Yes it is, but I think that if you put a ND filter on the front of a TTL flash the output will be regulated for giving the correct exposure (no contrast control), that�s the way the TTL goes, the camera read the exposure, is like if you were trying to underexposure a photo using a ND filter on the lens of the camera, autoexposure will compesate it. Yes contrast control works with the RTF and a external flash, but I think you�ll need the sincro cable. All the ways I think the better option is using main flash in ttl and slave one in AUTO.

Emilio, that's what I am asking about :) But of course with ND filters I mean using TWO flashes in ttl multiflash, one with no ND, the other with ND filter. The Metz brochure on the ND filters for their flashes seems to say (If I understand the German correctly) that you can get sort of "contrast control" effect by using ND filter on one of the two flashes only (which, in a way, makes sense). But I am not sure of it. Also, contrast control works only with one flash and the RTF, no? good light, Frantisek - This message is from the Pentax-Discuss Mail List.
