THE WASPS ARE OUT IN THE HEAT

YOU NEED THE WORLD'S WIDEST WIDE ANGLE FOR THIS!

This picture is a screen grab from the National Geographic video on the Mauritanian Iron Ore Train.

The thin line across the image just below the horizon is the train - the wagons are just visible even if you zoom in, showing the distance from which this was filmed. Maybe VR or sacked panoramas would be the only way to view the whole train!

By the way, the video is worth watching, if only to show what a simple life we live. The fishmonger takes the 30 hour trip with fresh fish from the port, rests at home for two days before repeating the trip to make around $50 a week.

GOOGLE PHOTOS - WHERE'S THE AI?

Around a year ago I searched my Google Photos for "snow" and was very disappointed with the large number of false positives it gave. Also that it raised doubts around the false negatives it could be giving which are much harder to quantify or identify.

I have now repeated the search

and found very little change and no obvious improvement. This isn't the picture we get of computers learning and improving.

Google Photos also found an exposure bracketed set in my images and produced an HDR for me, which I show on the right below.

Overlooking the poor quality and the button on the top right, which come from the screen capture, I would think most would agree that the colours go Google's HDR new unrealistic and unpleasing. Again not the performance of a leaning algorithm.

Not a very nice looking posting but hopefully interesting.

Lets have your views.
