iPad Photo: Noise amount changes upon Apply. Clip attached.

Recommended Posts

When I apply the Noise filter to an image in Photo for iPad, I see one level or amount of Noise in the preview…then, upon pressing “Apply,” the resulting noise is much less, and this is after selecting 100% Intensity. I’ve experimented with all of the controls for the Noise filter and I can’t get any better (to me) result than the one shown in the clip.

Can anyone share insights as to why the preview shows one thing, but the final result is so drastically different? The character of the noise itself is fine; I’d just like to end up with the same degree of noise I see in the Preview.

Thank you

For sharpen and noise filters, you need to zoom to 100% to get an realistic preview of the result. If zoomed out e.g. 50% the effect is much stronger in preview. This is by design to achieve good performance / snappiness with help of mip maps.
