Morning all. Last night I was printing on our beautiful Leitz V35 -- but we don't have a full frame neg carrier for it Anyhow, right next to it is a gorgeous 4550XL with a complete set of neg carriers, glass and glassless.... Anyhow my question is .... the VC head in this has two "sides" I guess I'll say. One with a switch says "color" and "white light" and then there are two filter / contrast dials. Do the two different sides just correspond to different filtration? Ie, different papers need a different setting? We use Ilford multigrade filters for most everything, always have on all the papers I use ...just wondering which setting I should be using. We seem to not have the manual. Thanks. ps - anyone know if FF neg carriers for the V35 can still be had?
