Long exposure image banding
I quite often experiment with neutral density (ND) filters for long exposure photography as part of images I produce and, over the last couple of years, have had two particular problems (neither of which I have examples of any more so I've pulled in some links from Google Images):

EA DEMs Data Precision
UPDATE: An illuminating and quite hilarious read over here. The release of the LiDAR sourced EA DEMs is garnering some nice attention around the world although Martin spotted that the elevation values are recorded to a precision of attometers. Yes that's 15 to 17 digits after the decimal point!! As Martin points out, this is a huge waste of bandwidth and, I imagine, a default export setting. As I noted yesterday, the interface is functional, if a little clunky, and could do with some improvement.

EA DEMs of UK
As I noted earlier, the EA has now made its 50cm DEM data of the UK available at Data.gov.uk. You can find both the DSM and DTM 50cm products.... From either page you'll eventually get to this download page which is a touch slow but works well enough where you can download fairly small OS tiles (shame they cant be bigger). Ill be playing with these over the next few weeks to see what they are like.

Lies, damned lies....
I was asked to fill in a customer satisfaction survey today using a fairly normal 1-10 symmetrical likert scale. Except that below the scale values 1-6 were noted as "negative", 7-8 as "neutral" and 9-10 as "positive". This psychological bias means that if you are satisfied you should be scoring 9-10.... this will naturally inflate any averaged values which can then be validly used in any marketing.
Clearly even big companies like Aviva aren't too worried about pushing the boundaries of acceptable.

OPEN ACCESS EPRINT: Optimising UAV image quality using consumer cameras
O'Connor, J. and Smith, M.J. (2015)
Surveys using UAVs and photogrammetry are becoming ubiquitous. It is in the community’s best interests to remember the fundamentals of image capture. James O'Connor and Mike J Smith of the School of Geography, Geology and the Environment, Kingston University review the main considerations for image capture when undertaking an aerial survey using consumer grade cameras and make recommendations for acquiring the best imagery.

Its a bit twee in its connotations, but "big data" keeps popping up all over the place. My brother sent me the link to this story: "5 Ways Big Geospatial Data Is Driving Analytics In the Real World". There is nothing overly new or exciting in the actual research itself, however what is interesting is how "geo" is now overtly mainstream. A lot of the benefits and issues associated with geodata are now more widely understood and appreciated meaning that more people want to use it. Definitely boom times...

Be bold, Be Blad
DPReview report on the latest aerial camera range from Hasselblad, the A5D. These are medium format cameras that compete directly with the Phase Range range I reported on earlier (the 80MP iXU180). Three models at 40, 50 and 60 MP, with up to 14 stops dynamic range with a 53x40 or 44x33mm sensor (technical specs here). Weighting in at 1.3kg (body only) its slightly heavier as well.
Clearly the medium format aerial imaging space is heating up a lot - sales are likely much higher than bespoke large format cameras and used across a range of platforms including UAVs. Expect this to get better and cheaper with the competitive drive. Exciting times!

Liam Neeson Kill Map
Clearly Liam is one badass guy!!!! Love the kill map just for the way it presents information that you find yourself asking for during a movie. In my case (re)watching "Taken" and thinking, whats the body count in this?? Star Wars 1 surprised me though.... I wonder who holds the cinematic record?! Anyway, its nicely designed and more as an infographic, but still feel it could be improved.
