I had a question about a particular point in this video - found around 1:54
the video shows the sketch and the presenter tapping on right section of screen and then
moving finger to left - - to REVEAL - the actual photo of sketch - obviously
this uses some form of mask - but trying to get my head around how it is done
since neither the sketch nor the image move - ONLY the MASK - very nice
and ELEGANT - any ideas on the 'how-to' appreciated....
UPDATE - as per Seb's comment - this can be done with a downloadable 'Design Accelerator':
Visual Effects >> Image Curtain' - still interested to find out how to do from scratch - very nice
