I'm guessing 3 or 4 seconds would have been a better exposure time but I thought that was quite short especially with a filter already in place. Do extremely short exposure times impact contrast?

Thanks for any tips you might be able to share.
I believe the Durst M605 has a colour head. If you are using a Multigrade 4 filter, does that mean you are using the head with the filtration switched off/zero filtration values and using the 4 filter underneath the lens?
