Hi,
When I use the filter I suppose to see in the preview the clip after the filtered photos
but I always see the full photo so there is no way for me to know what will be the outcome of filtering.
Thank's
Ilan

What do you mean with "full photo"? The full sequence? That's not true. Once the filters have been applied (and curves are fully drawn), by default LRTimelapse will only play back the residual photos (which are not filtered) when you click on play. Check out my long term tutorial on the tutorial page.
