Hi Matt and Andrew,
Thanks for the tips for the image quality - I was actually using the already compressed sizes provided by Flickr. I will export from LR next time with your tips.
Matt - thanks for your comments, I'm experimenting at the moment. ETTR is nice but requires so much time in post-processing! I guess it would take me just as long to get to a nice dark spot, but more difficult on a cycle
Hope to see some of your ETTR!
