Live filter: layer suddenly changed after rasterisation

Recommended Posts

I have a layer with median blur filter applied. When i rasterise it (with filter) - it drastically changes appearance on semitransparent parts. Like blur became not the same before rasterisation. See screenshots

Just noted, that blur starts to look as after rasterisation IF i set zoom to 100. So not rasterisation results are wrong - but viewport depiction of filter applied on non-100% zoom level

Hi IPv6,
When the zoom level is set to a value lower than 100%, live filters/adjustments are dynamically applied to a low-resolution version of your work (called mipmaps) - we do this for performance reasons, to speed up the workflow/rendering within the application - and so what you see on screen is NOT what the filter would look if it was applied to the full size work - often it looks exaggerated depending on the type of filter/adjustment you used. When the zoom level is set to 100% or above, live filters do display accurately because they are applied directly to the full size image and so there's no visible differences between what you see on screen and the real output.

Since some filters also display specific rendering traits when not displayed at 1:1 px (which includes zoom levels above 100%) I recommend to always check everything at 100% zoom.

It is a known technique in software development, but I think the user interface should in some way communicate this to the customer - a simple notification like you notify about other events. Perhaps less intrusive than a dialog box that must be close though.
