    Hi Deborah, I've been a bit cheeky but I downloaded your images because I've had no issues with Aurora.

    I processed 4 lots of HDR images that I took today, only ticking the alignment box. These were taken hand-held also. All came out really sharp.

    So I opened your files in Aurora and only checked the alignment box, which is my normal procedure if there are no people in the picture. The composite looks out of focus to me, especially zoomed in. It thought one of your brackets had suffered from camera shake. Aurora is pretty good at alignment but if one is too far out, no software will cope.

    So next I imported your images into Lightroom. Image 2 is way out. If I flick through the images on full screen, they should all appear to be the same (except for the exposure). When I do this with yours on image 2, the tree jumps to the left. Either you moved the camera or perhaps did something to the images before importing into Aurora? No HDR software is going to cope with that I'm afraid.

    Hope that helps, Phil

    Did you look at your images again Deborah?

    I don't know what you're seeing Phil but I just checked the 3 images - looked fine.  Unlikely to be camera shake as the lens I was using has VR.,  I just did an HDR merge in Lightroom that worked completely OK.  No alignment issues at all.  I have also edited many HDR brackets successfully in Aurora (previous version) and 2018 and had no problems.  This time there were - that's why I raised the issue with Skylum.

    The 3 images merged just fine in Lightroom.  Here's the link.  If Lr's algorithm aligned the images OK then Aurora's should too. https://we.tl/shazVryUlR

    Hi Deborah, I'm just trying my best to help as I use Aurora a lot and have had no issues. Clearly it worries me if there is a problem with Aurora.

    The 3 original images I download from your link were different. Image 1 & 3 were OK but Image 2 had the tree in a different place (slightly to the right). Maybe there was a glitch when you uploaded them, I don't know. So I've downloaded them again (see attached screenshot), imported them into Lightroom and the same. Image 2 has the tree slightly to the right compared to image 1 & 3.

    If you have them in Lightroom, open up the images full screen. Flick through them with the left and right arrow keys. The tree should not change its position from one image to the other.

    I agree that Lightroom will merge them (I tried and was gobsmacked) and so will Aurora, which speaks volumes about the software. However software is always going to struggle because the images are not identical.

     

    Hope that helps

    All the best, Phil

    Sorry Deborah I meant to mention . . . .  

    When you flick through each image, you may also notice that the horizon moves up and down relative to the others. If the images are misaligned I'm guessing the software algorithm will make a decision about which is the best alignment point. In your case it looks as if it has assigned the tree and by definition the horizon cannot be merged correctly.It will be interesting to see how Skylum respond.

    Kind regards

    Phil

    Mariia, I did my upmost not to personally attack anybody! I did however  point out (respectfully, I hope) that the images that were being merged were not fit for purpose, that's just photographic critique.
