be sharp. It’s still worth giving it a try because sometimes it does a fantastic job, but if it doesn’t, you can stack your images manually. The manual method is really simple. To try the automated feature in Photoshop, stack the images in the same way as step one. Hold down Shift and left click to select all layers. Then go to
Edit> Auto- Blend Layers and select Stack Images. Make sure Seamless Tones and Colors is checked and press OK.
