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!
