Luminar 4 sky replacement and layers.
Answered
Did a search, but couldn't find this anywhere. What is the proper technique to use layers and sky replacement in the same image? For instance, I may want to use AI Enhance, and Remove Color Cast. I would normally add an adjustment layer for the second adjustment. If I want to replace the sky, when and how do I do that? In my attempts, no matter what order I do it in, the original sky bleeds through in the final image. Thanks

That makes sense, and I will create and post a sample in a minute. What I'm asking is to how to accomplish the above. For instance, before sky replacement, I would open an image and apply say, Remove Color Cast. Then I would add an adjustment layer and apply Super Sharp. So, if I want to do those same things and replace the sky, what would be the process?
Thanks -
OK, so I sent this image to L4 and added Blue Sky 1. So far, so good. Then I added an adjustment layer, and as you said, the looks changed. I applied remove color cast. Image still looks good. Then I add a second adjustment layer and applied supersharpt. At that point, the original sky is bleeding through. Below is a 100% screen capture. You can see ghosting of the orignal sky in the blue areas.

I've done a few more and it seems it has nothing to do with layers. Don't know if it's my Windows machine, but depending on the original sky, sometimes the original sky bleeds through. Depending on the new sky, it may or may not be noticeable. Below, the original image is on the right, and the replaced sky on the left. The faint clouds at the upper left of the ship and the dark blue line at the upper right are from the original. I probably wouldn't notice it if I wasn't looking for it, but in some images, it is unusable. The was a Canon raw file, converted to Tiff and brought into L4. All I did was replace the sky.

Thanks. I no longer have that raw file, but here is another. I did an Edit In from Lightroom into Luminar 4. I clicked on AI enhance and then Sky replacement with the last Blue sky option. You can see the results. If I just replace the sky without the AI, it still bleeds through, but isn't as noticeable. If I used one of the first two blue skys with more clouds, it wouldn't be noticeable.

Yes, it would seem the hard part was already accomplished - masking complicated backgrounds. I can only guess why they would release an early beta as a finished product. I have no Luminar 3 history, so I don't know if this is typical. Meanwhile, I have been running some of my previously processed images through "AI Enhance" and "Foliage Enhancer" and liking the results, so there's that.

It would seem (and this is speculation on my part) that some idiot in Skylum management had a PERT chart that said the software would be released on November 22 or whenever) or wouldn't take "but it's not ready" as an answer from the programmers. I was a programmer for 40 years, but usually had a boss that would listen to reason (maybe because he/she was an M.D., not an MBA who thought his/her "management skills" were somehow applicable.

Yeah, it's easy enough to recreate, but Skylum isn't alone. I often have to prove to a vendor that a bug exists that can be easily recreated or tested. After going back and forth for weeks with Adobe, I finally got them to admit that they had been able to recreate the bug. Then they wanted me to submit a separate bug report so they could put it in their list of things to fix.
No thank you. The bug still exists. And they are still bleeding customers.I too was a programmer and fought with marketing on when to release. In all fairness, I think this is a very good product and I'm glad I have it. It's still light years ahead of anything else, and I can work around the issues.

I agree on some of the product features. I've been spritzing up some previously processed photos in a minute or two with a couple of Luminar 4 sliders. And I've only seen one failure of the Sky Replacement masking process so far. I would love an intermediate step where Sky Replacement displays the mask as a hatched pattern or some such. It certainly seems that once the complicated masking process is complete (which it seems to do very quickly), replacing everything in the mask would be simple. And if they can't be bothered to make a User Manual PDF, why not just have a tool tip on each slider saying what the heck they do?

I just emailed this message to Skylum Support:
Anastasia,If you take an image that has clouds, say in the rightmost part of the sky, and replace that sky with an image that has blue sky in that spot, you can see the original clouds, though at some partial opacity. If you then start playing with the "Close Gaps" slider, you can see that Close Gaps does not "set and reset" as you slide it back and forth, but instead works in some sort of additive manner. I think this may be a hint as to what is wrong with the mask or replacement process.At least that's what happens on my computer in Windows 10. -
Darryl,
My workaround is to white out the sky with EasyHDR's (there - I said it!) Intelligent Mask function and then export that image to Luminar 4. I realize that would seem to obviate the need for Luminar 4, but since Luminar 4 DOES seem to be able to make a complicated sky mask, I have a workaround until Skylum fixes Sky Replacement.
-
I haven't seen Luminar 4 Sky Replacement go outside the sky area. I guess it's due to the lack of color contrast between the clouds and the roof of that building - that is to say, the mask it generated wasn't correct? My photos are all mountain landscapes, so there's a lot of contrast.
