Thanks Am, I'll have a play. I'm pretty sure I'm viewing the image, once reduced, at full size, since it is taking up a much smaller area of the screen. If I click on it to zoom in it doesn't change. Probably because the zoom is set to 100% and it already is displayed at 100%??
When I choose it for upload to a
competition it is displayed by the forum before confirming (sorry can't remember the exact process) at a size that is larger than LR showed me. It is this version that looks poor.
When using the LR export function I am choosing a max file size of 250k and telling it to make the longest edge 1024 pixels and PPI of 250. Other than giving it a name that's it.
TBH I'm more worried about MMs statement about
sharpening being needed as part of export. That sounds like, if I spend time carefully
sharpening using high pass filters etc in PS, I then have to use what sounds like a much less controllable "high" "medium" etc process on export, without knowing exactly what the effect will be. I assume I have got that wrong and need to brush up on my exporting process.
Having said that, I've got some of my images printed at over 1 m size, and not had any issue with the resolution. So I can't be doing things that wrong (yes, I've had my eyes tested recently :-))
