As far as I know, 25%, 50%, 100%, 200% etc. are the only zoom ratios that give an adequate impression of the image.
And that ratios like 33,3%, 66,7% are not recommended for the reason of interpolation.
I know now that there is no adequate screen representation of the sharpening process.
So, some images do not look good at 33,3% after sharpening, but look really OK at 50%.
Does that mean 50% gives you a false sense of security?
And even unsharpened images look fuzzy at 33.3%, but good at 50%.
What's your take on this?
