Maco 820C in 5x4 - Will it fog in std DDS ie fidelity?

I have dabbled with Maco 820C in rollfilm and am thinking of trying 5x4, but at £40 a box, want to make sure that it will not fog in std DDS under bright conditions. This may seem a daft question (as how else would you use the stuff), but thought it worth asking as someone mentioned that Kodak HIE could be a problem before being discontinued in 5x4. All rumour and hearsay. Has anyone tried it in 5x4 in std DDS?

Anyone tried the version without the anti-halation dye?

Is it me or is Maco quality control not good. (I had 820C rollfilm backing tape holding the film to backing snag and jam my holder on 5 out of 10 rolls and a pack of their FB warmtone (Chamois base) matt paper all produce streaky prints (NO other papers thru same developer did. I pulled out the last sheet from the 'trial pack 'without development and slightly dark streaks (purple/brown) were visible on the virgin paper)

Why am I so keen to try another maco product?

just curious, but what does the acronym "DDS" stand for? I know it has to do with double sided film holders...but beyond that I'm not sure

I have used IR 820c with good results in "standard" holders. No fogging, except for one - but that holder later fogged EFKE PL100 too, so it's nothing to do with the film.

I have also tried the "Aura" version, but can't really see the big difference. It makes a lot of difference in smaller formats, but in LF? Well, a 0.5mm extra halation doesn't really give the same glop on 4x5" as it does on 35mm...

I do have a fog problem with the Aura. But that's because I develop by inspection in a leaky darkroom, so the anti-halation layer is necessary to shield the emulsion until the development is well underway. I'll try tank (JOBO) next time.

Jeremy, a DDS is a Double Dark Slide. Stupid name for film holders, but then again English isn't my native language

I've used Kodak HIE in standard darkslides with no problems. Just be careful to shield the opening on the end that the sheath goes into from direct sun.
