Hi, I'm selling a large pouch (as new) condtion on ebay, this is the link if anyone is interested, cheers http://cgi.ebay.co.uk/Panavision-large-AC-...1QQcmdZViewItem

Thanks for the explanation, I understand it now. I?m interested to see the official Peter Merigold explanation of T-stop calibration too, cheers for all the info.

Cheers for all the replies, for the original question what I meant to say was - If my light meter reads say f/4 what would my T-stop be? As light is lost reaching the film plane due to the glass elements in the lens, surely the aperture would need to opened wider than T-4? If so how much?

Im new to posting on this forum, I wondered if anyone could tell me the formular for converting f-stops to T-stops? I carnt seem to find this out anywhere else on the website, Cheers
