I'd like to upload images of a whole city. However to do that I need to blur some windows of buildings, people and cars. Would be nice to do that within the photosynth editor because I guess if I blurr them before synthing it won't work.

Hey adreasbalzer2, do try experimenting with a digital photo editor to blur potions of your photographs.

Depending on how many photos you need to post-process, this sounds like a lot of work, considering you mentioned an "whole city". 

I have performed this type of post-process myself, and found that in a lot of cases, this will not negatively affect the intention of your synth.

I cannot advise you exactly because I have not seen any of your synths.

I should also mention that I am basing this response on my own experiences, and your might not get the same results that I do.

But if you do have a bit of spare time, try the blurring on a small set of images to see what happens and then take it from there.
It might work for you, and then again it might not. But it does not hurt to experiment.

Hi, Andreas,

Jim is right about this. If you have enough shots of the buildings, streets, and landmarks that you are synthing, then the synther won't be using people's faces to figure out the positions of things, anyway (especially if the people are moving - which they usually are). In short, all you have to do is open your photos (before you synth them) in a photo editor (as Jim suggests) select the faces, and perform the blur effect on the selected portions of the photos. I know that it's a lot of work for you to this all manually, but ultimately you are responsible for whatever you upload to the internet.

Bing and Google do have systems in place to do automatic face detection in their Streetside and Street View imagery and blur them en masse, but I don't see them blurring portions of people's geotagged Photosynth photography in any permanent way.

Again, don't be afraid of harming the quality of your synths by blurring just the people in your photos.
