Yeah I thought most minilab prints were done with digital enlarger type things or something, i didn't realise they were lambda printing... I've only heard of lambda printing in reference to the new ilford B&W stuff that can be used in those printers. I don't do much lab stuff these days, partly because I keep telling myself I'm going to do RA-4 at home one day. From what I've heard from PE, you can do normal RA-4 at room temperature and it's more stable than the RA-4 room temperature kits. Just need to compensate slightly for a colour cast caused by the cooler development.
Anyway that was totally off topic I don't expect many people to do their own colour stuff, especially if this isn't a specific colour analog work exchange.
