Hello, Does anyone happen to know whether the time listed in the A49 table for the Delta 400 refers to the old model or the New Delta? It says 6–8 minutes. Thanks. Best regards, Philipp -- Philipp Köler, Krummesse My photos: http://www2.fotocommunity.de/pc/pc.php4?mypics=8760

No idea, I only measured the Delta 400 New a few days ago. The figures are based on 35mm film. A 49 1+1 24 degrees 30 sec tilt 10.5 min N contrast optimal for diffuser enlargers; if you have a condenser, about 8 mins will do. As I’ve found that the tilt rate has a major influence on the grain pattern, I proceed as follows: the first minute continuously and with vigour, which ensures speed; up to 5 mins, twice every 30 seconds; thereafter, twice per minute. I can’t say whether it makes sense to reduce the movement from the 5th minute onwards; I just tested it by chance, but from the 10th minute onwards you should definitely reduce the rhythm to twice every 2 minutes; this actually results in a finer grain, and there are no issues with unevenness either. This is particularly noticeable with the HP 5; the Delta is somewhat less sensitive in this regard.
