I would say your problem is inherent in the total size of your montage. No matter what you start at, you are reducing the pictures down to approximately 100 pixels or less in dimensions. And that means your detail will be degraded no matter what you do. You may try to reduce the size down using various resampling methods for each picture on their own to try and get a better result. But I am not sure you will get results much better. Pixel counts are absolute to the final file and the resolution detail available. All I can recommend you do is to try and increase your total pixel size of our final montage if possible. You may want to try a very large composite to begin with, and then begin to export your final down to various sizes trying various resampling methods as you go. There will be a point where you just won't be able to go any smaller for the detail desired.
Of course these are only my personal observations, and may not be complete. But I feel that it is the crux of your problem.
Hi trinityaffinity,
Welcome to Affinity Forums :)
You are reducing the size of you images considerably so it's natural they will look a bit blurry after the resize and may need some sharpening.
Regarding pixelation, are you seeing them (your montage) on your screen at 100% zoom level? That's how they will be exported and how you should evaluate them.
Any chance you can post a screenshot of the montage at 100% zoom so we can see what are you dealing with?
Thanks.
