Scanning with Linux
As we all know, I have gradually moved lots of things I do from Windows to Linux over time, but still have a computer running the Home edition of Windows 10. One of the few things that still runs on Windows 10 is my Epson Perfection V200 Photo scanner. Well it did work well on…

Graphics issues with map mosaics [3]
Continuing from the previous post in this series. Once you have made up some mosaic tiles you need to know how to edit the sidecar files. In this case with the map tiles that come from LDS there are three sidecar files alongside the actual image. We only need to concern ourselves here with the…

Graphics issues with map mosaics [2]
As I wrote in my last post there are problems when you have to scale down imagery significantly. So I am working on a new map mosaic experiment to see what I can do with it. Starting from four tiles at 0.4 metre resolution i.e. 1 pixel measures 0.4 metres on one side, I am…

Graphics issues with map mosaics [1]
Well this is a tricky little number for people like me who are doing things with high resolution images. I am frequently combining high resolution scanned Retrolens stuff with other aerial images and running into some scaling issues. Basically if I have got a Retrolens image at a certain resolution and I have the aerial…

Canon EOS M100 / Computer Upgrade
Well I have been using a Canon EOS M100 for some weeks as a replacement for my SX260 compact which while it still works, has problems with the shutter on the front of the lens jamming. And while the SX260 was sort of a high end travel zoom and I miss its 20x lens, I…

Canon EOS M100 evaluation of low light performance
One area of particular technical superiority of large sensor cameras (DSLRs and MILCs) is that they have a large lens which lets more light in, the result is much better low light performance than compact cameras. With this in mind I set about evaluating the low-light performance of the EOS M100 using trains as subjects.…

Photography notes 03/2018
I used to write on this blog a lot about my digital cameras and photography. Back then I took a lot more photos and even had many thousands of them published online. However in recent years my focus for photography as a hobby has waned and I took down virtually all of my online photos,…

New bits for “old” computers
As of today the new SSD for the bedroom PC (NUC) and the one for the “server” have arrived. The NUC has now got the SSD installed and Xubuntu 18.04 (Bionic) installed on it and the video clips now being downloaded over the wireless from the mediapc. The difference in sound level is quite notable…

Why I no longer have confidence in Flickr
Flickr used to be a great photo site. It was started in 2004 in Canada, but it didn’t stay independent for very long. Yahoo took it over in 2005, and for quite a while it looked good. It was quite distinctive from some of the other photo sharing sites, and has retained a quirkiness all…

Useless Flickr processes and tools
Today I found that Flickr has been flagging some of my own personal photos as “infringing content”. I only discovered this when I downloaded some albums from one of my sites and tried to upload them to another site. I then got a few emails about content being removed that had been previously marked as…
