This article describes a new technology and how it can potentially be used in forensic science. This technology, called Photosynth and made by Microsoft, is a way to organize photos of a particular object so that they are spatially oriented with respect to one another. This means that you can make a 3D image of something by using the 2D photos that were taken. While it was originally intended as a creative way to present photos, it can have an impact on forensics. First responders, forensic technicians, and investigators can put together a photographic image of the crime scene much easier, and without the need for expensive equipment or complicated software. Also, this technology could be used to get shoeprints without having to take molds. After several pictures are taken and put into the system, a 3D image is made. If this image is reversed, than they have a perfect shoeprint. However, this technology is far from becoming a forensic tool. This is because there is no indicator or accuracy. Also, it has to be put through a a lot of testing and validation before it can ever by used.

Three parts of this article which were well presented were the way she explained how 2D photos can be created into 3D with this program. Another well presented point was the “who” can do this such as forensic scientists, investigators and responders. Finally the third thing I found was well presented was how shoeprints can be identified without using molds.
Two things I would suggest were to explain what the new technology was from the beginning and how it is used. I would also recommend to say why it is far from being used by forensic scientists if it can be shown to be useful to them.
One aspect I found interesting where how you can take several 2D photographs and make a 3D picture with the multiple images.
Three things i enjoyed about this article, were how photos, if taken in many, can now produce a 3D image that can be used in forensics. Another thing, i liked how she presented the article, and how she explained about how footprints of a shoe can be used in court with photographs and not having an actual mold.
Two things that i would suggest to be strengthened in this article, is to explain why this information would be skewed and not legit in a court room. Also, to explain further what the new technology is and more of the procedure.
Lastly, the one aspect i found interesting, was that there is now the ability to create a 3D photo of a mold of a shoe, with only regular pictures being taken.
Three things that I likes where how shoeprints can be identified without using molds. Another is how original photos can be made into 3D images. fianlly I liked how there are many different scientists that can use these tools.
Two things that I would change is why this information would be skewed and not admissible in court. Also, I would like to know why this info is so far from being used by forensic scientists.
I found the changing of photos from 2D to 3D very interesting.
