I marvel at your tenacity for this thread - sorting / selecting / scanning / software image-tweaking. It's been a Herculean effort and credit well due to you.
Yesterday I started sifting through several thousand 35mm images, taken 1986-95. I rapidly realised:
1) Back then, there were just as many overcast days!
2) 95% of my shots were taken "front three quarters" and at stations / depots (permits and open days). Only 5% of shots were more "creative" in composition / location.
3) I didn't keep notes and I didn’t keep negs stored with the relevant prints
(I didn't use 35mm slides until mid 1990's and mostly on non railway subjects).. Train information - in many cases - is lost; and some locations I didn't know I'd gone to!
Oh,.for the benefit of hindsight...
