No I used it to lighten the flowers I was shooting at the time. The Dog shot was spur of the moment as he never sits still. I barely got the shot off as I'm still working out how to use the Weston meter and I had little time before the dog decided to run around chasing tree seeds flying through the air.
Exposure-wise, shadow and highlight detail are even so it's a bang-on exposure. But Delta 100 reindexed at EI80 is +0.3 stop and likely "lost in translation" during the scan. Movement of ±0.3, ±0.6 would be very noticeable on reversal film but can be inconsequential on negs (much grater latitude), and cheap scans (which often auto-correct) mightn't help. At dog-paw level, I like the image anyhow, despite a heavier bias toward tortoise-shell cats.
And, did you reward the sub-woofer for his patience while you beavered with the Weston?
