Rubbish dumped in Denton (of interest to smartphone users)
Illegal fly tipping is one of my pet hates and sadly it is a growing problem right across the borough. These pictures were taken in Denton Woods and you can only imagine the kind of tramps responsible.
I took the pictures using my Nokia Lumia smartphone, the lighting was poor and as a result the pictures will win no awards, a dedicated SLR camera would undoubtedly have achieved better results, but an SLR camera is also bulky and heavy therefore it is not on your person most of the time, whereas virtually everyone has a mobile phone with them all the time.
I have not included an exact location for the fly tipping, but the secret is in the image. A lot of smartphone users are unaware of Geotagging and it is worth knowing about so here goes: When you take an image on a smartphone or a GPS equipped camera of any description there is digital information contained within the electronic signature of the image known as metadata . All digital images* contain Exif data which provides information such as the type of device used to capture the image, the time and date as well as technical info such as exposure values, focal length and shutter speed. That kind of information is harmless and of not much use to anyone other than professional photographers, but the geotagging of photographs is a different matter.
Geotagging photographs are a fantastic tool for people such as Bill from Walks in Tameside as they can use their smart device to capture an image, and should they forget the exact location of the image at some time in the future, it would be easy to identify where the image was captured due to the embedded and geotagged information.
However geotagging is also a useful tool for criminals and this is why; imagine you have an expensive item in your possession, say for example a Rolex watch. You decide to take a photograph of it on your smartphone to advertise it for sale on the internet or post a picture of it on a forum. Contained within the image metadata is everything a burglar would need to know in relation to where the photograph was taken, so if it was taken in your house, you would be telling potential burglars your address which is something to bear in mind.
*Exif data can be removed using programmes such as Adobe Photoshop and other editing software.
