I've been developing my own colour for the last couple of weeks using Fuji Hunt chemicals (I've made a video of me doing it if anybody is interested - see here) and so far all has been well.
Until last night when I did a new batch but instead of developing Fuji Velvia and Provia, I included some Astia. The results from the Astia have been less than pleasing.. I processed two sheets of the same shot, one velvia, one astia and the astia has a pronounced green cast. It's the three stage process I'm using with 6'30, 6', 6' (Jobo drum with 4 sheets of 5x4 with 2' wash in between and a 4' wash at the end) at 38 degrees. I use the chemicals for a second and third batches with 30" added on to each stage for the second batch and 60" for the third batch..
These were done in the third batch but, like I say, the velvia and provia have been consistent across the different batches and both the velvia and provia versions of the same shot were in the same last batch.
Any suggestions would be appreciated because I'm clueless :-) My next stage was going to be running some astia on it's own through stage one (6'30, 6', 6').
First off I don't really push chemistry anymore. To me I'd rather guarantee more consistent results than save money. I care, you may not.
You are looking at several options: defective film, or some error in exposure. Given that these were both in the last batch, I would say processing is probably not the issue. The Astia looks underexposed. Velvia is also a warmer film, so that may have counteracted some of the coolness of the scene. That's my best guess.
Yep I think it's a case of Velvia's magenta cast cancelling out the scenes greenish yellow tinge. There is definitely a very warm, slightly yellow feel to the astia, which I can only assume has come from me underexposing it. I referred to a digital image taken at the same time and the astia is more correct so, as a friend of mine said, perhaps I've got velvia eyes and need treatment!

There are colour differences somewhere on flickr shown between the films.
Astia has always been good to me, even using Xtol as a first dev and C41 as a colour dev, the results were even then still decently accurate.
