For 2023 (and 2024 ...) - we are now fully retired from IT training.
We have made many, many friends over 25 years of teaching about Python, Tcl, Perl, PHP, Lua, Java, C and C++ - and MySQL, Linux and Solaris/SunOS too. Our training notes are now very much out of date, but due to upward compatability most of our examples remain operational and even relevant ad you are welcome to make us if them "as seen" and at your own risk.

Lisa and I (Graham) now live in what was our training centre in Melksham - happy to meet with former delegates here - but do check ahead before coming round. We are far from inactive - rather, enjoying the times that we are retired but still healthy enough in mind and body to be active!

I am also active in many other area and still look after a lot of web sites - you can find an index ((here))
Comparison - with and without flash

Do you Use flash to make a bright scene darker? Not necessarily!

Here's a picture of Melksham Station taken last Sunday night with the available light:



And here's a picture taken a few seconds later, taken with flash:



Flash gives extra fill-in light in the foreground, and with camera adjustment it can actually cause the background to go much darker - quite the opposite of what many new photographers expect. You'll note that the only thing that's at all close to my camera in the these two shots - the blue box to the bottom right of the picture - is lighter in the flashed scene, but darker in the natural light scene. And that's reversed for the rest of the scene.

Flash is ideal for taking pictures of people / filling in close by scenes as it emphasises the close and darkens the background - sometimes to the extent that it makes a photograph that would have been impossible into one that's possible. For the scene above, though, it's counter-productive.

Footnote - there were no trains around at the time I took these pictures; the railway's guidelines for photographers state that you should not use flash to photograph moving trains and - as you can see from the pictures - it would be pretty pointless to do so anyway!
