That will be a good start - don't forget to meter off the shadopws where you want hints of detail then reduce the exposure by 2 stops to place it on zone III. Should be a piece of cake after that...

Thank you Mark that sounds good advise but as far as downrating asa speeds Mark this may fly in the face of all that has been put forward but since replying earlier to your last comment I have had a really good look though my last prints and negatives, one of which was a roll Pan-F rated at 50 asa and the other was a roll of Tri-X rated at box speed 400 and I am genuinely rather pleased with the results so I am proposing to shoot another roll of each at box speed and then take it from there. I don't want to sound ungrateful for all the help offered and I will explore downrating in due course. Thank you for your help it is much appreciated

No problem. What matters is what works for you. The key word in my (rather lengthy) post is "personal" for both film speed and developing time. If you're getting negatives that you are happy with and produce prints / scans that are easy to work on, then why change anything?

 

If you can get hold of a copy, Barry Thornton's book 'Elements' is a good read.

 

Have fun!

 

Cheers
