Hi Victoria,
 
Never heard of that before but certainly sounds like a good technique.  There are some natural blurred areas but I would say this is quite the mix and they are really looking to blur items that technically, probably would not be blurred.

Is the background already a little soft? I wonder if it might be possible to batch through the frames using Photoshop's new feature that automatically creates mattes based on out of focus pixels?

Hello All,

Ok, so I've got an odd one here.  I am doing VFX for this movie and in two scenes, the folks basically filmed at a location in which they did not have pre-approval.  Soooo, at first they wanted me to attempt to change the entire background so that you could not tell it was the original place.

I spent many days changing out ceiling lights, adding an exit sign, a map on wall, etc but that did not seem to be enough.  After exhausting myself trying to explain that what they were asking was for someone to completely rotoscope out several people, with lots of movement, etc and it just was not doable.  I tried to roto even one person out but with the amount of movement, hair flying around, etc, it was not within my ability.

I think even a roto expert would be shying away from this.  So, that's the background.

Now, the approach has changed to them asking me to give it more of like a camera depth thing where I just blur all of the background.  That too has it's challenges but masking and feathering out a blur adjustment layer is definitely less noticeable than the roto deal.

However, the amount of blur they want seems pretty excessive and as you might imagine, the more blur, the more likely it will be noticeable as you try to gradually feather out edges as the meet the person in the foreground.

I was trying to do something like create a matte using the much lighter background (the wall is white) and then just blur that layer.

So, I'm looking for ideas on an approach that one of you smart folks here might have.

Thanks ahead.

Eric
