Hello All;
I don't know how many similar tools there are out there, but I wanted to give an example of my Luminar 4 "AI sky replacement tool"
This was my 1st attempt at opening and using the tool. The photo is what I considered a "throw away" I could use to experiment on
One of the 1st of 30 buttons to click on, maybe my 1st, was one of the "galaxy" buttons and this is the photo that appeared. I have started to use the tool seriously to enhance some of my photos lately, nothing like this for sure
I hope this is the appropriate sub forum to be doing this

I returned from a pre-CoVid trip to New Zealand and found many of my pictures had a cloudless or boring sky. I used this tool extensively to rescue many of these pictures for use in a photobook. The ease of use makes it a fun experience. After all, none on this forum will tell my friends what I've done.

Aside from the basically impossible rendition of a night sky from within a city under lighting like that, the sky 'fades out' wherever it meets building edges. I've seen much more convincing shots from Luminar 4, so you'll probably get there with more experience.

Interesting and this one looks quite natural Joseph. It even almost covered the dust bunny you have in the original shot
Mind the bandwidth of others, don't link pictures larger then 1024 wide or 960 pix high, see here

Hi Joseph,

For me, this works so much better than the original one, partly because it is closer to the original and, therefore, the reflections in the building glass don't seem out of place.

It's an interesting 'add on' and would do well in landscapes where nature forces you into taking 'that boring sky' sort of image - at least, with a little careful selection, make something of it.

I must admit I will be keeping an eye open for it's use in my local Camera Club competitions from now on - it's the sort of 'freedom of expression' type of thing that some people would run wild with....

Thanks again and best regards, Neil.

Thank You Pieter for pointing out this Glaring omission which I unforgivably missed, and your knowledgable comment



Hello Neil. Your perception is impeccable! I never even noticed the cloud reflections and how clever the tool is, above and beyond what I saw. To be honest, my difficulty is choosing which of the many sky's to use to replace. I'm sure others would think different sky's would work better than the one I chose.

"it's the sort of 'freedom of expression' type of thing that some people would run wild with...."
You mean like I did in the very top photo? ha ha

Boy, I would be lost without you guys . I'm not even in a local camera club.
Thanks, All the Best_____Joe

Well done Joseph! It seems you are finding your way with this tool.
This last example looks pretty good, without strong and unnatural transitions between the sky and the building.

THe sky replacement tool rescued dozens of photos from a trip to Greece. We were in Kalambaka and for much of the day it was just a blank gray overcast or in order to get proper exposure on a bunch of shots the sky ended up blown out. I thought maybe I could rescue them in photoshop but 30 seconds in Luminar 4 with the sky replacement tool and they are fantastic now.
