<p>William,<br>
thank you for your reply, and thank you too for a good "proper" answer. I agree with you about the 80/20 rule being applicable in this case, that's why I'm not holding my breath. I'm sure I'll be using my ND filters for the foreseeable future.<br>
I don't envy you the job of culling your transparencies. I have been through the process myself recently. I only succeeded because I took a very severe attitude towards doing it. Basically, if the picture didn't have any instant impact on me it went in the bin. I binned over 5,000 in all and I don't miss any of them. Don't think sentimentally, think "photographically, is this picture worth keeping". As for the time involved scanning the keepers, I've archived all mine and will only scan them when I need to.<br>
Enjoy your photography.<br>
Paul.</p>
