Hi all,

I am wondering what type of silde films do you guys use for the Macro Photograph y which requires 2x or great macro abitliy.

I was trying to take a picture of my watch with Arca-Swiss F-line Monorail and a 120mm/F5.6 lens. I extented the bellow for 410mm and the bellow extentsion fact or is 11.6 (410^2/120^2) (!!!). My spot meter read 15s/F64 (ISO 100) and it mean s I need to get 384mins exposure time without adding the "film-getting-tired-fac tor" (what is the term?)

Now, I know that there is no film able to exposure for more than 30mins, and I a m wondering what is the film of your choice for this situation. Any suggestions are appreciated and welcomed.Thanks.

Regards,

Danny
