Partial pixelation of the image

[Oleg Lozovoy]

Hello Adobe community! After spending some time blending together few exposures for the final image I've noticed some pixelation on the photograph (please check attached image with 100% crop). The question is why did this happen and what can I do to prevent this in my future work? All Raw files which were used for this composite don't have this issue as well as the other final images. All shots were sent from Lightroom to Photoshop via Open as layers in Photoshop button (if it does matter) and auto alligned before editing. Would be grateful for any kind of advice. Thanks!

When you auto align what setting did you choose? This is a simple misalignment where PS did the best it could to match edges.

Your layers should be masked allowing you to edit and adjust the edges manually.

Thanks for your reply Kevin. All layers were aligned with Auto projection mode as usual. Never seen this issue before.

Do you have Geometric Distortion checked? MIght be worth trying with that on.

Either way, there is no 100% guarantee that this will be seamless.

Using the individual layer masks gives you the ability to blend the layers where you see the distortion.
